Abstract:
LED lighting systems include LEDs of at least two different colors, a reflective layer and a diffusion layer. The reflective layer has a transmittance-to-reflectance ratio that is configured to homogenize intensity of the light emitted from the LEDs. The diffusion layer is configured to homogenize color uniformity of the light.
