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: The invention relates to a device for the electrical connection of at least one light source to an electric power supply device. The device is specifically employed in a lighting device for a motor vehicle, and permits the arrangement of light sources remotely from the connecting element which, in turn, can be arranged remotely from an electric power supply device of the light sources. The connecting device permits a high degree of freedom in the arrangement of light sources in relation to the device, as it casts little shadow upon the light sources, whilst ensuring the effective dissipation of heat generated thereby.
