Title (EN) LED LIGHTING APPARATUS INCLUDING HIGH POWER LED DRIVING CIRCUIT
(FR) APPAREIL D’ÉCLAIRAGE À DEL COMPRENANT UN CIRCUIT D’ENTRAÎNEMENT DE DEL HAUTE PUISSANCE
(KO) 고출력 LED 구동회로를 구비한 LED 조명장치
Abstract:
(EN) The present invention relates to an LED lighting apparatus comprising a high power LED driving circuit, and more particularly to a high power LED lighting apparatus which comprises a power factor compensating unit capable of supplying a stabilized driving voltage to LED drive ICs that control a plurality of light emitting groups, each comprising a plurality of LEDs, such that the plurality of light emitting groups are sequentially driven according to the voltage level of the driving voltage.
(FR) La présente invention concerne un appareil d'éclairage à DEL comprenant un circuit d'entraînement de DEL haute puissance, et plus particulièrement un appareil d'éclairage à DEL haute puissance qui comprend une unité de compensation de facteur de puissance permettant de fournir une tension d'entraînement stabilisée aux circuits intégrés (IC) d'entraînement de DEL qui régulent une pluralité de groupes électroluminescents, chacun comprenant une pluralité de DEL, de sorte que la pluralité de groupes électroluminescents sont entraînés séquentiellement en fonction du niveau de tension de la tension d'entraînement.
(KO) 본 발명은 고출력 LED 구동회로를 구비한 LED 조명장치에 관한 것으로, 각기 복수의 LED들을 포함하여 구성된 복수의 발광그룹들 및 복수의 발광그룹이 구동전압의 전압레벨에 따라 순차구동되도록 제어하는 LED 드라이브 IC에 안정화된 구동전압을 공급할 수 있는 역률 보상부를 구비한 고출력 LED 조명장치에 관한 것이다.
