Abstract: The subject of the invention is a reflector device for a lighting module of a motor vehicle. The device includes a housing made of plastic, wherein the internal faces are metallized so as to reflect the light received. The housing on an external face of one of its walls has reception means able to house a support including at least one light source, the wall having an opening which leads toward the inside of the housing and which allows the light emitted by the light source or sources to propagate toward the inside of the housing. According to the provisions of the invention, the external face of the housing may be connected to ground potential so as to act as a shield against the electromagnetic waves emitted by various electronic components.

Abstract: The invention proposes a luminous device involving a converter intended to supply power to a pixelated light source controlled by electric current. The device makes it possible to reduce power losses and to reduce the risk of the elementary light sources of the pixelated light source overheating. By using a control loop and measuring means which make it possible to directly or indirectly measure a value which is indicative of the voltage drop at the terminals of at least one current source of the pixelated light source, it becomes possible to dynamically adapt the voltage delivered by the converter circuit.

Abstract: A lighting system for a motor vehicle with a pixelated light source having a plurality of selectively activatable elementary light sources is described. The activation of each elementary light source being controlled exclusively by a switch assigned to the elementary light source. A power converter designed to supply an electrical power to the pixelated light source and a controller designed to control the voltage supplied by the power converter and to control the switches controlling the activation of the elementary light sources. The lighting system also includes an electrical current sensor designed to measure the electrical current supplied by the power converter to the pixelated light source and to transmit information relating to said measured current to the controller.

Abstract: A light module for a motor vehicle, including a first electrical assembly on a first carrier, which harbours a plurality of branches that are connected in parallel, each branch including light sources, preferably light-emitting diodes. The module includes a second carrier which includes a control unit for controlling the supply of electrical power to the light sources, the control unit including a feedback loop from a reference branch. The light module allows the number of connections between the two carriers of the assembly to be decreased and reliability thereof to be increased.

Abstract: A motor vehicle lighting system includes a light source, a multi-phase interleaved power converter having a plurality of selectively activatable elementary converters, each of which is configured to generate an electrical signal having its own phase. The power converter is designed to supply electrical power to the light source, and controller is designed to selectively control each of the elementary converters of the power converter. The controller is designed to receive an emission command for the emission of a desired light beam by the light source and to activate a strictly necessary number of elementary converters of the power converter such that the power converter supplies, to the light source, an electrical power needed to emit the desired light beam.

Abstract: The invention relates to a converter of SEPIC type intended to convert a first DC voltage into a different second DC voltage. The converter is noteworthy in that it allows a slaving in terms of output current by way of an indirect measurement which is sensitive neither to the coefficient of coupling between the inductors L1 and L2, nor to the ratio L1/L2.
Abstract translation: 本发明涉及一种用于将第一直流电压转换为不同的第二直流电压的SEPIC型转换器。 该转换器值得注意的是，它允许通过间接测量而在输出电流方面无效，也不影响电感器L1和L2之间的耦合系数，也不敏感L1 / L2比。
