Abstract
A new Monte Carlo simulation as a tool for analysing colour feedback systems is presented
here to analyse the colour uncertainties and achievable stability in a multicolour dynamic LED
system. The Monte Carlo analysis presented here is based on an experimental investigation
of a multicolour LED light engine designed for white tuneable studio lighting. The measured
sensitivities to the various factors influencing the colour uncertainty for similar system are
incorporated. The method aims to provide uncertainties in the achievable chromaticity
coordinates as output over the tuneable range, e.g. expressed in correlated colour
temperature (CCT) and chromaticity distance from Planckian locus (Duv), and colour
rendering indices (CRIs) for that dynamic system. Data for the uncertainty in chromaticity is
analysed in the u', v' (Uniform Chromaticity Scale Diagram) for light output by comparing the
variations in chromaticity differences with the “n – step u′ v′ circles” as defined in CIE
TN001:2014.
