1. A light source comprising:

  • N light generators, each light generator emitting light of a different wavelength, the intensity of light generated by the kth generator being determined by a signal Ik coupled to that light generator;

    a receiver for receiving a color coordinate comprising N color components, Ck, for k=1 to N, wherein N is greater than 1; and

    an interface circuit for generating Ik for k=1 to N from said received color components and a plurality of calibration parameters, said calibration parameters depending on manufacturing variations in said light generators and having values such that a light signal generated by combining said light emitted from each of said light generators is less dependent on said manufacturing variations in said light generators than a light signal generated when Ik is proportional to Ck for k=1 to N.
