Abstract: A system for supplying electrical power to at least one semiconductor-element-including light source of a motor vehicle. The system includes a mechanism controlling the supply of electrical power to the light source and being configured to deliver an electrical current to the light source. Magnitude of the delivered electrical current depends on a bin value of the light source and on the temperature of the environment of the source. An electronic circuit, which is independent of the light source, including a first component a measurable property of which is representative of the bin value of the source, and a second component a measurable property of which is dependent on the temperature of the environment of the light source. The controller determines the properties of the first and second components via a single electrically conductive wire connecting the controller to the electronic circuit, the wire being suitable for supplying the latter with electrical current.

Abstract: The invention proposes a matrix light source having a plurality of elementary light sources with light-emitting semiconductor elements, and a common substrate in contact with an integrated circuit. The integrated circuit allows a brightness setpoint to be stored for each elementary light source of the matrix source, and comprises a circuit for managing the power supply for each source, allowing the brightness setpoint to be implemented without needing other external controls.

Abstract: The invention proposes a lighting device for a motor vehicle comprising a matrix light source that performs a lighting function within the motor vehicle. The same source is used, together with a photodiode, to estimate the time of flight of captured light pulses initially generated by the matrix source. It becomes possible to detect objects and/or gestures using light in the visible spectrum, and without having to use specific pulse sources dedicated for this purpose.

Abstract: A motor vehicle signaling device light module includes a substrate on which a matrix arrangement of elementary light sources is mounted, a connector fixed to the substrate having a rectangular footprint with a long side and a narrow side, and a support designed to hold the substrate in position in the signaling device. The substrate is curved around an axis of curvature, and the light sources are arranged to produce a convex display from the point of view of a user outside of the vehicle, so that the long side of the connector is substantially parallel to the axis of curvature.

Abstract: The invention relates to a light device for a motor vehicle, comprising a matrix light source having a matrix of elementary light sources with an electroluminescent semiconductor element. Each elementary light source has an emitting surface that is less than or equal to 0.2 mm2. The measures proposed by the invention allow such a matrix light source to be powered without any risk of damage due to overheating of the semiconductive junctions of the elementary light sources that make up the light source.
