Definitions

  • the present invention relates to a lighting or signaling device for a motor vehicle.
  • Such a device is for example known from the document EP 0 066 438 A1 .
  • the lighting devices mainly include the dipped beam, main beam, fog or daytime running lights
  • the signal lights mainly include the position lights, direction change indicator lights, brake indicator lights , reversing lights, rear fog lights.
  • Each function generally includes a light source, an optical system redirecting the light rays emitted by the source in a general direction of emission, and possibly a lens.
  • closing also called indicator, participating or not in the formation of the light beam, these various elements being arranged to provide a lighting or signaling beam whose geometric and photometric characteristics must be in accordance with different regulations.
  • the enclosure closing glass or indicator light is generally common to all the devices present in the same enclosure.
  • a compact lighting or signaling device is known from the state of the art, in particular from the document EP-A-1,746,339 .
  • Such a device is shown schematically in the figure 1 .
  • This device comprises at least one light source 10 such as a light emitting diode in association with an optical input system 12 which is capable of collimating the light rays emitted by the light emitting diode 10 into a beam of parallel rays 14 in the axis emission of the lighting or signaling beam 18.
  • An optical output system 16 is interposed on the path of the parallel beam 14 so as to deflect the light rays to form the regulatory lighting or signaling beam 18.
  • the optical output system is formed by an output diopter 16 which deflects the light rays by refraction.
  • Such a device has the advantage of being very compact compared to a device provided with a reflector.
  • the radial size of the device is here limited by the cross section of the beam of parallel rays 14.
  • regulatory beams having, in at least one axial plane, an angular opening greater than a limit angular opening.
  • the angular opening is defined as being the angle formed between the main axis of the regulatory beam and the envelope of the regulatory beam, in a determined axial plane.
  • the light beams having an angular opening greater than a limit angle, such as that of a reversing light, cannot physically be produced by the sole refraction of a beam of parallel rays.
  • the output diopter 16 has concave or convex patterns.
  • the angle of deflection by refraction depends on the angle formed between the incident ray and the normal to the local surface of the diopter.
  • the incident parallel light rays are no longer refracted by the output diopter 16, but they undergo total reflection.
  • the light rays thus reflected "leak" radially in a crown 20 around the regulatory light beam, leaving a dark area around the light beam.
  • the limiting angular opening "a0" depends on the refractive indices of the light propagation media located on either side of the diopter.
  • the invention provides a lighting or signaling device comprising all the features of claim 1
  • the device according to the invention comprises an intermediate optical system which is interposed on the path of the beam of parallel rays and which is shaped so as to transmit a beam of non-parallel rays to the output diopter in order to obtain a light beam of lighting or signaling having a large angular opening. More particularly, the intermediate optical system deflects the light rays in at least one first opening plane, and the output diopter accentuates the deflection of the light rays in said opening plane. This makes it possible to obtain much higher beam opening angles in the beam opening plane and in particular an angular opening greater than the limit angular opening.
  • this configuration makes it possible to produce a signaling device, where the signaling device is a reversing light.
  • FIG. 3 We have represented in figures 3 and 4 a lighting or signaling device produced in accordance with the present invention. This device is intended to be mounted on a motor vehicle.
  • Such a device comprises a light source 10, such as a light-emitting diode in the example shown.
  • the light rays emitted by this light source 10 are received by an optical input system 12.
  • the optical input system 12 is here a dioptric system which is formed by a collimating optical element 12, the focus of which is arranged in the vicinity immediate of the light source 10.
  • the light rays emerging from this collimating element therefore form a beam of parallel rays 14.
  • An exit diopter 16 is interposed on the path of the beam of parallel rays 14.
  • the exit diopter 16 thus forms a regulatory lighting or signaling harness 18.
  • the collimating element constituting the optical input system 12 can for example be produced by a converging lens, for example a Fresnel lens.
  • the collimating element constituting the optical input system 12 could for example be formed by a concave shape given to the face opposite the light source 10. It could also be formed by concentric circular grooves constituting a Fresnel lens, taking into account the refractive index of the material constituting the device.
  • the output diopter 16 generally extends in a transverse vertical plane which is orthogonal to the incident light rays of the beam of parallel rays 14, and which is orthogonal to the main axis of the lighting or signaling beam 18.

  • the output optical unit 22 is made of a material having a determined refractive index.
  • the incident light rays are capable of being deflected by refraction by the output diopter 16 at most by a limit angle "a0" relative to their incident direction. Beyond this limit angle "a0", the light rays are reflected by the output diopter 16.
  • the light source 10 and the output diopter 16 here define the longitudinal optical axis of the device.
  • the output diopter 16 includes one or more lenticular patterns, specific to satisfy the desired lighting or signaling function.

  • the intermediate optical system 24 is intended to deflect the rays parallel light beams of parallel rays 14 so as to transmit a transition light beam 26 of non-parallel rays towards the output diopter 16.

  • the vertical angular opening "a2" of the reversing light beam 18 in a longitudinal vertical plane is however less than or equal to the limit angle "a0", for example less than 40 °.
  • Such a vertical angular opening "a2" can be obtained without prior deviation of the parallel light rays by the intermediate optical system 24 in a vertical plane.
  • the intermediate optical system 24 is shaped so as to deflect the light rays from the beam of parallel rays 14 in a horizontal plane of opening, while the exit diopter 16 is shaped so as to accentuate the deflection of the light rays in said horizontal opening plane.
