Device for driving a plurality of light blocks of a motor vehicle

摘要

A driver device (P) for a plurality of light blocks (LED_DRL/PL, LED_TI) of a motor vehicle comprising at least two inputs (P1, P2), each of the inputs being suitable for receiving, respectively, a first and a second execution control signals (SCF_DRL, SCF_TI/PL), the driver device being suitable for selecting at least one of the light blocks as a function of at least one of the execution control signals and delivering an electrical power supply to said selected light block, the driver device comprises at least one controller receiving said execution control signals, the controller being suitable for delivering, as a function of the logic state of execution control signals, a switching control signal (SCC) for switching the electrical power supply to the selected light block or blocks and a control signal for controlling the level of power (SCA) of the electrical power supply of the selected light block or blocks.
