[0002] Thyristor dimming is a traditional AC circuit dimming method, which is widely used in lighting control, especially for incandescent lamps and some early LED lamps. The core of thyristor dimming lies in adjusting the effective value of the output voltage by changing the conduction angle (i.e., the time ratio from the start of conduction to the cut-off of the thyristor within an AC cycle), so as to control the brightness of the load (such as a light bulb). Specifically, the circuit usually includes a thyristor, a trigger circuit, a phase-shifting network, and a load. The thyristor serves as the main control element, and the thyristor controls the passage of current according to the timing of the trigger signal; the trigger circuit is used to provide a trigger pulse to the thyristor at an appropriate time point in each half cycle, usually including a potentiometer, a capacitor, a resistor, and a comparator or directly using a dedicated trigger circuit chip; the phase-shifting network consists of a potentiometer and a capacitor, which is used to adjust the phase difference of the trigger pulse relative to the zero-crossing point of the AC power supply voltage, thereby changing the conduction angle; the load is the light bulb or other load to be dimmed; existing intelligent lights cannot be connected to thyristor dimmers, and the original thyristor dimmers need to be removed again during project renovation, and the functionality needs to be improved.
