Tanning bed 日晒床
(重定向自Sunbed)
A sunbed (British English), tanning bed (American English) or sun tanning bed is a device that emits ultraviolet radiation (typically 95% UVA and 5% UVB, +/-3%) to produce a cosmetic tan. Regular tanning beds use several fluorescent lamps that have phosphor blends designed to emit UV in a spectrum that is somewhat similar to the sun. Smaller, home tanning beds usually have 12 to 28 100 watt lamps while systems found in tanning salons can consist of 24 to 60 lamps, each of 100 to 200 watts.
