Abstract: The invention relates to a matrix light source comprising a plurality of elementary light sources with light-emitting semiconductor elements, and a common substrate that is in contact with an integrated circuit. The integrated circuit is configured to delay, for a predetermined duration, the light-up of the elementary sources, upon receiving a light-up command.

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.

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 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 matrix light source intended to be supplied with a voltage and having a plurality of electroluminescent semiconductor element-based elementary light sources and a common substrate in contact with an integrated circuit. The integrated circuit includes, for each elementary light source, a switching device for selectively connecting it to a voltage source on the basis of a first control signal. The substrate includes, for at least one of the elementary light sources, an open-circuit fault detection circuit for detecting an open-circuit fault with the elementary light source.
