  • Publication number: 20240084992
    Abstract: An illumination system of a motor vehicle includes a first lighting module that is able to emit a first light beam with an upper cut-off, a second lighting module that is able to emit a second, pixelated light beam, and a system for mechanically adjusting the vertical orientation of the first and second light beams. A controller is able to receive an emission instruction for a given lighting function and is designed to control the adjusting system in order to bring about a simultaneous modification of the vertical orientation of the first and second light beams on the basis of the instruction and to control the second lighting module to emit a second, pixelated light beam having predetermined characteristics on the basis of said instruction.

  • Patent number: 11572993
    Abstract: A light module for a motor vehicle headlamp comprising at least one pixelated light source, a plurality of electroluminescent emitters distributed into a plurality of pixels and capable of emitting light rays, a projection optic arranged to directly image, toward the outside of the light module, a light beam formed by said light rays emitted by said at least one light source. The light module is characterized by a mask arranged between the at least one light source and the projection optic in order to completely or partially prevent light rays originating from the light source from being reflected by regions arranged outside the plurality of electroluminescent emitters of the light source.

  • Patent number: 11370352
    Abstract: The present invention proposes a lighting device for a motor vehicle comprising a first module that projects a first pixelated high beam, a second module that projects a second pixelated writing beam onto the road, and a third module that projects a third low beam cut-off. The first, second and third modules are arranged such that the first and second beams overlap at least partially vertically; and the second and third beams overlap at least partially vertically.

  • Patent number: 11326752
    Abstract: The invention proposes a lighting device for a motor vehicle, including a first lighting module adapted to project a pixelized first beam with a first resolution and a second lighting module adapted to project a pixelized low beam type second beam with a second resolution lower than the first resolution, the first and second lighting modules being such that the first and second beams overlap vertically at least in part to form a global beam, the device including a control unit able to control selectively a plurality of pixels of the first and second beams so as to project a motif in the global beam.

  • Patent number: 11242973
    Abstract: The invention relates to a motor vehicle lighting device that includes a first module with at least one first pixelated electroluminescent light source where the first module can produce a first pixelated partial high beam (HB1) having a first resolution and a first horizontal angular amplitude; and includes a second module with a second pixelated electroluminescent light source where the second module can produce a second pixelated partial high beam (HB2) having an angular amplitude smaller than that of the first pixelated partial high beam (HB1) and a resolution greater than that of the first pixelated partial high beam (HB2); the pixelated electroluminescent light sources preferably being monolithic.
