Abstract
One embodiment of a system for illuminating multiple LEDs has a plurality of LEDs and a controller programmed to provide a plurality of serial binary signals, each of which drives a respective one of the plurality of LEDs. Each of the serial binary signals has a series of pulses with each of said plurality of LEDs emitting light during each pulse of its respective one of the serial binary signals. The emitting intensity of each of the plurality of LEDs depends on the number of pulses in its respective one of the serial binary signals, wherein the light from the plurality of LEDs combines to emit a color of light.
