Abstract
Systems and methods for using an LED-based lamp for reproducing a target light are disclosed. A color-space searching technique is introduced here that enables the LED-based lamp to be tuned to generate light at a specific CCT 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. The color-searching techniques allow the LED-based lamp to closely emulate a black body radiator given the limitations of the physical specification of color string in the LED strings.
