FLUORESCENT LAMP SUBSTANTIALLY APPROXIMATING THE ULTRA-VIOLET SPECTRUM OF NATURAL SUNLIGHT

摘要

An improved suntanning fluorescent lamp having a spectral energy distribution of substantially UVA and UVB radiation. The spectral energy distribution substantially approximates natural sunlight below about 400 nanometers. Preferably, the lamp comprises a predetermined amount of a phosphor blend comprising cerium-activated strontium magnesium aluminate, europium-activated strontium pyrophosphate and europium-activated barium pyrophosphate.
