A low-pressure mercury lamp that generates ultraviolet light for sterilization purposes. Ultraviolet light with a wavelength of around 2600 Å has strong sterilizing power, and ultraviolet light with a wavelength of 1850 Å or more is not absorbed by air, making it suitable for sterilizing airborne microorganisms. The sterilizing effect of ultraviolet light is superficial and does not reach deep areas or shadows, so it is necessary to generate ozone in moderation. Germicidal lamps are easy to use, so they are widely used in operating rooms, hospital rooms, examination rooms, sterile rooms, food processing plants, kitchens, etc. to prevent hospital infections. Ultraviolet light is harmful to the skin and eyes of the human body, so care must be taken when using it.

殺菌の目的で紫外線を発生させる低圧水銀灯。 2600Å付近の波長の紫外線が殺菌力が強く,また,1850Å以上の紫外線は空気によって吸収されないので,空中の微生物の殺菌に適している。紫外線による殺菌作用は表面的であり,深部や陰の部分には及ばないので,適度にオゾンを発生する必要がある。殺菌灯の使用法は簡単なため,病院内感染を防止するなどのために手術室,病室,診察室,無菌室,食品加工場,台所などに広く利用される。紫外線は人体の皮膚,眼に害作用があるので,使用に際しては注意する必要がある。
