ABSTRACT

The configuration of polychromatic sources of white light, which are composed of at least two groups of colored emitters, such as light-emitting diodes (LEDs), is disclosed. Based on a novel approach of the assessment of quality of white light using, for example, 1269 test color samples from the enhanced Munsell palette, the spectral compositions of light, such as white light, composed of two to five (or more) narrow-band emissions with the highest number of colors relevant to human vision rendered almost indistinguishably from a reference source, such as a blackbody radiator, are introduced. An embodiment of the current invention can be used, in particular, for configuring polychromatic sources of white light with the ultimate quality capable of rendering of all colors of the real world.
