Patent ID: 7568815

Claim:
A solid state light source comprising: a first component light source that emits light having a first color point in the CIE 1931 color space diagram on one side of the black body radiation curve, said first component light source comprising an LED that emits light of a first wavelength and a first layer of a first light converting material that converts a portion of that light to light of a second wavelength; a second component light source that emits light having a second color point in the CIE 1931 color space diagram on the other side of said black body radiation curve, said second component light source comprising an LED that emits light of said first wavelength and a second layer of said first light converting material that converts a portion of that light to light of said second wavelength; and an interface circuit that powers said first and second component light sources such that said solid state light source has a color point that is closer to said black body radiation curve than either said first or second color points, wherein said interface circuit sets a first average current through said first component light source and a second average current through said second component light source, said first average current being different from said second average current.
