    摘要: A light source having first and second phosphor-converted component light sources is disclosed. The first component light source includes a first LED that emits light at a first wavelength and a first luminescent conversion material layer that converts light of the first wavelength to light of a first output wavelength, and the second component light source includes a second LED that emits light at a second wavelength and a second luminescent conversion material layer that converts light of the second wavelength to light of a second output wavelength that is different from the first output wavelength. The first and second LEDs are constructed in the same material system, preferably in the same batch of wafers on the fabrication line. A controller generates a current through each of the first and second LEDs that results in the light source generating light that is perceived to be a predetermined color.

    摘要: A light emitting device in which a primary light generator, such as a light emitting diode (LED) or laser diode, is operable to emit a primary light that is received by a body of wavelength converting material. A portion of the primary light is absorbed by the body of wavelength converting material and is emitted as secondary light. The wavelength converting material contains phosphor nano-particles and larger phosphor particles. The phosphor nano-particles prevent transmission of primary light while the larger phosphor particles provide efficient light conversion.
