A lighting module of a motor vehicle signaling device includes a ceramic substrate having opposite first and second faces, and a plurality of selectively activatable light sources mounted on the first face of the ceramic substrate. Each of the first and second faces of the ceramic substrate are provided with at least a first and a second respective interconnection layer. The ceramic substrate comprises a plurality of through holes designed to interconnect the first interconnection layer to the second interconnection layer.

Motor vehicle lighting module comprising a ceramic substrate

A lighting module for a motor vehicle signaling device includes a substrate provided with an electronic circuit on which a matrix arrangement of elementary light sources is mounted, and wall through which light emitted from the light sources can pass. The substrate and/or all or part of the elementary light sources are bonded to the wall.

Lighting module for a motor vehicle

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.

Light module for a motor vehicle

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.

Matrix light source for a motor vehicle

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.

Matrix lighting device with time of flight estimation

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.

Voltage-controlled matrix light source with diagnostic circuit for a motor vehicle

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.

Light device for a motor vehicle, comprising a matrix light source

A light source intended to be supplied with power by a voltage source. The light source includes a parallel assembly of at least two branches, each branch including at least one elementary light source having an electroluminescent semiconductor element, and each of the elementary light sources has a high internal series resistance.
