IGNITOR, HIGH VOLTAGE DISCHARGE LAMP LIGHTING DEVICE AND LUMINAIRE

摘要

PROBLEM TO BE SOLVED: To provide an ignitor electrode which stabilizes an output of high voltage pulse applied to a high voltage discharge lamp, wherein a down-sizing is also made possible. SOLUTION: By arranging a leakage flux of step-up transformer 31 nearly orthogonal to discharge triggers 32d, 32e of discharging gap 32, an early excitation of discharge gap 32 by magnetism of step-up transformer 31 is inhibited, and an output of pulse voltage can be stabilized.
