More specifically, the folder 14 comprises a central reflective portion 14 1 and two lateral portions 14 2 in the form of a support arm 4 ( figure 1 ). This fixation will be further detailed in relation to the figure 6 .
  • the folder 14 thus has a transverse U-shaped profile where only the central portion 14 1 is optically active.
  • the folder can be made from a portion of sheet metal, by shaping, folding and cutting.
  • the front portion 6 2 comprises on its upper surface two bosses 6 3 . These bosses are intended to ensure exact positioning in the vertical direction of the support 4, as will be detailed in connection with the Figures 3 and 4 . These bosses can be more numerous.

It is indeed important that the folder 14, more particularly its central portion 14 1 reflecting, is parallel to the upper surface of the rear portion 6 1 of the radiator 6. Indeed any misalignment of the reflective surface of the folder 14 is likely to significantly modify the photometry of the light beam of the module. It is therefore important to be able to accurately position the folder 14 not only in translation in the longitudinal direction but also vertically and in rotation about a transverse axis.
  • the ribs 6 6 provide vertical and rotational positioning about a transverse axis of the folder 14. They also prevent light leakage between the underside of the central portion 14 1 and the upper face of the rear portion 6 1 of the radiator.

  • these ribs may deviate from that illustrated in figures 5 and 6 . Indeed, they could for example include two transverse ribs parallel and distant from each other. They could also have a U-shaped profile or in the form of a rectangle. It could also be several point bosses.
  • the figure 7 is an elevation view of the module of the figure 1 . Unlike the figure 3 , the figure 7 illustrates the module provided with fixing screws 20 and 22, visible in particular at the figure 5 . As can be seen at figure 7 the cutting axis VIII-VIII passes through an oblong hole 4 5 of the support 4 as well as one of the pins 6 5 of the radiator 6.

Description

L'invention a trait au domaine de l'éclairage, plus particulièrement de l'éclairage automobile. L'invention a trait à un module d'éclairage de projecteur pour véhicule automobile.The invention relates to the field of lighting, more particularly to automotive lighting. The invention relates to a projector lighting module for a motor vehicle.

Le document de brevet publié EP 2 428 725 A2 divulgue un module d'éclairage de projecteur automobile. Le module d'éclairage en question comprend une source lumineuse du type diode à électroluminescence (LED) montée sur une platine disposée sur un radiateur de refroidissement de ladite diode. Le module comprend également une première surface réfléchissante en forme de demi-coquille et apte à réfléchir les rayons émis par la source lumineuse vers une deuxième surface réfléchissante, dite plieuse, avec un bord de coupure du faisceau d'éclairage. Le module d'éclairage comprend également une lentille disposée à l'avant de la deuxième surface réfléchissante. Les rayons réfléchis par la première surface réfléchissante et qui passent à l'avant du bord de coupure de la pieuse rencontrent la lentille et sont déviés par celle-ci. Les rayons rencontrant la deuxième surface réfléchissante, au lieu de rencontrer la lentille en sa partie inférieure avec un angle d'incidence plus faible que les rayons précédents, sont réfléchis vers la partie supérieure de la lentille avec un angle d'incidence essentiellement identique. Ces rayons sont alors déviés par la lentille vers le bas du faisceau au lieu d'être déviés vers le haut, réalisant ainsi une coupure typique d'un faisceau d'éclairage du type « code » ou encore feux de croisement. Dans ce module, une pièce principale sert de support à la lentille, à la surface réfléchissante en forme de demi-coquille et à la plieuse. Cette pièce est alors fixée au radiateur. Ce dernier supporte directement la platine avec la source lumineuse. Le positionnement longitudinal entre la pièce principale et le radiateur s'opère au moyen d'oeillets sur la pièce principale coopérant par engagement avec des fûts sur le radiateur. Des vis de fixation sont ensuite vissées dans les fûts afin de sécuriser la pièce principale sur le radiateur. La pièce principale comprend des surfaces de butées coopérant directement avec le radiateur en vue de son positionnement vertical. Cet enseignement est intéressant en ce que la pièce principale permet d'assurer un positionnement relatif précis entre la lentille, la surface réfléchissante, la plieuse et le radiateur. Or la source lumineuse manque de faire partie des éléments qui sont directement positionnés les uns par rapport aux autres par la pièce principale. Cela signifie qu'un soin particulier doit être apporté lors de son positionnement sur le radiateur et ce essentiellement par rapport aux zones de référence du radiateur pour la pièce principale.The published patent document EP 2 428 725 A2 discloses a car projector lighting module. The lighting module in question comprises a light-emitting diode-type light source (LED) mounted on a plate disposed on a cooling radiator of said diode. The module also comprises a first reflective surface in the form of a half-shell and able to reflect the rays emitted by the light source towards a second reflective surface, called a bending surface, with a cutting edge of the illumination beam. The lighting module also includes a lens disposed at the front of the second reflective surface. The rays reflected by the first reflective surface and which pass in front of the cutting edge of the pious meet the lens and are deflected by it. The rays meeting the second reflecting surface, instead of meeting the lens at its lower part with a lower incidence angle than the previous rays, are reflected towards the upper part of the lens with a substantially identical angle of incidence. These rays are then deflected by the lens towards the bottom of the beam instead of being deflected upwards, thus achieving a typical cutoff of a lighting beam of the "code" type or even dipped beam. In this module, a main part serves as support for the lens, the reflective surface in the form of a half-shell and the folder. This piece is then attached to the radiator. The latter directly supports the plate with the light source. The longitudinal positioning between the main part and the radiator is effected by means of eyelets on the main part cooperating by engagement with drums on the radiator. Fastening screws are then screwed into the drums to secure the main part on the radiator. The main part comprises abutment surfaces cooperating directly with the radiator for vertical positioning. This teaching is interesting in that the main piece ensures a precise relative positioning between the lens, the reflective surface, the folder and the radiator. But the light source fails to be part of the elements that are directly positioned with respect to others by the main room. This means that particular care must be taken when positioning it on the radiator and this essentially with respect to the reference areas of the radiator for the main room.

La figure 1 est une représentation en perspective d'un module d'éclairage conforme à l'invention. Ce module d'éclairage peut être monté dans un projecteur de véhicule automobile. En l'occurrence, ce module produit un faisceau d'éclairage à coupure tel que pour une fonction d'éclairage du type « code » ou encore feux de croisement.The figure 1 is a perspective representation of a lighting module according to the invention. This lighting module can be mounted in a motor vehicle headlight. In this case, this module produces a cut-off lighting beam such as for a lighting function of the "code" type or even dipped beam.

Le module d'éclairage 2 illustré à la figure 1 comprend, essentiellement un radiateur, ou dissipateur thermique, 6 sur lequel est disposée une platine 16 pourvue d'une ou plusieurs sources lumineuses 12, préférentiellement du type diode à électroluminescence. Un support 4 représenté en transparence et s'étendant sur toute la longueur du module est disposé sur le radiateur 6. Le support est en contact avec une lentille 8. Dans la variante de réalisation représentée, il comprend une surface réfléchissante 10. Cette dernière présente une forme générale de demi-coquille recouvrant la source lumineuse 12. Le profil de la surface réfléchissante 10 peut être généralement elliptique avec deux foyers. La source lumineuse est située au premier foyer et une surface réfléchissante 14 est située essentiellement dans le plan de la source lumineuse et avec un bord avant située au niveau du deuxième foyer. La surface réfléchissante 14 est couramment désignée « plieuse » dans la mesure où elle réfléchit une partie des rayons provenant de la surface réfléchissante 10 vers une partie supérieure de la lentille. En effet, en l'absence de la surface réfléchissante 14, les rayons passant à l'arrière du deuxième foyer rencontreraient la lentille à une partie basse avec un angle d'incidence plus faible que ceux passant par le deuxième foyer. Ces rayons seraient alors déviés par la lentille de sorte à former la partie haute du faisceau d'éclairage. Le fait de renvoyer ces rayons vers une partie haute de la lentille permet d'inverser cet effet et de former la partie basse du faisceau. Le bord avant de la plieuse 14 forme ainsi une coupure horizontale du faisceau. On peut par ailleurs observer que la surface réfléchissante de la plieuse 14 forme un ressaut en son milieu de manière à former deux niveaux de coupure différents entre la partie gauche et la partie droite du faisceau d'éclairage, conformément à la réglementation en matière d'éclairage des véhicules en vigueur dans la plupart des pays. L'utilisation d'une plieuse en vue de former un faisceau d'éclairage à coupure est bien connu en soi de l'homme de métier.The lighting module 2 illustrated at figure 1 comprises, essentially a radiator, or heat sink, 6 on which is arranged a plate 16 provided with one or more light sources 12, preferably of the electroluminescence diode type. A support 4 shown in transparency and extending over the entire length of the module is disposed on the radiator 6. The support is in contact with a lens 8. In the embodiment shown, it comprises a reflecting surface 10. The latter presents a general half-shell shape covering the light source 12. The profile of the reflecting surface 10 can be generally elliptical with two foci. The light source is located at the first focus and a reflective surface 14 is located substantially in the plane of the light source and with a leading edge located at the second focus. Reflective surface 14 is commonly referred to as a "bender" in that it reflects a portion of rays from the reflecting surface 10 to an upper portion of the lens. Indeed, in the absence of the reflective surface 14, the rays passing behind the second focus would meet the lens at a lower part with a lower incidence angle than those passing through the second focus. These rays would then be deflected by the lens so as to form the upper part of the illumination beam. The fact of returning these rays to an upper part of the lens makes it possible to reverse this effect and to form the lower part of the beam. The front edge of the folder 14 thus forms a horizontal cut of the beam. It can also be observed that the reflective surface of the folder 14 forms a projection in the middle so as to form two levels of cutoff between the left and right parts of the lighting beam, in accordance with the vehicle lighting regulations in force in most countries. The use of a folder to form a cut-off light beam is well known to those skilled in the art.

Le faisceau d'éclairage est suivant une direction principale couramment appelé axe optique du module. Cet axe correspond également essentiellement à l'axe longitudinal du module.The lighting beam is in a main direction commonly called the optical axis of the module. This axis also essentially corresponds to the longitudinal axis of the module.

On peut également observer à la figure 1 que la platine 16 comprend à sa partie arrière un connecteur 18 pour son branchement au faisceau électrique du projecteur et du véhicule.We can also observe at figure 1 that the plate 16 comprises at its rear part a connector 18 for its connection to the electrical harness of the projector and the vehicle.

La figure 2 illustre le radiateur 6 du module de la figure 1, le radiateur étant équipé seulement de la plieuse 14 et de la platine 16. On peut observer que le radiateur 6 comprend une portion arrière 61 supportant la platine et une portion avant 62. La portion avant 62 est à un niveau inférieur à celui de la portion arrière 61. Le profil du radiateur 6 est similaire à celui d'un escalier, la portion avant 62 correspondant à une première marche et la portion arrière 61 formant une deuxième marche, supérieure à la première.The figure 2 illustrates the radiator 6 of the module of the figure 1 , the radiator being equipped only with the folder 14 and the plate 16. It can be observed that the radiator 6 comprises a rear portion 6 1 supporting the plate and a front portion 6 2 . The front portion 6 2 is at a lower level than the rear portion 6 1 . The profile of the radiator 6 is similar to that of a staircase, the front portion 6 2 corresponding to a first step and the rear portion 6 1 forming a second step, greater than the first.

La plieuse 14 est située essentiellement au niveau du bord avant de la portion arrière 61. Plus précisément, la plieuse 14 comprend une portion centrale réfléchissante 141 et deux portions latérales 142 sous forme de bras de fixation au support 4 (figure 1). Cette fixation sera davantage détaillée en relation avec la figure 6. La plieuse 14 présente ainsi un profil transversal en forme de U où seule la portion centrale 141 est active optiquement. La plieuse peut être réalisée à partir d'une portion de tôle métallique, par mise à forme, pliage et découpage.The folder 14 is located essentially at the front edge of the rear portion 6 1 . More specifically, the folder 14 comprises a central reflective portion 14 1 and two lateral portions 14 2 in the form of a support arm 4 ( figure 1 ). This fixation will be further detailed in relation to the figure 6 . The folder 14 thus has a transverse U-shaped profile where only the central portion 14 1 is optically active. The folder can be made from a portion of sheet metal, by shaping, folding and cutting.

La portion avant 62 comprend sur sa surface supérieure deux bossages 63. Ces bossages sont destinés à assurer un positionnement exact dans la direction verticale du support 4, comme cela va être détaillé en relation avec les figures 3 et 4. Ces bossages peuvent être plus nombreux. Il pourrait également s'agir d'un ou plusieurs bossages s'étendant transversalement, à la manière d'une nervure.The front portion 6 2 comprises on its upper surface two bosses 6 3 . These bosses are intended to ensure exact positioning in the vertical direction of the support 4, as will be detailed in connection with the Figures 3 and 4 . These bosses can be more numerous. It could also be one or more protrusions extending transversely, in the manner of a rib.

La portion avant 62 comprend également, à son bord avant, deux pattes 64 de fixation de la lentille 8 (figure 1), comme cela va être détaillé en relation avec les figures 3 et 4.The front portion 6 2 also comprises, at its front edge, two lugs 6 4 for fixing the lens 8 ( figure 1 ), as will be detailed in relation to the Figures 3 and 4 .

Comme cela est visible à la figure 2, la portion arrière 61 peut comprendre un ou plusieurs pions, en l'occurrence deux pions 63 destinés à traverser des orifices correspondants de la platine 16. Ces pions peuvent être généralement coniques. La platine 16 comprend également des orifices 161 destinés à recevoir des vis de fixation et des trous oblongs 162 destinés à permettre un positionnement longitudinal, c'est-à-dire suivant la direction de l'axe optique, du support 4 par rapport à la platine 16.As can be seen in figure 2 , the rear portion 6 1 may comprise one or more pins, in this case two pins 6 3 for passing through corresponding holes of the plate 16. These pins may be generally conical. The plate 16 also comprises orifices 16 1 intended to receive fastening screws and oblong holes 16 2 intended to allow longitudinal positioning, that is to say in the direction of the optical axis, of the support 4 relative to at the turntable 16.

La figure 3 est une vue en élévation du module de la figure 1. La figure 4 est une représentation en coupe suivant l'axe IV-IV de la figure 3. On peut observer que le support 4 comprend plusieurs portions, en l'occurrence une portion arrière 41 en contact avec la platine 16 sur la portion arrière 61 du radiateur, une portion intermédiaire 42 et une portion avant 43 disposée au-dessus de la portion avant 62 du radiateur 6 et sur ses bossages 63.The figure 3 is an elevation view of the module of the figure 1 . The figure 4 is a representation in section along the axis IV-IV of the figure 3 . It can be observed that the support 4 comprises several portions, in this case a rear portion 4 1 in contact with the plate 16 on the rear portion 6 1 of the radiator, an intermediate portion 4 2 and a front portion 4 3 disposed above of the front portion 6 2 of the radiator 6 and on its bosses 6 3 .

On peut observer à la figure 4 que la lentille 8 comprend deux pattes de fixation 81 s'étendant depuis un bord inférieur vers les pattes 64 du radiateur 6. Plus précisément, ces pattes 81 s'étendent au travers d'ouvertures 24 dans la portion avant 43 du support 4. Ces pattes 81 peuvent comprendre des cavités, ou des passages traversant, chaussant les extrémités des pattes 64. Comme on peut l'observer à la figure 4, la portion avant 43 du support 4 est, sur sa face inférieure, en appui sur les bossages 63 et, sur sa face supérieure, en appui sur la lentille 8. La portion avant 43 est ainsi positionnée verticalement de manière exacte par rapport au radiateur 6 ainsi qu'à la lentille 8.We can observe at figure 4 that the lens 8 comprises two fastening tabs 8 1 extending from a lower edge to the lugs 6 4 of the radiator 6. More specifically, these lugs 8 1 extend through openings 24 in the front portion 4 3 of the support 4. These lugs 8 1 may comprise cavities, or through passages, fitting the ends of the lugs 6 4 . As can be seen at figure 4 , The front portion 4 3 of the support 4 is, on its underside, bearing on the bosses 3 and 6, on its upper face bears against the lens 8. The front portion 4 3 is thus vertically positioned accurately by relative to the radiator 6 as well as to the lens 8.

L'engagement entre les pattes 64 du radiateur 6 et les orifices ou cavités des pattes de fixation 81 de la lentille 8 est préférentiellement sans jeu, plus particulièrement avec un serrage. En référence à la figure 2, on peut observer que les pattes 64 du radiateur 6 peuvent présenter à leurs extrémités des nervures longitudinales destinées à assurer un léger serrage avec les pattes de fixation 81 de la lentille. Le matériau de la lentille étant préférentiellement un matériau plastique translucide ou transparent, tel que par exemple du polycarbonate, les pattes de fixation 81 peuvent se déformer quelque peu lors de leur mise en place sur les pattes 64, afin d'éviter tout jeu mécanique et incertitude quant au positionnement vertical de la lentille.The engagement between the legs 6 4 of the radiator 6 and the holes or cavities of the fastening tabs 8 1 of the lens 8 is preferably without play, more particularly with a clamping. With reference to the figure 2 it can be seen that the tabs 6 4 of the radiator 6 may have at their ends longitudinal ribs intended to ensure a slight tightening with the fastening tabs 8 1 of the lens. The lens material preferably being a translucent or transparent plastic material, such as for example polycarbonate, the 8 1 Fixing legs can deform somewhat when they are placed on the legs 6 4 , to avoid any mechanical play and uncertainty as to the vertical positioning of the lens.

En ce qui concerne le positionnement longitudinal de la lentille 8, on peut observer à la figure 4, ainsi qu'à la figure 2, que les pattes 64 forment un profil en S, c'est-à-dire un profil avec un ressaut, ce ressaut formant une surface de butée dans la direction longitudinale du module. Le positionnement longitudinal des pattes de fixation 81 de la lentille 8 est ainsi également assuré.With regard to the longitudinal positioning of the lens 8, it can be seen at figure 4 , as well as figure 2 , that the tabs 6 4 form an S profile, that is to say a profile with a projection, this projection forming a stop surface in the longitudinal direction of the module. The longitudinal positioning of the fastening tabs 8 1 of the lens 8 is thus also ensured.

Toujours à la figure 4, on peut observer que la plieuse, plus précisément sa portion centrale et optiquement active 141 est en appui sur une nervure 66 du radiateur, qui va être davantage détaillée en relation avec les figures 5 et 6.Always at the figure 4 , One can observe that the folding machine, more precisely its central portion and optically active 14 1 is supported on a rib 6 6 of the radiator, which will be detailed further in connection with the figures 5 and 6 .

La figure 5 illustre le radiateur 6 du module de la figure 1, équipé uniquement de la lentille 8 et de la plieuse 14, cette dernière étant représentée en transparence. On peut observer que le radiateur comprend des nervures 66 en forme de H suivant la direction longitudinale du module. Ces nervures servent de surface d'appui à la plieuse 14. Il est en effet important que la plieuse 14, plus particulièrement sa portion centrale 141 réfléchissante, soit parallèle à la surface supérieure de la portion arrière 61 du radiateur 6. En effet, tout désalignement de la surface réfléchissante de la plieuse 14 est susceptible de modifier de manière sensible la photométrie du faisceau lumineux du module. Il est donc important de pouvoir positionner de manière précise la plieuse 14 non seulement en translation selon la direction longitudinale mais également verticalement et en rotation autour d'un axe transversal. Les nervures 66 assurent un positionnement vertical et en rotation autour d'un axe transversal de la plieuse 14. Elles permettent également d'éviter des fuites de lumière entre la face inférieure de la portion centrale 141 et la face supérieure de la portion arrière 61 du radiateur.The figure 5 illustrates the radiator 6 of the module of the figure 1 , equipped only with the lens 8 and the folder 14, the latter being represented in transparency. It can be seen that the radiator comprises ribs 6 6 in the shape of H in the longitudinal direction of the module. These ribs serve as a bearing surface for the folder 14. It is indeed important that the folder 14, more particularly its central portion 14 1 reflecting, is parallel to the upper surface of the rear portion 6 1 of the radiator 6. Indeed any misalignment of the reflective surface of the folder 14 is likely to significantly modify the photometry of the light beam of the module. It is therefore important to be able to accurately position the folder 14 not only in translation in the longitudinal direction but also vertically and in rotation about a transverse axis. The ribs 6 6 provide vertical and rotational positioning about a transverse axis of the folder 14. They also prevent light leakage between the underside of the central portion 14 1 and the upper face of the rear portion 6 1 of the radiator.

On peut également observer à la figure 5 que la portion arrière 61 du radiateur comprend deux cavités 67 dont la fonction sera détaillée en relation avec les figures 8 et 9.We can also observe at figure 5 that the rear portion 6 1 of the radiator comprises two cavities 6 7 whose function will be detailed in relation to the Figures 8 and 9 .

Des vis de fixation 20 et 22 de la platine supportant la source lumineuse et du support sont visibles à la figure 5.Fixing screws 20 and 22 of the plate supporting the light source and the support are visible at the figure 5 .

La figure 6 est une vue en coupe transversale du module de la figure 1, la coupe étant au niveau de la plieuse 14. Cette vue illustre le mode de fixation et de positionnement de la plieuse 14. On peut observer que la portion centrale 141 de la plieuse est bien en appui sur la nervure transversale 66 du radiateur 6. On peut également observer que les bras de fixation 142 de la plieuse coopèrent par engagement avec des orifices dans le support 4. Ces bras 142 peuvent comprendre à cet effet des languettes de retenue destinées à permettre l'insertion des bras 142 dans les orifices et d'empêcher leur sortie de ces orifices. D'autres moyens de fixation et/ou de retenue peuvent être envisagés.The figure 6 is a cross-sectional view of the module of the figure 1 , the section being at the level of the folder 14. This view illustrates the mode of fixing and positioning of the folder 14. It can be observed that the central portion 14 1 of the folder is in contact with the transverse rib 6 6 of the radiator 6. One can also observe that the fastening arms 14 2 of the brake cooperate by engagement with holes in the support 4. These arms 14 2 may include for this purpose retaining tabs intended to allow the insertion of the arms 14 2 in the orifices and to prevent their exit from these orifices. Other fixing and / or retaining means can be envisaged.

Les nervures 66 illustrées aux figures 5 et 6 sont préférentiellement venues de matière avec le radiateur 6. Ce dernier est préférentiellement en matériau métallique ou plastique apte à être moulé, comme par exemple de l'aluminium ou des thermoplastiques présentant des propriétés de conduction thermique. Il est donc intéressant de réaliser ces nervures directement lors de la réalisation du radiateur.The ribs 6 6 illustrated in FIGS. figures 5 and 6 are preferably integral with the radiator 6. The latter is preferably made of metal or plastic material capable of being molded, such as for example aluminum or thermoplastics having thermal conduction properties. It is therefore interesting to make these ribs directly during the realization of the radiator.

Il est à noter que la forme de ces nervures peut dévier de celle illustrée aux figures 5 et 6. En effet, elles pourraient par exemple comprendre deux nervures transversales parallèles et distantes l'une de l'autre. Elles pourraient également présenter un profil en forme de U ou encore en forme de rectangle. Il pourrait également s'agir de plusieurs bossages ponctuels.It should be noted that the shape of these ribs may deviate from that illustrated in figures 5 and 6 . Indeed, they could for example include two transverse ribs parallel and distant from each other. They could also have a U-shaped profile or in the form of a rectangle. It could also be several point bosses.

La figure 7 est une vue en élévation du module de la figure 1. A la différence de la figure 3, la figure 7 illustre le module pourvu des vis de fixation 20 et 22, visibles notamment à la figure 5. Comme on peut le voir à la figure 7, l'axe de coupe VIII-VIII passe par un trou oblong 45 du support 4 ainsi que par un des pions 65 du radiateur 6. La tête de la vis de fixation 22 traversant ce trou oblong est totalement reçue par ledit trou, signifiant que cette vis n'est pas en appui sur le support 4 mais bien uniquement sur la platine.The figure 7 is an elevation view of the module of the figure 1 . Unlike the figure 3 , the figure 7 illustrates the module provided with fixing screws 20 and 22, visible in particular at the figure 5 . As can be seen at figure 7 the cutting axis VIII-VIII passes through an oblong hole 4 5 of the support 4 as well as one of the pins 6 5 of the radiator 6. The head of the fastening screw 22 passing through this oblong hole is totally received by said hole, meaning that this screw is not supported on the support 4 but only on the plate.

La figure 8 est une représentation en coupe suivant l'axe VIII-VIII de la figure 7. La figure 9 est une vue en coupe VIII-VIII du module de la figure 7, la vue étant toutefois en perspective et le point de vue de la coupe étant opposé à celui de la figure 8.The figure 8 is a representation in section along the axis VIII-VIII of the figure 7 . The figure 9 is a sectional view VIII-VIII of the module of the figure 7 however, the view is in perspective and the point of view of the section opposite to that of the figure 8 .

On peut y observer que le support 4 comprend deux ergots 44, de part et d'autre de l'axe longitudinal ou optique du module. Chacun de ces ergots 44 s'étend depuis la portion arrière 41 du support vers une cavité 67, c'est-à-dire essentiellement verticalement vers le bas. Chacun des ergots 44 traverse également un trou oblong 162 pratiqué dans la platine 16 et est en appui dans la direction longitudinale contre le bord dudit trou. En l'occurrence, l'appui est dirigé vers l'arrière, c'est-à-dire que c'est la portion arrière du bord du trou oblong 162 qui est en contact avec l'ergot 44. Il est toutefois entendu qu'alternativement cet appui pourrait être dirigé vers l'avant.It can be seen that the support 4 comprises two lugs 4 4 , on either side of the longitudinal or optical axis of the module. Each of these pins 4 4 extends since the rear portion 4 1 of the support to a cavity 6 7 , that is to say substantially vertically downwards. Each of the lugs 4 4 also crosses an oblong hole 16 2 formed in the plate 16 and bears in the longitudinal direction against the edge of said hole. In this case, the support is directed rearward, that is to say that it is the rear portion of the edge of the oblong hole 16 2 which is in contact with the lug 4 4 . However, it is understood that alternatively this support could be directed forward.

Les cavités 67 peuvent être dimensionnées pour permettre aux ergots 44 de s'y déplacer librement lors du positionnement du support 4. A cet effet, la cavité peut s'étendre au-delà du bord du trou oblong 162 avec lequel l'ergot 44 vient en butée.The cavities 6 7 may be sized to allow the pins 4 4 move freely when positioning the holder 4. To this end, the cavity may extend beyond the edge of 16 2 slot with which the ergot 4 4 abuts.

La platine 16 est fixée par la vis 22 traversant le trou oblong 45 du support. La platine 16 peut être positionnée sur le radiateur 6 grâce aux deux pions 65 dudit radiateur qui coopèrent avec des orifices correspondants de la platine 16. Lors de la mise en place du support 4, après avoir positionné et éventuellement fixé la platine 16, la portion arrière 41 dudit support est déposée contre la platine 16 en veillant à ce que les ergots 44 pénètrent les trous oblongs 162 de la platine et les cavités correspondantes 67 du radiateur. Des trous oblongs 46 peuvent être prévus pour coopérer avec les pions 65 tout en permettant le déplacement du support 4. Lorsque la portion arrière 41 du support 4 est en contact avec la platine 16, le support 4 peut alors être déplacé essentiellement dans la direction longitudinale de manière à amener chacun des ergots 44 en contact avec le bord correspondant des trous oblongs 162 de la platine. Les vis de fixation 20 prenant appui sur le support peuvent ensuite être mises en place et serrées afin d'assurer la fixation du support 4 ainsi que de la platine 16 sur le radiateur 6.The plate 16 is fixed by the screw 22 through the oblong hole 4 5 of the support. The plate 16 can be positioned on the radiator 6 by means of two pins 5 of the radiator 6, which cooperate with corresponding holes in the plate 16. At the introduction of the support 4, after having positioned and optionally fixed the plate 16, the rear portion 4 1 of said support is deposited against the plate 16 by ensuring that the lugs 4 4 penetrate the oblong holes 16 2 of the plate and the corresponding cavities 6 7 of the radiator. 4 oblong holes 6 may be provided to cooperate with the pins on May 6 while allowing movement of the carrier 4. When the rear portion 4 1 of the holder 4 is in contact with the plate 16, the support 4 can then be moved essentially in the longitudinal direction so as to bring each of the lugs 4 4 in contact with the corresponding edge of the oblong holes 16 2 of the plate. The fixing screws 20 bearing on the support can then be put in place and tightened in order to secure the support 4 and the plate 16 on the radiator 6.

L'utilisation des ergots 44 en guise de moyens de butée selon la direction longitudinale agissant entre le support et la platine permet d'assurer un positionnement exact entre la surface réfléchissante 10, supportée par le support, et la source lumineuse.The use of the lugs 4 4 as stop means in the longitudinal direction acting between the support and the plate ensures exact positioning between the reflecting surface 10, supported by the support, and the light source.

Il est à noter que les ergots et les trous oblongs de la platine avec lesquelles ils coopèrent peuvent être conçus pour assurer un positionnement non seulement selon la direction longitudinale mais également selon la direction transversale, c'est-à-dire un positionnement dans le plan de glissement entre la platine et la portion arrière du support. A cet effet, le bord des trous oblongs et/ou l'ergot correspondant peut/peuvent être profilé(s) de manière à assurer un centrage de l'ergot correspondant.It should be noted that the pins and the oblong holes of the plate with which they cooperate can be designed to ensure positioning not only in the longitudinal direction but also in the transverse direction, that is to say a positioning in the plane sliding between the plate and the rear portion of the support. For this purpose, the edge of the oblong holes and / or the corresponding pin may / may be profiled (s) to ensure a centering of the corresponding lug.
