What Are The Triac Dimmer, LED 0-10v Dimming, PWM Dimming?
Triac Dimmer
The most common LED dimmers are phase-cutting dimmers.
All phase-cutting dimmers work by switching the AC mains supply to the LED lamp on and off twice in every mains cycle. This has the effect of reducing the flow of electrical energy to the LED lamp or fixture, so reducing its light output.
LED 0-10v Dimming
LED technology is getting popular every day for commercial as well as residential lighting. Due to its popularity, the 0-10V dimming system is also getting much attention to control and maximize the light output of an LED fixture.
0-10V LED dimmer uses the DC voltage to control the output of the light fixture. This is one of the most straightforward and earliest lighting control systems. 0-10V dimming allows the smooth operation of light and dimming at the light levels of 10%, 1%, and 0.1%.
PWM Dimming
PWM dimming achieves the same effect by varying the duty cycle of a constant current in the string to effectively change the average current in the string. Pulse-width modulation (PWM) is a common type of dimming used to adjust the current in white-LED driver devices. PWM dimming takes a rectangle waveform with a variable positive duty cycle (D) and adjusts the LED current proportionally.
The two key parameters in PWM dimming are the duty cycle and frequency.
