Definitions

  • the present invention relates generally to projectors for a motor vehicle. It relates more particularly to a lighting module adapted to equip these projectors and which comprises a light source, an elliptical collector which allows the reflection of a beam from this source and a convergent lens towards which the beam is reflected to be distributed and projected outside the projector, in front of the vehicle.
  • the light source is disposed substantially at the first focus of the collector.
  • Such modules are known comprising a light source, a collector, and a convergent lens, in which, in order to meet the standards intended for example to avoid dazzling oncoming road users, a beam of light is produced.
  • switch type lighting. Cut-beam is understood to mean a lighting beam that has a directional limit, the cutoff, above which the light intensity is reduced.
  • the document FR 2 753 148 A1 shows such a module.
  • such a cover is placed in position in the module by the cooperation of indexing holes formed in the cover and indexing pins integral with a component of the module, and it is fixed by screwing. It is then necessary to ensure during manufacture of the cache a good positioning accuracy of the indexing holes relative to the cutting edge. Furthermore, the assembly clearance that results from this type of assembly can hinder the precise positioning of the cutoff edge of the cache in the module. This results in less precision on the cutoff of the light beam at the output of the module. This degraded positioning generates, among other things, chromaticism.
  • the present invention proposes a lighting module in which the cache and the module in which it is implanted have the structures adapted to the most precise assembly possible.
  • the light source, the collector and the cover are mounted on an active surface of a support.
  • This support has a referencing wall which projects from said active surface and which serves as a reference for the positioning of the cache which is sought to be placed very precisely with respect to the second focus of the collector in the vicinity.
  • the module further comprises means for plating the cover against the support which are adapted to push the front face of said cover, which comprises said cutting edge, against said referencing wall.
  • the front face of the cover comprises a bearing zone adapted to come into contact with the referencing wall under the effect of the thrust of the plating means and a distinct zone carrying the cutting edge.

  • the ramp means are then inclined relative to the normal to the active surface and are oriented towards the referencing wall.
  • the cover slides towards the referencing wall and it is ensured that the front face, opposite the actuating part, comes close against the latter.
  • the ramp means are formed by two ramps which extend at a transverse distance from one another projecting from the support and in the same time, the cover has a form of plate provided with two tabs which extend the cover opposite its front face, each tab being adapted to cooperate with one of the ramps.
  • These ramps may comprise end walls projecting from the slope which serve as an abutment to the tabs of the cover.
  • the support comprises a rib which extends projecting transversely between the two ramps and on which the cover rests so as to avoid the passage of light beam between the cover and the support.
  • the cover has a reflecting face which is turned away from the active surface of the support.
  • the light beam can reflect completely on this face of the cache. It is on the opposite side to this reflecting face that the folding primer is made.
  • the reference wall of the support serves as a common reference to the cache and the collector.
  • the module may then comprise complementary second plating means adapted to force the collector in axial displacement against the referencing wall of the support.
  • second plating means may consist of a protrusion integral with the collector which is adapted to deform against a wall of the support by opposing a reaction force which generates the displacement of the collector opposite said wall, in the direction of the wall. SEO. This protrusion will be dimensioned so as not to create excessive deformation of the collector during its assembly.
  • the module may further comprise means for guiding the collector with respect to the support.
  • the cover has an axial position.
  • the active surface of the support is arranged so that the cover is disposed in the focal plane passing through the two homes when it is pressed against the active surface.
  • the optical element may be a convergent lens, or a complementary reflector, for example of parabolic shape, prolonging the reflection of light.
  • the invention also aims to protect a mounting method of a lighting module.
  • the light source is first fixed on the active surface of the support, then the cover is placed on the active surface on the one hand by positioning the front face of the cover against the reference wall, and a by placing the opposite part of the cover on ramp means which project from the support.
  • the cover is then inclined with respect to the active surface.
  • the collector is then reported on this active surface of the support by cooperating on the one hand complementary guiding means for transverse guiding of the collector relative to the support and secondly second plating means for pushing the collector against the wall SEO support.
  • the cover is deformed so that the sealing portion is pressed against the active surface by internal ribs of the collector and the actuating portion is pressed against the ramp means.
  • the inclined shape of the ramp means on which the actuating portion rests generates the plating of the cover against the wall of the SEO. It remains then to screw the collector on the support when the collector is in abutment, thus trapping the cover between the internal ribs of the collector and the active surface of the support.
