Triac DimmAble Led Driver in stock
|Analysis of traditional incandescent, halogen and other dimming systems, because compared with LED lights, incandescent and halogen lamps are purely resistive devices, which means that its current waveform and voltage waveform will always be the same, when available When the silicon is used to adjust the light, the input voltage waveform deviates from the sine wave due to the change in the conduction angle of the thyristor, that is, the effective value of the input voltage is changed, and the purpose of dimming can be achieved.
