What is PWM dim?
Pulse width modulation (PWM) is a method through adjust to make the LED dimming power supply current to square wave, the pulse width is variable, and the modulation of the pulse width is converted into a time for modulating the continuous illumination of the LED lamp, at the same time, the input power is changed, thereby achieving energy saving and well dimming.
