Abstract

본 발명은, LED 조명장치에 있어서, 교류전압을 정류하여 직류의 정류전압으로 변환하는 정류회로와; 상기 정류회로로부터 전류를 공급받는 부하로서 1개 이상의 LED를 갖는 LED 발광블럭과; 상기 LED 발광블럭에 공급되는 전류를 조절하는 전류원; 및 상기 교류전압을 기초로 산정된 정현파 설계전류 값을 산출하고, 상기 산출된 설계전류 값을 상기 전류원으로 제공하여, 상기 LED 발광블럭에 공급되는 전류가 상기 설계전류 값보다 큰 경우에는 상기 전류원에 걸리는 전압강하가 조절되도록 하여 상기 설계전류 값만 상기 LED 발광블럭에 공급되도록 제어하는 제어기;를 포함하여, 교류전압이 변하면 상기 설계전류를 변경하여 LED 조명장치의 밝기를 일정하게 하는 것을 특징으로 하는 교류구동 LED 조명장치에 관한 것이다.
