  • Methods for combining light emitting devices in a package and packages including combined light emitting devices
    Patent number: 8333631
    Abstract: Methods of forming a light emitting device package assembly include defining a chromaticity region in a two dimensional chromaticity space within a 10-step MacAdam ellipse of a target chromaticity point, and subdividing the defined chromaticity region into at least three chromaticity subregions, providing a plurality of light emitting devices that emit light having a chromaticity that falls within the defined chromaticity region, selecting at least three of the plurality of light emitting devices, wherein each of the three light emitting devices emits light from a different one of the chromaticity subregions. The at least three light emitting devices are selected from chromaticity subregions that are complementary relative to the target chromaticity point to at least one other chromaticity subregion from which a light emitting device is selected.
