Abstract: The present invention relates to a light emitting device having an optical part. The optical part comprises at least a first portion comprising a first light input face for receiving first light rays from a first light source and transmitting the first light rays directly toward a light output face so that the light exits the optical part. The optical part further comprises a second light input face for receiving second light rays light from a second light source and transmitting the second light rays toward said light output face so that they are reflected at least one time by total internal reflection on a first zone of said light output face before exiting the optical part through a second zone of said light output face.

Abstract: A lighting system for a motor vehicle comprising at least one primary optical device for emitting a light beam exhibiting a cutoff profile, the primary optical emission device comprising at least one light source and one single-piece primary optical member comprising an input surface suitable for receiving a light beam emitted by the light source, a ray interception surface configured to form the cutoff profile in the light beam received and an output surface for the light beam.
This system also comprises a projection device arranged downstream of the primary optical emission device(s) and comprising an input surface arranged facing the primary optical emission device(s), and through which are introduced rays of the light beam derived as output from the primary optical emission device(s) a single continuous output surface through which the light beam is projected.

Abstract: A motor-vehicle lighting device including a plurality of primary optical elements, intermediate lenses, and a curved projecting lens. Each primary optical element has a curved exit refracting surface and comprises a plurality of rectangular light guides that are each intended to interact with one light-emitting diode one laser. Each intermediate lens is placed between an exit refracting surface of the primary optical element and the projecting lens. Each intermediate lens is configured to distribute and concentrate the radiation issued from an exit refracting surface of the element over and onto the projecting lens. The lighting device is configured so as to project the diode radiation entering into the light guides and exiting via the projecting lens in the form of luminous pixels, or luminous strips, the light intensity of each of which is controlled despite the curvature of the projecting lens.

Abstract: An optical part includes a transparent or translucent block having first and second collimators that are intended to receive the beams of first and second light sources so that the beams enter into the block. The collimators are arranged in such a way that these sources may be positioned in a plane that an intermediate exit dioptric interface toward which the first collimator guides the first beam so that this first beam exits from the block through this intermediate dioptric interface. A cutoff dioptric interface forms a folder for the first beam and for the second beam, and the first collimator with the intermediate dioptric interface and the second collimator being arranged so that each beam converges on the cutoff edge of the folder.

Abstract: A luminous device including a first row of light sources for generating first unitary beams and a second row of light sources for generating second unitary beams. The first unitary beams have a sloped profile. The first unitary beams and second unitary beams are associated so as to construct a resultant beam provided with a slope and with a section extending laterally from the slope.
