What is a leading edge dimmer? What is a trailing edge dimmer?

- Dec 29, 2018-


A: The working mode of the leading edge dimmer is to achieve the dimming effect by changing the voltage waveform of the thyristor device; the working mode of the trailing edge dimmer is to achieve dimming by changing the voltage waveform through the MOS tube, and the line layout is relatively complicated and relatively cost-effective. Higher, the advantage is that the input voltage is unstable, it will not affect the dimming effect; there is no sound when dimming!
