Definitions

  • the invention relates to a motor vehicle optical module, also called light module or lighting module.

  • the upper face 15 of the substrate 12 carries a series of five light sources 50 in the form of light-emitting diodes, as well as a resistor 52. These components 50 and 52 are soldered on the upper face 15 of the substrate which is for example a printed circuit board.

  • the wall 102 is a protective wall to avoid the so-called "sunburn” phenomenon. This phenomenon results, in certain situations, from the accidental penetration of the solar radiation inside the optical module by reflection on the reflecting front face 21 of the reflector 20, then through the collector 16 thereby causing a local heating phenomenon harmful to light emitting diodes 50, which may eventually lead to their destruction.
  • the wall 102 makes it possible to defocus the beam resulting from the solar radiation with respect to the support 18

  • the collector 16 can be indexed in position with a keying function, with respect to the substrate 14, to the support 18, and to the cooling block 12.
  • the precise indexing in position of the collector 16 relative to the substrate 14 is important to ensure proper positioning of the collector 16 with respect to the light emitting diodes 50.
  • the collector 16 comprises a series of light guides 91 each of which is delimited downwards by a facet 93 which constitutes the entrance surface in the collector 16 of the light emitted by the light emitting diode 50 arranged opposite the facet 93.
  • Each lateral block 92 is delimited upwards by a flat surface portion 96.
  • each lateral block 92 is housed inside a branch 79 of the support 18, and each flat surface portion 96 constitutes a bearing surface for a pin 77 associated which exerts a punctual support effort vertically downward to press the collector 16 bearing on the upper face 15 of the substrate 14.
  • Fixing and tightening of all the components 12, 14, 16 and 18 is effected by stacking these components with their indexing of relative positions, then by fixing by screwing by means of the rear fastening screws 38 and the front fixing screw 40.
  • the lug 70 Due to the elastically deformable design of the fixing lug 70, during the screwing and the axial tightening of the screw 40, the lug 70 is elastically deformed so as to exert permanently a clamping force to press each lateral block 92 of the collector 16 on the upper face 15 of the substrate 14.
  • the reflector is a plastic molded part which is indexed in position and which is fixed on the support 18, more precisely to the upper part of the rear plate 56 of the support 18.
  • the reflector 20 For its positioning and attachment to the support 18, the reflector 20 has a rear horizontal upper tab 86 which has three complementary indexing holes 86-B.
  • the indexing fingers 56-A are received in the indexing holes 86-B, and the fixing lug 56 is mounted pressing vertically on the bearing surface 84 by a fixing screw 88.
  • the reflector 20 is thus indexed in position on the support 18 and, indirectly, with respect to the collector 16.
