Drivers with dimming capability can dim the LED light output over the full range from 100% to 0%. Dimming drivers can dim LEDs by reduction in the forward current, pulse width modulation (PWM) via digital control, or more sophisticated methods. Most dimming drivers operate using the PWM method. With this method, the frequency could range from a hundred modulations per second to as high as hundreds of thousands of modulations per second, so that the LED appears to be continuously lighted without flicker.
At present, the most commonly used LED dimming power: LED thyristor dimming power, LED 0 / 1-10V dimming power, PWM dimming power supply. Other dimming works by controlling the current and voltage, the frequency of the output to achieve the LED dimming function.
