Abstract:
1. An optical system for generating, from a light source and along an optical axis (X-X), a composite lighting or signaling beam for a motor vehicle, said composite lighting or signaling beam comprising at least one central light beam and at least one peripheral light beam surrounding said at least one central light beam; and said optical system comprising an optical diffuser for distributing for distributing said composite light beam in a predetermined manner in a first plane (Y-Y, Z-Z) orthogonal to said optical axis (X-X); wherein said optical diffuser of the optical system is configured for generating, in a second plane (X-X; Z-Z) comprising said optical axis (X-X), said at least one central light beam and/or said at least one peripheral light beam surrounding said at least one central light beam in such a manner that light rays of said at least one central light beam and/or of said at least one peripheral light beam are inclined to provide an angular opening of at least 45°, on either side of said optical axis (X-X), with respect to said optical axis (X-X).
