摘要： A discharge lamp lighting system including at least one switch device connected between a d.c. power supply and a discharge lamp which is turned on by a high frequency power generated through turning-on and -off of the switching device. In the discharge lighting system, the discharge lamp lighting operation is allowed to start when the d.c. power supply voltage reaches a predetermined voltage value A or over, and the discharge lamp lighting operation is stopped when the d.c. power supply voltage lowers smaller than a predetermined voltage value B, where the values A and B take a relation that B is smaller than A.
