Abstract
The present disclosure relates to shifting a chromaticity of light generated from a light-emitting device. A light-emitting device may incorporate an optical element (e.g., filter) so that light emitted from a light-generating surface having an initial chromaticity may be altered. The optical element may shift the chromaticity of emitted light having the initial chromaticity to a final chromaticity that is different from the initial chromaticity. Thus, the chromaticity of emitted light from the manufactured LEDs that would otherwise be unacceptable for having chromaticity coordinates that fall outside of a desired chromaticity bin is shifted so as to have chromaticity coordinates that fall within suitable parameters. Accordingly, a number of the manufactured LEDs that would normally be discarded may be salvaged.
