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: 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.

Abstract: A Fresnel lens with Fresnel prisms having a first facet, called the main facet, and a second facet, called the draft facet, the draft facet making a draft angle to the optical axis, the draft angle being variable along at least one Fresnel prism, so that the draft angle is higher on one side of the lens than on the other.

Abstract: A luminous device for a motor vehicle, said device including a pixelized light source and an optical system that is arranged to project a pixelized light beam emitted by the pixelized light source, the optical system comprising a first mirror arranged to collect and reflect rays of the pixelized light beam emitted by the pixelized light source, a second mirror arranged to reflect the rays reflected by the first mirror, and a third mirror arranged to receive the rays reflected by the second mirror and to reflect these received rays so as to correct field aberrations. The invention enables improved projection of a pixelized light beam by a luminous motor-vehicle device.

Abstract: An optical wireless communication system for a vehicle comprises a photonic device and control electronics configured to control the photonic device. The photonic device comprises a plurality of photonic components arranged in a two-dimensional matrix array, and the control electronics are configured to control individually or in groups the photonic components of the plurality of photonic components.
