  • Optimized phosphor system for improved efficacy lighting sources
    Patent number: 7119488
    Abstract: A fluorescent lamp including a phosphor layer comprising a phosphor blend including four or more optimized phosphors emitting within a specific spectral range to optimize luminosity for a given color rendering index (CRI) and color coordinated temperature (CCT). The blend will include at least four phosphors selected from the following: a blue phosphor having an emission peak at 440–490 nm, a blue-green phosphor having an emission peak at 475–525 nm, a green phosphor having an emission peak at 515–550 nm, an orange phosphor having an emission peak from 550–600 nm, a deep red phosphor having an emission peak at 615–665 nm, and a red phosphor having an emission peak at 600–670 nm.
