Abstract

Red–Green–Blue (RGB) Light Emitting Diodes (LEDs) are finding widespread use due to recent advances in the LED technology. LEDs are increasingly being used in LED displays, automobiles, traffic lights, and general-purpose lighting. With the advantage of a full colour range of the high power LEDs, more advanced architectural designs and stage and studio lighting are developing. In this paper, a digital controller based RGB driver was designed to operate the LEDS in different colour temperature to get different white colours for applications like seminar halls, stage, studio and architecture lighting. The proposed driver maintains the minimum drive voltage across the LEDs and current controllers required to keep it in regulation by selecting the minimum drain voltage of the MOSFETs of the current controllers
