摘要:
A fluorescent lamp (10) including a phosphor layer (16) 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.

In a light wavelength conversion member 16, a translucent 30 encapsulates a yellow phosphor 32 and a blue phosphor 34. The yellow phosphor 32 is excited by light ranging from near-ultraviolet light to short-wavelength visible light whose dominant wavelength is 350 nm to 480 nm and then emits yellow light. The blue phosphor (34) is excited by light ranging from near-ultraviolet light to short-wavelength visible light whose dominant wavelength is 350 nm to 480 nm and then emits blue light. The difference in refractive index between each of the yellow phosphor 32 and the blue phosphor 34 and the translucent member 30 is less than or equal to 0.2.
摘要:
A mercury-free discharge composition may be provided. The ionizable mercury-free discharge composition may include gallium and a halogen. The composition may be capable of emitting radiation if excited, and the composition may produce a total equilibrium operating pressure less than about 100,000 Pascals if excited. A mercury-free discharge lamp (20) may be provided. The mercury-free discharge lamp may include an envelope (22); an ionizable discharge composition including gallium contained by the envelope (22); and a phosphor composition contained by the envelope (22) and in communication with the ionizable discharge composition.
