Abstract

누 전류를 차단할 수 있도록 함과 더불어 엘이디의 구동을 원활하게 할 수 있도록 한 엘이디 구동장치를 제시한다. 제시된 엘이디 구동장치는 메탈 피씨비에 어레이된 엘이디 모듈이 복수의 상용전원 입력 라인에 연결된 장치로서, 복수의 상용전원 입력 라인에 연결되는 엘이디 모듈의 모든 입력 라인에 각각 설치되어, 엘이디 모듈의 모든 입력 라인으로의 상용전원 입력을 차단시키는 차단 소자를 포함한다. 스위치 오프시 상용전원 입력 라인 양쪽을 모두 오프시키므로, 메탈 피씨비의 회로층(동박)에 전위가 생성될 수가 없어 누설전류가 발생될 여지를 원천적으로 차단하게 된다. 즉, 스위치를 오프시키게 되면 엘이디 모듈(교류 엘이디 모듈)이 바로 오프되므로 동작 신뢰성을 얻을 수 있게 될 뿐만 아니라 불필요한 전력 손실을 방지하게 된다.
