ABSTRACT:
A light source that generates light that is perceived to have a predetermined color is disclosed. The light source includes first and second red LEDs and a non-red light emitter. The first and second red LEDs emit light in the red portion of the spectrum but at different wavelengths. The non-red light emitter emits light at a wavelength in a non-red portion of the spectrum. A controller varies the intensity of the first and second red LEDs to provide a combined light signal that is perceived as having the predetermined color. In one embodiment, the non-red light emitter includes a fluorescent light, and the controller adjusts the intensities of the red LEDs to provide a source that is perceived as an incandescent source of a predetermined color temperature.
