Light source with several white LEDs with different output spectra

摘要

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 blackbody radiation curve, said first component light source having an LED emitting light of a first wavelength and a first layer a first light-converting material that converts a part of this light into light of a second wavelength; a second component light source that emits light having a second color spot in the CIE 1931 color space diagram on the other side of the blackbody radiation curve, the second component light source having an LED that emits light of the first wavelength and a second layer of the first light converting Material that converts a portion of this light into light of the second wavelength; and an interface circuit that operates the first and second component light sources such that the solid state light source has a color point closer to the blackbody radiation curve than either the first or second color point, the interface circuit providing a first average current through the first component. Light source and setting a second average current through the second component light source, wherein the first average current differs from the second average current, wherein the component light sources are white LEDs with different output spectra.
