The present invention relates to a head lamp apparatus for a vehicle, controlling a power supply to a laser diode using a light quantity of white light output from a headlamp device using the laser diode as a light source to the outside, and more specifically, controlling the power supply by using only the light quantity of the pure white light where the light quantity of noise light is removed when the power supply to the laser diode is controlled in order to maximally prevent external exposure of a blue laser beam harmful to a human body and accurately control the headlamp.

    본 발명은 차량용 헤드램프 장치에 관한 것으로, 레이저 다이오드를 광원으로 사용하는 헤드램프 장치에서 외부로 출력되는 백색광의 광량을 이용해서 레이저 다이오드로의 전원공급을 제어하고, 특히 레이저 다이오드로의 전원공급을 제어할 때에 노이즈광의 광량이 제거된 순수한 백색광의 광량만을 이용해서 전원공급을 제어할 수 있도록 함으로써, 인체에 유해한 블루 레이저 빔의 외부 노출을 최대한 방지할 수 있을 뿐만 아니라 정확한 헤드램프의 동작제어가 가능하도록 된 것이다.
