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.

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.
