Abstract: Good lighting quality plays a key role in an interior environment. In order to maintain and comforting environment for the occupants it becomes crucial to maintain appropriate lighting. This study illustrates an LED colour control algorithm which modifies illuminance and colour temperature according to daylight. The combination of six different colours of LEDs, i.e., red, green, blue, amber, lime and white (2200 K) creates white light. It aims to illuminate indoor spaces to mimic daylight. Daylight changes over a range of colour temperatures. The colour mixing algorithm varies the LED luminance ratios and with the combination of both natural light and artificial lights the room is illuminated, thereby, saving the overall energy consumption without compromising quality of light.
