を目的とした高周波電流制御方式。[Scope of claim for utility model registration] The voltage of a detection circuit that is connected in series with a metal halide lamp and causes a voltage drop in proportion to the current flowing,
By using it as a bias voltage for the variable capacitance diode, the capacitance of this variable capacitance diode connected to the oscillator is changed according to fluctuations in the current flowing through the metal halide lamp, thereby controlling the oscillation frequency. By controlling the output frequency of the inverter circuit driven by the oscillation frequency of this oscillator, the reactance of the transformer inserted in series with the metal halide lamp is changed to automatically control the high frequency current supplied to the metal halide lamp. A high-frequency current control method aimed at eliminating flickering in the luminous flux of metal halide lamps.
