Grading LED illumination : from colour rendering indices to specific light quality indices

摘要：

Two experiments were designed and conducted with observers to grade the quality of light-emitting diodes (LED) illumination. The first one was based on colour discrimination. The second one was based on the judgement of colourfulness.We conclude that clusters with red, green, blue, and/or amber LEDs do not allow satisfactory colour discrimination. Although they seem to locally enhance the colour gamut, they impair colour discrimination. We also conclude that LED clusters that include white LEDs plus a few correcting colour LED may render colours faithfully.
