IntroducTIonThis paper describes the various methods of driving the high power and high brightness LED. The task of designing an LED based system involves the following selecTIon.I. number of LED used and the connecTIon scheme between LEDsII. linear or switch mode LED driverIII. power supply source i.e. DC voltage or AC mains or batteryIV. opTIcal subsystem, e.g. lens, filter cover etc.The number of LED needed depends on the luminance required and the current the LEDs are driven.The optical subsystem is not covered here as it is beyond the scope of this paper.
