Abstract:
Chromaticity of light output by a light-emitting diode, such as a light-emitting diode (LED), is adjusted while maintaining a brightness of the illumination source substantially constant by adjusting a drive schema for the illumination source. A driver for LEDs or other light-emitting diodes provides for varying a drive schema to adjust chromaticity of driven LEDs.
