Abstract
We analyze the effects on color uniformity of the near-field light distribution due to different cluster configurations (at optimum packaging density for uniform irradiance) of light sources using mixed red, green and blue (RGB) light emitting diodes (LEDs). A photometric analysis and experimental results that show the near-field performance that can be achieved with several cluster configurations of multicolor LEDs is presented. Contour maps for the color variation (in reference to illuminant D65) in function of spatial coordinates of light distribution are given.
