Abstract
Systems and methods for controlling the output of a plurality of light sources. The system can include four or more light sources (e.g. light emitting diodes ('LEDs')) and a controller. The light sources are included in, for example, a luminaire. The respective outputs of the plurality of light sources are controlled using a hue and purity ('HP') control technique. The HP technique includes selecting a dominant hue (e.g., green, blue, red, etc.). The purity of the selected hue is then modified to include or remove wavelengths of light adjacent to the selected hue. For example, if the selected hue is green, gradually reducing the purity of the selected hue gradually increases the presence of cyan and amber in the output of the luminaire. As the purity is reduced further, additional wavelengths of light are included, but the output of the luminaire remains, in essence, green.
