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.

Abstract: The present invention relates to a lighting module for an automobile headlamp that is able to emit a cut-off light beam along a predetermined optical axis. The lighting module includes a light source for generating a beam and an optical element for receiving the beam generated by the light source and configured to form from this beam the cut-off light beam. The optical element has a collimator configured to receive the beam generated by the light source and to collimate this beam into a collimated beam. An optical coupler is configured to couple the collimated beam into a coupled beam in a lightguide. A cut-off means is disposed within the lightguide on the path of the rays of the coupled beam and configured to intercept a portion of the rays in the lightguide and to form a cut-off beam. At least one output face of the lightguide is configured to project the cut-off beam outside of the optical element, and the optical element is formed as a single part.
