ELECTRICAL DISTRIBUTED ARCHITECTURE FOR LIGHTING IN A MOTOR VEHICLE

The invention proposes the use of a unique Boost-type converter (114) to supply a plurality of lighting modules (120, 130) of a motor vehicle with electrical voltage. Each module comprises a dedicated Buck-type converter (124, 134) in order to ensure the regulation of electrical current so as to satisfy the requirements of the light sources (122, 132) of the lighting module in question. A communication network (102) connecting the centralized element (110) 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 components of the motor vehicle.
