Abstract:
The current invention discloses polychromatic sources of white light, which are composed of at least two groups of colored emitters, such as light-emitting diodes (LEDs) are disclosed. Based on a novel approach of the assessment of quality of white light using 1269 test color samples from the enhanced Munsell palette, the spectral compositions of 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 blackbody radiator are introduced. An embodiment of the current invention can be used, in particular, for designing polychromatic sources of white light with the ultimate quality capable of rendering of all colors of the real world.
