ABSTRACT:
A lighting circuit reduces the chance of shifting the generation timing for a start pulse with respect to the polarity of a rectangular wave. The lighting circuit has a start pulse generator which is designed to generate a start pulse only when the rectangular wave voltage obtained by a DC-AC converter has a certain polarity. A lighting discriminating circuit discriminates the ON status or OFF status of a discharge lamp. A lighting frequency controller is provided to alter the lighting frequency so that the frequency of the rectangular wave output from the DC-AC converter when the OFF status of the discharge lamp is discriminated becomes lower than the frequency of the rectangular wave output from the DC-AC converter when the ON status of the discharge lamp is discriminated.
