Abstract: A lighting device for a motor vehicle includes a housing having a front lighting surface, and a substantially planar plate and at least one lighting module mounted on the plate. The plate has a general plane of extension that is horizontal when the housing is mounted in the vehicle, and has a surface referred to as a lower surface and a surface referred to as an upper surface. The plate includes a first control system which includes a first male element and is arranged to cause translation of the first male element in an axis parallel to the plate, the plate being provided with a first recess receiving the first male element. A second control system that includes a second male element and is arranged to cause translation of the second male element in an axis perpendicular to the plate, the plate being provided with a second recess on its upper or lower surface that receives the second male element. The housing thus takes up less space above the modules, which can easily be raised.

Abstract: A heat sink for an electronic component and its manufacturing method by applying a nanopulsed laser. The heat sink includes a body provided with an outer layer, including a surface layer having a radiative exposed surface and a layer immediately underlying the surface layer. The underlying layer is made of a material based on a metal and the surface layer is made of an oxide of said material. The outer layer includes juxtaposed nodules. The heat sink originally combines a surface chemical state promoting heat emission and a structure geometrically promoting heat exchange, in order to synergistically improve its heat dissipation capability.

Abstract: Method for controlling modules for projecting pixelated light beams of a host vehicle. The host vehicle includes a step of determining, using a control device and according to the collected data, a polynomial function which models the profile of the edge and the centre of the road, such that the road profile is modelled based on a polynomial function, the degree of which depends on the curvature of the road. Also included is a step of determining, by means of the control device, a starting point (Pd) and an arrival point (Pa) of an area for projection (ZPd, ZPg, ZP) of patterns, and a step of determining, by means of the control device, a distance (De) between an axis (Ac) of a data/image acquisition means and the patterns, respectively for a right projection area ZPd and a left projection area ZPg. The control device is used to determine the width (Lm) of the pattern.

Abstract: A method for controlling a lighting system for a motor vehicle having a system for detecting objects includes defining at least one set of detectable types of objects and acquiring, by means of the detection system, a set of data relating to the position of a plurality of objects of types belonging to the set. Also included is determining a lighting model which is associated with said set and defines at least one zone referred to as the initial detection zone, and a light pattern referred to as the initial light pattern, of a light beam intended to be emitted in the initial detection zone. The lighting system is controlled in order to emit a light beam having the initial light pattern in the initial detection zone of said lighting model.
