Abstract: A lighting module for an automotive vehicle includes a plurality of lighting sub-modules each including at least one light source, a flat optical light guide with an input surface, and an output surface and a reflection surface which is capable of reflecting light from the input surface to the output surface. The plurality of lighting sub-modules includes first lighting sub-modules configured to each produce a lighting sub-beam with an upper horizontal cut-off, and second lighting sub-modules configured to each produce a lighting sub-beam without an upper horizontal cut-off. The first and second lighting sub-modules are juxtaposed so as to form, along the juxtaposition, a plurality of alternations between the first and second lighting sub-modules.

Abstract: A process for mounting a light component on a carrier. The light component includes a generally planar substrate, on a first face of which submillimetre-sized electroluminescent semiconductor elements are epitaxied in the form of a matrix. The process is noteworthy in that it eliminates the need for a layer of filler material between the component and the carrier, while providing good thermal and electrical conductivity between the component and the carrier and high mechanical strength.

Abstract: An object detection system for a motor vehicle is proposed. The system includes an array of electroluminescent light sources, an array of light sensors and a calculating unit. At least one of the electroluminescent light sources is able to emit a signal. At least one of the sensors is able to receive the emitted signal that has been reflected by an object. The calculating unit is able to calculate, by triangulation, the position of the object on the basis of the position, in one of the arrays of electroluminescent light sources, of at least one of the electroluminescent light sources able to emit a signal and on the basis of the position, in one of the arrays of light sensors, of at least one of the sensors able to receive the signal reflected by the object.
