Abstract
In an LED dimming and driving method and its circuit, a receiver, a current source and a controller are installed in a dimming module, and after the receiver has received a dimming signal, the current source is driven to output a current with a magnitude corresponsive to the dimming signal, and then after the controller has converted the current into a voltage level by a terminal resistor, the magnitude of the driving current of the LED is adjusted according to the voltage level to improve a linear dimming accuracy.
