Abstract
The most of metalhalide lamp is what the momentary restarting cannot be realized when the arc tube is in the hot condition. But if the lamp is restarted in the hot conditidn, we must supply the high voltage pulse with 15kv between the both electrodes of lamp. The proposed ignitor has two ignitors. If we connect each ignitor at the both sides, the high voltages of two different frequencies are generated. if so, when the one of the ignitor generates the highest voltage and the other applied generates the lowest voltage. At this time, the widest difference of voltage is applied to electrodes of the lamp. In this way, we can restart the lamp with the voltage 15kv, even if the lamp is in the hot condition.
