POLYCHROMATIC SOLID-STATE LIGHT SOURCES FOR THE CONTROL OF COLOUR SATURATION OF ILLUMINATED SURFACES

Polychromatic light sources of white light are composed of at least two different coloured emitters, such as groups of light-emitting diodes (LEDs). Disclosed are the spectral power distributions and relative partial radiant fluxes of the coloured emitters that allow controlling the colour saturatin...

More Information
Summary:Polychromatic light sources of white light are composed of at least two different coloured emitters, such as groups of light-emitting diodes (LEDs). Disclosed are the spectral power distributions and relative partial radiant fluxes of the coloured emitters that allow controlling the colour saturating ability of the generated light, namely, the ability to render colours with increased saturation and the ability to render colours with decreased saturation. Also disclosed is a method for dynamical tailoring the colour saturating ability of the generated light.
