| Title: |
Pre-Configured Light Modules |
| 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 k.sup.th
generator is determined by a signal I.sub.k coupled to that light
generator. The receiver receives a color coordinate that includes N color
components, C.sub.k, for k=1 to N, wherein N is greater than 1. The
interface circuit generates the I.sub.k for 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 I.sub.k is
proportional to C.sub.k for k=1 to N.
