An inverter dimming circuit is provided to control brightness by accurately controlling a lamp through the output of a normal current waveform. An inverter dimming circuit(10) includes a PWM(Pulse Width Modulation) supplying unit(11), a controlling unit(12), and a stabilizing circuit(13). The PWM supplying unit supplies a PWM dimming signal to the controlling unit. The controlling unit receives the signal from the PWM supplying unit, and controls the operation of a lamp(14). The stabilizing circuit is formed in the path of supplying the PWM dimming signal from the PWM supplying unit to the controlling unit, and removes the noise inputted into the PWM dimming signal. The stabilizing circuit is a capacitor. |
