What is the principle of led dimmer ?
LED dimmers use electrical circuits to control the brightness of LED lights.
The most commonly used method is to use the PWM, PulseWidthModulation, signal to adjust the driving current of the LED.
In PWM, the current goes through a series of on and off cycles, and the percentage of the "on" time to the total time is called the duty cycle.
Adjusting the duty cycle can change the brightness of the LED.
There is also voltage dimming and current dimming methods.
