| 摘要 |
An arc discharge lamp system comprises a third electrode for igniting the arc discharge lamp in addition to first and second electrodes which provide a main discharge current path for sustaining arc discharge after the lamp has been ignited by a high-voltage, high-frequency signal applied to the third electrode. In an embodiment, an igniter circuit is connected to provide the high-voltage, high-frequency signal to the third electrode of the lamp by using a low-voltage DC power supply.
