Abstract

Systems and methods for compensating, controlling, mixing and saturating/desaturating colors produced by or emitted from LED artificial light sources through use of multiple channel, LED controllers to control the proportion of constituent colors each to the other, to control the intensity level of the total light output of the mixed, desaturated light during and after color mixing and/or saturation/desaturation by simultaneously increasing and decreasing power to the constituent color LEDs at the same rate, and once a desired color has been produced, changing the intensity/brightness and/or degree of saturation of the produced color without changing the hue of the produced color.

Claims6

Dependent claims

A method for color mixing of constituent LED light sources to produce a predetermined resulting color at a predetermined intensity comprising:

providing a first LED light source of a first predetermined color and having a first intensity;
providing a second LED light source of a second predetermined color and having a second intensity;
providing a controller adapted to control current to the first LED light source, to control current to the second LED light source and adapted to simultaneously decrease and increase current to the first LED light source and to the second LED light source, respectively;
increasing current to the second LED light source and simultaneously decreasing current to the first LED light source until the predetermined resulting color is produced at said first intensity.
