A light source capable of simulating CIE D Illuminants was developed based on different coloured LEDs. A model was also devised to construct the spectral power distribution (SPD) of a CIE illuminant by mixing different coloured LEDs at different intensities. The performance of the LED simulators, was evaluated in terms of correlated colour temperature (CCT), colour rendering index (CRI), metamerism index (MI) and stability.
