UV germicidal lamp, also known as ultraviolet disinfection lamp, UV germicidal lamp uses the ultraviolet light emitted by mercury lamp to achieve sterilization and disinfection function, ultraviolet disinfection technology has unparalleled sterilization efficiency of other technologies, sterilization efficiency can reach 99%~99.9%.
The scientific principle of ultraviolet disinfection: it mainly acts on the DNA of microorganisms, destroys the DNA structure, and makes it lose the function of reproduction and self-replication to achieve the purpose of sterilization and disinfection. Ultraviolet sterilization has the advantage of colorless, odorless and no chemical residue. However, if there are no protective measures, it is easy to cause great harm to the human body. If the exposed skin is irradiated by this kind of UV germicidal lamp, the light will appear redness, itching, desquamation; Severe cases can even cause cancer, skin tumors and so on. At the same time, it is also the eye's "invisible killer", can cause conjunctival, corneal inflammation, long-term exposure may lead to cataracts.
Many schools and kindergartens, in order to prevent the spread of infectious diseases, have installed UV germicidal lamps in the classroom for sterilization, but the UV germicidal lamps can not be opened when someone leaves, only after the people can open sterilization. When installing the UV germicidal lamp, the novice electrician should indicate on the lamp of the UV germicidal lamp to attract the attention of the indoor personnel. When installing the control switch of the UV germicidal lamp, it can not be installed in accordance with the provisions of the general switch, nor can it rely on the method of handing over the attention of the operator, and it can not be attached to the switch board with a small note for instructions. The switch for controlling the UV germicidal lamp should be installed separately in a lockable box, and the key should be managed and controlled by a special person, and the management matters of the UV germicidal lamp should be posted outside the box for controlling the UV germicidal lamp, indicating the use and harm of the UV germicidal lamp, and relying on everyone's supervision and management.
