Title: Discharge lamp lighting device
Inventor: KAKIYA TSUTOMU
IPC: H05B41/24
Filed: 1996-10-19
Abstract: PROBLEM TO BE SOLVED: To enable a discharge lamp to be turned ON/OFF and the light to be adjusted by a simple operation (or common control signal) and prevent a dark state from being entered by turning ON the discharge lamp in case of emergency in which a light adjustment signal is not sent. SOLUTION: An inverter 1 changes output by controlling a switching frequency. A discharge lamp 7 is energized by the output of the inverter 1 and is light-adjusted and turned ON according to the change of the output of the inverter 1. A signal transmission means 10 transmits a PWM signal, and a drive unit changes the frequency of the switching signal in the relationship in which the output of the inverter 1 increases as an on-duty decreases according to the on-duty of the PWM signal. An output stop unit 9 lowers the output of the inverter 1 so that the discharge lamp 7 goes out when the PWM signal is a consecutive signal.
