Abstract: A lighting module for a motor vehicle, including a first lighting submodule with a light source that is able to form a first light beam, a second lighting submodule that is able to form a second light beam, a second projecting lens for projecting the second light beam, adjoining the first projecting lens, and an optical device configured to return, towards the second projecting lens, light rays coming directly from the light source of the first lighting submodule and passing in front of the reflective surface of the first lighting module so as to give the second projecting lens an illuminated appearance while the second lighting submodule is off.

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: 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.
