Description

La présente invention a pour objet un kit pour la réalisation d'un luminaire destiné plus particulièrement, mais pas exclusivement, à l'éclairage public, et qui soit adapté aussi bien aux zones urbaines ou périurbaines qu'aux zones rurales ou à tout autre endroit nécessitant un tel éclairage.The present invention relates to a kit for producing a luminaire intended more particularly, but not exclusively, for public lighting, and which is suitable both for urban or peri-urban areas as well as for rural areas or any other location requiring such lighting.

En fait, la présente invention entend apporter une réponse universelle aux problématiques qui se posent actuellement tant sur le plan technique qu'esthétique dans la réalisation de luminaires de bonne facture.In fact, the present invention aims to provide a universal response to the problems that currently arise both on a technical and aesthetic level in the production of high-quality lighting fixtures.

A cet effet, l'invention a pour objectif principal de fournir une solution basée sur la technologie des lampes à diodes électroluminescentes (ou « lampes à LED »), solution dont la mise en oeuvre repose sur l'assemblage de quelques éléments de structure très simple et compacte conçus de manière à présenter un caractère standard, permettant de proposer une gamme de luminaires adaptés à une multiplicité de configurations, offrant une possibilité de design infinie, ainsi que des performances diverses, améliorées par rapport aux dispositifs classiques en termes de longévité, de consommation énergétique et de qualité d'éclairage.To this end, the main objective of the invention is to provide a solution based on the technology of light-emitting diode lamps (or "LED lamps"), a solution whose implementation is based on the assembly of a few elements of very simple and compact structure designed to have a standard character, making it possible to offer a range of luminaires adapted to a multiplicity of configurations, offering an infinite design possibility, as well as various performances, improved compared to conventional devices in terms of longevity, energy consumption and lighting quality.

Un autre objectif de la présente invention est encore de proposer une solution permettant de générer un éclairage uniforme, permettant au public de repérer d'éventuels obstacles et changements de direction tout en limitant les éventuels phénomènes d'éblouissement sources d'inconfort, voire de mise en danger notamment de piétons ou d'usagers d'une chaussée.Another objective of the present invention is to propose a solution for generating uniform lighting, allowing the public to identify possible obstacles and changes in direction while limiting possible glare phenomena which are sources of discomfort, or even danger, in particular for pedestrians or road users.

En d'autres termes, le présent demandeur a imaginé une solution dans laquelle les fonctions d'éclairage et d'aspect esthétique d'un luminaire peuvent pratiquement être assurées par son optique LED à elle seule à part entière, qui est rendue autonome et présente des fonctions plurielles, et ne nécessite pour son installation qu'un support sur lequel l'accrocher au moyen d'un organe de solidarisation, ces deux derniers pouvant le cas échéant également contribuer à conférer au luminaire le design final recherché. Dans la présente invention et conformément à ce qui est détaillé dans la norme EN 60598-1.2.1 « un luminaire est un appareil qui répartit, filtre ou transforme la lumière émise par une ou plusieurs lampes et qui comporte non les lampes elles-mêmes, mais toutes les pièces nécessaires pour le support, la fixation et la protection des lampes et, si nécessaire, les circuits auxiliaires et les moyens de branchement de ceux-ci au réseau d'alimentation » ; ainsi un luminaire implique l'utilisation de lampes mais n'est pas une lampe.In other words, the present applicant has imagined a solution in which the lighting and aesthetic appearance functions of a luminaire can practically be ensured by its LED optic alone in its own right, which is made autonomous and has multiple functions, and requires for its installation only a support on which to hang it by means of a securing member, the latter two being able, if necessary, also to contribute to giving the luminaire the desired final design. In the present invention and in accordance with this which is detailed in the standard EN 60598-1.2.1 "a luminaire is a device which distributes, filters or transforms the light emitted by one or more lamps and which includes not the lamps themselves, but all the parts necessary for the support, fixing and protection of the lamps and, if necessary, the auxiliary circuits and the means of connecting them to the supply network"; thus a luminaire involves the use of lamps but is not a lamp.

À cet effet, l'invention a pour objet un kit pour la réalisation d'un luminaire selon la revendication 1, ledit kit comprenant :

  • un boîtier de forme plate et de surface plane, intégrant l'ensemble des moyens optiques, électroniques et électriques du luminaire (1) dont au moins une face est au moins partiellement vitrée, hébergeant au moins une carte de circuit imprimé sur laquelle est montée au moins une diode électroluminescente orientée en direction de la face au moins partiellement vitrée,
  • un support pour accrocher ledit boîtier au-dessus d'une zone à éclairer, et
  • un organe de solidarisation du boîtier audit support, comportant au moins un logement conçu apte à loger au moins une partie du boîtier, et un embout permettant la fixation du logement audit support. Une fois les éléments constituant le kit sélectionnés par le client, lesdits éléments vont être usinés afin de livrer un luminaire complet prêt à poser. Ce kit permet donc de proposer une gamme très vaste de luminaires ayant en commun un boîtier, un support et un organe de solidarisation tels que décrits ci-dessus.
For this purpose, the invention relates to a kit for producing a luminaire according to claim 1, said kit comprising:
  • a flat-shaped housing with a flat surface, integrating all the optical, electronic and electrical means of the luminaire (1) of which at least one face is at least partially glazed, housing at least one printed circuit board on which is mounted at least one light-emitting diode oriented towards the at least partially glazed face,
  • a support for hanging said housing above an area to be illuminated, and
  • a body for securing the housing to said support, comprising at least one housing designed to accommodate at least part of the housing, and an end piece enabling the housing to be secured to said support. Once the elements constituting the kit have been selected by the customer, said elements will be machined in order to deliver a complete luminaire ready to install. This kit therefore makes it possible to offer a very wide range of luminaires having in common a housing, a support and a securing body as described above.

Conformément à une variante de réalisation envisageable du kit selon l'invention, l'organe de solidarisation comporte une articulation reliant ledit logement et ledit embout.In accordance with a possible variant embodiment of the kit according to the invention, the securing member comprises a joint connecting said housing and said end piece.

Par ailleurs, il a également été imaginé que dans certains cas, ledit organe de solidarisation peut comporter une carrosserie conçue apte à habiller au moins partiellement ledit boîtier. C'est cette carrosserie qui peut notamment influer sur l'apparence générale du luminaire.Furthermore, it has also been imagined that in certain cases, said securing member may comprise a body designed to at least partially cover said housing. It is this body which may in particular influence the general appearance of the luminaire.

Selon l'invention, le boîtier est conçu de manière à comporter un fond surmonté par une paroi périphérique délimitant un espace de forme et de dimension ajustées en fonction du nombre de cartes de circuit imprimé hébergées par ledit boîtier, ledit espace étant fermé par ladite face au moins partiellement vitrée.According to the invention, the housing is designed so as to comprise a bottom surmounted by a peripheral wall delimiting a space of shape and dimension adjusted according to the number of printed circuit cards housed by said housing, said space being closed by said at least partially glazed face.

Il est également avantageusement prévu que ledit boîtier comporte des moyens aptes à dissiper la chaleur émise par ladite diode électroluminescente, et qui peuvent notamment être définis par le fond et la paroi périphérique du boîtier réalisés en un matériau conducteur thermique choisi parmi le groupe comprenant l'aluminium, un alliage d'aluminium, un acier, un matériau composite. Ces moyens aptes à dissiper la chaleur n'influent aucunement sur le fait que le boîtier soit de forme plate et de surface externe plane.It is also advantageously provided that said housing comprises means capable of dissipating the heat emitted by said light-emitting diode, and which may in particular be defined by the bottom and the peripheral wall of the housing made of a thermally conductive material chosen from the group comprising aluminum, an aluminum alloy, a steel, a composite material. These means capable of dissipating heat have no influence on the fact that the housing is flat in shape and has a flat external surface.

En référence aux figures, la présente invention concerne un kit pour la réalisation d'un luminaire 1 se composant de différents éléments structurels, qui sont avantageusement disponibles chacun sous forme de gamme, et qui peuvent par conséquent être spécifiquement sélectionnés pour correspondre aux besoins exprimés aussi bien en termes d'éclairage que d'aspect esthétique final du luminaire 1.With reference to the figures, the present invention relates to a kit for producing a luminaire 1 consisting of different structural elements, which are advantageously each available in the form of a range, and which can consequently be specifically selected to correspond to the needs expressed both in terms of lighting and of the final aesthetic appearance of the luminaire 1.

En particulier, le kit selon l'invention comporte en tant qu'élément structurel de base, un boîtier 2 intégrant l'ensemble des moyens optiques, électroniques et électriques du luminaire 1 et assurant par conséquent à lui seul au moins la fonction d'éclairage de ce dernier. En effet, comme on le verra plus en détails ci-après, le boîtier 2 peut également déterminer à lui seul l'aspect esthétique final du luminaire 1. Les figures 3-5 détaillent un boîtier 2 selon l'invention qui est plat et de surface externe plane. Cette forme plate et cette surface externe plane sont nécessaires à cet élément structurel de base pour permettre la modularité proposée par le kit selon l'invention. On voit notamment en figure 3 la forme plate du boîtier 2 avec ses surfaces nommées fond 3 et face vitrée 8 qui sont planes.In particular, the kit according to the invention comprises, as a basic structural element, a housing 2 integrating all the optical, electronic and electrical means of the luminaire 1 and consequently ensuring by itself at least the lighting function of the latter. Indeed, as will be seen in more detail below, the housing 2 can also determine by itself the final aesthetic appearance of the luminaire 1. Figures 3-5 detail a housing 2 according to the invention which is flat and has a flat external surface. This flat shape and this flat external surface are necessary for this basic structural element to allow the modularity proposed by the kit according to the invention. We see in particular in figure 3 the flat shape of the housing 2 with its surfaces named bottom 3 and glass face 8 which are flat.

Dans la variante de réalisation illustrée, le boîtier 2 présente une forme de pavé comportant un fond 3 surmonté par une paroi périphérique 4 délimitant un espace 5 conçu apte à loger quatre cartes de circuit imprimé 6 portant chacune une pluralité de diodes électroluminescentes 7. Bien entendu, le boîtier 2 pourrait également héberger un nombre différent de cartes de circuit imprimé 6 ou présenter une autre forme, par exemple celle d'un disque d'épaisseur appropriée, ou toute autre conforme aux attentes exprimées.In the illustrated embodiment variant, the housing 2 has the shape of a block comprising a bottom 3 surmounted by a peripheral wall 4 delimiting a space 5 designed to accommodate four printed circuit boards 6 each carrying a plurality of light-emitting diodes 7. Of course, the housing 2 could also accommodate a different number of printed circuit boards 6 or have another shape, for example that of a disk of appropriate thickness, or any other conforming to the expectations expressed.

Dans un mode de réalisation particulier de l'invention le boîtier 2 de forme plate présente une épaisseur totale de 10 cm, plus préférentiellement une épaisseur comprise entre 1 et 4 cm et encre plus préférentiellement une épaisseur comprise entre 2 et 3 cm. Dans un mode de réalisation préféré le boîtier 2 de forme plate a une épaisseur totale de 3 cm.In a particular embodiment of the invention, the flat-shaped housing 2 has a total thickness of 10 cm, more preferably a thickness of between 1 and 4 cm and more preferably a thickness of between 2 and 3 cm. In a preferred embodiment, the flat-shaped housing 2 has a total thickness of 3 cm.

Il convient de noter que la performance des diodes électroluminescentes 7 montées sur chacune des cartes de circuit imprimé 6, est améliorée par la présence de lentilles 70, de préférence interchangeables, qui permettent d'obtenir une distribution photométrique par réfraction du rayonnement lumineux bien supérieure en qualité à celle d'une distribution par réflexion obtenue au moyen de lampes à décharge classiques.It should be noted that the performance of the light-emitting diodes 7 mounted on each of the printed circuit boards 6 is improved by the presence of lenses 70, preferably interchangeable, which make it possible to obtain a photometric distribution by refraction of the light radiation much higher in quality than that of a distribution by reflection obtained by means of conventional discharge lamps.

D'autre part, en référence aux figures, l'espace 5 est recouvert par une face 8 comportant une zone vitrée 9, réalisée de préférence en verre trempé à haute résistance aux chocs ou en tout autre matériau à propriétés équivalentes, et apte à permettre le passage du rayonnement lumineux émis par les diodes électroluminescentes 7.On the other hand, with reference to the figures, the space 5 is covered by a face 8 comprising a glazed area 9, preferably made of high impact-resistant tempered glass or any other material with equivalent properties, and capable of allowing the passage of light radiation emitted by the light-emitting diodes 7.

A ce propos, il est prévu que la face vitrée 8 repose sur un épaulement 10, s'étendant entre la face interne 40 et le chant libre 41 de la paroi périphérique 4 du boîtier 2, et sur lequel elle est fixée, par exemple au moyen d'une colle de composition appropriée. Par ailleurs, l'étanchéité de l'espace 5 est assurée au moyen d'un joint, disposé entre la face vitrée 8 et l'épaulement 10, dans une gorge 11 que comporte ce dernier. Il est précisé que conformément à une variante de réalisation préférentielle, il peut être prévu que la colle utilisée pour fixer la face vitrée 8 sur l'épaulement 10 joue conjointement le rôle de joint d'étanchéité.In this regard, it is provided that the glazed face 8 rests on a shoulder 10, extending between the internal face 40 and the edge free 41 of the peripheral wall 4 of the housing 2, and on which it is fixed, for example by means of an adhesive of appropriate composition. Furthermore, the sealing of the space 5 is ensured by means of a seal, arranged between the glazed face 8 and the shoulder 10, in a groove 11 which the latter comprises. It is specified that in accordance with a preferred embodiment variant, it may be provided that the adhesive used to fix the glazed face 8 on the shoulder 10 jointly plays the role of a sealing gasket.

Conformément à l'invention, les cartes de circuit imprimé 6 sont avantageusement disposées dans l'espace 5 de manière telle qu'elles se situent au contact tant du fond 3 que de la paroi périphérique 4 du boîtier 2, qui sont avantageusement réalisés en un matériau conducteur thermique tel que par exemple de l'aluminium, un alliage d'aluminium, un acier, un matériau composite, ou en tout autre matériau présentant des propriétés équivalentes.According to the invention, the printed circuit boards 6 are advantageously arranged in the space 5 in such a way that they are in contact with both the bottom 3 and the peripheral wall 4 of the housing 2, which are advantageously made of a thermally conductive material such as, for example, aluminum, an aluminum alloy, steel, a composite material, or any other material having equivalent properties.

Grâce à une telle structure, les cartes de circuit imprimé 6 profitent de la masse du corps du boîtier 2 qui, faisant office de radiateur, se refroidit rapidement au contact de l'air extérieur. Le boîtier 2 en tant que tel permet ainsi de contrôler l'échauffement inhérent au fonctionnement des diodes électroluminescentes 7, et d'éviter que celles-ci ne soient soumises à des températures supérieures à environ 85°C. En effet, de manière connue, au-delà de ce seuil, l'intégrité des diodes électroluminescentes 7, et par conséquent leur longévité, est menacée.By means of such a structure, the printed circuit boards 6 benefit from the mass of the body of the housing 2 which, acting as a radiator, cools rapidly upon contact with the outside air. The housing 2 as such thus makes it possible to control the heating inherent in the operation of the light-emitting diodes 7, and to prevent them from being subjected to temperatures above approximately 85°C. Indeed, as is known, beyond this threshold, the integrity of the light-emitting diodes 7, and consequently their longevity, is threatened.

Conformément à une autre caractéristique de l'invention, dans la variante de réalisation illustrée, l'espace 5 est subdivisé, au moyen de trois barres 13 à section en « V », en quatre compartiments coplanaires 12, hébergeant chacun une carte de circuit imprimé 6. Les barres 13 présentent chacune deux flancs opposés 14a, 14b réunis par un sommet 15, et s'étendent le long du fond 3 du boîtier 2 de manière telle que leur sommet 15 est orienté en direction de la face vitrée 8 du boîtier 2.According to another characteristic of the invention, in the illustrated embodiment, the space 5 is subdivided, by means of three bars 13 with a “V” section, into four coplanar compartments 12, each housing a printed circuit card 6. The bars 13 each have two opposite sides 14a, 14b joined by a peak 15, and extend along the bottom 3 of the housing 2 in such a way that their peak 15 is oriented towards the glazed face 8 of the housing 2.

En fait, chacune des barres 13 est spécifiquement étudiée, structurée et disposée dans l'espace 5 de manière à définir une surface jouant le rôle d'un mur anti-éblouissement pour un usager de la zone dans laquelle le luminaire 1 est implanté. En d'autres termes, la présence des barres 13 permet de conférer d'excellentes performances en termes de confort au luminaire 1 présentant par ailleurs d'ores et déjà d'excellentes performances en termes d'éclairage au travers des lentilles 70.In fact, each of the bars 13 is specifically studied, structured and arranged in the space 5 so as to define a surface playing the role of an anti-glare wall for a user of the area in which the luminaire 1 is installed. In other words, the presence of the bars 13 makes it possible to confer excellent performance in terms of comfort on the luminaire 1, which already has excellent performance in terms of lighting through the lenses 70.

De plus, les barres 13 présentent l'avantage de définir chacune une surface d'échanges thermique supplémentaire, permettant de contribuer à la dissipation de l'échauffement induit par les diodes électroluminescentes 7 lorsqu'elles fonctionnent. En d'autres termes, la présence des barres 13 permet de réduire encore plus efficacement la chaleur dégagée par les cartes de circuit électronique 6 et par conséquent de contribuer à l'allongement de la longévité du luminaire 1.In addition, the bars 13 have the advantage of each defining an additional heat exchange surface, making it possible to contribute to the dissipation of the heating induced by the light-emitting diodes 7 when they operate. In other words, the presence of the bars 13 makes it possible to reduce even more effectively the heat released by the electronic circuit boards 6 and consequently to contribute to extending the life of the luminaire 1.

Dans un objectif similaire de préservation de l'intégrité du luminaire 1, et de suppression de toute opération de maintenance, comme notamment le remplacement des ampoules, la présente invention a également prévu que le volume disponible à l'intérieur du boîtier 2, en dehors de l'espace 5, est conçu apte à recevoir tous les organes électriques et électroniques nécessaires au fonctionnement pérenne des diodes électroluminescentes 7. A cet effet, le boîtier 2 renferme une cavité additionnelle 16 abritant, entre autres, des moyens de protection des cartes de circuit imprimé 6 contre les nuisances de courant électrostatique. La cavité 16 peut également renfermer un filtre thermique supplémentaire pour parer à des fonctionnements sous des températures inhabituelles.For a similar purpose of preserving the integrity of the luminaire 1, and eliminating any maintenance operation, such as in particular the replacement of the bulbs, the present invention has also provided that the volume available inside the housing 2, outside the space 5, is designed to accommodate all the electrical and electronic components necessary for the long-term operation of the light-emitting diodes 7. For this purpose, the housing 2 contains an additional cavity 16 housing, among other things, means for protecting the printed circuit boards 6 against electrostatic current nuisances. The cavity 16 can also contain an additional thermal filter to prevent operation under unusual temperatures.

D'autre part, le kit objet de la présente invention comporte, en plus du boîtier 2, un support 17 pour accrocher ce dernier au-dessus d'une zone à éclairer et intégrant des moyens de pilotage des cartes de circuit électronique 6 et par conséquent des diodes électroluminescentes 7, reliés audit boîtier 2 par une liaison filaire. Une telle caractéristique permet, si nécessaire, de procéder à un remplacement des moyens de pilotage sans avoir à accéder ou à démonter le boîtier 2.On the other hand, the kit which is the subject of the present invention comprises, in addition to the housing 2, a support 17 for hanging the latter above an area to be illuminated and integrating means for controlling the electronic circuit boards 6 and consequently the light-emitting diodes 7, connected to said housing 2 by a wired connection. Such a feature makes it possible, if necessary, to carry out a replacement of the control means without having to access or dismantle the housing 2.

Dans la variante de réalisation illustrée, le support est défini par un mât 17 destiné à être ancré au sol, par exemple le long d'une chaussée, ou fixé sur une façade ou un mur d'un bâtiment. Bien entendu, d'autres types de supports sont également envisageables, tels que par exemple un câble tendu entre deux bâtiments respectivement situés de part et d'autre d'une chaussée.In the illustrated embodiment variant, the support is defined by a mast 17 intended to be anchored to the ground, for example along a roadway, or fixed to a facade or a wall of a building. Of course, other types of supports are also conceivable, such as for example a cable stretched between two buildings respectively located on either side of a roadway.

Le boîtier 2 est par ailleurs relié au mât 17 au moyen d'un organe de solidarisation 18. Ce dernier comporte un logement 19, au creux duquel est fixé le boîtier 2, par exemple au moyen de vis vissées dans des orifices taraudés (non illustrés) dont est pourvu le fond 3 du boîtier 2 dont l'épaisseur est adaptée en conséquence. Dans la variante de réalisation illustrée, le logement 19 est solidaire d'une carrosserie 21 recouvrant le fond 3 du boîtier 2 et octroyant au luminaire 1 un aspect esthétique particulier.The housing 2 is furthermore connected to the mast 17 by means of a securing member 18. The latter comprises a housing 19, in the hollow of which the housing 2 is fixed, for example by means of screws screwed into tapped holes (not illustrated) with which the bottom 3 of the housing 2 is provided, the thickness of which is adapted accordingly. In the illustrated embodiment variant, the housing 19 is secured to a body 21 covering the bottom 3 of the housing 2 and giving the luminaire 1 a particular aesthetic appearance.

L'organe de solidarisation 18 comporte par ailleurs un embout 20 solidaire du logement 19 et permettant la fixation de ce dernier au mât 17 par des moyens d'assemblage appropriés. Il convient de préciser que dans le cadre de l'invention, l'organe de solidarisation 18 peut présenter de multiples autres formes que celles illustrées à la figure 1, chacune d'entre elles conférant au luminaire 1 le design recherché, qui peut avantageusement être extrêmement épuré ou à l'inverse de style par exemple baroque pour répondre à tous les goûts.The securing member 18 also comprises an end piece 20 secured to the housing 19 and allowing the latter to be fixed to the mast 17 by appropriate assembly means. It should be noted that within the framework of the invention, the securing member 18 may have multiple other shapes than those illustrated in FIG. figure 1 , each of them giving the luminaire 1 the desired design, which can advantageously be extremely refined or conversely in a baroque style, for example, to suit all tastes.

Par ailleurs, il peut également être prévu d'utiliser un organe de solidarisation 180 (cf. fig. 5) présentant un embout 200 relié à un logement 190 au moyen d'une articulation 22 permettant de modifier l'orientation du logement 190, dans lequel est fixé le boîtier 2, par rapport à l'embout 200. Une telle structure d'organe de solidarisation 180 permet, lors de l'installation d'un luminaire obtenu au moyen d'un kit selon l'invention, de procéder éventuellement à des réglages permettant d'ajuster la position du boîtier 2 au-dessus de la zone à éclairer afin de diriger l'éclairage de manière plus précise vers celle-ci.Furthermore, it may also be possible to use a 180 solidarization organ (cf. fig. 5 ) having an end piece 200 connected to a housing 190 by means of a joint 22 making it possible to modify the orientation of the housing 190, in which the housing 2 is fixed, relative to the end piece 200. Such a structure of a securing member 180 makes it possible, when installing a luminaire obtained by means of a kit according to the invention, to possibly make adjustments making it possible to adjust the position of the housing 2 above the area to be illuminated in order to direct the lighting more precisely towards it.

Tel qu'il ressort clairement de ce qui précède, le kit selon la présente invention permet d'atteindre les objectifs fixés en préambule. En effet, chacun des éléments structurels le composant est disponible sous forme d'une gamme infinie parmi laquelle il peut être spécifiquement sélectionné pour composer à chaque fois des luminaires différents.As is clear from the above, the kit according to the present invention makes it possible to achieve the objectives set in the preamble. Indeed, each of the structural elements composing it is available in the form of an infinite range from which it can be specifically selected to compose different luminaires each time.

Ainsi, le boîtier 2 peut présenter toutes les formes possibles et imaginables et héberger un nombre variable de cartes de circuit imprimées 6 portant la quantité de diodes électroluminescentes 7 nécessaire à la puissance d'éclairage souhaitée.Thus, the housing 2 can have any possible and imaginable shape and accommodate a variable number of printed circuit boards 6 carrying the quantity of light-emitting diodes 7 necessary for the desired lighting power.

De plus, comme déjà indiqué ci-dessus, le support peut se présenter sous la forme d'un mât 17 très simple ou sous toute autre forme, et peut en outre présenter en tant que tel un aspect esthétique original ou comporter des accessoires lui conférant un tel aspect. Il en va de même en ce qui concerne l'organe de solidarisation 18.Furthermore, as already indicated above, the support may be in the form of a very simple mast 17 or in any other form, and may furthermore present as such an original aesthetic appearance or include accessories giving it such an appearance. The same applies with regard to the securing member 18.

En d'autres termes, grâce à ses trois éléments structurels de base, le kit selon l'invention permet d'aboutir à un luminaire aux allures très modernes, plus petit et plus plat que les luminaires classiques. Une forme claire et très épurée peut notamment être obtenue en associant un boîtier 2 à un support réduit à sa plus simple structure au moyen d'un organe de solidarisation compact dépourvu de carrosserie. Une telle forme répond parfaitement aux exigences actuelles des marchés correspondants.In other words, thanks to its three basic structural elements, the kit according to the invention makes it possible to achieve a luminaire with a very modern appearance, smaller and flatter than conventional luminaires. A clear and very refined shape can in particular be obtained by associating a housing 2 with a support reduced to its simplest structure by means of a compact securing member without a body. Such a shape perfectly meets the current requirements of the corresponding markets.

Par ailleurs, le kit selon l'invention permet de réaliser un luminaire 1 conçu pour fonctionner en moyenne une vingtaine d'années, indépendamment de toute opération de maintenance. A cet effet, le boîtier 2 est équipé de moyens garantissant son étanchéité et son inviolabilité, son alimentation électrique s'effectuant par l'extérieur, grâce à un câblage étanche réalisé en usine et adapté à la configuration de l'installation.Furthermore, the kit according to the invention makes it possible to produce a luminaire 1 designed to operate for an average of twenty years, independently of any maintenance operation. To this end, the housing 2 is equipped with means guaranteeing its sealing and inviolability, its power supply being carried out from the outside, thanks to sealed wiring produced in the factory and adapted to the configuration of the installation.
