Abstract: Systems and methods of Planckian and non-Planckian dimming of solid state light sources are disclosed. For a given first range of correlated color temperature values on the 1931 CIE Chromaticity Diagram, the current through a plurality of solid state light sources is adjusted so that the light output thereby follows the correlated color temperature values relating to the black body curve over that given first range. For a given second range of correlated color temperature values, the current through a plurality of solid state light sources is adjusted so that the light output thereby deviates from black body curve and instead relates to a series of coordinates that tracks a line between the curve and a color point for one of the solid state light sources.
