The present invention is aimed at providing an electrodeless discharge lamp lighting fixture which can secure lightness even in the case of a dimmering control at a low temperature.The electrodeless discharge lamp lighting fixtureaccording to the present invention comprises an electrodelessdischarge lamp 1, a dimmering inverter 3 which is connected to an AC power supply 11 and applies a high-frequency voltage to the electrodeless discharge lamp 1, a controlling relay 5adapted to receive an AC dimmering signal to turns ON/OFF, anda control substrate 4 which converts, into DC, the AC dimmeringsignal received from said controlling relay 5 and applies the DC dimmering signal to the dimmering inverter 3, wherein, in case the control relay 5 is ON, the control substrate 4 outputs a DC dimmering signal of 4 volts or greater, and the dimmeringinverter 3 assumes an operation mode of about 50%. |
