摘要 |
An enhanced UV-emitting fluorescent lamp is described that provides a UV spectral emission for simultaneously tanning of the human skin and promotion of vitamin D production in the human body. The lamp contains a phosphor layer having a phosphor blend of three rare-earth-activated phosphors: SrB4O7:Eu, LaPO4:Ce and YPO4:Ce. Preferably, the phosphor blend comprises 25-27% SrB4O7:Eu, 23-26% LaPO4:Ce, and 47-52% YPO4:Ce by weight. |
