조광 제어방식Dimming Control Method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명의 조광 제어방식에 대한 블록도, 제3도는 모드선택용 스위칭부(11)의 일실시 예시도.2 is a block diagram of a dimming control method of the present invention, and FIG. 3 is an exemplary view of a mode selection switching unit 11.

Claims (1)

모드설정용 스위칭부(15)상에서 설정되는 모드에 따라 중앙처리장치(15)가 조광 레벨설정용 디지탈신호(DS), 아날로그 신호(AS), 자체설정값중에서 하나를 받아들여 메모리(16)의 타임테이블에서 해당도통각에 대응되는 타임데이타를 읽어와 타이머를 설정하고, 다음 제로 크로싱 지점으로 부터 타이머가 온되는 시점에서 점호용 펄스를 출력하여 조광부하(30)에 해당전력이 공급되도록 하는 것을 특징으로 하는 조광 제어방식.According to the mode set on the mode setting switch 15, the central processing unit 15 receives one of a dimming level setting digital signal DS, an analog signal AS and its own setting value, Read the time data corresponding to the corresponding conduction time from the timetable, set the timer, and output the firing pulse at the time when the timer is turned on from the next zero crossing point so that the corresponding power is supplied to the dimming load 30. Dimming control system characterized by. ※ 참고사항 : 최초출원내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
