ABSTRACT:
A solid state light source having first and second component light sources and an interface circuit and a method for making the same are disclosed. The first and second component light sources emit light having first and second color points on different sides of the black body radiation curve. The first and second component light sources include LEDs that emit light of a first wavelength and a layer of a light converting material that converts a portion of that light to light of a second wavelength. The interface circuit powers the first and second component light sources such that the solid state light source has a color point that is closer to the black body radiation curve than either the first or second color points. A third component light source can be included to expand the range of white color temperatures that can be reached by the light source.
