Abstract

본 발명은 엘이디 구동 제어 장치 및 이의 구동 전류 제어 방법에 관한 것이다. 보다 상세하게는 교류 전원을 이용하여 직류 구동 엘이디 모듈 또는 교류 구동 엘이디 모듈을 구동시키는 것이 가능한 엘이디 구동 제어 장치 및 이의 구동 전류 제어 방법에 관한 것이다. 본 발명에 의하면 입력 전압이 변동되더라도 정전류 또는 정전력 제어에 의해 엘이디 어레이의 구동 전류를 정현파 형태로 출력할 수 있으므로 고조파 억제, 역률 개선, 플리커 현상 최소화, 및 엘이디 어레이 및 엘이디 구동 제어 회로의 온도 상승을 방지할 수 있는 효과를 갖는다.
