Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 invention aims to promote the assembly of a lighting module for the sake of accurate and easy relative positioning between the various constituent elements of the module in question, more particularly between the optical surfaces such as the reflective surfaces and the light source (s).
  • the subject of the invention is a light module, in particular for lighting and / or signaling, for a motor vehicle, comprising: at least one light source; a turntable for supplying power to the light source (s); a heat sink supporting the plate and able to dissipate the heat produced by the light source or sources; a reflective surface capable of reflecting the rays of the light source or sources in order to form a light beam along an optical axis of the module; a support of the reflective surface on the heat sink; remarkable in that the support comprises positioning means cooperating with the plate.
  • the support of the reflective surface is carried by the dissipator. It thus ensures a mechanical connection between the reflecting surface and the dissipator.
  • the reflecting surface forms a half-shell and is preferably a surface of revolution.
  • the profile of the reflecting surface can be elliptical.
  • the reflective surface may be formed on a cavity of the support, for example by metallization of this cavity. If necessary the reflective surface and the support form a single piece, a portion of which is the reflective surface.
  • the light source or sources are semiconductor emitter chips, of the electroluminescence diode type.
  • the plate comprises a circuit board, preferably with a connector, said circuit being connected to the source or sources lights for their food.
  • the light source (s) may be mounted on the printed circuit board.
  • the light source or sources are mounted directly on the heat sink, the light source or sources being electrically connected to the printed circuit board, for example by bridging.
  • the printed circuit board can support a connector for the power supply of the light source.
  • the means for positioning the support are stop means in the direction of the optical axis of the module.
  • the positioning means are arranged laterally on either side of the optical axis.
  • the plate extends between the heat sink and the support. Still advantageously, the support is in contact with the plate.
  • the positioning means comprise at least one, preferably two lugs, each lug protruding from the support towards a cavity in the heat sink and passing through a hole in the plate.
  • the or at least one of the holes of the plate traversed (s) by the lug or pins is oblong in the direction of the optical axis.
  • the lug or each of the lugs is configured to come into contact with a portion of the edge of the hole of the plate through which it passes to allow the positioning of the reflective surface with respect to the light sources.
  • the cavity or each of the cavities is forward in the direction of the optical axis relative to the contact portion of the edge of the hole.
  • the plate extends transversely, on either side of the optical axis, beyond the reflecting surface.
  • the support comprises one or more generally flat surface portions in contact with the plate, the positioning means being located on this portion or these surface portions.
  • the or each of the contact surface portions of the support comprises a hole, preferably oblong in the direction of the optical axis, providing a clearance space for a plate fixing means, such as that a screw.
  • the or each of the contact surface portions of the support comprises a hole, preferably oblong in the direction of the optical axis, traversed by a pin of the heat sink serving as positioning means for the plate compared to the heatsink.
  • the pins of the heat sink have a generally conical profile and the plate comprises orifices adapted to cooperate with said pins with a radial clearance less than 0.5 mm, preferably less than 0.2 mm, more preferably less than 0.1 mm.
  • the game can be zero.
  • the heat sink comprises a rear portion supporting the plate and a front portion downwardly of the rear portion, the front portion supporting a lens configured to deflect the rays emitted by the light source or sources .
  • the lens can be configured to form a regulatory beam from a photometry point of view.
  • the module comprises fixing means between the lens and the heat sink, and the support cooperates by engagement with the lens.
  • the heat sink has a staircase profile, the front portion forming a first step of said staircase and the rear portion forming a second mark, higher, said staircase.
  • the support extends along the respective upper surfaces of front and rear portions of the heat sink, the lens being in vertical support on said support.
  • the support comprises at least one opening for holding the lens on the support.
  • the support including its positioning means, is in one piece, preferably made of plastic.
  • the reflecting surface has a generally elliptical profile with a first focus and a second focus, the light source (s) being at the first focus, and the module comprises a second reflecting surface, called a bending surface, with a beam cutting edge at the second focus, said folder being fixed to the support and bearing on the heat sink.
  • the invention also relates to a light device for a motor vehicle, comprising a housing and at least one light module, remarkable in that the module or at least one of the modules is in accordance with the invention.
  • the measurements of the invention are interesting in that they make it possible to easily and economically achieve precise relative positioning between the reflecting surface and the light source or sources. In addition, they allow precise positioning of the light source or sources, via their plate, relative to the heat sink.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the plate 16 comprises at its rear part a connector 18 for its connection to the electrical harness of the projector and the vehicle.
  • 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.
  • 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.
  • 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.
  • 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 .
  • 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.
  • 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 .
  • 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 .
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 the support are visible at 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 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.
  • 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.
  • 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.
  • 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. 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.
  • 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 .
  • 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.
  • 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 .
  • this support could be directed forward.
  • 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.
  • 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.
  • 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.
  • the support 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.
