Patent Number: 7026769 
Title: Luminary Control System Adapted For Reproducing The Color Of a Known Light Source 
Abstract: A light source and method for programming the light source to provide a color that approximates that of a target light source are disclosed. The light source generates light at first and second wavelengths with intensities that are determined by first and second control signals that are set by a feedback controller that matches the outputs of a monitoring circuit to target signals. The target signals are generated from target values that are entered into the feedback controller by exposing the light source to the target light source and observing the outputs from a set of photodetectors incorporated in the light source. In one embodiment, the photodetectors in the monitoring circuit are used for this programming function.
