Abstract:
1. A method of grouping a plurality of light emitters, comprising: selecting a first portion of the plurality of light emitters using a first region of a multiple axis color space that includes International Commission on Illumination (CIE) 1976 and that is configured to represent each of a plurality of colors as at least two chromaticity coordinates, the region proximate a predefined point on the multiple axis color space and comprising a major axis including a first length and a minor axis including a second length that is less than the first length; and selecting a plurality of other portions of the plurality of light emitters using a plurality of other regions and having a substantially similar size and shape as the first region, at least one of the plurality of other regions being adjacent the first region, wherein at least one of selecting the portion of the plurality of light emitters or selecting the plurality of other portions of the plurality of light emitters is performed using at least one processor, wherein the major axis is oriented substantially 10 degrees clockwise from a vertical axis of the multiple axis color space, and wherein the first region and the plurality of other regions correspond to a portion of the multiple axis color space in which chromaticity color coordinate u′ is in a range of about 0.13 to about 0.30 and chromaticity coordinate v′ is in a range of about 0.36 to about 0.55.
