APPAREIL DE COMMANDE D'UNE INSTALLATION D'ECLAIRAGE D'UN VEHICULE AUTOMOBILE ET SYSTEME D'ECLAIRAGE DE VEHICULE

摘要

The controller (25) has a current sensor (35) provided for detecting input current (i-e) of a main power supply of a motor vehicle. A control circuit (49) controls and/or regulates a motor vehicle lighting device. A switching element (45) has a semiconductor circuit (51) provided for separating the control circuit from the main power supply. The switching element is controlled depending on the detected input current of main power supply. The semiconductor switch is a transistor i.e. FET such as MOSFET.
