Abstract: A light guide for a lighting and/or signaling device of an automobile vehicle comprising an entry face, a coupler, a main reflection face, and an exit face. The light guide is arranged in such a manner that, when a light source is disposed at a predetermined point with respect to the light guide, the entry face transmits the light from the light source to the coupler and the coupler transmits a part of this light to the main reflection face which directs it, in the form of a beam of parallel rays, directly or indirectly, toward the exit face in a direction forming an angle of 5° at the most with respect to the optical axis of the light guide.

Abstract: An optical waveguide for the propagation of a light beam adapted to travel by successive total reflections off the faces of the waveguide to an output face where the light beam is refracted. One of the faces of the waveguide forms, facing towards the output face, a support face for a pattern extending across the main direction of the beam to divert same towards the output face. According to a characterizing feature of the invention, the pattern is a bifunctional reflective pattern that is integral with the support face, having three portions including end portions formed by cone portions between which there is interposed an intermediate portion that comprises two facets that meet at a top edge, which is not parallel to the support face for the patterns.
