The dimming principle of triac dimmer is different from PWM dimming. The thyristor dimming power supply is a kind of physical dimming, and ordinary dimmers can be used. PWM (Pulse Width Modulation and Pulse Width Modulation) is abbreviated as Broad It is a very good technology to control the analog circuit through the dimming of the caller and the digital output. A dedicated dimmer is needed. It is widely used in many fields from measurement and communication to power control and conversion. .

Advantages of triac dimmer for led lighting:
1) High-frequency AC adjustment mode, high-intelligence equipment dimming is more accurate.

2) Small size, simple operation, no complicated program interference.

3) Thyristor dimmer has certain advantages in dimming. It can not only use direct current but also alternating current, while PWM dimmer can only use direct current. It is not convenient enough to use, but also because many current factors bring certain limitations to use. The thyristor can better control the current, can be adjusted slowly according to the demand, and can adjust the stable and soft light.

4) It has a memory function. After starting this function, the power supply can be reused the next time the lamp is turned on without adjustment.

5) The thyristor dimmer can adjust some incandescent lamps with relatively large power consumption into energy-saving lamps for the purpose to a certain extent, saving costs.
