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.

Claim (Index 12):
The dimming device of a SCR switch according to  claim 8 , wherein a voltage between a gate and a source of the N-channel MOS transistor is controlled to decrease but still be larger than or equal to a turning-on threshold value of the N-channel MOS transistor for turning on the N-channel MOS transistor, when the phase angle of the SCR switch increases but is still smaller than or equal to a threshold value to decrease the stable direct current signal; such that an on-resistance of the N-channel MOS transistor increases and an output current of the N-channel MOS transistor decreases which decreasing an output current and a forward conductive voltage of the plurality of serially connected LED lamp groups, and meanwhile a voltage difference between an input terminal of a first LED lamp group and an output terminal of a last LED lamp group is equal to or larger than a sum of forward conductive voltages of all the LED lamp groups, then the plurality of serially connected LED lamp groups are turned all on with a decreasing brightness;\n wherein the voltage between the gate and the source of the N-channel MOS transistor to is controlled to decrease to be smaller than the turning-on threshold value of the N-channel MOS transistor for turning off the N-channel MOS transistor, when the phase angle of the SCR switch increases to be larger than the threshold value; such that the plurality of serially connected LED lamp groups are turned all off.
