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.

A terrestrial vehicle lighting module which includes an electroluminescent source including at least one electroluminescent element, an electronic device designed to control the electroluminescent element, and an interposer electrically connecting the electroluminescent source and the electronic device.

Wiring of a high resolution light source

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.

A lighting module includes at least one light-emitting assembly and one lens for shaping the emitted light rays, the lens having an entrance face for the light rays and an exit face. The lens is a flat lens, the lens and the emitting assembly being configured so that the exit face includes a first section and a second section that differ in the amount of light rays exiting from the lens via one or other of these sections in order that the first section forms an optical section and in order that the second section forms a lighting neutral section. The second section extends from the first section in order to have a largest dimension that is larger than the thickness of the flat lens, the exit face of the lens including features over the entirety of its area.
