ABSTRACT:
When the starting of the discharge lamp has been detected at least once, the control circuit increases the number of repetitions of a period while the high frequency voltage and the square wave voltage are being outputted alternately. In such a way, in the discharge lamp lighting device that alternately generates the high frequency voltage and the square wave voltage at the time of starting, sure startability is ensured.
