Abstract
The LED lamps replace traditional lamps is the direction of development domestic and abroad.It mainly introduced the LED lamp brightness control method from the aspect of software, then research and production of the LED efficient drive based on a IC chip digital boost constant current regulator, for the actual driving high power LED. It was realized 6 level control on the brightness of LED. The microcontroller controls D/A converter to make the output different voltage values through software programming, and then adjusts the DC/DC conversion circuit current size, finally implements LED brightness control. The experimental makes it possible to have the lamp with adjustable brightness, energy saving, achieve a wide range of voltage, current constant and so on. KeywordsLED lamp;Constant current drive;Single chip microcomputer ;digital boost constant current regulator.
