Abstract
Systems and methods for using an expert system to develop a color model for and LED-based lamp for reproducing a target light and calibrating the lamp are disclosed. The CCT of light generated by the lamp is tunable by adjusting the amount of light contributed by each of the LED strings in the lamp. The target light is decomposed into different wavelength bands, and light generated by the LED-based lamp is also decomposed into the same wavelength bands and compared. A color model for the lamp provides information on how hard to drive each LED string in the lamp to generate light over a range of CCTs, and the color model is used to search for the appropriate operating point of the lamp to reproduce the target light.
