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 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.

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. Each photonic component or each group of photonic components is configured, where appropriate conjointly with an optic, so as to emit and/or receive at least one optical wireless communication signal in a propagation direction that is discriminable relatively to a propagation direction of optical wireless communication signals emitted and/or received, respectively, by at least one other photonic component or by at least one other group of photonic components of the plurality of photonic components.

A lens for shaping light rays, for a luminous lighting and/or signalling module of a motor vehicle, includes an entrance face for the light rays and an opposite exit face. The lens has a flat-lens shape the exit face of which is equipped with prisms forming a Fresnel structure, at least one of these prisms being equipped on an exterior face with diffractive structures, and the entrance face of which is at least partially equipped with microstructures. The lens applies to motor vehicles.
