Definitions

  • the present invention relates to the field of light devices, in particular for motor vehicles.
  • optical modules making it possible, by means of a tilting cover, to perform a dipped beam or high beam function with the same light source and the same optical module.
  • such modules require at least one actuator and one specific mechanical device.
  • DRL Day Running Light
  • the document FR3039883 describes a light module comprising a block of transparent or translucent material receiving several light beams and deflecting them so as to form, at the output of this block, a cut-off lighting beam.
  • a light device equipped with such a light module must therefore be equipped with an additional light module to additionally produce a signaling beam, in particular a DRL.
  • a light device containing these modules and therefore a vehicle equipped with this light device, has two distinct light signatures depending on whether they operate by day, with the lighting function, or at night, with the DRL.
  • the technical problem which the invention aims to solve is therefore to produce an optical means for a luminous device, making it possible to reduce the size of said device and to carry out different luminous functions having the same luminous signature, and this without the need for mechanical means of transition from one function to another.
  • the cut-off member is arranged so as to stop or reflect at least some of the rays reaching it from one side or the other.
  • the first collimator is arranged so as to send the first light beam only on one side of the switching device, while the second collimator is arranged so as to send the second light beam on both sides of the switching device.
  • the projection system, the first collimator, the second collimator and the cut-off member are arranged so as to project the first beam into a cut-off beam and to project the second beam into a cut-off beam.
  • a cut-off beam and a non-cut-off beam can be projected from the same projection system.
  • the cut-off beam can be a passing beam while the uncut beam can be a signaling beam. Consequently, the beams having different light functions have the same light signature. In other words, said beams, on leaving the same exit surface, have an identical illuminated appearance.
  • the cut-off beam can be a dipped beam and the uncut beam can be a DRL, thus making it possible to obtain the same light signature day and night.
  • the optical unit according to the invention has a projection system for two separate collimators.
  • the optical unit occupies less space in the light device which contains it. Consequently, the luminous device can have a reduced volume, therefore be more compact compared to the device of the state of the art.
  • the optical unit comprises a first optical part and a second optical part, the first optical part comprising the first collimator and the second optical part comprising the second collimator and the first optical part comprises a portion in relief and the second optical part comprises a recess having a shape substantially complementary to the shape of the raised portion of the first part so that the raised portion fits into the recess; thus, the optical unit, composed of the first optical part and the second optical part, becomes more compact.
  • the invention also relates to a light device for a motor vehicle, in particular a vehicle headlamp, comprising an optical unit according to the invention.
  • the light device also includes the light sources emitting the first and the second light beam. These light sources can in particular be light-emitting diodes, also called LEDs (for Light-Emitting Diode in English).

  • the internal face of the casing is coated with a metal layer.
  • the metal layer may be an aluminum layer deposited on the internal face of the case by an aluminating process.
  • the metal layer makes it possible to improve the homogeneity of the light beam generated by the optical unit, in particular of the signaling beam. Beam quality is improved.
  • the internal face of the box can be coated with a layer of white color, in particular with white paint, for the same result as a metallic layer.
  • the terms “front”, “rear”, “lower”, “upper”, “top”, “bottom”, “transverse”, “longitudinal”, “horizontal”, as well as their gender or number, refer to the direction of light emission out of the optical unit as it is intended to be positioned in the light device mounted in the vehicle.
  • the terms “upstream” and “downstream” refer to the direction of light propagation within the optical unit.
  • the vertical direction is represented by the Z axis illustrated on the figures 1 to 8 , 11 and 12 .
