PROBLEM TO BE SOLVED : To provide an electrodeless fluorescent lamp capable of raising lamp efficiency and restraining deterioration of a luminous flux of the lamp, and to provide a lighting fixture using the electrodeless fluorescent lamp.SOLUTION : The electrodeless fluorescent lamp includes a bulb 1 formed of a translucent material with discharge gas and mercury enclosed, an induction coil 15 for generating a high-frequency electromagnetic field under current conduction of high-frequency current, and a phosphor film 4 arranged at an inner wall surface side of the bulb 1 and converting ultraviolet rays generated by electric discharge of the discharge gas based on actions of the high-frequency electromagnetic field into visible light. The discharge gas is a mixed gas of a rare gas and oxygen gas, and a volume ratio of the oxygen gas to that of the mixed gas is to be 0.1-30%.COPYRIGHT : (C)2012, JPO&INPIT |
