Title: Discharge lamp lighting device and lighting system
Inventor: URATANI KAZUYUKI
IPC: H05B41/24
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To economically constitute a protection function of an inverter circuit by installing a driving control circuit which controls the oscillation operation of an inverter circuit by the detection outputs of a life terminal detecting means of a discharge lamp and a lighting detecting means based on the voltage between both ends of a d.c. cut capacitor. SOLUTION: When a discharge lamp 24 reaches its life terminal, the discharge lamp is put in half-wave rectification state and a.c. component flows into a d.c. cut capacitor C11 and the d.c. component flows into resistors R11, R12. The voltage of the resistors R11, R12 generated due to that is full-wave rectified and detected by a detection capacitor C13. Since the detection output at a prescribed detection level or higher is generated, it is judged that the discharge lamp 24 reaches its life terminal and oscillation operation of an inverter circuit 22 is stopped by a driving control circuit 27. Since the life terminal detecting means 30 which detects the life terminal based on the voltage between both ends of the d.c. cut capacitor C11 of a LC resonance circuit 23 and a lighting detecting means 31 which detects the lighting failure at the time of starting are used in a common circuit, the number of parts is lessened and the lighting system is economically constituted.
