An embodiment of the present invention relates to a light driving apparatus which comprises: a light source unit; a first sensing unit sensing the value of an input current of the light source unit; a second sensing unit sensing the value of an output voltage of the light source unit; and a control unit sensing the value of the output voltage through the second sensing unit, based on the value of the input current sensed by the first sensing unit and determining a state of the light source unit, based on the value of the output voltage, wherein the control unit starts an operation of sensing the value of the output voltage through the second sensing unit after the first debouncing time passed from a start timepoint when a current starts being applied to the light source unit and stops the operation of sensing the value of the output voltage through the second sensing unit before a second debouncing time rather than an end timepoint when the current being applied to the light source unit is blocked. Accordingly, an error caused by mistakenly sensing the voltage of the light source unit at the start timepoint when the current starts being applied or the end timepoint when the current is blocked can be solved.

    실시 예에 따른 조명 구동 장치는 광원부; 상기 광원부의 입력 전류 값을 감지하는 제1 감지부; 상기 광원부의 출력 전압 값을 감지하는 제2 감지부; 및 상기 제1 감지부를 통해 감지된 입력 전류 값에 기초하여 상기 제2 감지부를 통한 상기 출력 전압 값을 감지하고, 상기 출력 전압 값에 기초하여 상기 광원부의 상태를 판단하는 제어부를 포함하고, 상기 제어부는, 상기 광원부에 전류가 인가되기 시작하는 시작 시점으로부터 제1 디바운싱 시간이 경과한 이후에 상기 제2 감지부를 통한 상기 출력 전압 값의 감지 동작을 시작하고, 상기 광원부에 인가되는 전류가 차단되는 종료 시점보다 제2 디바운싱 시간 이전에 상기 제2 감지부를 통한 상기 출력 전압 값의 감지 동작을 중지한다.
