Abstract
A silicon controllable dimming full-range flickfree circuit includes a dimming circuit and a flick elimination circuit which includes a metal oxide semiconductor (MOS) connected with an output terminal of the dimming circuit. The dimming circuit and the flick elimination circuit are combined, and the dimming circuit is provided with a silicon controllable dimming chip. Thus, when the MOS is worked at the constant current zone, the voltage of the source and the gate of the MOS is kept at a constant value, so that the current passing through the source and the drain of the MOS is kept at a constant value, to perform a flickfree feature of the full-power range of the high power factor, to stabilize the operation of the LED circuit, and to prevent the user's eyes from being hurt by the flick of the LED circuit.
