Abstract

A psychophysical experiment was carried out to evaluate the glare, brightness, whiteness and hue composition of a glare source made by a multiple-channel LED lighting system. About 80 stimuli were produced to cover a large colour gamut at two luminance levels, 280 and 2400 cd/m 2, respectively. The results were used to verify the earlier CAM15u colour appearance model and the QUGR glare model. A revised model, CAM15uz, is refined from CAM15u by adding an effect of hue to the prediction of brightness caused by the Helmholtz–Kohlrausch effect. In addition, a new hue composition scale is established.
