Gas discharge lamp lighting device |
摘要 |
A gas discharge lamp lighting device includes a DC/DC converter for adjusting electric power supplied from a power supply to generate and output a DC voltage, and an FET electrically connected to the DC/DC converter, for converting the DC voltage from the DC/DC converter to an AC voltage to be supplied to a gas discharge lamp. A control unit brings the gas discharge lamp to an electrode heating state in which both electrodes of the gas discharge lamp are heated after supplying the AC voltage to the gas discharge lamp. The control unit controls energy supplied to the gas discharge lamp in the electrode heating state according to a voltage across the gas discharge lamp. The control unit brings the gas discharge lamp to an AC discharging state in which an AC current flows through the gas discharge lamp after the energy has been supplied to the gas discharge lamp.
