ELECTRODELESS DISCHARGE LAMP, STABILIZER FOR ELECTRODELESS DISCHARGE LAMP, METHOD FOR MANUFACTURING ELECTRODELESS DISCHARGE TUBE, LUMINAIRE, AND CONSTRUCTION METHOD FOR REPLACING LUMINAIRE WITH ELECTRODELESS DISCHARGE LAMP INCLUDING ELECTRODELESS DISCHARGE TUBE

摘要

PROBLEM TO BE SOLVED: To achieve both of stable light emission and easiness in replacement/installation by suppressing effects on a circuit due to heat generation, facilitating securement of compatibility and suppressing generation of noise, in an electrodeless discharge lamp.SOLUTION: A circuit supplying high-frequency power to an induction coil of an electrodeless discharge lamp includes: a step up/down circuit or a power factor improvement circuit; and a lamp drive circuit. The drive circuit is separately arranged and power transmission between the circuits is performed in direct current. A filler is filled in an airspace where the drive circuit is housed.
