High voltage discharge lamp device |
摘要 |
<p>In a discharge lamp control circuit (100) for a discharge lamp (2), a capacitor (53) in a starting circuit (8) is charged by a high voltage generated by a transformer (29) used in a direct current power source circuit (5). A transformer (47) necessary for the starting circuit (8) and the transformer (29) necessary for the direct current power source circuit (5) can commonly be used for cost reduction. Further, a thyristor (57) is used in the starting circuit (8) in place of a gap for activating the discharge lamp (2). <IMAGE></p> |
