uv light source for uv light sterilization

UV germicidal lamp is one of mercury lamp, in which the excited mercury atoms can different wavelengths characteristics when transition. The human eye can not see ultraviolet light of 100nm-400nm UV wavelength.

100-400nm wavelength of UV, according to their function and effect on human, can be divided into UV-A, UV-B, UV-C and V-UV. 254nm wavelength UV-C destroy microorganisms effectively, such as DNA structure of bacterial and viruses to achieve sterilization purposes.

VUV 185nm of 100-200nm wavelength can produce ozone, and ozone can also achieve sterilization and eliminating taste effects. 185nm wavelength can aslo hydrolysis organic moleules in water as well as producing hydrogen, oxygen, free radicals. It ultimately oxidize organic molecules.

The using life of high-quality UV lamp is 9000-13000hours. The UV lamp needs a professional ballast to ensure the using life and efficiency of lamp. Directly exposuring in intense ultraviolet light will make the skin or eyes burning. Therefore it is necessary to take protective measures in the maintenance of UV germicidal lamps.
