WARM WHITE LEDS HAVING HIGH COLOR RENDERING INDEX VALUES AND RELATED LUMINOPHORIC MEDIUMS |
摘要 |
Light emitting devices include a solid state lighting source and a recipient luminophoric medium for down-converting at least some of the radiation emitted by the solid state lighting source. The recipient luminophoric medium includes a first material that down-converts the radiation emitted by the solid state lighting source to radiation having a peak wavelength in the green color range that has a full width half maximum emission bandwidth that extends into the cyan color range, and at least one additional material that down-converts the radiation emitted by the solid state lighting source to radiation having a peak wavelength in another color range.
