Abstract
The quality of light emitted by lighting systems based on high brightness LEDs is studied using colorimetric parameters (chromaticity coordinates, correlated colour temperature and colour rendering index) when operating with different forms of electrical power supply (continuous and pulsed current). Uncertainties, calculated by Monte Carlo simulations applied to relative spectral measurements and colorimetric parameters are presented.Keywords
