Title: Light source device, discharge lamp and its control method
Inventor: ITO YOSHINOBU
IPC: H05B41/19
Filed: 2008-05-02
Abstract: At an early period of a discharge start, a shield electrode is connected with the ground potential through a bidirectional voltage trigger type switch. Subsequently, electric charges in the shield electrode flow through the ground potential, and both terminals of the bidirectional voltage trigger type switch are cut off by this potential as a trigger. Thus, at the early period of the discharge, the suppression of static electrification of the shield electrode restrains the reduction of discharge. During the period to maintain the discharge, the lack of stability can be suppressed by a reluctant discharge from the shield electrode to the anode. The use of such an element automatically improves a turn-on characteristic of the discharge lamp.
