CONSTITUTION: A lighting circuit formed of a DC power source 103, a full-bridge inverter circuit 14, and a starting circuit 15 has such a constitution that transistors 117, 120 and transistors 118, 119 are alternately ON/OFF according to the output signal of a driving circuit 220 to invert the output of a step-down chopper circuit 116 into alternating current, and a rectangular wave lamp current of 4kHz is supplied to a metal halide lamp 210. Thus, the peak value of arc temperature near an electrode which changes timewise is minimized, and the sputtering by positive ion of a cathode is also suppressed. Consequently, the evaporation and scattering of the electrode can be suppressed to suppress the blackening of the lamp.
