Definitions
- the invention relates to a motor vehicle headlight, comprising a front optic and a mask that jointly delimit a housing, a lens located inside the housing, a source generating light, a reflector that reflects the light coming from the source to the lens, a cache substantially surrounding a space between the reflector and the lens.
- the reflector, the source and the lens are generally part of a set called elliptical module, which is attached to the housing, and which generates a lighting beam illuminating the road through the lens and the front optics of the lighthouse.
- the elliptical module is generally concealed behind the mask, so that only the lens is visible through the optics.
- the mask comprises for example a substantially tubular protuberance extending towards the optics, to surround a front portion of the elliptical module.
- the light from the source and the reflector is transmitted to the lens by the tubular protuberance of the mask.
- the cooling is ensured by natural convection, thanks to openings made in a rear part of the module that leaves the mask, through which fresh air is admitted into the module.
- the module is mounted in such a way that it passes through the mask which then has no protuberance, but only an opening in which this module is placed.
- the lens is then placed in front of the mask, and module armatures are at least partially visible through the optics of the headlight.
- the structure of the module comprises, for example, three claws starting from the reflector, each having an end which holds the lens in position, screwed to screw of the reflector. But other structures are also used.
- the cover does not cover all the space between the reflector and the lens, but instead includes large openings that allow air to circulate between the space between the lens and the source, and the rest of the lighthouse.
- Ventilation openings which favor a natural convection movement have, in a known headlight, a longitudinal slot shape, so that the cache has a general shape corresponding to several petals inscribed in the same cylinder, two consecutive petals along the cylinder being separated by a ventilation slot.
- the module comprises a cover which is provided with fins oriented so as to allow cooling by circulating air between the inside of the cover and the inside of the headlight housing.
- the object of the invention is to provide a lighthouse structure that overcomes this disadvantage.
- the subject of the invention is a motor vehicle headlight, as defined in claim 1 .
- the invention also relates to a lighthouse as defined in the dependent claims.
- an elliptical module 1 of a headlight comprises a source 2 a reflector 3 and a lens 4.
- the reflector 3 which may be elliptical is positioned opposite the lens 4, such that the light generated by the source 2 is reflected by this reflector towards the lens 4.
- This reflector 3 surrounding the source 2 is not sufficient to ensure that all of the light emitted by the source 2 is actually directed towards the lens 4.
- the light rays reflected by the reflector 3 are directed towards the lens, but the light rays generated by the source 2 towards the front of the elliptical module are oriented in all directions. The latter can therefore be emitted laterally, and thus constitute a source. important blindness, particularly troublesome for the driver of another vehicle passing near this lighthouse.
- this cover may have for example a form of revolution, which is here a cylinder whose diameter corresponds to that of the periphery of the reflector 3, and that of the periphery of the lens 4.
- This cooling is also ensured by the convection of the air circulating in the housing of the lighthouse around the module 1, this interior air of the headlamp being itself cooled by the optics of this lighthouse. Finally, this cooling is still provided by unrepresented openings, located in the rear part, through which air flows from outside the housing, by natural convection.
- This elliptical module which correctly transmits the light to the lens, thanks to its cover 7, however, is not satisfactory from the point of view of cooling.
- the need to provide in particular cooling openings in its rear portion limits its implantation possibilities.
- the cover marked by 7 comprises gills 10, 11 and 12 made in its wall, which are oriented to let air, while interrupting the light beams directed from the source to these gills.
- a natural convection, marked by 14, is thus provided between the interior space 5 of the elliptical module and the space in the headlight housing, which significantly improves the cooling of the source 2.
- gills 10, 11 and 12 may be located in different areas of the cover 7, but they are advantageously located in a part near the source 2 which is the source of heat to be cooled.
- the cover 7 comprises a base 15 which is extended by a tube 16.
- the base 15 has an end secured to the reflector 3 and its other end which is extended by the tube 16.
- This tube 16 thus has an end secured to the base 15 and its other end secured to the lens 4.
- the base 15 is thus closest to the source 2 which it surrounds while the tube 16 is closer to the lens 4 it maintains.
- the base 15 can thus be formed by a completely opaque material to block all light rays directed laterally by the source, to avoid blinding a vehicle placed laterally with respect to the headlight, and the tube 16 can be only partially opaque so that the lighthouse is visible laterally without being blinding.
- the base can thus be made of a metallic material, which furthermore makes it possible to further promote cooling by thermal radiation of the base in the headlight.
- the gills made in the wall of the cover 7 and marked by 10, 11 and 12 can be of any suitable form, as long as they block the light rays from the source 2 while allowing air to pass.
- each ear has an annular shape which defines an opening directed towards the mask to let air pass.
- Each ear has a general shape substantially of truncated cone the front end has a smaller diameter than the rear end.
- each ear viewed in section along a plane comprising the longitudinal axis of the module, has a substantially curved section, between its small diameter and its large diameter, designed to further promote the flow of air due to natural convection.
- These gills are here identical to each other being placed one behind the other.
- the hearing 12 which is closest to the reflector 3 is positioned in a plane which corresponds to the plane of the mask 17 of the headlight, so that it can thus define an opening which opens through the mask 17, as in FIG. the example of Figures 2 and 4 .
- This hearing thus communicates the interior of the elliptical module with the outside air, which further contributes to promoting the cooling of the elliptical module by introducing fresh air therein.
- the hearing 12 may also be provided closed by the reflector, as in the example of the figure 3 .
- the gills which are shown in the examples of the figures all have substantially identical diameters, but these diameters may also differ from one hearing to another.
- the cooling of the module and the cooling of the headlight in general are further improved by the possibility of fresh air entering the elliptical module, but also by the possibility for this fresh air to renew the air present in the space interior of the lighthouse, because the inner space 5 of the elliptical module communicates through gills 10 and 11 with the interior space of the housing constituting the lighthouse.
- the lens 3 can be maintained directly by the cover 7, which avoids resorting to a holding structure, such as the three-claw structures known from the state of the art.
- the elliptical module can thus have an outer shape of revolution, as visible in the front view of the figure 5 , which facilitates its implementation in different types of lighthouses.

Abstract
Description
L'invention concerne un phare de véhicule automobile, comprenant une optique frontale et un masque qui délimitent conjointement un boîtier, une lentille située à l'intérieur de ce boîtier, une source générant de la lumière, un réflecteur qui réfléchit la lumière issue de la source vers la lentille, un cache entourant sensiblement un espace situé entre le réflecteur et la lentille.The invention relates to a motor vehicle headlight, comprising a front optic and a mask that jointly delimit a housing, a lens located inside the housing, a source generating light, a reflector that reflects the light coming from the source to the lens, a cache substantially surrounding a space between the reflector and the lens.
Dans un tel phare, le réflecteur, la source et la lentille font généralement partie d'un ensemble appelé module elliptique, qui est fixé au boîtier, et qui génère un faisceau d'éclairage illuminant la route à travers la lentille et l'optique frontale du phare.In such a lighthouse, the reflector, the source and the lens are generally part of a set called elliptical module, which is attached to the housing, and which generates a lighting beam illuminating the road through the lens and the front optics of the lighthouse.
Dans les phares actuels, le module elliptique est généralement dissimulé derrière le masque, de telle sorte que seule la lentille est visible, à travers l'optique. Le masque comprend par exemple une protubérance sensiblement tubulaire s'étendant en direction de l'optique, pour entourer une partie avant du module elliptique.In current headlights, the elliptical module is generally concealed behind the mask, so that only the lens is visible through the optics. The mask comprises for example a substantially tubular protuberance extending towards the optics, to surround a front portion of the elliptical module.
La lumière issue de la source et du réflecteur est transmise vers la lentille par la protubérance tubulaire du masque. Le refroidissement est assuré par convection naturelle, grâce à des ouvertures réalisées dans une partie arrière du module qui sort du masque, par lesquelles de l'air frais est admis dans le module.The light from the source and the reflector is transmitted to the lens by the tubular protuberance of the mask. The cooling is ensured by natural convection, thanks to openings made in a rear part of the module that leaves the mask, through which fresh air is admitted into the module.
Dans une évolution plus récente, le module est monté de telle manière qu'il traverse le masque qui ne comporte alors pas de protubérance, mais seulement une ouverture dans laquelle est placé ce module. La lentille est alors placée en avant du masque, et des éléments d'armature du module sont au moins partiellement visibles à travers l'optique du phare.In a more recent evolution, the module is mounted in such a way that it passes through the mask which then has no protuberance, but only an opening in which this module is placed. The lens is then placed in front of the mask, and module armatures are at least partially visible through the optics of the headlight.
La structure du module comprend par exemple trois griffes partant du réflecteur, ayant chacune une extrémité qui maintient la lentille en position, en vis à vis du réflecteur. Mais d'autres structures sont également utilisées.The structure of the module comprises, for example, three claws starting from the reflector, each having an end which holds the lens in position, screwed to screw of the reflector. But other structures are also used.
Il est nécessaire de prévoir un cache qui entoure, au moins partiellement, l'espace situé entre le réflecteur et la lentille, pour transmettre la lumière vers la lentille. Ce cache interrompt la lumière émise selon une direction latérale car celle-ci constitue une perte importante d'éclairage, et aussi une source d'aveuglement gênante pour les conducteurs d'autres véhicules.It is necessary to provide a cover that surrounds, at least partially, the space between the reflector and the lens, to transmit the light to the lens. This cache interrupts the light emitted in a lateral direction because it is a significant loss of lighting, and also a source of annoying blindness for drivers of other vehicles.
Compte tenu de la chaleur que génère la source, le cache ne recouvre pas tout l'espace situé entre le réflecteur et la lentille, mais il comprend au contraire des ouvertures importantes qui autorisent une circulation d'air entre l'espace situé entre la lentille et la source, et le reste du phare.Given the heat generated by the source, the cover does not cover all the space between the reflector and the lens, but instead includes large openings that allow air to circulate between the space between the lens and the source, and the rest of the lighthouse.
Ces ouvertures d'aération qui favorisent un mouvement de convection naturelle ont, dans un phare connu, une forme de fente longitudinale, de sorte que le cache a une forme générale correspondant à plusieurs pétales inscrits dans un même cylindre, deux pétales consécutifs le long du cylindre étant séparés par une fente d'aération.These ventilation openings which favor a natural convection movement have, in a known headlight, a longitudinal slot shape, so that the cache has a general shape corresponding to several petals inscribed in the same cylinder, two consecutive petals along the cylinder being separated by a ventilation slot.
La chaleur générée par la source étant importante, ces ouvertures doivent avoir de grandes dimensions, mais elles laissent par conséquent passer de la lumière latéralement. Cette lumière latérale est préjudiciable à l'efficacité du projecteur et elle constitue une source d'éblouissement latéral pour les conducteurs d'autres véhicules.The heat generated by the source being important, these openings must have large dimensions, but they therefore allow light to pass laterally. This side light is detrimental to the efficiency of the headlamp and is a source of side glare for drivers of other vehicles.
Il est également connu une structure de module elliptique incluant un cache de très faibles dimensions qui entoure seulement la source sur une courte longueur.There is also known an elliptical module structure including a very small cache that surrounds only the source for a short length.
Mais cette autre solution qui favorise le refroidissement du module et de la source n'est pas satisfaisante du point de vue de l'éclairage. En effet, le cache de faible longueur qui entoure la source n'est pas suffisant pour interrompre efficacement la lumière qui est dirigée latéralement.But this other solution that promotes the cooling of the module and the source is not satisfactory from the point of view of lighting. Indeed, the short cache that surrounds the source is not enough to effectively interrupt the light that is directed laterally.
Il existe encore des modules elliptiques dont la partie avant est entièrement fermée par un cache, et dont la partie arrière est ouverte de manière à favoriser l'admission d'air frais dans le module. Cependant, le refroidissement ainsi obtenu est insuffisant pour permettre une utilisation avec tous types de sources.There are still elliptical modules whose front part is completely closed by a cover, and whose rear part is open to promote the admission of fresh air into the module. However, the resulting cooling is insufficient to allow use with all types of sources.
Dans un phare connu du document de brevetIn a known lighthouse of the patent document
Ces ailettes sont orientées pour interrompre la lumière issue de la source, cependant, ces ailettes ne permettent pas de refroidir suffisamment le phare.These fins are oriented to interrupt the light from the source, however, these fins do not sufficiently cool the lighthouse.
Le but de l'invention est de proposer une structure de phare qui remédie à cet inconvénient.The object of the invention is to provide a lighthouse structure that overcomes this disadvantage.
A cet effet, l'invention a pour objet un phare de véhicule automobile, tel que défini dans la revendication 1.For this purpose, the subject of the invention is a motor vehicle headlight, as defined in
L'invention a également pour objet un phare tel que défini dans les revendications dépendantes.The invention also relates to a lighthouse as defined in the dependent claims.
L'invention sera maintenant décrite plus en détail, et en référence aux dessins annexés qui en illustrent une forme de réalisation à titre d'exemple non limitatif.

figure 3 est une vue en coupe d'une variante du module de lafigure 2 ; - La

figure 5 est une vue de face du module elliptique du phare de lafigure 1 .
- The

figure 2 is a sectional view showing an elliptical module of the headlight according to the invention; - The
figure 3 is a sectional view of a variant of the module of thefigure 2 ; - The
figure 4 is a profile view of the elliptical module of the headlight according to the invention; - The
figure 5 is a front view of the elliptical module of the lighthouse of thefigure 1 .
Ce réflecteur 3 qui entoure la source 2 n'est cependant pas suffisant pour assurer que la totalité de la lumière émise par la source 2 est effectivement dirigée vers la lentille 4.This
En effet, les rayons lumineux réfléchis par le réflecteur 3 sont dirigés vers la lentille, mais les rayons lumineux générés par la source 2 vers l'avant du module elliptique sont orientés dans toutes les directions. Ces derniers peuvent par conséquent être émis latéralement, et constituer ainsi une source. d'aveuglement importante, gênante notamment pour le conducteur d'un autre véhicule passant à proximité de ce phare.Indeed, the light rays reflected by the
C'est ainsi qu'il est nécessaire de prévoir, en plus du réflecteur 3, une structure de cache qui entoure l'espace 5 qui est situé entre le réflecteur 3 et la lentille 4. Comme visible sur la figure, ce cache peut avoir par exemple une forme de révolution, qui est ici un cylindre dont le diamètre correspond à celui du pourtour du réflecteur 3, et à celui du pourtour de la lentille 4.Thus it is necessary to provide, in addition to the
Dans ce module elliptique qui est connu de l'état de la technique, le refroidissement de la source 2 est assuré par la convection naturelle de l'air emprisonné dans l'espace 5 situé entre le réflecteur 3 et la lentille 4, ce qui est représenté schématiquement par les flèches repérées par 9.In this elliptical module which is known from the state of the art, the cooling of the
Ce refroidissement est aussi assuré par la convection de l'air circulant dans le boîtier du phare autour du module 1, cet air intérieur du phare étant lui-même refroidi par l'optique de ce phare. Enfin, ce refroidissement est encore assuré par des ouvertures non représentées, situées en partie arrière, par lesquelles circule de l'air en provenance de l'extérieur du boîtier, par convection naturelle.This cooling is also ensured by the convection of the air circulating in the housing of the lighthouse around the
Ce module elliptique qui transmet correctement la lumière vers la lentille, grâce à son cache 7, n'est cependant pas satisfaisant du point de vue du refroidissement. De plus, la nécessité de prévoir notamment des ouvertures de refroidissement dans sa partie arrière limite ses possibilités d'implantation.This elliptical module which correctly transmits the light to the lens, thanks to its cover 7, however, is not satisfactory from the point of view of cooling. In addition, the need to provide in particular cooling openings in its rear portion limits its implantation possibilities.
Selon l'invention, le cache repéré par 7 comprend des ouïes 10, 11 et 12 réalisées dans sa paroi, qui sont orientées pour laisser passer de l'air, tout en interrompant les faisceaux lumineux dirigés depuis la source vers ces ouïes.According to the invention, the cover marked by 7 comprises
Une convection naturelle, repérée par 14, est ainsi assurée entre l'espace intérieur 5 du module elliptique et l'espace situé dans le boîtier du phare, ce qui améliore significativement le refroidissement de la source 2.A natural convection, marked by 14, is thus provided between the
Ces ouïes 10, 11 et 12 peuvent être situées dans différentes zones du cache 7, mais elles sont, avantageusement situées dans une partie proche de la source 2 qui constitue la source de chaleur à refroidir.These
Avantageusement, comme dans les
L'embase 15 est ainsi la plus proche de la source 2 qu'elle entoure alors que le tube 16 est lui plus proche de la lentille 4 qu'il maintient. L'embase 15 peut ainsi être formée par un matériau complètement opaque pour bloquer tous les rayons lumineux dirigés latéralement par la source, afin d'éviter d'aveugler un véhicule placé latéralement par rapport au phare, et le tube 16 peut être seulement partiellement opaque de telle sorte que le phare soit visible latéralement sans être aveuglant.The
L'embase peut ainsi être fabriquée dans un matériau métallique, ce qui permet, en outre de favoriser encore le refroidissement par rayonnement thermique de l'embase dans le phare.The base can thus be made of a metallic material, which furthermore makes it possible to further promote cooling by thermal radiation of the base in the headlight.
Les ouïes réalisées dans la paroi du cache 7 et repérées par 10, 11 et 12 peuvent être de toute forme appropriée, pour autant qu'elles bloquent les rayons lumineux issus de la source 2 tout en laissant passer de l'air.The gills made in the wall of the cover 7 and marked by 10, 11 and 12 can be of any suitable form, as long as they block the light rays from the
Dans l'exemple des figures chaque ouïe a une forme annulaire qui définit une ouverture orientée vers le masque pour laisser passer de l'air. Chaque ouïe a une forme générale sensiblement de tronc de cône dont l'extrémité avant a un diamètre plus faible que l'extrémité arrière.In the example of the figures, each ear has an annular shape which defines an opening directed towards the mask to let air pass. Each ear has a general shape substantially of truncated cone the front end has a smaller diameter than the rear end.
Plus particulièrement, chaque ouïe vue en coupe selon un plan comprenant l'axe longitudinal du module, a une section sensiblement courbe, entre son petit diamètre et son grand diamètre, conçue pour favoriser encore l'écoulement d'air dû à la convection naturelle. Ces ouïes sont ici identiques les unes aux autres en étant placées les unes derrière les autres.More particularly, each ear viewed in section along a plane comprising the longitudinal axis of the module, has a substantially curved section, between its small diameter and its large diameter, designed to further promote the flow of air due to natural convection. These gills are here identical to each other being placed one behind the other.
Avantageusement, l'ouïe 12 qui est la plus proche du réflecteur 3 est positionnée dans un plan qui correspond au plan du masque 17 du phare, de telle sorte qu'elle peut ainsi définir une ouverture qui débouche à travers le masque 17, comme dans l'exemple des
L'ouïe 12 peut également être prévue fermée par le réflecteur, comme dans l'exemple de la
Ainsi, le refroidissement du module et le refroidissement du phare en général sont encore améliorés par la possibilité d'entrée d'air frais dans le module elliptique, mais aussi par la possibilité pour cet air frais de renouveler l'air présent dans l'espace intérieur du phare, car l'espace intérieur 5 du module elliptique communique grâce aux ouïes 10 et 11 avec l'espace intérieur du boîtier constituant le phare.Thus, the cooling of the module and the cooling of the headlight in general are further improved by the possibility of fresh air entering the elliptical module, but also by the possibility for this fresh air to renew the air present in the space interior of the lighthouse, because the
La lentille 3 peut être maintenue directement par le cache 7, ce qui évite de recourir à une structure de maintien, telle que les structures à trois griffes connues de l'Etat de la technique. Le module elliptique peut ainsi avoir une forme extérieure de révolution, comme visible dans la vue de face de la
