Title: 고압 나트륨 램프 동작을 위한 방법 및 회로
IPC: H05B41/288
Filed: 2001-07-09
Abstract: 고압 나트륨 램프는 회로를 이용하여 동작될 수 있는데, 그 회로는 교류 공급 전압을 정류하고, 평활화 단계를 제거하는 반면, 1kHz보다 더 큰 주파수를 발생시키기 위해 공급 전압을 전력 인버터에 직접적으로 공급한다.  전력선 주파수의 2배가 되도록 변조된 상기 전압은 HF 유도성 저항과 점화 송신기를 경유하여 램프에 공급되고, 상기 램프는 바람직하게 1 bar를 초과하는 압력까지 크세논(xenon)으로 채워져 있다.  상기 시스템 램프 안정기에 대한 전기 에너지 절전률은 동일 광속을 갖는 초크오퍼레이티드(choke-operated) 무수은 표준 램프와 비교하여 30 %에 이른다.  해프 브리지(half bridge)를 제어하기 위해 마이크로프로세서를 사용하는 것은 외부적으로 제어되는 전력 감소 또는 자동적인 전력 감소를 가능하게 하며 사이클링을 막기 위해 시스템의 엔드 오브 라이프 차단을 가능하게 한다.
