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.

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: 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.
