For TRIAC dimming LED strip, the biggest problem presently is the compatibility of the dimmer. Traditional original design of the TRIAC dimmer was to handle the power consumed by hundreds of watts of incandescent bulbs. Power consumption of LED strip smaller than 20W will interact with dimmers made of high-power switching devices. If the interaction between the triac dimmer and the ...
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. The frequen...
