Abstract
Methods of forming a light emitting device package assembly include defining a chromaticity region in a two dimensional chromaticity space, 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 at least one of the defined chromaticity subregions, selecting at least three of the plurality of light emitting devices, each of the three light emitting devices emits light from a different one of the chromaticity subregions, and mounting the selected light emitting devices on a light emitting device package body.
Claims21
A method of forming a light emitting device package assembly, comprising:
- providing a light emitting device package body;
- defining a chromaticity region in a two dimensional chromaticity space, 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;
- and
- mounting the selected light emitting devices on the light emitting device package body.
A light emitting device package assembly, comprising:
- a light emitting device package body;
- and
- at least three light emitting devices on the package body, wherein each of the at least three light emitting devices emits light having a chromaticity that falls within a defined chromaticity region in a two dimensional chromaticity space, the defined chromaticity space being larger than and encompassing a defined bin in the two dimensional chromaticity space and being subdivided into at least three subregions;
- and
- wherein each of the at least three light emitting devices emits light that falls within a different one of the at least three subregions of the defined chromaticity region, and wherein at least one of the light emitting devices emits light that falls outside the defined bin.
