  • This lighting module can be mounted in a motor vehicle headlamp. In this case, this module produces a cut-off lighting beam such as for a lighting function of the "dipped" type or even dipped beam.

  • 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 front edge located at the second focus.
  • the reflective surface 14 is commonly referred to as a “folder” insofar as it reflects part of the rays originating from the reflective surface 10 towards an upper part of the lens. Indeed, in the absence of the reflective surface 14, the rays passing behind the second focal point would encounter the lens at a lower part with a lower angle of incidence than those passing through the second focal point. These rays would then be deflected by the lens so as to form the upper part of the lighting beam. The fact of returning these rays towards 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 in the beam.

  • the figure 2 illustrates the heatsink 6 of the module of the figure 1 , the radiator being equipped only with the folder 14 and the platen 16. It can be observed that the radiator 6 comprises a rear portion 6 1 supporting the platen and a front portion 6 2 .
  • the front portion 6 2 is at a level lower than that of 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, higher than the first.
  • the folder 14 is located essentially at the level of the front edge of the rear portion 6 1 . More specifically, the folder 14 comprises a reflective central portion 14 1 and two lateral portions 14 2 in the form of arms for fixing to the support 4 ( figure 1 ). This fixing will be further detailed in relation to the figure 6 .
  • the folder 14 thus has a U-shaped transverse profile where only the central portion 14 1 is optically active.
  • the folder can be made from a portion of sheet metal, by shaping, bending 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 relation to the figures 3 and 4 . These bosses may be more numerous. It could also be one or more bosses extending transversely, like a rib.
  • 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 connection with the figures 3 and 4 .
  • the rear portion 6 1 can comprise one or more studs, in this case two studs 6 3 intended to pass through corresponding orifices of the plate 16. These studs can be generally conical.
  • the plate 16 also comprises orifices 16 1 intended to receive fixing screws and oblong holes 16 2 intended to allow longitudinal positioning, that is to say along the direction of the optical axis, of the support 4 with respect to to deck 16.
  • the picture 3 is an elevation view of the module of the figure 1 .
  • the figure 4 is a sectional representation along the IV-IV axis of the picture 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 arranged above the front portion 6 2 of the radiator 6 and on its bosses 6 3 .
  • the lens 8 comprises two fixing lugs 8 1 extending from a lower edge towards the lugs 6 4 of the radiator 6. More precisely, these lugs 8 1 extend through openings 24 in the front portion 4 3 of the support 4. These lugs 8 1 can comprise cavities, or through passages, fitting the ends of the lugs 6 4 .
  • the front portion 43 of the support 4 is, on its lower face, resting on the bosses 63 and, on its upper face, resting on the lens 8. The front portion 43 is thus positioned vertically in an exact manner by in relation to the radiator 6 as well as to the lens 8.
  • the engagement between the lugs 6 4 of the radiator 6 and the orifices or cavities of the fixing lugs 8 1 of the lens 8 is preferably without play, more particularly with a clamp.
  • the lugs 6 4 of the radiator 6 may have at their ends longitudinal ribs intended to ensure a slight tightening with the fixing lugs 8 1 of the lens.
  • the material of the lens preferably being a translucent or transparent plastic material, such as for example polycarbonate, the fixing lugs 8 1 can deform somewhat when they are put in place on the lugs 6 4 , in order to avoid any play mechanics and uncertainty about the vertical positioning of the lens.
  • the legs 6 4 form an S profile, that is to say a profile with a projection, this projection forming an abutment surface in the longitudinal direction of the module.
  • the longitudinal positioning of the fixing lugs 8 1 of the lens 8 is thus also ensured.
  • the figure 5 illustrates the heatsink 6 of the module of the figure 1 , equipped only with the lens 8 and the folder 14, the latter being shown in transparency.
  • the radiator comprises H-shaped ribs 66 in the longitudinal direction of the module. These ribs serve as a support surface for the folder 14. It is indeed important that the folder 14, more particularly its reflecting central portion 14 1 , 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 bender 14 is likely to significantly modify the photometry of the light beam of the module. It is therefore important to be able to precisely position the folder 14 not only in translation in the longitudinal direction but also vertically and in rotation around a transverse axis.
  • the ribs 6 6 ensure a vertical positioning and in rotation around a transverse axis of the folder 14. They also make it possible to avoid light leaks between the lower face of the central portion 14 1 and the upper face of the rear portion 6 1 from the radiator.
  • 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 .
  • Fixing screws 20 and 22 of the plate supporting the light source and of the support are visible on the figure 5 .
  • 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 attachment 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. It can also be observed that the fixing arms 14 2 of the folder cooperate by engagement with orifices in the support 4. These arms 14 2 can comprise for this purpose retaining tabs intended to allow the insertion of the arms 14 2 into the orifices and to prevent them from coming out of these orifices. Other fixing and/or retaining means can be envisaged.
  • the ribs 6 6 shown in figure 5 and 6 are preferably made in one piece 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 with thermal conduction properties. It is therefore advantageous to produce these ribs directly during the production of the radiator.
  • these ribs may deviate from that illustrated in figure 5 and 6 . Indeed, they could for example comprise two transverse ribs parallel and distant from each other. They could also have a U-shaped profile or else a rectangle shape. It could also be several point bumps.
  • the figure 7 is an elevation view of the module of the figure 1 . Unlike the picture 3 , the figure 7 illustrates the module provided with fixing screws 20 and 22, visible in particular at figure 5 . As can be seen at the figure 7 , the cutting axis VIII-VIII passes through an oblong hole 45 of the support 4 as well as through one of the pins 65 of the radiator 6. The head of the fixing screw 22 passing through this oblong hole is completely received by the said hole, meaning that this screw is not resting on the support 4 but only on the plate.
  • the figure 8 is a sectional representation along the VIII-VIII axis of the figure 7 .
  • the figure 9 is an VIII-VIII sectional view of the module of the figure 7 , the view being however in perspective and the point of view of the section being opposite to that of the figure 8 .
  • the support 4 comprises two lugs 4 4 , on either side of the longitudinal or optical axis of the module.
  • Each of these lugs 44 extends from the rear portion 41 of the support towards a cavity 67 , that is to say essentially vertically downwards.
  • Each of the lugs 44 also passes through an oblong hole 162 made in the plate 16 and bears in the longitudinal direction against the edge of said hole.
  • the support is directed towards the rear, 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 . It is however understood that alternatively this support could be directed forwards.
  • the cavities 67 can be dimensioned to allow the lugs 44 to move freely therein during the positioning of the support 4.
  • the cavity can extend beyond the edge of the oblong hole 162 with which the lug 4 4 comes into abutment.
  • the plate 16 is fixed by the screw 22 passing through the oblong hole 45 of the support.
  • the plate 16 can be positioned on the radiator 6 thanks to the two pins 65 of the said radiator which cooperate with corresponding orifices of the plate 16.
  • the rear portion 4 1 of the said support is placed against the plate 16, ensuring that the lugs 4 4 penetrate the oblong holes 16 2 of the plate and the corresponding cavities 6 7 from the radiator.
  • Oblong holes 46 can be provided to cooperate with the pins 65 while allowing the movement of the support 4.
  • the support 4 When the rear portion 41 of the support 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 into contact with the corresponding edge of the oblong holes 16 2 of the plate.
  • the fixing screws 20 resting on the support can then be put in place and tightened in order to ensure the fixing of the support 4 as well as the plate 16 on 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 automotive lighting. The invention relates to a headlamp 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'œillets 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. En effet, la lentille est totalement supportée par la pièce principale. Dans le cas de lentilles volumineuses et lourdes, cela peut poser quelques difficultés en termes de stabilité de la lentille notamment en présence de vibrations. De plus, la pièce principale est une pièce compliquée qui peut par ailleurs présenter certaines tolérances fabrication nuisant potentiellement à la précision de l'assemblage.The published patent document EP 2 428 725 A2 discloses an automotive headlamp lighting module. The lighting module in question comprises a light source of the light-emitting diode (LED) type mounted on a plate arranged on a cooling radiator of said diode. The module also comprises a first reflecting surface in the form of a half-shell and able to reflect the rays emitted by the light source towards a second reflecting surface, called a folding surface, with an edge for cutting off the lighting beam. The lighting module also includes a lens disposed in front of the second reflective surface. The rays reflected by the first reflecting surface and which pass in front of the cutting edge of the pile encounter the lens and are deflected by the latter. The rays encountering the second reflecting surface, instead of encountering the lens at its lower part with a lower angle of incidence than the preceding rays, are reflected towards the upper part of the lens with an essentially identical angle of incidence. These rays are then deflected by the lens towards the bottom of the beam instead of being deflected upwards, thus producing a cut-off typical of a lighting beam of the "dipped" type or even dipped beam. In this module, a main part serves as a support for the lens, the reflective surface in the form of a half-shell and the bender. This part 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 takes place by means of eyelets on the main part cooperating by engagement with barrels on the radiator. Fixing screws are then screwed into the barrels to secure the main piece to the radiator. The main part comprises abutment surfaces cooperating directly with the radiator with a view to its vertical positioning. This teaching is interesting in that the main part makes it possible to ensure precise relative positioning between the lens, the reflecting surface, the bender and the radiator. Indeed, the lens is fully supported by the main part. In the case of bulky and heavy lenses, this can pose some difficulties in terms of stability of the lens, particularly in the presence of vibrations. In addition, the main part is a complicated part which may moreover have certain manufacturing tolerances potentially detrimental to the precision of the assembly.

L'invention a pour objectif de pallier au moins un des inconvénients de l'art antérieur, plus particulièrement de l'art antérieur susmentionné. Plus particulièrement, l'invention a pour objectif de proposer un module d'éclairage dont la mise en œuvre soit simplifiée tout en conservant un niveau de précision important entre la lentille et le reste du module, comme notamment la surface réfléchissante et la ou les sources lumineuses.The object of the invention is to overcome at least one of the drawbacks of the prior art, more particularly of the aforementioned prior art. More particularly, the aim of the invention is to propose a lighting module whose implementation is simplified while maintaining a high level of precision between the lens and the rest of the module, such as in particular the reflecting surface and the source(s). bright.

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 representation in perspective of a lighting module according to the invention. This lighting module can be mounted in a motor vehicle headlamp. In this case, this module produces a cut-off lighting beam such as for a lighting function of the "dipped" 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 et 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 shown in figure 1 essentially comprises a radiator, or heat sink, 6 on which is arranged a plate 16 provided with one or more light sources 12, preferably of the light-emitting diode type. A support 4 represented in transparency and extending over the entire length of the module is arranged on the radiator 6. The support is in contact with a lens 8 and it comprises a reflecting surface 10. The latter has the general shape of a half-shell covering the light source 12. The profile of the reflective surface 10 may be generally elliptical with two focal points. 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 front edge located at the second focus. The reflective surface 14 is commonly referred to as a “folder” insofar as it reflects part of the rays originating from the reflective surface 10 towards an upper part of the lens. Indeed, in the absence of the reflective surface 14, the rays passing behind the second focal point would encounter the lens at a lower part with a lower angle of incidence than those passing through the second focal point. These rays would then be deflected by the lens so as to form the upper part of the lighting beam. The fact of returning these rays towards 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 in the beam. It can also be observed that the reflective surface of the bender 14 forms a projection in its middle so as to form two different cut-off levels between the left part and the right part of the lighting beam, in accordance with the regulations in terms of vehicle lighting in force in most countries. The use of a bender to form a cut-off light beam is well known per se to those skilled in the art.

Le faisceau d'éclairage est suivant une direction principale couramment appelée 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.One can also observe at the figure 1 that the plate 16 comprises at its rear part a connector 18 for its connection to the electrical harness of the headlight and of 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 heatsink 6 of the module of the figure 1 , the radiator being equipped only with the folder 14 and the platen 16. It can be observed that the radiator 6 comprises a rear portion 6 1 supporting the platen and a front portion 6 2 . The front portion 6 2 is at a level lower than that of 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, higher 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 level of the front edge of the rear portion 6 1 . More specifically, the folder 14 comprises a reflective central portion 14 1 and two lateral portions 14 2 in the form of arms for fixing to the support 4 ( figure 1 ). This fixing will be further detailed in relation to the figure 6 . The folder 14 thus has a U-shaped transverse profile where only the central portion 14 1 is optically active. The folder can be made from a portion of sheet metal, by shaping, bending 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 relation to the figures 3 and 4 . These bosses may be more numerous. It could also be one or more bosses extending transversely, like 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 connection with 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 is visible at the picture 2 , the rear portion 6 1 can comprise one or more studs, in this case two studs 6 3 intended to pass through corresponding orifices of the plate 16. These studs can be generally conical. The plate 16 also comprises orifices 16 1 intended to receive fixing screws and oblong holes 16 2 intended to allow longitudinal positioning, that is to say along the direction of the optical axis, of the support 4 with respect to to deck 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 picture 3 is an elevation view of the module of the figure 1 . The figure 4 is a sectional representation along the IV-IV axis of the picture 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 arranged above 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.One can observe at the figure 4 that the lens 8 comprises two fixing lugs 8 1 extending from a lower edge towards the lugs 6 4 of the radiator 6. More precisely, these lugs 8 1 extend through openings 24 in the front portion 4 3 of the support 4. These lugs 8 1 can comprise cavities, or through passages, fitting the ends of the lugs 6 4 . As can be observed at the figure 4 , the front portion 43 of the support 4 is, on its lower face, resting on the bosses 63 and, on its upper face, resting on the lens 8. The front portion 43 is thus positioned vertically in an exact manner by in relation 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 lugs 6 4 of the radiator 6 and the orifices or cavities of the fixing lugs 8 1 of the lens 8 is preferably without play, more particularly with a clamp. With reference to the figure 2 , it can be observed that the lugs 6 4 of the radiator 6 may have at their ends longitudinal ribs intended to ensure a slight tightening with the fixing lugs 8 1 of the lens. The material of the lens preferably being a translucent or transparent plastic material, such as for example polycarbonate, the fixing lugs 8 1 can deform somewhat when they are put in place on the lugs 6 4 , in order to avoid any play mechanics and uncertainty about 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.As regards the longitudinal positioning of the lens 8, one can observe at the figure 4 , as well as the figure 2 , that the legs 6 4 form an S profile, that is to say a profile with a projection, this projection forming an abutment surface in the longitudinal direction of the module. The longitudinal positioning of the fixing lugs 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 , it can be observed that the folder, more precisely its central and optically active portion 14 1 is supported on a rib 6 6 of the radiator, which will be further detailed in relation to the figure 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 heatsink 6 of the module of the figure 1 , equipped only with the lens 8 and the folder 14, the latter being shown in transparency. It can be observed that the radiator comprises H-shaped ribs 66 in the longitudinal direction of the module. These ribs serve as a support surface for the folder 14. It is indeed important that the folder 14, more particularly its reflecting central portion 14 1 , 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 bender 14 is likely to significantly modify the photometry of the light beam of the module. It is therefore important to be able to precisely position the folder 14 not only in translation in the longitudinal direction but also vertically and in rotation around a transverse axis. The ribs 6 6 ensure a vertical positioning and in rotation around a transverse axis of the folder 14. They also make it possible to avoid light leaks between the lower face of the central portion 14 1 and the upper face of the rear portion 6 1 from 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.One can also observe at the 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 of the support are visible on 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 attachment 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. It can also be observed that the fixing arms 14 2 of the folder cooperate by engagement with orifices in the support 4. These arms 14 2 can comprise for this purpose retaining tabs intended to allow the insertion of the arms 14 2 into the orifices and to prevent them from coming out of 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 shown in figure 5 and 6 are preferably made in one piece 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 with thermal conduction properties. It is therefore advantageous to produce these ribs directly during the production 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 figure 5 and 6 . Indeed, they could for example comprise two transverse ribs parallel and distant from each other. They could also have a U-shaped profile or else a rectangle shape. It could also be several point bumps.

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 picture 3 , the figure 7 illustrates the module provided with fixing screws 20 and 22, visible in particular at figure 5 . As can be seen at the figure 7 , the cutting axis VIII-VIII passes through an oblong hole 45 of the support 4 as well as through one of the pins 65 of the radiator 6. The head of the fixing screw 22 passing through this oblong hole is completely received by the said hole, meaning that this screw is not resting 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 sectional representation along the VIII-VIII axis of the figure 7 . The figure 9 is an VIII-VIII sectional view of the module of the figure 7 , the view being however in perspective and the point of view of the section being 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 observed there that the support 4 comprises two lugs 4 4 , on either side of the longitudinal or optical axis of the module. Each of these lugs 44 extends from the rear portion 41 of the support towards a cavity 67 , that is to say essentially vertically downwards. Each of the lugs 44 also passes through an oblong hole 162 made in the plate 16 and bears in the longitudinal direction against the edge of said hole. In this case, the support is directed towards the rear, 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 . It is however understood that alternatively this support could be directed forwards.

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 67 can be dimensioned to allow the lugs 44 to move freely therein during the positioning of the support 4. For this purpose, the cavity can extend beyond the edge of the oblong hole 162 with which the lug 4 4 comes into abutment.

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 passing through the oblong hole 45 of the support. The plate 16 can be positioned on the radiator 6 thanks to the two pins 65 of the said radiator which cooperate with corresponding orifices of the plate 16. When setting place of the support 4, after having positioned and possibly fixed the plate 16, the rear portion 4 1 of the said support is placed against the plate 16, ensuring that the lugs 4 4 penetrate the oblong holes 16 2 of the plate and the corresponding cavities 6 7 from the radiator. Oblong holes 46 can be provided to cooperate with the pins 65 while allowing the movement of the support 4. When the rear portion 41 of the support 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 into contact with the corresponding edge of the oblong holes 16 2 of the plate. The fixing screws 20 resting on the support can then be put in place and tightened in order to ensure the fixing of the support 4 as well as 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 44 as abutment means in the longitudinal direction acting between the support and the plate makes it possible to ensure 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 lugs 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 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 lug may/may be profiled so as to ensure centering of the corresponding lug.
