20130234602 | SYSTEM AND METHOD FOR COLOR TUNING LIGHT OUTPUT FROM AN LED-BASED LAMP - 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. | 09-12-2013 |
20140167617 | SYSTEM AND METHOD FOR COMMUNICATION AMONG LINEAR LIGHT MODULES IN A LIGHTING SYSTEM - Light source systems and methods of operating the light source systems are disclosed. A light source system may include a combination of two lighting modules in communication with each other. The lighting modules can operate in concert, in parallel, or as master or slave. A printed circuit board assembly (PCBA) of the light source system includes electrical circuitry to drive a set of light emitting diodes (LEDs).
