Abstract
Provided are methods and apparatus for combining light emitters and devices including the same. Embodiments include methods of selecting combinations of multiple light emitters that are grouped into multiple bins. The multiple bins correspond to multiple emitter group regions in a multiple axis color space and multiple luminosity ranges. Such methods may include prioritizing multiple combinations of light emitters from at least two of the bins, each of the combinations including chromaticity values corresponding to a desired color region and a luminosity value corresponding to a specified luminosity range.
