LED LIGHTENING CIRCUIT COMPATIBLE WITH MAGNETIC AND ELECTRONIC FLOURESCENT LAMP BALLAST

As an LED lamp driving circuit compatible with both a magnetic ballast and an electronic ballast, an LED lamp driving circuit is operated in a state without a configuration of the proposed circuit since being operated by high impedance with respect to the magnetic ballast, and is effectively operated with respect to the electronic ballast, in which a high-efficiency compatible type LED lamp has a circuit configured to enable the electronic ballast to recognize even an LED lamp using low power as a normal load. Accordingly, the present invention is mounted in a lamp apparatus regardless of type of the ballast therein. 자기식 안정기와 전자식 안정기에 모두 호환 가능한 LED 램프 구동회로로서 자기식 안정기에 대해서는 높은 임피던스로 동작하므로 제안하는 회로가 구성되지 않은 상태로 동작하며 전자식 안정기에 대해서는 유효하게 동작하되 낮은 전력을 사용하는 LED 램프에 대해서도 전자식 안정기가 이를 정상적인 부하로 인식하도록 회로를 구성된 고효율의 호환형 LED 램프.
