White-light generation efficiency

Photolumincscence is used in fluorescent lamps. This application was even used before the Second World War. The lamp consists of a glass tube in which a low-pressure mercury discharge generates ultraviolet radiation (85% of this radiation consists of 254 nm radiation). The lamp phosphor (or a mixture of lamp phosphors) is applied to the inner side of the tube. This phosphor converts the ultraviolet radiation into white light. The efficiency of conversion of electricity to light is in a fluorescent lamp considerably higher than in an incandescent lamp. [Pg.4]
