ELECTRODELESS DISCHARGE LAMP DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electrodeless discharge lamp device for ready change of the design of a high frequency power circuit for an electrodeless discharge lamp, and attaining control by reduction in the manufacturing cost of the device and increase in the efficiency in electric power. SOLUTION: This electrodeless discharge lamp device is provided with the electrodeless discharge lamp 18, an excitation coil 17 arranged in the vicinity of the periphery of the electrodeless discharge lamp, a resonance circuit 16 for supplying proper electric power to the exciting coil, a high-frequency power source 10 for supplying resultant output of parallelly arranged power sources arranged plurally in parallel with the resonance circuit and a driving circuit 12 of the high-frequency power source, and is constituted so as to obtain the resultant output by synchronously or causing almost synchronous driving of the plural power sources arranged in parallel.
