Estimating the term…
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.
A control process for a plurality of LED assemblies of an automotive vehicle from an electrical power source, there being associated with each LED assembly a specific lighting and/or signalling function, wherein for a given rated electrical power of the source, this process comprises at least the following steps:
A control device for controlling a plurality of LED assemblies of an automotive vehicle from an electrical power source, there being associated with each LED assembly at least one lighting or signalling function, wherein, for a given rated electrical power of the source, this device comprises at least:
