Definitions

  • the invention relates to a system for fixing a light source on a counterparty of a motor vehicle headlamp.
  • the invention in particular, a fastening system which makes it possible to fix different types of light sources incorporating a discharge lamp.
  • the invention finds applications in the automotive field and, more specifically, in the field of light projection for motor vehicles. It finds, in particular, applications for the fixation of a light source with possibility of interchangeability between light sources of different types.
  • light projection devices for motor vehicles are equipped with light sources which can be of different kinds.
  • front projectors vehicles are equipped with light sources that can be two different types, namely: a first kind with a halogen bulb, and a second kind to discharge bulb.
  • the source luminaire is also equipped with a high voltage module which ensures the power supply of the discharge lamp.
  • lamp D1 and D2 lamp there are currently two types of light sources called lamp D1 and D2 lamp.
  • Each of these light sources, or lamps has a discharge bulb, a bulb foot and a high voltage module.
  • the high voltage module is immovably fixed in the case of a D1 lamp and, conversely, removably in the case of a lamp D2.
  • the high voltage module makes integral part of the lamp.
  • the high module voltage is not built into the lamp; it constitutes a piece independent, removably mounted on the lamp.
  • FIG. Figure shows a light source 1 having a discharge bulb 2, a bulb foot 4 and a high voltage module 3.
  • the bulb 2 is fixed solidarily to module 3 at the foot of the bulb foot 4.
  • a reflector 5 is provided with an orifice 6 for passage at a base 7. By the orifice 6 passes the bulb 2.
  • a body 2a of the bulb 2 is housed inside
  • the bulb foot 4 is located outside the reflector 5.
  • a lamp holder 8 circular cylindrical shape, forms an integral part of the reflector 5.
  • the lamp holder 8 and the reflector 5 together form a single and even coin called counterpart 9 of the projector.
  • the lamp holder 8 has for role of supporting the discharge lamp 2. It also allows centering and orienting the discharge bulb 2 inside the reflector 5.
  • the lamp holder 8 may also be a separable part of the reflector 5.
  • the lamp holder 8 is then not an integral part of the reflector; it is fixed solidly to the reflector at the time of mounting the projector.

  • the discharge lamp 2 is surmounted a high voltage module 3, integral with said bulb.
  • This module 3 has a substantially square outer contour with a relatively small footprint compared to a lamp D2 and its module, which will be described later.
  • module 3 is irremovable leads to some disadvantages. Indeed, when a user is eager to change the discharge lamp of a headlamp from his vehicle, for example because that it is failing, it is obliged to change all the bulb and high voltage module. In addition, the change of this whole bulb and high voltage module is relatively difficult because, on the one hand, of the difficulty accessing the D1 lamp and the operations to be performed to remove the faulty set and install the new set and the fact, on the other hand, risks due to the high voltage present in the module. The user is obliged to have the whole thing changed by a professional, which drive, in addition to the cost of all, a cost of labor.
  • FIG. 2 An example of a D2 lamp with its high voltage module is represented in FIG. 2.
  • This FIG. 2 shows a light source 11 including a discharge lamp 12.
  • a high-voltage electrical module 13 is removably attached to the bulb 12 at the location of a foot 14.

  • the body 12a of the bulb 12 is housed inside the reflector 15.
  • the bulb foot 14 is located at the outside of the reflector 15.
  • the lamp D2 comprises a lamp holder 18, for example of circular cylindrical shape, which can make integral part of the reflector 15, or be a separate piece, solidary of the reflector 15.
  • the lamp holder 18 and the reflector 15 together form the counterpart 19 of the projector.
  • the bulb has no electronics associated, that is to say that the high voltage module is independent of the bulb.
  • the high voltage module is not part of integral part of the discharge lamp: it is attached to the bulb after the place the bulb in the reflector. It is therefore possible, during assembly and disassembling the projector, disconnecting the high-voltage module from the bulb.
  • This has a certain advantage over the lamp D1.
  • a lamp D2 it is possible, when the bulb is defective, to change only the bulb and keep the original high voltage module.
  • changing a bulb in a D2 lamp is still more delicate than changing the entire bulb and module for a D1 lamp.
  • the user in the difficult place of access that is a projector, the user must first remove the module, and remove the bulb; he must then change the bulb and put the module back on the bulb, with all the risks inherent to the high voltage in the module. The user is therefore obliged to have the bulb changed by a professional.
  • this type of light source discharge lamp connected to a high-voltage module, shall include means which make it possible, on the one hand, to provide electrical continuity and, on the other hand, a shield to prevent leakage of the electromagnetic field.
  • this type of light source because of the generation of a high voltage by the high voltage module, the light projector is subject to many electromagnetic radiation. In order to avoid a dispersion of the electromagnetic radiation inside the vehicle, a shielding the light projection device is necessary. Indeed, electromagnetic radiation can generate many disturbances in the electrical assembly of the vehicle. Several functions of a current motor vehicle being managed by an electronic system, these electromagnetic disturbances can have consequences serious.
  • the object of the invention is precisely to solve the disadvantages of techniques previously exposed by allowing to fix a light bulb on a projector counterpart, with the same fastening system for a D1 lamp only for a D2 lamp.
  • the invention proposes a system for fixing a light source with a discharge bulb adaptable for different types of light sources.
  • This system is particularly suitable for gas-discharge light sources, such as the D1 and D2 lamps, because it ensures continuity electrical and electromagnetic shielding to prevent field leakage electromagnetic into the vehicle.
  • the invention also relates to a motor vehicle, characterized in that it comprises at least one light projection device previous.
  • Figure 1 already described, shows a longitudinal sectional view a conventional vehicle headlamp with a D1 lamp.
  • Figure 2 already described, shows a longitudinal sectional view a conventional vehicle headlamp with a D2 lamp and a module high tension.
  • Figures 3A and 3B each represent a perspective view of the fixation system of the invention, respectively, in the case where the system is unlocked and in case the system is locked, in the case of a D2 lamp.
  • FIG. 4 represents the fastening system of the assembled invention around a light source D2.
  • FIG. 5 represents the fastening system of the assembled invention around a light source D1.
  • Figs. 6A to 6D show side sectional views and sectional views of the fixing system of the invention, in the case where it's unlocked and in the case where it's locked, for a source luminous D1.
  • Figs. 7A to 7D show side sectional views and sectional views of the fixing system of the invention, in the case where it's unlocked and in the case where it's locked, for a source bright D2.
  • the lamps D1 and D2 have shapes very different from each other. They still have some common, standardized.
  • This common part is the bulb foot. Foot bulb is the rear part of the discharge bulb through which this is attached to the high voltage module.
  • This bulb foot is substantially cylindrical, with the same diameter for the D1 and D2 lamps.
  • height between the neck of the bulb foot and the base of the high voltage module can vary between a D1 lamp and a D2 lamp. Indeed, in the case of a D1 lamp, this height is normalized. On the other hand, in the case of a lamp D2, this height depends on the high voltage module used.
  • the invention therefore proposes to use this characteristic common to two lamps. More specifically, it proposes to fix a fastening system a lamp D1 or a lamp D2 around this common part.
  • the fixation system of the invention is therefore intended to be positioned around the bulb foot of a light source D1 or D2. This fastening system allows to hold and lock the discharge bulb with the door lamp, that is to say the upper part of the counterpart of the projector, in the of the bulb foot.

  • the rigid ring 21 is movable in rotation.
  • the flexible ring 31 is not mobile in rotation with respect to counterparty 19. However, it has a degree of freedom, which is a radial translation, with respect to the counterpart of the projector. In other words, as we will see later, the flexible ring 31 can move radially toward the bulb foot, under the effect of a pressure exerted by the rigid ring 21.
  • the flexible ring 31 is made of a flexible material and electrically conductive, for example a metallic material. He rocks thus an electric function, at the same time, by internal contact on the counterpart and by contact of the contact tabs on the high module voltage.
  • This flexible ring 31 has a relatively circular shape; more precisely, it has a circular shape when the fastening system is in locked position; it is circular by segment, or sector, when the fastening system is in the unlocked position.
  • the flexible ring has a larger tangential pitch at a point than in a another point, that is to say greater at the end of the segment than at the beginning of segment. This can be done by shearing the ring at the end of the segment, this which puts the end of the segment naturally behind the rest of the segment.
  • One or more of these different tongues can ensure, in addition, a pre-hold role of the lamp on the counterpart, before the lamp lock is achieved. This tongue then allows the lamp is stable on the counterpart, in a position ready to be locked.
  • the contact tabs are thin and long so to come into contact with an electrically conductive part of the lamp.
  • the holding tabs are wider than the contact tabs, in order to prevent any change of position of the lamp in the counterpart, when the system is in the locked position.
  • the tongue of positioning is fine and long so as to break into a dwelling of the lamp.

  • One of the sectors may also include a tab of positioning.
  • the flank of the contact tongues may have a shape more or less curve, forming at least one arc of a circle, so as to give flexibility to the tabs to allow better contact with the high module voltage.
  • the holding tongues comprise, in addition to a sidewall 34 and a base 35, a holding arm 37 located in the same plane as the base 35, perpendicular to the sidewall 34 and directed towards the bulb foot 14. It is this arm 37 which serves to maintain the foot in the counterpart, when the fastening system is in its locked position.

  • several holding tabs for example three, distributed symmetrically on the flexible ring, that is to say around the bulb foot, it ensures a fixed positioning of the bulb foot inside the ring flexible and therefore the counterpart.
  • the positioning tab comprises, in addition to a sidewall 34 and a base 35, a housing arm located in the same plane as the base 35, perpendicular to the sidewall 34 and directed towards the bulb foot 14. This arm of housing is intended to fit into a lamp housing for ensure correct single positioning of the bulb in the counterpart.
  • the tabs for holding and all have a flank 34.
  • This sidewall 34 allows these tongues to ensure, in addition to their respective roles of maintaining and positioning, a role of electrical conduction and shielding electromagnetic as well as the contact tabs.
  • the flank of the retaining tabs has approximately the same shape curve as the contact tabs.
  • these tabs for holding and positioning may not have flanks; in this case, they only provide their initial role, namely the maintenance and positioning of the bulb in the counterparty.
  • the flexible ring can be made by cutting and folding in a metal foil whose type of metal and thickness are chosen according the desired flexibility. Tabs can also be folded with different shapes and sizes depending on their role. In particular, contact tabs may have a curved shape ensuring better electrical contact with the lamp.
  • the flexible ring 31 which has just been described, is installed in a rigid ring 21.
  • the sectors of the flexible ring are placed side by side, so that the tab of maintenance of a sector is next to a contact tongue of another sector.
  • the rigid ring 21 is made of a plastic material or metallic. It has a circular shape, by segment.
  • the ring rigid 21 is formed of several segments, for example three, solidary the each other. Each segment forms an arc, connected to another segment by a setback.
  • the ring rigid 21 has three segments 21a, 21b and 21c. Segment 21a (and respectively 21b and 21c) is separated from segment 21b (and respectively 21c and 21a) by a recess 23a (and respectively 23b and 23c).
  • the recesses have the advantage of facilitating gripping of the ring by the user to rotate it.
  • the rigid ring 21 has first lugs 22a, 22b (called also prominent parts) forming cams.
  • first lugs 22a, 22b (called also prominent parts) forming cams.
  • the rigid ring has as many first lugs as the flexible ring has tabs of maintenance.
  • the rigid ring therefore comprises three first lugs, only two being visible in the figure. These pins are intended, in the locked position, to push the holding tabs towards the foot of bulb.
  • the rigid ring may comprise a second lug, not shown on Figure 3A, forming a cam. This second lug is intended, in position locked, to put the positioning tab in a housing of the lamp to ensure correct positioning of said lamp.
  • the rigid ring is made so that the flexible ring is against the inner face of said ring and blocked, upwards, by the lugs of the ring.
  • the flexible ring can also be blocked, towards the low, by other lugs used to secure the entire fastening system on the counterparty.
  • the rigid ring 21 has the role of ensuring the locking and the unlocking the fastening system by a rotation about an axis XX 'of the system, that is to say by a rotation relative to the flexible ring and by compared to the counterparty.
  • the rigid ring is rotatable while the flexible ring is not rotatable relative to the counterparty.
  • the rigid ring may comprise, on its inner face, a boss in hard points to prevent the ring from returning to position free. This allows to unlock but not to return to position free.
  • the fastening system is in position unlocked.
  • the rigid ring is therefore in the open position with respect to the flexible ring.
  • the retaining tabs 32 of the flexible ring are positioned each close to a recess the rigid ring; the lugs 22 of the rigid ring are placed in front of contact tabs and do not press on any tab.
  • the flexible ring is therefore free from any contact or support with a lamp.
  • the flexible ring By turning the rigid ring, for example at an angle of about 40 °, the flexible ring is supported by the lug at its most off-center level, that is to say at the level of the retaining tab.

Description

Domaine de l'inventionField of the invention

L'invention concerne un système de fixation d'une source lumineuse sur une contrepartie d'un projecteur de véhicule automobile. L'invention concerne, en particulier, un système de fixation permettant de fixer différents types de sources lumineuses incorporant une ampoule à décharge.The invention relates to a system for fixing a light source on a counterparty of a motor vehicle headlamp. The invention in particular, a fastening system which makes it possible to fix different types of light sources incorporating a discharge lamp.

L'invention trouve des applications dans le domaine de l'automobile et, plus précisément, dans le domaine de la projection de lumière pour véhicules automobiles. Elle trouve, en particulier, des applications pour la fixation d'une source lumineuse avec possibilité d'interchangeabilité entre des sources lumineuses de types différents.The invention finds applications in the automotive field and, more specifically, in the field of light projection for motor vehicles. It finds, in particular, applications for the fixation of a light source with possibility of interchangeability between light sources of different types.

Etat de la techniqueState of the art

Actuellement, les dispositifs de projection de lumière (ou projecteurs de lumière) pour véhicules automobiles sont munis de sources lumineuses qui peuvent être de différentes sortes. En particulier, les projecteurs avant des véhicules sont équipés de sources lumineuses qui peuvent être de deux sortes différentes, à savoir : une première sorte à ampoule halogène, et une seconde sorte à ampoule à décharge. Dans ce second cas, la source lumineuse est également équipée d'un module haute tension qui assure l'alimentation électrique de l'ampoule à décharge.Currently, light projection devices (or projectors light) for motor vehicles are equipped with light sources which can be of different kinds. In particular, front projectors vehicles are equipped with light sources that can be two different types, namely: a first kind with a halogen bulb, and a second kind to discharge bulb. In this second case, the source luminaire is also equipped with a high voltage module which ensures the power supply of the discharge lamp.

Parmi les sources lumineuses à ampoules à décharge, il existe actuellement deux types de sources lumineuses appelées lampe D1 et lampe D2. Chacune de ces sources lumineuses, ou lampes, comporte une ampoule à décharge, un pied d'ampoule et un module haute tension. Le module haute tension est fixé de manière inamovible, dans le cas d'une lampe D1 et, au contraire, de manière amovible dans le cas d'une lampe D2. Autrement dit, dans le cas d'une lampe D1, le module haute tension fait partie intégrante de la lampe. Dans le cas d'une lampe D2, le module haute tension n'est pas intégré dans la lampe ; il constitue une pièce indépendante, montée de façon amovible sur la lampe.Among the light sources with gas discharge bulbs, there are currently two types of light sources called lamp D1 and D2 lamp. Each of these light sources, or lamps, has a discharge bulb, a bulb foot and a high voltage module. The high voltage module is immovably fixed in the case of a D1 lamp and, conversely, removably in the case of a lamp D2. In other words, in the case of a lamp D1, the high voltage module makes integral part of the lamp. In the case of a D2 lamp, the high module voltage is not built into the lamp; it constitutes a piece independent, removably mounted on the lamp.

Un exemple d'une lampe D1 est représenté sur la figure 1. Cette figure montre une source lumineuse 1 comportant une ampoule à décharge 2, un pied d'ampoule 4 et un module à haute tension 3. L'ampoule 2 est fixée solidairement au module 3 à l'endroit du pied d'ampoule 4. Un réflecteur optique 5 est muni d'un orifice 6 de passage au niveau d'un culot 7. Par l'orifice 6, passe l'ampoule 2. Un corps 2a de l'ampoule 2 est logé à l'intérieur du réflecteur 5. Le pied d'ampoule 4 est situé à l'extérieur du réflecteur 5. Dans l'ensemble de lampe D1 représenté sur la figure 1, un porte lampe 8, par exemple de forme cylindrique circulaire, fait partie intégrante du réflecteur 5. Le porte lampe 8 et le réflecteur 5 forment, ensemble, une seule et même pièce appelée contrepartie 9 du projecteur. Le porte lampe 8 a pour rôle de supporter l'ampoule à décharge 2. Il permet aussi de centrer et d'orienter l'ampoule à décharge 2 à l'intérieur du réflecteur 5.An example of a lamp D1 is shown in FIG. Figure shows a light source 1 having a discharge bulb 2, a bulb foot 4 and a high voltage module 3. The bulb 2 is fixed solidarily to module 3 at the foot of the bulb foot 4. A reflector 5 is provided with an orifice 6 for passage at a base 7. By the orifice 6 passes the bulb 2. A body 2a of the bulb 2 is housed inside The bulb foot 4 is located outside the reflector 5. In the lamp assembly D1 shown in FIG. 1, a lamp holder 8, circular cylindrical shape, forms an integral part of the reflector 5. The lamp holder 8 and the reflector 5 together form a single and even coin called counterpart 9 of the projector. The lamp holder 8 has for role of supporting the discharge lamp 2. It also allows centering and orienting the discharge bulb 2 inside the reflector 5.

Le porte lampe 8 peut aussi être une pièce séparable du réflecteur 5. Le porte lampe 8 ne fait alors pas partie intégrante du réflecteur ; il est fixé solidairement au réflecteur au moment du montage du projecteur. Le porte lampe 8 et le réflecteur forment, dans ce cas aussi, la contrepartie du projecteur.The lamp holder 8 may also be a separable part of the reflector 5. The lamp holder 8 is then not an integral part of the reflector; it is fixed solidly to the reflector at the time of mounting the projector. The door lamp 8 and the reflector form, in this case too, the counterpart of projector.

Dans l'ensemble de lampe D1, l'ampoule à décharge 2 est surmontée d'un module haute tension 3, solidaire de ladite ampoule. Ce module 3 a un contour extérieur sensiblement carré, d'un encombrement relativement faible par rapport à une lampe D2 et son module, qui seront décrits ultérieurement. Cependant, le fait que le module 3 soit inamovible entraíne certains inconvénients. En effet, lorsqu'un utilisateur est désireux de changer l'ampoule à décharge d'un projecteur de son véhicule, par exemple parce qu'elle est défaillante, il est obligé de changer tout l'ensemble ampoule et module haute tension. En outre, le changement de cet ensemble ampoule et module haute tension est relativement délicat du fait, d'une part, de la difficulté d'accès à la lampe D1 et des opérations à effectuer pour retirer l'ensemble défaillant et installer le nouvel ensemble et du fait, d'autre part, des risques dus à la haute tension présente dans le module. L'utilisateur est donc obligé de faire changer l'ensemble par un professionnel, ce qui entraíne, en plus du coût de l'ensemble, un coût de main d'oeuvre.In the lamp assembly D1, the discharge lamp 2 is surmounted a high voltage module 3, integral with said bulb. This module 3 has a substantially square outer contour with a relatively small footprint compared to a lamp D2 and its module, which will be described later. However, the fact that module 3 is irremovable leads to some disadvantages. Indeed, when a user is eager to change the discharge lamp of a headlamp from his vehicle, for example because that it is failing, it is obliged to change all the bulb and high voltage module. In addition, the change of this whole bulb and high voltage module is relatively difficult because, on the one hand, of the difficulty accessing the D1 lamp and the operations to be performed to remove the faulty set and install the new set and the fact, on the other hand, risks due to the high voltage present in the module. The user is obliged to have the whole thing changed by a professional, which drive, in addition to the cost of all, a cost of labor.

Un exemple de lampe D2 avec son module haute tension est représenté sur la figure 2. Cette figure 2 montre une source lumineuse 11 comportant une ampoule à décharge 12. Un module électrique haute tension 13 est fixé de manière amovible sur l'ampoule 12 à l'endroit d'un pied d'ampoule 14. Un réflecteur 15 est muni, à l'endroit du culot 17, d'un orifice de passage 16 laissant passer l'ampoule 12. Le corps 12a de l'ampoule 12 est logé à l'intérieur du réflecteur 15. Le pied d'ampoule 14 est situé à l'extérieur du réflecteur 15. Comme pour la lampe D1, la lampe D2 comporte un porte lampe 18, par exemple de forme cylindrique circulaire, qui peut faire partie intégrante du réflecteur 15, ou bien être une pièce séparée, solidaire du réflecteur 15. Le porte lampe 18 et le réflecteur 15 forment, ensemble, la contrepartie 19 du projecteur.An example of a D2 lamp with its high voltage module is represented in FIG. 2. This FIG. 2 shows a light source 11 including a discharge lamp 12. A high-voltage electrical module 13 is removably attached to the bulb 12 at the location of a foot 14. A reflector 15 is provided at the location of the base 17 with an orifice passage 16 passing the bulb 12. The body 12a of the bulb 12 is housed inside the reflector 15. The bulb foot 14 is located at the outside of the reflector 15. As for the lamp D1, the lamp D2 comprises a lamp holder 18, for example of circular cylindrical shape, which can make integral part of the reflector 15, or be a separate piece, solidary of the reflector 15. The lamp holder 18 and the reflector 15 together form the counterpart 19 of the projector.

Dans l'ensemble de lampe D2, l'ampoule n'a aucune électronique associée, c'est-à-dire que le module haute tension est indépendant de l'ampoule. Autrement dit, le module haute tension ne fait pas partie intégrante de l'ampoule à décharge : il est fixé sur l'ampoule après la mise en place de l'ampoule dans le réflecteur. II est donc possible, lors du montage et du démontage du projecteur, de désolidariser le module haute tension de l'ampoule. Ceci présente un avantage certain par rapport à la lampe D1. En effet, avec une lampe D2, il est possible, lorsque l'ampoule est défaillante, de ne changer que l'ampoule et de conserver le module haute tension initial. Cependant, le changement d'une ampoule dans une lampe D2 est encore plus délicat que le changement de l'ensemble ampoule et module pour une lampe D1. En effet, dans le lieu difficile d'accès qu'est un projecteur, l'utilisateur doit d'abord retirer le module, et retirer l'ampoule ; il doit ensuite changer l'ampoule et remettre le module sur l'ampoule, avec tous les risques inhérents à la haute tension dans le module. L'utilisateur est donc obligé de faire changer l'ampoule par un professionnel.In the D2 lamp assembly, the bulb has no electronics associated, that is to say that the high voltage module is independent of the bulb. In other words, the high voltage module is not part of integral part of the discharge lamp: it is attached to the bulb after the place the bulb in the reflector. It is therefore possible, during assembly and disassembling the projector, disconnecting the high-voltage module from the bulb. This has a certain advantage over the lamp D1. In effect, with a lamp D2, it is possible, when the bulb is defective, to change only the bulb and keep the original high voltage module. However, changing a bulb in a D2 lamp is still more delicate than changing the entire bulb and module for a D1 lamp. Indeed, in the difficult place of access that is a projector, the user must first remove the module, and remove the bulb; he must then change the bulb and put the module back on the bulb, with all the risks inherent to the high voltage in the module. The user is therefore obliged to have the bulb changed by a professional.

On connaít, actuellement des dispositifs destinés à fixer une ampoule sur une contrepartie de lampe D2. Un exemple d'un tel dispositif est une bague fermée. Avec cette bague fermée, dans un premier temps, on fixe le module haute tension à l'ampoule à décharge, puis on loge l'ampoule à décharge dans le réflecteur. On amène ensuite la bague dans la zone de fixation. Pour cela, on fait glisser le module haute tension dans la bague jusqu'à la zone de fixation. On bloque alors par un baïonnettage la bague sur le réflecteur. Une telle bague de fixation n'est pas adaptée pour une source lumineuse D1. En effet, le contour extérieur carré du module haute tension de la source lumineuse D1 s'oppose à son introduction dans la bague fermée ou, alors, cette bague aurait un diamètre trop important pour permettre, par la suite, la fixation de la source lumineuse sur la contrepartie. It is known, currently devices for fixing a light bulb on a lamp counterpart D2. An example of such a device is a closed ring. With this closed ring, at first, we fix the high-voltage module to the discharge bulb, and then lodge the bulb to discharge in the reflector. The ring is then brought into the zone of fixation. For this, we slide the high voltage module in the ring up to the fastening area. The bayonet is then blocked by a bayonet the reflector. Such a fixing ring is not suitable for a source luminous D1. Indeed, the square outer contour of the high voltage module of the light source D1 opposes its introduction into the closed ring or, then, this ring would have a diameter too large to allow, by following, the fixation of the light source on the counterpart.

Il n'est donc pas possible, avec de tels dispositifs, d'interchanger les deux lampes D1 et D2. Autrement dit, un utilisateur ayant un véhicule muni d'une source lumineuse D2 ne peut, ultérieurement, pour des raisons de coût ou de disponibilité, introduire une source lumineuse D1 dans son dispositif de projection de lumière, et inversement.It is therefore not possible, with such devices, to interchange two lamps D1 and D2. In other words, a user having a vehicle equipped with of a light source D2 can not, subsequently, for reasons of cost or availability, introduce a light source D1 into its light projection, and vice versa.

Il existe aussi des systèmes de fixation à ressort destinés soit aux lampes D1, soit aux lampes D2, mais avec impossibilité d'interchanger ces deux types de lampes pour des raisons de géométrie et d'encombrement.There are also spring-loaded fastening systems for either D1 lamps, or to D2 lamps, but with impossibility to interchange these two types of lamps for reasons of geometry and size.

Il existe, par ailleurs, des projecteurs de lumière pour véhicules automobiles ayant des systèmes de verrouillage de lampes permettant le verrouillage de plusieurs types de lampes standards. Un tel système est décrit par exemple dans la demande EP-A-1 108 950.There are, moreover, light projectors for vehicles automobiles with lamp interlock systems allowing the locking of several types of standard lamps. Such a system is described for example in the application EP-A-1 108 950.

Cependant, un tel système n'est pas adapté pour des sources lumineuses à ampoule à décharge. En effet, ce type de source lumineuse à ampoule à décharge, connectée à un module haute tension, doit comporter des moyens qui permettent d'assurer, d'une part, une continuité électrique et, d'autre part, un blindage pour éviter les fuites du champ électromagnétique. En effet, dans ce type de source lumineuse, du fait de la génération d'une haute tension par le module haute tension, le projecteur de lumière est soumis à de nombreux rayonnements électromagnétiques. Afin d'éviter une dispersion du rayonnement électromagnétique à l'intérieur du véhicule, un blindage du dispositif de projection de lumière est nécessaire. En effet, les rayonnements électromagnétiques peuvent générer de nombreuses perturbations dans l'ensemble électrique du véhicule. Plusieurs fonctions d'un véhicule automobile actuel étant gérées par un système électronique, ces perturbations électromagnétiques peuvent avoir des conséquences graves.However, such a system is not suitable for sources luminous discharge lamps. Indeed, this type of light source discharge lamp, connected to a high-voltage module, shall include means which make it possible, on the one hand, to provide electrical continuity and, on the other hand, a shield to prevent leakage of the electromagnetic field. Indeed, in this type of light source, because of the generation of a high voltage by the high voltage module, the light projector is subject to many electromagnetic radiation. In order to avoid a dispersion of the electromagnetic radiation inside the vehicle, a shielding the light projection device is necessary. Indeed, electromagnetic radiation can generate many disturbances in the electrical assembly of the vehicle. Several functions of a current motor vehicle being managed by an electronic system, these electromagnetic disturbances can have consequences serious.

Description détaillée de modes de réalisation de l'inventionDETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

D'après ce qui précède, on comprend que les lampes D1 et D2 ont des formes très différentes l'une de l'autre. Elles ont tout de même une partie commune, normalisée. Cette partie commune est le pied d'ampoule. Le pied d'ampoule est la partie arrière de l'ampoule à décharge par laquelle celle-ci est fixée au module haute tension. Ce pied d'ampoule est sensiblement cylindrique, de même diamètre pour les lampes D1 et D2. Cependant, la hauteur entre le col du pied d'ampoule et la base du module haute tension peut varier entre une lampe D1 et une lampe D2. En effet, dans le cas d'une lampe D1, cette hauteur est normalisée. Par contre, dans le cas d'une lampe D2, cette hauteur dépend du module haute tension utilisé.From the foregoing, it is understood that the lamps D1 and D2 have shapes very different from each other. They still have some common, standardized. This common part is the bulb foot. Foot bulb is the rear part of the discharge bulb through which this is attached to the high voltage module. This bulb foot is substantially cylindrical, with the same diameter for the D1 and D2 lamps. However, height between the neck of the bulb foot and the base of the high voltage module can vary between a D1 lamp and a D2 lamp. Indeed, in the case of a D1 lamp, this height is normalized. On the other hand, in the case of a lamp D2, this height depends on the high voltage module used.

L'invention propose donc d'utiliser cette caractéristique commune aux deux lampes. Plus précisément, elle propose de fixer un système de fixation d'une lampe D1 ou d'une lampe D2 autour de cette partie commune. Le système de fixation de l'invention est donc destiné à être positionné autour du pied d'ampoule d'une source lumineuse D1 ou D2. Ce système de fixation permet de maintenir et de verrouiller l'ampoule à décharge avec le porte lampe, c'est-à-dire la partie haute de la contrepartie du projecteur, à l'endroit du pied d'ampoule.The invention therefore proposes to use this characteristic common to two lamps. More specifically, it proposes to fix a fastening system a lamp D1 or a lamp D2 around this common part. The fixation system of the invention is therefore intended to be positioned around the bulb foot of a light source D1 or D2. This fastening system allows to hold and lock the discharge bulb with the door lamp, that is to say the upper part of the counterpart of the projector, in the of the bulb foot.

Ce système de fixation de l'invention est représenté sur les figures 3A et 3B, dans des vues en perspective. Plus précisément, la figure 3A montre le système dans une position déverrouillée et la figure 3B montre le système dans sa position verrouillée.This fastening system of the invention is shown in FIGS. 3A and 3B, in perspective views. More specifically, Figure 3A shows the system in an unlocked position and Figure 3B shows the system in its locked position.

Sur la figure 3A, on a représenté le système de fixation 20 monté sur la contrepartie 19, dans le cas d'une lampe D2 pour laquelle le module haute tension n'a pas encore été fixé sur le pied d'ampoule 14. Ce système de fixation 20 comporte une bague rigide 21 et un anneau flexible 31. L'anneau flexible 31 est électriquement conducteur. Il est placé à l'intérieur de la bague rigide 21. La bague rigide 21 est mobile en rotation. L'anneau flexible 31 n'est pas mobile en rotation par rapport à la contrepartie 19. Par contre, il a un degré de liberté, qui est une translation radiale, par rapport à la contrepartie du projecteur. Autrement dit, comme on le verra par la suite, l'anneau flexible 31 peut se déplacer radialement, vers le pied d'ampoule, sous l'effet d'une pression exercée par la bague rigide 21.FIG. 3A shows the fastening system mounted on the counterpart 19, in the case of a lamp D2 for which the high module voltage has not yet been attached to the bulb foot 14. This system of fastener 20 comprises a rigid ring 21 and a flexible ring 31. The ring flexible 31 is electrically conductive. It is placed inside the ring rigid 21. The rigid ring 21 is movable in rotation. The flexible ring 31 is not mobile in rotation with respect to counterparty 19. However, it has a degree of freedom, which is a radial translation, with respect to the counterpart of the projector. In other words, as we will see later, the flexible ring 31 can move radially toward the bulb foot, under the effect of a pressure exerted by the rigid ring 21.

L'anneau flexible 31 est réalisé dans un matériau flexible et électriquement conducteur, par exemple une matière métallique. Il assure ainsi une fonction électrique, en même temps, par contact intérieur sur la contrepartie et par contact des languettes de contact sur le module haute tension. Cet anneau flexible 31 a une forme relativement circulaire ; plus précisément, il a une forme circulaire lorsque le système de fixation est en position verrouillée ; il est circulaire par segment, ou secteur, lorsque le système de fixation est en position déverrouillée. En d'autres termes, l'anneau flexible a un écartement tangentiel plus grand en un point qu'en un autre point, c'est-à-dire plus grand en fin de segment qu'en début de segment. Cela peut être réalisé en cisaillant l'anneau en fin de segment, ce qui met la fin du segment naturellement en retrait par rapport au reste du segment.The flexible ring 31 is made of a flexible material and electrically conductive, for example a metallic material. He rocks thus an electric function, at the same time, by internal contact on the counterpart and by contact of the contact tabs on the high module voltage. This flexible ring 31 has a relatively circular shape; more precisely, it has a circular shape when the fastening system is in locked position; it is circular by segment, or sector, when the fastening system is in the unlocked position. In other words, the flexible ring has a larger tangential pitch at a point than in a another point, that is to say greater at the end of the segment than at the beginning of segment. This can be done by shearing the ring at the end of the segment, this which puts the end of the segment naturally behind the rest of the segment.

Cet anneau flexible 31 comporte une pluralité de languettes. Ces languettes peuvent être de plusieurs sortes:

  • les languettes de contact, référencées 33, dont le rôle est d'assurer la continuité électrique et le blindage électromagnétique entre le module haute tension et la contrepartie, par contact avec une partie métallique de la lampe.
  • les languettes de maintien, référencées 32, dont le rôle est d'assurer le maintien en position de l'ampoule dans la contrepartie. Ces languettes de maintien peuvent être, par exemple, au nombre de trois. Elles comportent chacune une position verrouillée et une position déverrouillée. Ces languettes sont mobiles radialement.
  • une languette de positionnement, non visible sur la figure 3A, qui comporte une position verrouillée et une position déverrouillée. Cette languette de positionnement est également mobile radialement. Le rôle de cette languette de positionnement est de rectifier les jeux qu'il peut y avoir entre la lampe et le porte lampe (ou la partie fomant porte lampe de la contrepartie) en poussant la lampe radialement dans un logement en forme de V aménagé dans le porte lampe et décrit plus en détail ultérieurement. Cette languette de positionnement peut aussi constituer une sorte de détrompeur pour le système de fixation.
This flexible ring 31 has a plurality of tongues. These tongues can be of several kinds:
  • the contact tongues, referenced 33, whose role is to ensure the electrical continuity and the electromagnetic shielding between the high voltage module and the counterpart, by contact with a metal part of the lamp.
  • the retaining tabs, referenced 32, whose role is to maintain the position of the bulb in the counterpart. These holding tongues may be, for example, three in number. They each have a locked position and an unlocked position. These tongues are radially movable.
  • a positioning tab, not visible in Figure 3A, which has a locked position and an unlocked position. This positioning tab is also movable radially. The role of this positioning tab is to rectify the games that may be between the lamp and the lamp holder (or the counterpart part lamp holder of the counterpart) by pushing the lamp radially into a V-shaped housing arranged in the lamp holder and described in more detail later. This positioning tab can also be a kind of key to the fastening system.

Une ou plusieurs parmi ces différentes languettes (languettes de maintien, languettes de contact et languette de positionnement) peut assurer, en outre, un rôle de pré-maintien de la lampe sur la contrepartie, avant que le verrouillage de la lampe ne soit réalisé. Cette languette permet alors que la lampe soit stable sur la contrepartie, dans une position prête à être verrouillée.One or more of these different tongues (tongues of holding, contact tabs and positioning tab) can ensure, in addition, a pre-hold role of the lamp on the counterpart, before the lamp lock is achieved. This tongue then allows the lamp is stable on the counterpart, in a position ready to be locked.

Ces languettes ont des dimensions différentes, en fonction de leur type et de leur rôle. Les languettes de contact sont fines et longues de façon à venir en contact contre une partie électriquement conductrice de la lampe. Les languettes de maintien sont plus larges que les languettes de contact, de façon à pouvoir empêcher tout changement de position de la lampe dans la contrepartie, lorsque le système est en position verrouillée. La languette de positionnement est fine et longue de façon à s'introduire dans un logement de la lampe.These tabs have different dimensions, depending on their type and their role. The contact tabs are thin and long so to come into contact with an electrically conductive part of the lamp. The holding tabs are wider than the contact tabs, in order to prevent any change of position of the lamp in the counterpart, when the system is in the locked position. The tongue of positioning is fine and long so as to break into a dwelling of the lamp.

Chaque languette comporte un flanc 34 sensiblement vertical et une base 35 sensiblement horizontale. Le flanc a une extrémité libre et une extrémité commune avec un coté de la base. Le coté de la base opposée au flanc est relié à une collerette 36 qui relie plusieurs languettes entre elles. Les languettes sont réparties selon plusieurs secteurs. Il y a autant de secteurs de languettes qu'il y a de languettes de maintien. Chaque secteur, ou segment, comporte donc une languette de maintien et plusieurs languettes de contact, la languette de maintien étant placée en fin de secteur. L'un des secteurs peut comporter aussi une languette de positionnement.Each tongue has a substantially vertical sidewall 34 and a base 35 substantially horizontal. The flank has a free end and a common end with one side of the base. The opposite side of the base flank is connected to a flange 36 which connects several tabs between them. The tabs are divided into several sectors. There are so many sectors of tabs that there are tabs of maintenance. Each sector, or segment, therefore has a holding tab and several contact tabs, the retaining tab being placed at the end of sector. One of the sectors may also include a tab of positioning.

Le flanc des languettes de contact peut avoir une forme plus ou moins courbe, formant au moins un arc de cercle, de façon à donner une flexibilité aux languettes pour permettre un meilleur contact avec le module haute tension. The flank of the contact tongues may have a shape more or less curve, forming at least one arc of a circle, so as to give flexibility to the tabs to allow better contact with the high module voltage.

Les languettes de maintien comportent, en plus d'un flanc 34 et d'une base 35, un bras de maintien 37 situé dans le même plan que la base 35, perpendiculaire au flanc 34 et dirigé vers le pied d'ampoule 14. C'est ce bras de maintien 37 qui sert à maintenir le pied dans la contrepartie, lorsque le système de fixation est dans sa position verrouillée. On comprend bien qu'avec plusieurs languettes de maintien, par exemple trois, réparties symétriquement sur l'anneau flexible, c'est-à-dire autour du pied d'ampoule, on assure un positionnement fixe du pied d'ampoule à l'intérieur de l'anneau flexible et donc de la contrepartie.The holding tongues comprise, in addition to a sidewall 34 and a base 35, a holding arm 37 located in the same plane as the base 35, perpendicular to the sidewall 34 and directed towards the bulb foot 14. It is this arm 37 which serves to maintain the foot in the counterpart, when the fastening system is in its locked position. We understand well with several holding tabs, for example three, distributed symmetrically on the flexible ring, that is to say around the bulb foot, it ensures a fixed positioning of the bulb foot inside the ring flexible and therefore the counterpart.

La languette de positionnement comporte, en plus d'un flanc 34 et d'une base 35, un bras de logement situé dans le même plan que la base 35, perpendiculaire au flanc 34 et dirigé vers le pied d'ampoule 14. Ce bras de logement est destiné à venir s'insérer dans un logement de la lampe pour assurer un positionnement correct unique de l'ampoule dans la contrepartie.The positioning tab comprises, in addition to a sidewall 34 and a base 35, a housing arm located in the same plane as the base 35, perpendicular to the sidewall 34 and directed towards the bulb foot 14. This arm of housing is intended to fit into a lamp housing for ensure correct single positioning of the bulb in the counterpart.

Dans le cas des figures 3A et 3B, les languettes de maintien et de positionnement comportent toutes un flanc 34. Ce flanc 34 permet à ces languettes d'assurer, en plus de leur rôle respectif de maintien et de positionnement, un rôle de conduction électrique et de blindage électromagnétique au même titre que les languettes de contact. Dans ce cas, le flanc des languettes de maintien a approximativement la même forme courbe que les languettes de contact.In the case of FIGS. 3A and 3B, the tabs for holding and all have a flank 34. This sidewall 34 allows these tongues to ensure, in addition to their respective roles of maintaining and positioning, a role of electrical conduction and shielding electromagnetic as well as the contact tabs. In that case, the flank of the retaining tabs has approximately the same shape curve as the contact tabs.

Dans une variante, ces languettes de maintien et de positionnement peuvent ne pas comporter de flanc ; dans ce cas, elles assurent uniquement leur rôle initial, à savoir le maintien et le positionnement de l'ampoule dans la contrepartie.In a variant, these tabs for holding and positioning may not have flanks; in this case, they only provide their initial role, namely the maintenance and positioning of the bulb in the counterparty.

L'anneau flexible peut être réalisé par découpe et pliage dans une feuille métallique dont le type de métal et l'épaisseur sont choisis en fonction de la flexibilité souhaitée. Les languettes peuvent aussi être pliées avec des formes et des tailles différentes en fonction de leur rôle. En particulier, les languettes de contact peuvent avoir une forme courbe assurant un meilleur contact électrique avec la lampe.The flexible ring can be made by cutting and folding in a metal foil whose type of metal and thickness are chosen according the desired flexibility. Tabs can also be folded with different shapes and sizes depending on their role. In particular, contact tabs may have a curved shape ensuring better electrical contact with the lamp.

L'anneau flexible 31, qui vient d'être décrit, est installé dans une bague rigide 21. Les secteurs de l'anneau flexible sont placés côte à côte, de façon à ce que la languette de maintien d'un secteur soit à coté d'une languette de contact d'un autre secteur. The flexible ring 31, which has just been described, is installed in a rigid ring 21. The sectors of the flexible ring are placed side by side, so that the tab of maintenance of a sector is next to a contact tongue of another sector.

La bague rigide 21 est réalisée dans une matière plastique ou métallique. Elle a une forme circulaire, par segment. Autrement dit, la bague rigide 21 est formée de plusieurs segments, par exemple trois, solidaires les uns des autres. Chaque segment forme un arc de cercle, relié à un autre segment par un décrochement. En particulier, sur la figure 3A, la bague rigide 21 comporte trois segments 21a, 21b et 21c. Le segment 21 a (et respectivement 21 b et 21 c) est séparé du segment 21 b (et respectivement 21 c et 21 a) par un décrochement 23a (et respectivement 23b et 23c). Ces décrochements présentent, par ailleurs, l'avantage de faciliter la préhension de la bague par l'utilisateur pour lui faire subir une rotation.The rigid ring 21 is made of a plastic material or metallic. It has a circular shape, by segment. In other words, the ring rigid 21 is formed of several segments, for example three, solidary the each other. Each segment forms an arc, connected to another segment by a setback. In particular, in FIG. 3A, the ring rigid 21 has three segments 21a, 21b and 21c. Segment 21a (and respectively 21b and 21c) is separated from segment 21b (and respectively 21c and 21a) by a recess 23a (and respectively 23b and 23c). These In addition, the recesses have the advantage of facilitating gripping of the ring by the user to rotate it.

La bague rigide 21 comporte des premiers ergots 22a, 22b (appelés aussi parties proéminentes) formant des cames. En fait, la bague rigide comporte autant de premiers ergots que l'anneau flexible a de languettes de maintien. Dans le cas de la figure 3A, la bague rigide comporte donc trois premiers ergots, deux seulement étant visibles sur la figure. Ces ergots sont destinés, en position verrouillée, à pousser les languettes de maintien vers le pied d'ampoule.The rigid ring 21 has first lugs 22a, 22b (called also prominent parts) forming cams. In fact, the rigid ring has as many first lugs as the flexible ring has tabs of maintenance. In the case of FIG. 3A, the rigid ring therefore comprises three first lugs, only two being visible in the figure. These pins are intended, in the locked position, to push the holding tabs towards the foot of bulb.

La bague rigide peut comporter un second ergot, non représenté sur la figure 3A, formant une came. Ce second ergot est destiné, en position verrouillée, à mettre la languette de positionnement dans un logement de la lampe afin d'assurer un positionnement correct de ladite lampe.The rigid ring may comprise a second lug, not shown on Figure 3A, forming a cam. This second lug is intended, in position locked, to put the positioning tab in a housing of the lamp to ensure correct positioning of said lamp.

La bague rigide est réalisée de façon à ce que l'anneau flexible soit tout contre la face intérieure de ladite bague et bloqué, vers le haut, par les ergots de la bague. L'anneau flexible peut également être bloqué, vers le bas, par d'autres ergots utilisés pour fixer l'ensemble du système de fixation sur la contrepartie.The rigid ring is made so that the flexible ring is against the inner face of said ring and blocked, upwards, by the lugs of the ring. The flexible ring can also be blocked, towards the low, by other lugs used to secure the entire fastening system on the counterparty.

La bague rigide 21 a pour rôle d'assurer le verrouillage et le déverrouillage du système de fixation par une rotation autour d'un axe XX' du système, c'est-à-dire par une rotation par rapport à l'anneau flexible et par rapport à la contrepartie. Autrement dit, la bague rigide est mobile en rotation tandis que l'anneau flexible n'est pas mobile en rotation, par rapport à la contrepartie.The rigid ring 21 has the role of ensuring the locking and the unlocking the fastening system by a rotation about an axis XX 'of the system, that is to say by a rotation relative to the flexible ring and by compared to the counterparty. In other words, the rigid ring is rotatable while the flexible ring is not rotatable relative to the counterparty.

En outre, la bague rigide peut comporter, sur sa face intérieure, un bossage en points durs destiné à éviter que la bague ne revienne en position libre. Cela permet donc de déverrouiller mais pas de repasser en position libre.In addition, the rigid ring may comprise, on its inner face, a boss in hard points to prevent the ring from returning to position free. This allows to unlock but not to return to position free.

Dans le cas de la figure 3A, le système de fixation est en position déverrouillée. La bague rigide est donc en position ouverte par rapport à l'anneau flexible. Dans cette position, les languettes de maintien 32 de l'anneau flexible sont positionnées chacune à proximité d'un décrochement de la bague rigide ; les ergots 22 de la bague rigide sont placés devant des languettes de contact et n'appuient sur aucune languette. L'anneau flexible est donc libre de tout contact ou appui avec une lampe.In the case of FIG. 3A, the fastening system is in position unlocked. The rigid ring is therefore in the open position with respect to the flexible ring. In this position, the retaining tabs 32 of the flexible ring are positioned each close to a recess the rigid ring; the lugs 22 of the rigid ring are placed in front of contact tabs and do not press on any tab. The flexible ring is therefore free from any contact or support with a lamp.

En tournant la bague rigide, par exemple d'un angle d'environ 40°, l'anneau flexible est appuyé par l'ergot à son niveau le plus décentré, c'est-à-dire au niveau de la languette de maintien. Chaque ergot 22a, 22b vient alors en appui contre une languette de maintien 32a, 32b, poussant cette languette vers le pied d'ampoule 14. Sous l'effet de la poussée par l'ergot, la languette de maintien se retrouve à proximité du pied d'ampoule, voire en appui contre le pied d'ampoule, ce qui permet d'empêcher l'ampoule de bouger dans la contrepartie.By turning the rigid ring, for example at an angle of about 40 °, the flexible ring is supported by the lug at its most off-center level, that is to say at the level of the retaining tab. Each pin 22a, 22b then comes resting against a retaining tab 32a, 32b pushing this tongue towards the bulb foot 14. Under the effect of the pushing by the pin, the tongue of maintenance is found near the foot of bulb, even in support against the bulb foot, which prevents the bulb from move in the counterpart.

La figure 3B montre le système de fixation de l'invention dans une position verrouillée, c'est-à-dire après rotation de la bague rigide. Cette figure montre que, dans cette position verrouillée, les ergots 22c, 22a de la bague rigide 21 appuient sur les languettes de maintien 32c, 32a de l'anneau flexible 31. Les languettes de maintien sont alors poussées vers l'intérieur du système, c'est-à-dire vers le pied d'ampoule 14. Elles peuvent ainsi être en appui contre la lampe et, en particulier, le pied d'ampoule.Figure 3B shows the fastening system of the invention in a locked position, that is to say after rotation of the rigid ring. This figure shows that, in this locked position, the lugs 22c, 22a of the ring rigid 21 press on the retaining tabs 32c, 32a of the ring 31. The retaining tabs are then pushed into the interior of the system, that is to say towards the bulb foot 14. They can thus be in support against the lamp and, in particular, the bulb foot.

Ainsi, lorsque le système de fixation est verrouillé autour de l'ampoule, comme montré sur la figure 3B, le module haute tension peut alors être placé autour du pied d'ampoule. Le module haute tension se trouve alors en contact avec tout ou partie des languettes de contact 33, ce qui crée un contact électrique entre le module haute tension et ces languettes. En plus de ce contact électrique, les languettes de contact permettent de faire écran aux rayonnements électromagnétiques émis entre le module haute tension et la contrepartie. On assure ainsi un blindage électromagnétique entre le module haute tension et la contrepartie.Thus, when the fastening system is locked around the bulb, as shown in FIG. 3B, the high voltage module can then be placed around the bulb foot. The high voltage module is then in contact with all or part of the contact tabs 33, which creates a electrical contact between the high voltage module and these tabs. More of this electrical contact, the contact tabs make it possible to electromagnetic radiation emitted between the high-voltage module and the other point of view. This ensures an electromagnetic shielding between the High voltage module and the counterpart.

La figure 4 représente le système de fixation de l'invention monté autour d'une source lumineuse D2, lorsque le système est verrouillé. Cette figure montre la contrepartie 19 du projecteur, avec son réflecteur 15 et son porte lampe 18, sur laquelle est monté le système de fixation 20 de l'invention et la lampe D2. On voit, sur cette figure 4, que les languettes de contact 33 du système de fixation 20 sont en contact électrique avec le module haute tension de la source lumineuse D2. Plus précisément, dans le cas d'une lampe D2, les languettes de contact sont en contact avec le connecteur de la lampe D2. Les languettes de maintien 32 sont en appui contre le pied d'ampoule.FIG. 4 represents the fastening system of the assembled invention around a light source D2, when the system is locked. This Figure shows the counterpart 19 of the projector, with its reflector 15 and its lamp holder 18, on which is mounted the fixing system 20 of the invention and the lamp D2. We see, in this figure 4, that the tabs of contact 33 of the fastening system 20 are in electrical contact with the high voltage module of the light source D2. More specifically, in the case of a lamp D2, the contact tongues are in contact with the lamp connector D2. The holding tongues 32 are in support against the bulb foot.

La figure 5 représente le système de fixation de l'invention monté autour d'une source lumineuse D1, lorsque le système est verrouillé. Cette figure 5 montre la contrepartie 9 du projecteur, avec le réflecteur 5 et le porte lampe 8, sur laquelle est monté le système de fixation 20 de l'invention et la lampe D1. On voit, sur cette figure 5, que les languettes de contact 33 du système de fixation 20 sont en contact électrique avec la lampe D1, par une partie métallique de la lampe située sous le connecteur 3.FIG. 5 represents the fastening system of the assembled invention around a light source D1, when the system is locked. This FIG. 5 shows the counterpart 9 of the projector, with the reflector 5 and the door lamp 8, on which is mounted the fixing system 20 of the invention and the D1 lamp. It can be seen in this FIG. 5 that the contact tabs 33 of the fastening system 20 are in electrical contact with the lamp D1, by a metal part of the lamp under the connector 3.

Dans l'exemple de la figure 5, des languettes de contact ne sont pas présentes sur toute la circonférence de l'anneau flexible, mais sur des parties seulement. Par exemple, la zone sur laquelle un ergot va être mis en rotation peut ne pas comporter de languette de façon à faire une surface plane entre la position initiale et la position finale de l'ergot, c'est-à-dire entre la position déverrouillée et la position verrouillée de l'ergot.In the example of Figure 5, contact tabs are not present all around the circumference of the flexible ring, but on parts only. For example, the area on which a pin will be rotated may not have a tab to make a flat surface between the initial position and the final position of the pin, that is to say between the position unlocked and the locked position of the lug.

Dans le cas des figures 3A et 3B, par contre, il y a des languettes de contact réparties sur toute la circonférence de l'anneau flexible. Dans ce cas, c'est la forme tangentielle, ou circulaire par segment, de l'anneau qui permet le fait que les ergots n'appuient sur aucune languette jusqu'à la position verrouillée.In the case of FIGS. 3A and 3B, however, there are tabs of contact distributed over the entire circumference of the flexible ring. In that case, it is the tangential, or circular, segmental shape of the ring that allows the fact that the lugs do not press on any tongue to the position locked.

Les figures 4 et 5 montrent que l'espace entre le système de fixation 20 et le module haute tension 3 d'une lampe D1 est plus faible que celui entre le système de fixation et le module haute tension d'une lampe D2. Par ailleurs, le module d'une lampe D1 a une forme carrée dont la base a des dimensions supérieures au diamètre du système de fixation. Au contraire, la base du module de la lampe D2 a un diamètre inférieur à celui du système de fixation. Les languettes de contact ont donc des dimensions différentes dans le cas d'un système pour lampe D1 et d'un système pour lampe D2. En particulier, les languettes de contact pour lampe D2 sont plus longues que les languettes de contact pour lampe D1, puisqu'elles viennent en contact avec le module lui-même. Au contraire, les languettes de contact pour lampe D1 viennent en contact avec une partie situées en dessous du module, c'est-à-dire plus proche du pied d'ampoule; elles sont donc plus courtes. La courbure des languettes de contact peut aussi varier en fonction de la lampe considérée.Figures 4 and 5 show that the space between the fastening system 20 and the high voltage module 3 of a lamp D1 is weaker than that between the fixing system and the high voltage module of a lamp D2. By elsewhere, the module of a lamp D1 has a square shape whose base has dimensions greater than the diameter of the fastening system. On the contrary, base of the lamp module D2 has a smaller diameter than the system of fixation. The contact tabs therefore have different dimensions in the case of a lamp system D1 and a lamp system D2. In particular, the contact tongues for lamp D2 are longer than the contact tabs for lamp D1, since they come into contact with the module itself. On the contrary, the lamp contact tabs D1 come into contact with a part located below the module, that is to say closer to the bulb foot; they are therefore shorter. The curvature of the contact tabs may also vary depending on the lamp considered.

Le système de fixation de l'invention est donc identique pour des lampes D1 et pour des lampes D2, excepté l'anneau flexible qui peut présenter des longueurs de languettes différentes. Comme on le comprendra par la suite, cette différence n'est pas gênante, dans le sens où elle ne gêne en rien l'interchangeabilité des lampes.The fastening system of the invention is therefore identical for D1 lamps and for D2 lamps, except the flexible ring which can have different tongue lengths. As will be understood afterwards, this difference is not a problem, in the sense that it does not hinder in no way the interchangeability of the lamps.

Quelle que soit la lampe, D1 ou D2, le système de fixation est positionné et fixé selon le procédé suivant : tout d'abord le système de fixation est réalisé en assemblant l'anneau flexible, adapté à une lampe D1 ou à une lampe D2, avec la bague rigide, puis en insérant ce système verticalement sur la partie supérieure de la contrepartie. Le système est alors fixé sur cette contrepartie par des moyens classiques, par exemple, en force, par baïonnettage ou par encliquetage. Le système de fixation peut comporter, dans sa partie située en dessous de l'anneau flexible, des ergots permettant de fixer le système de fixation sur la contrepartie du projecteur.Regardless of the lamp, D1 or D2, the fixing system is positioned and fixed according to the following procedure: first of all the system of fixing is done by assembling the flexible ring, adapted to a D1 lamp or to a lamp D2, with the rigid ring, then inserting this system vertically on the top of the counterpart. The system is then fixed on this counterpart by conventional means, for example, in force, by bayonet or snap. The fixing system can have, in its part located below the flexible ring, lugs to fix the mounting system on the counterpart of the projector.

Dans le cas d'une lampe D1, la lampe est positionnée sur le système de fixation en plaçant l'ampoule à décharge à l'intérieur de la contrepartie, dans un logement en forme de V de la contrepartie. La position de la lampe D1 dans le système de fixation est correcte lorsque la languette de positionnement est en appui contre la lampe D1, poussant ladite lampe au fond du logement en V. Lorsque la lampe D1 est correctement insérée dans le système de fixation, le système de fixation est mis en position verrouillée par baillonettage, c'est-à-dire par une rotation de la bague rigide autour de l'axe XX' et donc une rotation de la bague rigide par rapport à l'anneau flexible.In the case of a lamp D1, the lamp is positioned on the system fastening by placing the discharge bulb inside the counterpart, in a V-shaped accommodation of the counterparty. The position of the lamp D1 in the fastening system is correct when the tongue of positioning is in support against the lamp D1, pushing said lamp to bottom of the V-shaped housing. When the D1 lamp is properly inserted into the fastening system, the fastening system is put in locked position by gagging, that is to say by a rotation of the rigid ring around the axis XX 'and therefore a rotation of the rigid ring relative to the ring flexible.

Dans le cas d'une lampe D2, l'ampoule à décharge est placée à l'intérieur de la contrepartie, le pied d'ampoule étant positionné sur le système de fixation. La position de la lampe D2 dans le système de fixation est correcte lorsque la lampe se trouve dans le logement en forme de V de la contrepartie et que la languette de positionnement est en appui contre la lampe D2, poussant celle-ci au fond du logement en V. Lorsque l'ampoule de la lampe D2 est correctement insérée dans la contrepartie, le système de fixation est mis en position verrouillée par baillonettage, c'est-à-dire par une rotation de la bague rigide autour de l'axe XX' et donc une rotation de la bague rigide par rapport à l'anneau flexible. Le module haute tension peut alors être mis en place sur le pied d'ampoule.In the case of a D2 lamp, the discharge lamp is placed in inside the counterpart, the bulb foot being positioned on the fastening system. The position of the D2 lamp in the fixing system is correct when the lamp is in the V-shaped housing of the counterpart and that the positioning tab bears against the D2 lamp, pushing it to the bottom of the V-shaped housing. the lamp D2 is correctly inserted into the counterpart, the system of fastening is put in the locked position by gagging, that is by a rotation of the rigid ring about the axis XX 'and therefore a rotation of the rigid ring relative to the flexible ring. The high voltage module can then be set up on the bulb foot.

La languette de positionnement est une lame ressort qui permet de pousser la lampe au fond du logement en forme de V réalisé dans la contrepartie. Le rôle de cette languette de positionnement est de rattraper les jeux qu'il peut y avoir entre la lampe et la contrepartie en poussant la lampe radialement dans le logement en V aménagé dans la contrepartie. Pour cela, la languette de positionnement est placée radialement à l'opposé du V. La bague rigide, lorsqu'elle est mise en position verrouillée, a un ergot qui pousse la languette de positionnement vers le centre du système, poussant la lampe radialement de façon à ce qu'elle soit calée dans le logement en forme de V de la contrepartie.The positioning tab is a spring blade that allows push the lamp to the bottom of the V-shaped housing made in the counterparty. The role of this positioning tab is to catch up with games that can be between the lamp and the counterpart by pushing the lamp radially in the V-shaped housing in the counterpart. For that, the positioning tab is placed radially opposite the V. rigid ring, when it is placed in the locked position, has a lug which pushes the positioning tab towards the center of the system, pushing the lamp radially so that it is wedged in the housing in V-shape of the counterpart.

La languette de positionnement peut aussi servir de détrompeur, lors du montage de la lampe sur la contrepartie, c'est-à-dire qu'elle offre une seule position possible lors du montage.The positioning tab can also be used as a key, when the fitting of the lamp to the counterpart, that is to say that it offers a only possible position during assembly.

Lorsque la lampe est montée dans la contrepartie, les languettes de maintien viennent alors maintenir la lampe dans cette position.When the lamp is mounted in the counterpart, the tabs of then maintain the lamp in this position.

Sur les figures 6A et 6C, on a représenté des vues de coté en coupe du système de fixation de l'invention, dans le cas d'une lampe D1, lorsque le système est, respectivement, déverrouillé et verrouillé. Les figures 6B et 6D représentent des vues de dessus du système de fixation de l'invention, dans le cas d'une lampe D1, lorsque le système est, respectivement, déverrouillé et verrouillé. Les figures 6A et 6B montrent la position de la bague rigide 21 et de l'anneau flexible 31 lorsque le système est déverrouillé. En particulier, elles montrent la position des premiers ergots 22a, 22b, 22c de la bague rigide par rapport aux languettes de maintien 32a, 32b, 32c de l'anneau flexible. Ces figures montrent également la position du second ergot 28 par rapport à la languettes de positionnement 38 de l'anneau flexible 31. En position déverrouillée, la languette de positionnement 38 est logée dans un logement du pied d'ampoule, mais elle est en biais dans ce logement. Le verrouillage du système permet à cette languette d'exercer une poussée radiale sur la lampe afin de pousser la lampe au fond du logement en forme de V de la contrepartie. Ce logement en V est représenté sur la figure 6B par deux méplats 40 situés, radialement, à l'opposé du logement 39 recevant la languette de positionnement 38. Ces figures 6A et 6B montrent aussi le positionnement des languettes de contact 33, entre les languettes de maintien 32. On peut ainsi voir aisément les différences de taille qu'il peut y avoir entre les différentes sortes de languettes.In FIGS. 6A and 6C, sectional side views are shown in section of the fixing system of the invention, in the case of a lamp D1, when the system is, respectively, unlocked and locked. Figures 6B and 6D represent top views of the fastening system of the invention, in the case of a lamp D1, when the system is, respectively, unlocked and locked. Figures 6A and 6B show the position of the rigid ring 21 and the flexible ring 31 when the system is unlocked. In particular, they show the position of the first lugs 22a, 22b, 22c of the ring rigid relative to the retaining tabs 32a, 32b, 32c of the ring flexible. These figures also show the position of the second lug 28 by relative to the positioning tabs 38 of the flexible ring 31. In unlocked position, the positioning tongue 38 is housed in a housing the bulb foot, but it is angled in this housing. The locking the system allows this tab to exert a push radial on the lamp to push the lamp to the bottom of the housing fit V's counterparty. This V-shaped housing is shown in FIG. two flats 40 located, radially, opposite the housing 39 receiving the positioning tab 38. These FIGS. 6A and 6B also show the positioning of the contact tabs 33, between the tabs of 32. It is thus easy to see the differences in size that can be have between the different kinds of tabs.

Les figures 6C et 6D représentent le système de fixation dans le cas d'une lampe D1, lorsque le système est verrouillé. On comprend, en regardant les figures 6C et 6D par comparaison avec les figures 6A et 6B que, lorsque la bague rigide est dans la position déverrouillée, les premiers et le second ergots de la bague n'appuient sur aucune languette. Par contre, lorsque l'on fait subir une rotation de la bague rigide, d'environ 40°, par rapport à l'anneau flexible, les premiers ergots 22 viennent se placer devant les languettes de maintien 32 et le second ergot 28 devant la languette de positionnement 38. Le placement de ces ergots peut se faire de façon ordonnée, c'est-à-dire que le second ergot 28 se place avant les premiers ergots 22. Cette rotation de la bague rigide a pour conséquence de pousser les languettes de maintien vers le pied d'ampoule, rendant l'anneau flexible totalement circulaire. Cela a aussi pour conséquence de pousser la languette de positionnement au fond de son logement 39, lui permettant d'exercer une pression plaquant la lampe D1 dans le logement en V.Figures 6C and 6D show the fastening system in the case of a D1 lamp, when the system is locked. We understand, in looking at FIGS. 6C and 6D in comparison with FIGS. 6A and 6B that when the rigid ring is in the unlocked position, the first and the second lugs of the ring do not press on any tongue. On the other hand, when the rigid ring is rotated about 40 °, by compared to the flexible ring, the first lugs 22 come to stand before the holding tongues 32 and the second lug 28 in front of the tongue of positioning 38. The placement of these pins can be done ordinate, that is to say that the second lug 28 is placed before the first 22. This rotation of the rigid ring has the effect of pushing holding tabs towards the bulb foot, making the ring flexible totally circular. This also has the effect of pushing the tongue positioned at the bottom of his dwelling 39, allowing him to exercise pressing the lamp D1 in the housing in V.

La bague rigide 21 agit ainsi comme une came sur l'anneau flexible 31.The rigid ring 21 thus acts as a cam on the flexible ring 31.

Les figures 7A et 7C représentent des vues de coté, en coupe, du système de fixation de l'invention, dans le cas d'une lampe D2, lorsque le système est, respectivement, déverrouillé et verrouillé. Les figures 7B et 7D représentent des vues de dessus du système de fixation de l'invention, dans le cas d'une lampe D2, lorsque le système est, respectivement, déverrouillé et verrouillé. Les figures 7A et 7B montrent la position de la bague rigide 21 et de l'anneau flexible lorsque le système est déverrouillé. En particulier, elles montrent la position des premiers ergots 22a, 22b, 22c de la bague rigide par rapport aux languettes de maintien 32a, 32b, 32c de l'anneau flexible. Ces figures montrent également la position du second ergot 28 par rapport à la languettes de positionnement 38 de l'anneau flexible 31. En position déverrouillée, la languette de positionnement 38 est logée dans un logement du pied d'ampoule, mais elle est en biais dans ce logement.. Le verrouillage du système permet à cette languette d'exercer une poussée radiale sur la lampe afin de pousser la lampe au fond du logement en forme de V de la contrepartie. Ce logement en V est représenté sur la figure 7B par deux méplats 40 situés, radialement, à l'opposé du logement 39 recevant la languette de positionnement 38. Ces figures 7A et 7B montrent aussi le positionnement des languettes de contact 33, entre les languettes de maintien 32. On peut ainsi voir aisément les différences de taille qu'il peut y avoir entre les différentes sortes de languettes.FIGS. 7A and 7C show side views, in section, of the fixation system of the invention, in the case of a lamp D2, when the system is, respectively, unlocked and locked. Figures 7B and 7D represent top views of the fastening system of the invention, in the case of a lamp D2, when the system is, respectively, unlocked and locked. Figures 7A and 7B show the position of the rigid ring 21 and the flexible ring when the system is unlocked. In particular, they show the position of the first lugs 22a, 22b, 22c of the ring rigid relative to the retaining tabs 32a, 32b, 32c of the ring flexible. These figures also show the position of the second lug 28 by relative to the positioning tabs 38 of the flexible ring 31. In unlocked position, the positioning tongue 38 is housed in a housing the bulb foot, but it is angled in this housing .. The locking the system allows this tab to exert a push radial on the lamp to push the lamp to the bottom of the housing fit V's counterparty. This V-shaped housing is represented in FIG. 7B by two flats 40 located, radially, opposite the housing 39 receiving the positioning tab 38. These FIGS. 7A and 7B also show the positioning of the contact tabs 33, between the tabs of 32. It is thus easy to see the differences in size that can be have between the different kinds of tabs.

Les figures 7C et 7D représentent le système de fixation dans le cas d'une lampe D2, lorsque le système est verrouillé. On comprend, en regardant ces figures 7C et 7D par comparaison avec les figures 7A et 7B que, lorsque la bague rigide est dans la position déverrouillée, les premiers et le second ergots de la bague n'appuient sur aucune languette. Par contre, lorsque l'on fait subir une rotation de la bague rigide, d'environ 40°, par rapport à l'anneau flexible, les premiers ergots 22 viennent se placer devant les languettes de maintien 32 et le second ergot 28 devant la languette de positionnement 38. Le placement de ces ergots peut se faire de façon ordonnée, c'est-à-dire que le second ergot 28 se place avant les premiers ergots 22. Cette rotation de la bague rigide a pour conséquence de pousser les languettes de maintien vers le pied d'ampoule, rendant l'anneau flexible totalement circulaire. Cela a aussi pour conséquence de pousser la languette de positionnement au fond de son logement 39, lui permettant d'exercer une pression plaquant la lampe D2 dans le logement en V.Figures 7C and 7D show the fastening system in the case a D2 lamp, when the system is locked. We understand, in looking at these Figures 7C and 7D in comparison with Figures 7A and 7B that when the rigid ring is in the unlocked position, the first and the second lugs of the ring do not press on any tongue. On the other hand, when the rigid ring is rotated about 40 °, by compared to the flexible ring, the first lugs 22 come to stand before the holding tongues 32 and the second lug 28 in front of the tongue of positioning 38. The placement of these pins can be done ordinate, that is to say that the second lug 28 is placed before the first 22. This rotation of the rigid ring has the effect of pushing holding tabs towards the bulb foot, making the ring flexible totally circular. This also has the effect of pushing the tongue positioned at the bottom of his dwelling 39, allowing him to exercise pressing the lamp D2 in the housing in V.

On comprend alors que, après verrouillage du système, l'anneau flexible 31 assure la tenue mécanique et le positionnement d'une lampe D1 ou D2 sur la contrepartie, ainsi que la continuité électrique et le blindage électromagnétique entre la contrepartie et le module haute tension. Avant verrouillage, il fait fonction de pré-maintien de la lampe car le diamètre intérieur du cercle sur lequel sont réparties les languettes de maintien, en position déverrouillée, est inférieur au diamètre extérieur du culot de la lampe.We then understand that, after locking the system, the ring flexible 31 ensures the mechanical strength and positioning of a D1 lamp or D2 on the counterpart, as well as electrical continuity and shielding electromagnetic between the counterpart and the high voltage module. Before locking, it acts as a pre-hold of the lamp because the diameter inside the circle on which are distributed the holding tabs, in unlocked position, is less than the outside diameter of the base of the lamp.

On comprend aussi, d'après la description précédente, que le système est identique pour une lampe D1 et pour une lampe D2, seule la longueur des languettes de contact pouvant être différente. Les languettes de contact peuvent aussi être choisies de façon à avoir un profil similaire pour D1 et pour D2, ce qui permet de simplifier encore la fabrication du système.It is also understood from the previous description that the system is identical for a D1 lamp and for a D2 lamp, only the length contact tabs may be different. Contact tabs can also be chosen to have a similar profile for D1 and for D2, which further simplifies the manufacturing of the system.

De cette façon, le projecteur est standard pour une lampe D1 et pour une lampe D2. Il peut donc être réalisé en grande série, en production, et c'est simplement au moment de l'installation de la source lumineuse que l'on choisit, si besoin est, de prendre un anneau flexible à grandes languettes de contact, pour une lampe D2, ou à petites languettes de contact, pour une lampe D1. On peut ainsi monter une lampe D1 ou une lampe D2, au choix, en fonction du coût et de la disponibilité de l'une ou l'autre des lampes.In this way, the projector is standard for a D1 lamp and for a D2 lamp. It can therefore be produced in mass production, in production, and it is simply at the moment of the installation of the light source that one choose, if necessary, to take a flexible ring with large tabs of contact, for a lamp D2, or with small tongues of contact, for a D1 lamp. It is thus possible to mount a lamp D1 or a lamp D2, as desired, depending on the cost and availability of either lamp.
