Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.
제1도는 본 발명의 기본 구성이 되는 RLC공진 회로도, 제2도는 제1도의 동작에 따른 Q와 F의 관계도(a)는 시동1단계로써 C0,L0,C1직렬 공진시의 Q-F관계도, (b)는 시동 2단계로써 점등 주파수를 down시켰을 경우의 C0,C0,C1공진시의 Q-F관계도, (c)는 3단계로써 램프가 아크방전 영역이 되고 C0,L0 공진시의 Q-F관계도, 제3도는 본 발명의 일 실시예를 하프 브릿지로 수성한 경우의 회로도.1 is an RLC resonant circuit diagram of the basic configuration of the present invention, FIG. 2 is a relationship diagram of Q and F according to the operation of FIG. 1 (a) is a QF relationship diagram of C0, L0, and C1 series resonances as a first stage of startup. (b) shows QF relationship when C0, C0, C1 resonates when the lighting frequency is turned down in two stages of start-up, and (c) shows QF relationship when the lamp becomes arc discharge region and C0, L0 resonates in three stages. 3 is a circuit diagram when an embodiment of the present invention is formed by half bridge.
