Abstract

본 발명은 LED 조명용 통합 전원 집적 회로를 공개한다. 본 발명은 교류전원이 입력되면 정류기가 교류 전원을 정류하여 평활화 되지 않은 직류 전원을 출력하고, 평활화 되지 않은 직류 또는 평활된 전원을 DC/DC 컨버터를 통해서 PWM 제어를 수행하여 전체 LED 그룹의 Vf 값에 적합하도록 강압한 후, 각 LED Vf 값에 해당하는 전압 위상에 동기하여, DC/DC 컨버터에서 출력되는 전압에 대응되는 Vf 값을 갖는 LED 그룹을 선택하여 점등시킴으로써, 종래 기술에서 이용되던 전해콘덴서 및 트랜스포머를 사용하지 않고도 조명용 LED를 구동할 수 있게 되었고, 이에 따라서 LED 조명용 전원 집적 회로의 수명을 현저하게 향상시키는 효과가 있다. 또한, 본 발명은 조명 기기의 온도를 측정하여, 측정 온도가 사전에 설정된 온도 이상으로 상승하면 LED 그룹으로 흐르는 전류를 자동으로 차단시킴으로써, 과도한 온도 상승으로 인해서 LED 조명용 통합 전원 집적 회로 전체가 열화되는 것을 방지할 수 있다.
