Definitions

  • optical modules capable of generating a light beam.
  • Such optical modules find particular applications in lighting and / or signaling devices for a motor vehicle.
  • Motor vehicles are conventionally equipped with a signaling device.
  • the latter use a light source which, until recently, was made by means of an incandescent lamp.
  • a new light source technology replaces these incandescent lamps: they are light-emitting diodes commonly called LEDs of the English Light Emitting Diode.
  • the latter are able to provide a sufficient luminous performance for a lighting and / or signaling function and have the advantage of being of reduced size which offers new opportunities in the design of the projectors and / or lights in which they are integrated.
  • These light-emitting diodes used as a light source also have the advantage of reducing the power consumption compared to the same optical function provided by an incandescent lamp. It is therefore understood from the foregoing reasons why motor vehicle manufacturers are applicants for this new technology.
  • the object of the present invention is therefore to solve the disadvantages described above mainly by proposing a particular organization of an optical module generating a light beam emitted by a plurality of light-emitting diodes, the latter being housed in cavities so to make them invisible from outside the device, said cavities then being arranged to return the beam created by each light emitting diode.
  • a superposition of a collector of one unit by one of the reflectors of another unit makes it possible to form a compact, optically efficient and economically viable optical module.
  • the subject of the invention is therefore an optical module for a lighting and / or signaling device for a motor vehicle, capable of outputting a light beam along an optical axis, this optical module comprising at least a first and a second unit. , each unit comprising at least one collector, a reflector and a light source capable of emitting light rays, each unit being arranged so that at least a portion of these light rays is reflected by the collector towards the reflector, then by reflector so as to participate in the emission of the light beam output, the optical module being characterized in that the reflector of the second unit at least partially conceals the collector of the first unit, for an observer looking at the optical module according to the optical axis.
  • the collector of the first unit is placed under the reflector of the second unit in a direction of output of the light beam out of the optical module.
  • the reflector of the second unit overlaps the collector of the first unit.
  • the direction of emission of the light beam is along the optical axis towards the front of the module and that the direction of observation is therefore in the opposite direction to the direction of emission of light. the light, backwards.
  • the reflector of the second unit totally masks the collector of the first unit.
  • the second unit is substantially identical to the first unit.
  • the units are arranged successively and contiguously, one by one, that is to say one after the other.

  • the units according to the invention also extend in the same secant plane to the optical axis, preferably substantially perpendicular to the optical axis, substantially ranging from an interval of plus or minus 15 °, preferentially more or less 10 °, limits included, with respect to the perpendicular to the optical axis.
  • the collector of a unit defines a cavity, the light source of this unit being disposed in this cavity.
  • the units are arranged to return the light rays emitted by the light sources in a substantially identical direction.
  • At least one reflector has a substantially parabolic shape.
  • all the reflectors of the units constituting the optical module are of parabolic shape. It is understood here that the profile of a surface of the reflector forms a parabola.
  • At least one manifold has a substantially elliptical shape.
  • all the collectors of the units constituting the optical module are of elliptical shape.
  • the surfaces of the collectors each form an ellipse.
  • At least the reflector of the second unit and the collector of the first unit are formed on the same body, in particular monolithic, that is to say made of a holding.
  • other collectors and reflectors may be part of the unit body when it has more than two units.
  • all the reflectors and the collectors of the units are formed on the same body.
  • At least one reflector and / or a collector units are aluminized.
  • all the reflectors and collectors are aluminized.
  • the optical module comprises a transparent or translucent element arranged to form the light beam from the light rays emitted by the units.
  • the transparent element is able to diffuse the light rays emitted by the units.
  • Such an optical module may in particular comprise a support for carrying the light sources of the units.
  • the support and the units are arranged in such a way that the light sources are arranged in the cavities of the units.
  • the support comprises a printed circuit board on which the light sources are mounted.
  • the support comprises a cooling element of the light sources.
  • These light sources are light emitting diodes.
  • At least two of the diodes can emit light of different colors from each other.
  • At least one diode can emit from the same physical component beams of different colors depending on the appropriate control of the chosen photometric function.
  • This diode may for example be of the bi-chip or multi-chip type. It is thus possible to implement two distinct optical functions in the same lighting and / or signaling device.
  • the module according to the invention comprises at least one additional light source arranged on the support next to at least one unit.

  • the first collector 10 which borders the first cavity 9 is arranged, in particular by its elliptical surface, so that no light ray can emerge from the optical module 1 without having been reflected by the first reflector 8.
  • the module according to the invention is thus arranged to prevent any direct emission of the light source, such an emission degrading the homogeneity of the light beam.

  • This second reflector 13 has a two-dimensional shape which follows a profile of a parabola portion, in particular a half-parabola, so as to orient the light rays 2 in the same direction. It is advantageous that the direction of the light rays 2 reflected by the second reflector 13 is parallel to the direction taken by the light rays 2 directed by the first reflector 8. Nevertheless, the invention covers the situation where the second reflector 13 is arranged by relative to the first reflector 8 so that the direction of the light rays returned by one and the other is concurrent.
  • This second reflector 13 is treated so as to reflect a maximum of light rays 2. To do this, the second reflector 13 is covered by a mirror.
