Patent ID: 8771029

Claim:
A method of fabricating a light source, the method comprising: obtaining at least two sets of visible-light emitters, each set of emitters having a primary color; and configuring the at least two sets of visible-light emitters using a plurality of test color samples including more than fourteen test color samples resolved by an average human eye as different and a reference light source dissimilar from the at least two sets of visible-light emitters, by performing a method comprising: selecting at least one of: the primary colors or relative fluxes generated by each set of emitters to maximize a number of the plurality of test color samples for which, when illuminated using the light source having a predetermined correlated color temperature instead of the reference light source having the same correlated color temperature: chromaticity shifts resulting from use of the light source instead of the reference light source are preserved within corresponding regions of a chromaticity diagram, each region defined by a color at a center of the region and a predetermined chromaticity variation value from the color at the center of the region; and lightness shifts resulting from use of the light source instead of the reference light source are preserved within a predetermined lightness variation value.
