본 발명은 광원구동장치에 관한 것으로, 제 1 광원부 및 제 2 광원부, 제 1 광원부 또는 제 2 광원부 중 하나의 광원부의 바이패스를 형성하는 스위칭부, 스위칭부의 동작을 제어하는 제어부, 제 1 광원부 및 제 2 광원부에 전력을 공급하는 전원부, 및 스위칭부에 소정의 전압을 전달하며, 제어부에 고장이 발생했을 때, 스위칭부를 소정의 상태가 되도록 하는 레귤레이터부를 포함함으로써 로우빔 모드와 하이빔 모드를 제어하는 MCU에 고장나더라도 하이빔에 대한 바이패스를 동작시켜 하이빔을 오프할 수 있다.

    The present invention relates to a light source driving apparatus. The light source driving apparatus includes: a first light source part and a second light source part; a switching part forming a bypass of one of the first light source part or the second light source part; a control part controlling the operation of the switching part; a power supply part supplying power to the first light source part and the second light source part; and a regulator part transmitting a predetermined voltage to the switching part and bringing the switching part to a predetermined state when failure occurs in the control part. Therefore, it is possible to activate a bypass for a high beam and turn off the high beam, even if an MCU for controlling a low beam mode and a high beam mode fails.
