摘要：
A process and a device for controlling a plurality of LED assemblies of an automotive vehicle, each LED assembly (Gi) executing a specific lighting/signalling function. The electrical power level (Pi) delivered by the electrical source is modulated according to distinct power levels (Pi) with relation to the function associated with each LED assembly (Gi) and temporary multiplexing is executed in order to successively transmit the distinct power levels (Pi) to the assemblies (Gi) over a multiplexing period (Tmux). Demultiplexing is effected and each distinct electrical power level (Pi) is selectively delivered to the LED assembly (Gi) concerned.
