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.
  • the folder is formed directly in the main room. Since this room is made of plastic, it is then necessary to apply a reflective coating on the area corresponding to the folder. This operation can be expensive.
  • the positioning of the folder is dependent on the manufacturing tolerances of the main part which can in certain circumstances be penalizing.
  • the main piece is also a complex piece whose realization is expensive.
  • 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 provide a lighting module whose realization is less expensive while ensuring accurate and easy relative positioning between the various components of the module in question, more particularly between the folder and the other elements as the light source and the reflecting surface disposed opposite said source.
  • 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 first reflective surface with a first and a second focus and able to reflect the rays of the light source or sources located at the first focus towards the second focus; a second reflective surface, called a bending surface, with a cutting edge located at the second focus; a lens adapted to deflect rays from the first and second reflective surfaces to form a light beam along an optical axis of the module; a heat sink adapted to dissipate the heat produced by said source or sources and supporting the folder; remarkable in that the heat sink comprises at least one boss directed upwards and in contact with the folder.
  • the first reflective surface may have a generally elliptical profile.
  • the contact or bosses with the folder ensures vertical positioning of said folder.
  • the boss or bosses extend or are distributed transversely to the optical axis over more than 50%, preferably more than 60% of the transverse dimension of the folder.
  • transverse to the optical axis is meant perpendicularly or obliquely to said axis.
  • the or at least one of the bosses extends transversely to the optical axis continuously over more than 50%, preferably more than 60% of the transverse dimension of the folder.
  • the boss or bosses comprise at least one rib transverse to the optical axis and / or at least one longitudinal rib.
  • the boss or bosses comprise at least one rib transverse to the optical axis and at least two longitudinal ribs distant from each other.
  • At least two longitudinal ribs each extend longitudinally from one or the other end of the transverse rib.
  • the boss or bosses comprise at least two ribs transverse to the optical axis. These transverse ribs make it possible to ensure stability of the folder with respect to pivoting along a transverse axis.
  • the transverse ribs are successively along the optical axis.
  • the boss or bosses comprise ribs forming a profile, in a generally horizontal plane and along the optical axis, in the form of H, U, reversed U, ⁇ or reversed ⁇ . , Y, C, or parallelogram.
  • the heat sink is made of metallic material and / or plastic, the boss or bosses and said dissipator being formed by the same piece.
  • the boss or bosses and heat sink are material
  • the boss or bosses and heat sink are made by molding, for example with the dissipator.
  • the boss or bosses may be a plastic part attached to the dissipator.
  • the folder extends mainly in a direction transverse to the optical axis.
  • the folder is a metal sheet whose cross section relative to the optical axis has a U-shaped profile.
  • the module comprises a support supporting the first reflecting surface and the folder.
  • the support and the first reflective surface are the same part, preferably made of material.
  • the support comprises positioning means with respect to the heat sink and in the direction of the optical axis, said means preferably cooperating with a plate supporting the light source or sources, said plate being arranged on the heatsink.
  • the lens is fixed directly to the heat sink, the support and the lens comprising contact means ensuring a relative positioning in the vertical direction.
  • the lateral portions of the folder corresponding to the branches of the U comprise means for fixing the support.
  • the heat sink comprises a rear portion supporting the light source or sources and a front portion downwardly of the rear portion, the boss or bosses being on the rear portion.
  • the heat sink has a stepped profile, the front portion forming a first step of said staircase and the rear portion forming a second step, higher, said staircase.
  • the boss or bosses are located on an area of the rear portion which extends from the front edge of the rear portion to less than 20% of the length of said portion.
  • At least a portion of the boss or bosses are adjacent to the front edge of the rear portion of the heat sink.
  • the support extends along the respective upper surfaces of the front and rear portions of the heat sink.
  • the boss or bosses have an average height of between 0.5 mm and 5 mm, preferably between 1 mm and 3 mm.
  • the invention also relates to a lighting device, especially for a motor vehicle, comprising a housing and at least one lighting module, remarkable in that the module or at least one of the modules is in accordance with the invention.
  • the measures of the invention are interesting in that they make it possible to easily and economically achieve a cut-off lighting module with precise positioning of the folder. This can be done from a portion of sheet metal.
  • 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 and comprises a reflecting surface 10.
  • the latter has a generally half-shell shape covering the light source 12.
  • the profile of the reflecting surface 10 may 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 different cutoff levels between the left and the right part of the illumination beam, in accordance with the regulations concerning vehicle lighting in effect 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 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 connector 6 1 serving may comprise one or more pins, namely two pins March 6 arranged to extend through corresponding holes in the plate 16. These pins may be generally conical.
  • the platen 16 also includes orifices 16 1 for receiving 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 the plate 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 material of the lens being preferably a translucent or transparent plastic material, such as for example polycarbonate, the fastening tabs 8 1 may be deformed somewhat when they are placed on the legs 6 4 , in order to avoid any play. mechanical and uncertainty as to 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 a stop surface in the direction longitudinal 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 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.
