Abstract:
A method for generating a stable direct current signal, a silicon controlled switch dimming method and device, the silicon controlled switch dimming method comprising: adjusting a phase angle of a silicon controlled switch and outputting an alternating current signal related to the phase angle of the silicon controlled switch (S 101 ); rectifying the alternating current signal (S 102 ); converting the rectified electric signal into a steady direct current signal one-to-one corresponding to the phase angle of the silicon controlled switch, and the stable direct current signal decreases as the phase angle of a silicon controlled switch increases (S 103 ); controlling turning on or off of an output current regulating circuit according to the magnitude of the stable direct current signal so as to control the plurality of serially connected LED lamp groups to be turned all on or all off (S 104 ). The generated stable DC signal one-to-one corresponds to the phase angle of the silicon controlled switch and decreases with the increase of the phase angle of the silicon controlled switch. The stable direct current signal can control work status of the plurality of LED lamp groups connected in series, thereby making the plurality of LED lamp groups connected in series be turned all on or all off.
