Abstract
A lighting device producing white light having a target color correlated temperature (CCT) value includes an LED array having one or more red LEDs, one or more warm white LEDs, and one or more cool white LED; one or more photo-luminescent materials for shifting the CCT value of the light emitted from the cool white LED toward a green CCT value and/or the CCT value of the light emitted from the warm white LED toward a yellow CCT value; and a waveguide material having a mixing region for mixing the shifted and unshifted light so as to generate white light having the target CCT value and an output region for outputting the white light.
