    摘要: A light emitting device including a phosphor blend including four or more phosphors emitting within a specific spectral range to optimize the color rendering index (CRI) for a given color coordinated temperature (CCT). The blend will include at least four phosphors selected from the following: a blue phosphor having an emission peak at 400-500 nm, a green phosphor having an emission peak at 500-575 nm, an orange phosphor having an emission peak from 575-615 nm, and a deep red phosphor having an emission peak at 615-680 nm. The preferred blends are used to make light sources with general CRI values (Ra) greater than 95 at CCT's from about 2500 to 8000 K.

    摘要: A method for the manufacturing of white LEDs is proposed, which can achieve a tunable color rendering index (CRI) or luminosity through the use of at least two phosphor composition layers of essentially the same emission color coordinates, each composition including at least one individual phosphor compound. The method allows to optimize the devices for CRI at a given minimal luminosity requirement, or vice versa.
