Abstract

The reflector surface is held within a support (301) which is manufactured separately from the lamp carrier (302). The reflector support (301) includes supports rails extending to the lamp support. These are arranged with spaces between them to maintain adequate ventilation. The reflector assembly (300) goes through a series of manufacturing stages, including the application of a powder to the internal surface (310). The reflector surface is held within a support (301) which is manufactured separately from the lamp carrier (302). The reflector support (301) includes supports elements (303, 304) which comprise rails extending to the lamp support. These are arranged with spaces between them, such that the lamp may be inserted easily. The rails define an open space (308) between the reflector and the lamp carrier, such that adequate ventilation is maintained around the lamp. The lamp carrier (302) is finally fixed to the reflector support element (301) by means of cantering pins (316) and rods (317).

Description

La présente invention a pour objet un dispositif réflecteur pour projecteur équipant les véhicules automobiles, qui assure une utilisation durable d'un projecteur et qui permet une grande maniabilité des réflecteurs lors de leur fabrication.The present invention relates to a reflector device for a projector fitted to motor vehicles, which ensures durable projector and allows great maneuverability of the reflectors during their manufacture.

Elle a essentiellement pour but de proposer une réalisation particulière de dispositif réflecteur qui permet notamment d'assurer une bonne aération pour une source lumineuse qui est placée dans ledit dispositif réflecteur, et qui permet une manipulation sur les chaínes de fabrication qui limite les risques d'endommagement d'une surface réfléchissante du dispositif réflecteur.Its main purpose is to propose a realization particular reflective device which allows in particular to ensure a good ventilation for a light source that is placed in said reflecting device, and which allows manipulation on the chains of manufacturing that limits the risk of damage to a surface reflective reflector device.

Le domaine de l'invention est, d'une façon générale, celui des projecteurs de véhicule automobile. Dans ce domaine, on connaít différents types de projecteurs, parmi lesquels on trouve essentiellement :

  • des feux de position, d'intensité et de portée faible ;
  • des feux de croisement, ou codes, d'intensité plus forte et de portée sur la route avoisinant 70 mètres, qui sont utilisés essentiellement la nuit et dont la répartition du faisceau lumineux est telle qu'elle permet de ne pas éblouir le conducteur d'un véhicule croisé ;
  • des feux de route longue portée, et des feux de complément de type longue portée, dont la zone de vision sur la route avoisine 200 mètres, et qui doivent être éteints lorsque l'on croise un autre véhicule afin de ne pas éblouir son conducteur ;
  • des feux anti-brouillard.
The field of the invention is, in general, that of motor vehicle headlights. In this field, we know different types of projectors, among which we find essentially:
  • position, intensity and low range lights;
  • low beam, or codes, of greater intensity and range on the road of about 70 meters, which are used mainly at night and whose distribution of the light beam is such that it does not dazzle the driver of a crossover vehicle;
  • long-range headlamps, and long-range supplement lights, whose vision zone on the road is approximately 200 meters, and which must be extinguished when crossing another vehicle so as not to dazzle its driver;
  • fog lights.

Le dispositif réflecteur selon l'invention peut être indifféremment utilisé pour l'un quelconque de ces projecteurs. Il sera plus particulièrement décrit dans le cadre de projecteurs, dit elliptiques, dans lesquels on fait intervenir une lentille de projection, mais il pourrait également être intégré dans la réalisation de projecteurs paraboliques, dans lesquels on n'utilise pas de lentille de projection.The reflector device according to the invention can be indifferently used for any of these projectors. It will be more particularly described in the context of so-called elliptical projectors, in which a projection lens but it could also be integrated into the production of parabolic spotlights, in which no projection lens.

Les différents types de projecteurs utilisent tous une source lumineuse associée à un réflecteur. Un exemple de projecteur avec un dispositif réflecteur utilisé dans l'état de la technique est illustré à la figure 1.The different types of projectors all use one source light associated with a reflector. An example of a projector with a reflector device used in the state of the art is illustrated in Figure 1.

Sur cette figure, un projecteur 100 du type elliptique, c'est à dire faisant intervenir une lentille de projection 103, comporte deux parties principales : une première partie 101 est constituée par la lentille 103 et par un support de lentille 104. Une deuxième partie 102 est constituée par un dispositif réflecteur de l'état de la technique. Le dispositif réflecteur 102 est constitué d'une unique pièce remplissant à la fois la fonction de réflecteur au niveau d'une partie arrondie 105, et de porte lampe au niveau d'une extrémité arrière 106. Le réflecteur 105 a pour fonction de réfléchir des signaux lumineux produits par une source lumineuse placée au coeur de la partie arrondie pour produire un faisceau lumineux satisfaisant les exigences imposées par différentes normes. Le porte lampe 106 a pour fonction de maintenir la source lumineuse dans une position appropriée au sein du réflecteur 105.In this figure, a projector 100 of the elliptical type, that is to say involving a projection lens 103, has two parts main parts: a first part 101 is constituted by the lens 103 and by a lens holder 104. A second portion 102 is constituted by a reflecting device of the state of the art. Reflector device 102 is consisting of a single piece fulfilling both the reflector function at the level of a rounded portion 105, and of a lamp holder at a rear end 106. The reflector 105 has the function of reflecting light signals produced by a light source placed in the heart of the rounded part to produce a light beam meeting the requirements imposed by different standards. The lamp holder 106 has the function of keep the light source in an appropriate position within the reflector 105.

La jonction entre le porte lampe 106 et le réflecteur 105 est assurée par un élément cylindrique 107. Dans l'état de la technique, l'élément cylindrique 107 est clos : sa partie latérale ne présente aucune ouverture car pour ménager des ouvertures, le moule servant à fabriquer le dispositif réflecteur devrait faire intervenir des tiroirs et serait trop complexe et coûteux à réaliser pour la fabrication de cette pièce ; la base (au niveau du porte lampe 106) et le sommet (au niveau du réflecteur 105) de l'élément cylindrique 107 sont par ailleurs, au moins en grande partie, obturés par différentes parties de la source lumineuse qui est introduite dans le réflecteur 105.The junction between the lamp holder 106 and the reflector 105 is ensured by a cylindrical element 107. In the state of the art, the element cylindrical 107 is closed: its lateral part has no opening because to provide openings, the mold used to manufacture the device reflector should involve drawers and would be too complex and expensive to realize for the manufacture of this piece; the base (at the door lamp 106) and the top (at the level of the reflector 105) of the element cylindrical 107 are also, at least largely, plugged by different parts of the light source that is introduced into the reflector 105.

Le fait que l'élément cylindrique 107 soit clos, notamment au niveau de sa partie latérale pose un premier problème : le dispositif réflecteur 102 n'est pas assez aéré, et ceci peut nuire à un bon fonctionnement prolongé de la source lumineuse lorsqu'elle est allumée ; en effet, l'augmentation de la température est très rapide dans le dispositif réflecteur 102, pouvant aller jusqu'à la destruction de la source lumineuse.The fact that the cylindrical element 107 is closed, especially at the level of of its lateral part poses a first problem: the reflector device 102 is not ventilated enough, and this can interfere with prolonged the light source when turned on; indeed, the increase of the temperature is very fast in the reflector device 102, which can go until the destruction of the light source.

Un deuxième problème rencontré avec les dispositifs réflecteurs de l'état de la technique est illustré à la figure 2. Sur cette figure, une section verticale du dispositif réflecteur 102 est représentée. Une surface interne 201 du réflecteur 105 est ainsi apparente. L'élément cylindrique comporte notamment une paroi externe 202, qui était visible sur la figure 1, et une paroi interne 203. La paroi interne 203 constitue également un cylindre fermé. Lors de la fabrication dès dispositifs réflecteurs 105, il est nécessaire de recouvrir la surface interne 201 du réflecteur 105 d'une poudre qui se transformera en vernis réfléchissant. Il faut donc faire circuler le dispositif réflecteur 102 sur des chaínes de fabrication, et le maintenir pour pouvoir asperger la surface interne 201. Dans l'état de la technique, on utilise un ou plusieurs crochets 204. Le problème est que, compte tenu du caractère cylindrique et fermé de la paroi interne 203, les crochets 204 sont obligés de maintenir le dispositif réflecteur 102 au niveau d'une extrémité 205 de la surface interne 201, ce qui risque d'endommager cette dernière. En effet, les surfaces internes de réflecteur sont calculées avec précision et doivent par la suite subir le moins de contraintes mécaniques possible, et être couvertes par une surface de vernis aussi homogène que possible.A second problem encountered with the reflector devices of the state of the art is illustrated in Figure 2. In this figure, a section vertical of the reflector device 102 is shown. An internal surface 201 of the reflector 105 is thus apparent. The cylindrical element comprises including an outer wall 202, which was visible in Figure 1, and a inner wall 203. The inner wall 203 also constitutes a cylinder closed. When manufacturing reflector devices 105, it is necessary to cover the inner surface 201 of the reflector 105 with a powder which is will turn into a reflective varnish. It is therefore necessary to circulate the device reflector 102 on production lines, and maintain it to be able to spraying the inner surface 201. In the state of the art, one or 204. The problem is that, given the cylindrical and closed of the inner wall 203, the hooks 204 are obliged to maintain the reflector device 102 at one end 205 of the internal surface 201, which may damage the latter. Indeed, internal reflector surfaces are calculated accurately and must by following the least possible mechanical stress, and be covered by a varnish surface as homogeneous as possible.

Le dispositif selon l'invention répond aux deux problèmes principaux qui viennent d'être exposés. D'une façon générale, on propose dans l'invention un dispositif réflecteur qui d'une part assure une bonne aération d'une source lumineuse placée dans le dispositif réflecteur, et qui d'autre part facilite le passage du dispositif réflecteur sur des chaínes de fabrication pour recouvrir de poudre une surface interne du réflecteur. Un des intérêts du dispositif réflecteur selon l'invention est qu'il peut toujours être fabriqué avec des moules, sans opérations ultérieures d'usinage des pièces moulées qui risqueraient d'endommager la surface interne du réflecteur, les moules utilisés pouvant par ailleurs toujours être de conception simple, c'est à dire notamment sans présence de tiroirs de moulage.The device according to the invention answers the two main problems which have just been exposed. Generally, we propose in the invention a reflector device which on the one hand ensures good ventilation of a light source placed in the reflecting device, and who else share facilitates the passage of the reflector device on production lines for coating an inner surface of the reflector with powder. One of the interests of the reflector device according to the invention is that it can still be manufactured with molds, without subsequent machining operations of castings which could damage the inner surface of the reflector, the molds used, which can always be of simple design, that is to say especially without the presence of molding drawers.

A cet effet, dans l'invention, on propose un dispositif réflecteur dans lequel un élément réflecteur et un élément porte lampe sont fabriqués séparément avant d'être solidarisés. L'élément réflecteur ainsi fabriqué comporte un ensemble de supports qui sont disposés de telle sorte qu'une source lumineuse installée ultérieurement dans le dispositif réflecteur pourra être aérée de façon satisfaisante. L'élément porte lampe est solidarisé avec l'élément réflecteur au niveau des supports au moyen de pions de centrage et de tiges d'assemblage.For this purpose, in the invention, a reflector device is proposed in which a reflector element and a lamp element are manufactured separately before being secured. The reflective element thus manufactured has a set of supports that are arranged in such a way that light source subsequently installed in the reflecting device may be ventilated satisfactorily. The lamp holder element is secured with the reflector element at the supports by means of centering pins and assembly rods.

L'invention concerne donc essentiellement un dispositif réflecteur pour projecteur de véhicule automobile, le dispositif réflecteur comportant un élément réflecteur comprenant une surface réfléchissante interne, une surface externe, et une ouverture sur une partie arrière de l'élément réflecteur pour introduire une source lumineuse caractérisé en ce que le dispositif réflecteur comporte un élément porte lampe solidarisé à l'élément réflecteur au moyen d'un ensemble de supports, lesdits supports étant disposés de sorte à créer un espace ouvert entre l'élément porte lampe et l'élément réflecteur. De préférence, au moins un desdits supports prend appui sur une base (311) de l'élément réflecteur (301), ladite base (311) étant distincte de la surface externe (309) de l'élément réflecteur (301).The invention therefore essentially relates to a reflector device for motor vehicle headlamp, the reflector device having a reflector element comprising an internal reflecting surface, a outer surface, and an opening on a back part of the element reflector for introducing a light source, characterized in that the reflector device comprises a lamp holder element secured to the element reflector by means of a set of supports, said supports being arranged so as to create an open space between the lamp holder element and the reflective element. Preferably, at least one of said supports takes pressing on a base (311) of the reflector element (301), said base (311) being distinct from the outer surface (309) of the reflector element (301).

Le dispositif selon l'invention peut en outre présenter une ou plusieurs des caractéristiques suivantes :

Sur les différentes figures, les éléments qui sont communs à plusieurs figures auront conservé les mêmes références. La figure 3 montre un dispositif réflecteur 300 selon l'invention en section verticale, qui est composé notamment d'un élément réflecteur 301 et d'un élément porte lampe 302. L'élément porte lampe 302 et l'élément réflecteur 301 comportent respectivement une première ouverture 314 et une deuxième ouverture 315 (visibles notamment à la figure 6) prévues pour laisser un passage destiné à l'installation d'une source lumineuse. Un premier élément de support 303, hachuré sur la figure 3 car il est situé dans le plan de section, et un deuxième élément de support 304 sont visibles sur cette figure. Les éléments de support, qui seront désignés par le terme colonne, sont de forme allongée, c'est à dire qu'ils ont une longueur l nettement supérieure à leur hauteur h, qui, dans un exemple particulier, sont respectivement de l'ordre de 60 millimètres et 15 millimètres; l'épaisseur e de ces colonnes étant de l'ordre de 2 millimètres au niveau d'une première extrémité 307, dite extrémité de fixation, et de l'ordre de 5 millimètres au niveau d'une deuxième extrémité 306, dite extrémité moulée.In the different figures, the elements that are common to several figures will have kept the same references. Figure 3 shows a reflector device 300 according to the invention in vertical section, which is composed in particular of a reflector element 301 and a door element lamp 302. The lamp holder element 302 and the reflector element 301 respectively comprise a first opening 314 and a second opening 315 (visible in particular in Figure 6) provided to leave a passage intended for the installation of a light source. A first element 303, hatched in Figure 3 because it is located in the plane of section, and a second support member 304 are visible on this Fig. The support elements, which will be referred to as the column, are of elongated shape, ie they have a length l clearly greater than their height h, which in a particular example are respectively of the order of 60 millimeters and 15 millimeters; the thickness e of these columns being of the order of 2 millimeters at a first end 307, said fixing end, and of the order of 5 millimeters at level of a second end 306, said molded end.

Dans l'exemple illustré, le dispositif réflecteur 300 comporte une troisième colonne 305, visible sur la figure 5. La troisième colonne 305 n'est pas visible sur la figure 3 car elle est alignée avec la deuxième colonne 304, c'est à dire que les plans, appelés plans supports, contenant les surfaces constituant la hauteur de chacune de ces colonnes sont confondus. Comme on peut le voir sur les figures 3 et 5, la première colonne 303 définit un plan contenant une surface constituant sa hauteur, ledit plan étant perpendiculaire aux plans supports de la deuxième colonne 304 et de la troisième colonne 305. Cette disposition des colonnes constitue un excellent détrompeur au moment de l'assemblage de l'élément réflecteur 301 et de l'élément porte lampe 302, une unique position d'assemblage étant possible. Il est cependant possible de réaliser d'autres autrement le détrompage lors de l'assemblage de l'élément réflecteur 301 et de l'élément porte lampe 302.In the example illustrated, the reflector device 300 comprises a third column 305, visible in FIG. 5. The third column 305 is not visible in Figure 3 because it is aligned with the second column 304, that is, the planes, called support planes, containing the surfaces constituting the height of each of these columns are merged. As can be seen in Figures 3 and 5, the first column 303 defines a plan containing a surface constituting its height, said plane being perpendicular to the support planes of the second column 304 and the third column 305. This arrangement of the columns constitutes an excellent key at the time of assembly of the reflector element 301 and the lamp holder element 302, a single assembly position being possible. However, it is possible to make others otherwise foolproofing of the assembly of the reflector element 301 and the lamp holder element 302.

La disposition des colonnes de support est telle qu'elle laisse apparaítre un espace vide 308 entre ces colonnes et entre l'élément porte lampe 302 et l'élément réflecteur 301. En d'autres termes, entre deux colonnes quelconques, il existe une ouverture qui permet une circulation de fluide, et plus particulièrement d'air, entre l'extérieur du dispositif réflecteur 300 et un espace compris entre l'élément réflecteur 301 et l'élément porte lampe 302. L'élément de forme cylindrique 107 de l'état de la technique a disparu et a été remplacé par un système de fixation de l'élément porte lampe 302 faisant intervenir des colonnes de support. De telles ouvertures permettent une aération optimale d'une source lumineuse introduite dans le dispositif réflecteur 300.The arrangement of the support columns is such that it leaves appear an empty space 308 between these columns and between the door element 302 lamp and the reflector element 301. In other words, between two columns, there is an opening which allows a circulation of fluid, and more particularly air, between the outside of the reflector device 300 and a space between the reflector element 301 and the door element 302. The cylindrical element 107 of the state of the art has disappeared and was replaced by a fastening system of the door element lamp 302 involving support columns. Such openings allow optimal ventilation of a light source introduced into the reflector device 300.

L'extrémité moulée 306 de chaque colonne épouse la forme d'une surface externe 309 de l'élément réflecteur 301, comme illustré à la figure 6. Ceci permet de répartir l'ensemble des forces de pression, qui pourraient s'exercer sur les différentes colonnes, sur une surface maximale de l'élément réflecteur, limitant ainsi les risques de déformation d'une surface interne 310, dite surface photométrique, destinée à réfléchir les signaux lumineux produits par la source lumineuse installée dans le dispositif réflecteur. Dans un mode de réalisation perfectionné, l'extrémité moulée 306 d'au moins une colonne de support s'achève au niveau d'une surface 311 servant à la fixation d'un support de lentille de type de celui présent à la figure 1. La surface 311 est appelée la base de l'élément réflecteur 301. Elle ne constitue pas le verso de la surface interne 310 réfléchissante. Dans l'exemple illustré, cette base 311 est disposée dans un plan de sortie du faisceau lumineux hors du dispositif réflecteur 301. Une telle réalisation permet de limiter encore plus les contraintes mécaniques qui pourraient endommager la surface interne 310 de l'élément réflecteur 301.The molded end 306 of each column is in the shape of a outer surface 309 of the reflector element 301, as shown in FIG. This makes it possible to distribute all the pressure forces, which could practice on the different columns, on a maximum surface of the reflective element, thus limiting the risk of deformation of a surface internal 310, said photometric surface, for reflecting the signals light produced by the light source installed in the device reflector. In an improved embodiment, the molded end 306 at least one support column ends at a surface 311 used to attach a lens holder of the type of the one present at the The surface 311 is called the base of the reflector element 301. It does not constitute the back of the reflective inner surface 310. In illustrated example, this base 311 is disposed in an exit plane of the light beam out of the reflector device 301. Such an embodiment can further limit the mechanical constraints that could to damage the inner surface 310 of the reflector element 301.

Une ou plusieurs colonnes de support peuvent par ailleurs comporter un ou plusieurs éléments de renfort. De tels éléments de renfort sont visibles en hachuré sur la figure 6 : on y voit, sur les colonnes 303 et 304 un élément de renfort central 312, situé approximativement au centre de chaque colonne, et un élément de renfort intérieur 313, situé à proximité des ouvertures 314 et 315 prévues pour introduire la source lumineuse. Les éléments de renfort 312 et 313 se traduisent par des protubérances sur les colonnes de support. Elles servent d'une part à limiter les contraintes mécaniques qui pourraient endommager la surface interne 310 de l'élément réflecteur 301, et d'autre part à évacuer, par convection une partie de la chaleur générée par la source lumineuse.One or more support columns may also have one or more reinforcing elements. Such reinforcing elements are visible hatched in Figure 6: we see, on columns 303 and 304 an element central reinforcement 312, located approximately in the center of each column, and an inner reinforcing member 313, located near the openings 314 and 315 provided for introducing the light source. The reinforcement elements 312 and 313 result in protuberances on the support columns. They serve on the one hand to limit the constraints mechanical that could damage the inner surface 310 of the element reflector 301, and on the other hand to evacuate, by convection, part of the heat generated by the light source.

L'élément porte lampe 302 est de forme circulaire, et est susceptible de recevoir dans son épaisseur un élément en forme d'anneau, servant de socle à la source lumineuse, qui vient se fixer, par exemple par un mouvement de rotation, dans l'élément porte lampe. Dans l'invention, afin de conserver des moules simples et de ne pas ajouter d'opérations d'usinage, l'élément porte lampe 302 et l'élément réflecteur 301 incluant les colonnes de support sont réalisés dans des moules distincts. Ce procédé de fabrication du dispositif réflecteur selon l'invention permet en outre de réaliser ces deux éléments dans des matériaux différents. Dans un exemple de réalisation, l'élément réflecteur 301 et les colonnes de support sont réalisés en aluminium, l'élément porte lampe étant réalisé dans un alliage de zinc et d'aluminium. D'autres métaux, alliages ou matières plastiques peuvent également être utilisés dans la réalisation de ces pièces, l'élément réflecteur pouvant notamment être réalisé dans un matériau thermodurcissable ou dans un matériau thermoplastique.The lamp holder element 302 is circular in shape and is capable of to receive in its thickness a ring-shaped element serving as a base to the light source, which is fixed, for example by a rotational movement, in the lamp holder element. In the invention, in order to keep simple molds and not add machining operations, the lamp holder element 302 and the reflector element 301 including the columns of support are made in separate molds. This method of manufacture of the reflector device according to the invention also makes it possible to realize these two elements in different materials. In an example of embodiment, the reflector element 301 and the support columns are made of aluminum, the lamp holder element being made of an alloy of zinc and aluminum. Other metals, alloys or plastics can also be used in the realization of these parts, the element reflector may in particular be made of a material thermosetting or in a thermoplastic material.

La solidarisation de l'élément porte lampe 302 et de l'élément réflecteur 301 s'effectue au niveau des extrémités de fixation 307 des différentes colonnes de support. Dans l'exemple considéré, chacune de ces extrémités comporte un pion de positionnement 316 d'une source lumineuse qui sera disposée dans l'élément porte lampe 302 et une tige de centrage et de maintien 317. Le pion de positionnement 316 assure le bon positionnement de la source lumineuse par rapport à la surface interne 310 de l'élément réflecteur 302. Chaque tige de centrage et de maintien 317 est destinée à venir s'introduire dans une ouverture spécifique de l'élément porte lampe 302. La présence du pion est utile pour que le jeu entre une colonne de support et l'élément porte lampe soit nul ou quasiment nul. Des ouvertures spécifiques sont également prévues dans l'élément porte lampe 302 pour recevoir chaque pion de positionnement 316.The fastening of the lamp holder element 302 and the element reflector 301 is made at the fixing ends 307 of the different support columns. In the example considered, each of these ends comprises a positioning pin 316 of a light source which will be arranged in the lamp holder element 302 and a centering rod and 317. The positioning pin 316 ensures the correct positioning of the light source relative to the inner surface 310 of the reflector element 302. Each centering and holding rod 317 is intended to be introduced into a specific opening of the element lamp holder 302. The presence of the pawn is useful for the game between a support column and the lamp holder element is zero or virtually zero. of the specific openings are also provided in the lamp holder element 302 to receive each positioning pin 316.

Une fois que chaque tige de centrage et de maintien 317 et chaque pion de positionnement 316 sont introduits dans leur ouverture respective, une opération de bouterollage est effectuée. Cette opération consiste à déformer l'extrémité de chaque tige de centrage et de maintien 317, pour venir l'écraser sur des éléments de maintien 318 prévus autour de chaque ouverture destinée à recevoir une tige de maintien. Un tel mécanisme de solidarisation de l'élément porte lampe 302 et de l'élément réflecteur 301 rendent l'association de ces deux pièces définitive. Un détachement de ces deux pièces entraínerait nécessairement la détérioration d'au moins l'un des éléments.Once each centering and holding rod 317 and each positioning pin 316 are introduced into their respective aperture, a peel operation is performed. This operation consists of deform the end of each centering and holding rod 317, to come crush it on 318 holding elements provided around each opening for receiving a holding rod. Such a mechanism of fastening the lamp holder element 302 and the reflector element 301 make the association of these two pieces final. A detachment of these two pieces would necessarily result in the deterioration of at least one of the elements.

Un autre avantage inhérent à la structure du dispositif réflecteur selon l'invention est que les crochets 204, présents sur les chaínes de fabrication, peuvent désormais s'agripper au niveau des ouvertures 308, et ainsi ne plus endommager la surface interne 310 de l'élément réflecteur 301. Another advantage inherent in the structure of the reflector device according to the invention is that the hooks 204, present on the production lines, can now grip at the openings 308, and thus no longer to damage the inner surface 310 of the reflector element 301.

En conclusion, le réflecteur avec porte lampe selon l'invention est très avantageux, notamment parce que les plots sur lesquels le porte lampe est boutterolé s'appuient de préférence sur la face avant du réflecteur, il n'y a donc pas (moins) de déformation de celui-ci lors du montage. Le réflecteur et le porte lampe sont de préférence métalliques (aluminium ou alliage d'aluminium). Cette matière hautement conductrice associée au type de plots déjà décrits (« ailettes de radiateur ») favorise une évacuation de la chaleur satisfaisante.In conclusion, the reflector with lamp holder according to the invention is very advantageous, especially because the studs on which the lamp holder is the top of the backrest preferably rest on the front of the reflector, there is therefore no (less) deformation of it during assembly. The reflector and the lamp holder are preferably metallic (aluminum or alloy aluminum). This highly conductive material associated with the type of already described pads ("radiator fins") promotes evacuation of the satisfactory heat.
