Abstract
The present invention includes a light source having N light generators, a receiver, and an interface circuit. Each light generator emitting light of a different wavelength, the intensity of light generated by the kgenerator is determined by a signal Icoupled to that light generator. The receiver receives a color coordinate that includes N color components, C, for k=1 to N, wherein N is greater than 1. The interface circuit generates the Ifor k=1 to N from the received color components and a plurality of calibration parameters. The calibration parameters depend on manufacturing variations in the light generators. The calibration parameters have values chosen such that a light signal generated by combining the light emitted from each of the light generators is less dependent on the manufacturing variations in the light generators than a light signal generated when Iis proportional to Cfor k=1 to N.
