    摘要： Mercury vapor discharge fluorescent lamps are provided. The lamp (10) can include a lamp envelope (12) enclosing a discharge space and having an inner surface. First and second electrodes (18) can be positioned on the lamp (10), such as on opposite ends of the lamp envelope (12). An ionizable medium that includes mercury and an inert gas can be within said lamp envelope (12). A phosphor layer (16) can be on the inner surface of the lamp envelope (12). The phosphor layer (16) generally includes a phosphor blend of a calcium halophosphor, a blue phosphor having an emission peak at about 440 nm to about 490 nm, a blue-green phosphor having an emission peak at about 475 nm to about 530 nm, and a red phosphor having an emission peak at about 600 nm to about 650 nm.

    摘要： A fluorescent lamp (10) is provided including a five phosphor blend (16) comprising four rare earth phosphors, including BAMn, and a non-rare earth white halophosphate phosphor. This phosphor blend (16) provides a lamp (10) that exhibits high color rendering index (CRI), of at least about 85, i.e. at least 87, while simultaneously achieving good lumen output, or lumens per watt (LPW), of at least about 70, i.e. at least 75, at all CCTs, and particularly at lower CCT of between about 3000K and 4100K. The phosphor system provided includes a rare earth-doped red emitting phosphor, a rare earth-doped blue emitting phosphor, a rare earth-doped green-blue emitting phosphor, a rare earth-doped green emitting phosphor and a non-rare earth white halophosphate phosphor.
