The invention notably relates to a light-emitting module of a terrestrial vehicle having at least one semiconductor light source including a mostly semiconductor material substrate, the substrate having a first face and a second face. The light source further includes electroluminescent elements with submillimeter dimensions extending from the first face of the substrate, and at least one heatsink cooperating with the second face of the substrate to evacuate the heat produced by the light source. The invention therefore offers an improved light-emitting module for terrestrial vehicles.

Terrestrial vehicle light-emitting module

A motor vehicle passenger compartment lighting system includes semiconductor light-emitting light sources and a substrate on which the light sources are grown. The light sources define a plurality of light-emitting zones (Sa, Slg, Sld), and the system is configured to activate the light source or sources of the same zone independently from one zone to another. The plurality of zones (Sa, Slg, Sld) are configured to emit beams intended to produce different lighting effects from one zone to another.

Lighting system for motor vehicle passenger compartment

An electric power supply system using a single converter of the Boost type for supplying a plurality of lighting modules of a motor vehicle with electric voltage. Each module comprises a dedicated converter of the Buck type in order to ensure the regulation of the electric current in such a way as to meet the needs of the light sources of the lighting module in question. A communication network which connects the centralized unit and the lighting modules makes it possible to ensure the control of the modules and the detection of faults, as well as to notify the latter to other devices of the motor vehicle.
