A lighting device for motor vehicles including at least one first light source that is centered on and/or aligned with the optical axis of a projection lens of the lighting device, and a diaphragm element in order to form a cut-off profile in a first light beam shaped by the projection lens. This advantageous configuration enables reduction of chromatic defects linked to interaction between the diaphragm element and light rays generated by the first light source. The lighting device advantageously includes a second light source in order to be able, in collaboration with the first light source, to generate a second light beam. In this case, the diaphragm element is advantageously inclined on the second light source side relative to the optical axis of the projection lens.

Motor vehicle lighting device

The invention proposes a lighting module for motor vehicles, which comprises optical means for deviating in angular manner at least a portion of the light rays passing through them, without thereby changing the geometry of the projection lens of the lighting module.

Lighting module with diffraction screen for a motor vehicle

A lighting module for a motor vehicle includes a first light source and a first collimator for generating a first light beam of 'low beam' type in collaboration with a first projection lens. Also included are second and a third light sources, the second light source collaborating with a second collimator to generate a first beam complementing the first light beam in order to form a second light beam of 'high beam' type. In order to reduce the visibility of a cut-off zone in the second beam, the third light source collaborates with a third collimator and/or a second projection lens in order to form a second complementary beam which at least partly overlaps the cut-off zone. A front headlight for a motor vehicle can include such a lighting module.

Lens for a lighting device of a motor vehicle includes a rear face designed to be oriented toward a light source of the lighting device, and a convex front face designed to be oriented toward the roadway being illuminated. The lens has a median vertical plane designed to be substantially orthogonal to the roadway, the front face having a first zone of diffusion with microstructures adapted to diffuse the light emitted by the light source, the first zone of diffusion extending in the median vertical plane. The front face furthermore includes at least two second zones of diffusion each one having microstructures adapted to diffuse the light emitted by the light source, the two second zones of diffusion being situated on either side of the median vertical plane. The microstructures of the two zones of diffusion have a depth absolutely greater than the depth of the microstructures of the first zone of diffusion.

Optical device for a motor vehicle

A headlamp for a motor vehicle, this headlamp comprising at least one optical module capable of emitting a plurality of light beams, including a low beam and at least one additional light beam. The optical module is equipped with a cover plate which can be moved between at least two positions, this movable cover plate being configured along a shaft mounted so as to rotate in the optical module and driven in rotation at least by a motor. The shaft comprises at least one first cut-off member configured as a double-edged cover plate providing an oblique cut-off for emission of the low beam, and at least one second cut-off member configured as a wall of substantially constant height, angularly offset relative to the first cut-off member and providing at least one substantially vertical cut-off line for emission of a high beam.

Optical module for a motor vehicle capable of selectively lighting a zone

A lighting and/or signaling device for a motor vehicle, comprising at least one light source emitting a light beam and at least one optical guide in which the light beam propagates, the optical guide comprising: a first face forming an exit face for the light beam, and a second face, opposite to the exit face, forming a reflection face for the light beam, such that the light guide is associated with a diffusing screen disposed opposite the reflection face of the light guide.

Lighting or signal device with an optical guide for a motor vehicle

A proposed method to illuminate optimally, or at least in an improved fashion compared with existing solutions, a road taken by a vehicle in question implementing the method whilst ensuring that other vehicles are not dazzled. To this end, it is not proposed in the invention to detect the distance between the vehicle in question and the first vehicle liable to be dazzled by the vehicle in question, and to generate accordingly a light beam optimized in terms of range on the road, and advantageously light intensity; according to the invention, the optimization of the light beam produced is achieved by the use of the motorway function available on the vehicle in question. The use of this function in this context also ensures a gradual transition between the function of the dipped type and the function of the main-beam type in the context of automatic switching operations between these functions.

Method for the automatic adaptation of a light beam of a headlight device

The invention concerns a lighting and/or signalling device for a motor vehicle comprising at least one light source emitting a light beam and at least one optical guide in which the light beam propagates, said optical guide comprising an output face for the light beam, and another reflection face, opposite to the output face, having a serrated profile forming a reflection face for the light beam, notably comprising a series of prisms, each prism forming, with the following prism (), a bottom angle (D). At least one bottom angle of the reflection face is truncated, and/or in that the output face has a profile comprising flutes.
