The theory of led controllerAbout the theory of led controller ,it had been switch. to control the open and close of current through the switch.the processof getting LED workdone is The theory of led controller. the switchcan use that mechanical or lectronics or MCU to realize process of controlling.

It seem simply, but it’s not all. to guarantee that it can adjust bright during conditions of normal operation. this is difficult. The swiche constant current have to be faced. the switch speed is most import factor.Slow opening speed can lead problem that illumination was uneven and flash of led.
