摘要： A discharge lamp lighting circuit facilitates carrying out re-ignition and addresses a problem than can arise due to an influence of a capacitor in an auxiliary lighting circuit. A driving voltage generating portion supplies an AC driving voltage to a discharge lamp to be a driving target. An auxiliary lighting circuit is provided on a terminal side of the discharge lamp. An auxiliary lighting capacitor, an auxiliary lighting resistor and a switch are provided in series between the terminal of the discharge lamp and a fixed voltage terminal. A control circuit controls a conducting state of the switch. The switch is brought into an ON state before the discharge lamp is turned ON, and is brought into an OFF state after the discharge lamp is turned ON.

摘要： A discharge lamp lighting circuit is capable of preventing the discharge lamp from going out unexpectedly. The discharge lamp lighting circuit includes a DC-AC inverter which receives a power source voltage, boosts and converts the power source voltage into AC and supplies AC electric power to the discharge lamp 21. A control circuit sends a long cycle signal when the discharge lamp 21 is started. The cycle of the long cycle signal is longer than a frequency at the time of steady lighting. The control circuit sends a steady drive signal, which is a frequency at the time of steady lighting, to the DC-AC inverter 25. A cycle of the long cycle signal is set according to at least one of the power source voltage, the temperature of the discharge lamp lighting circuit or the extinguishing time.
