Introduction Of UV Disinfection Lamp

Ultraviolet lamps, also called ultraviolet disinfection lamps, use the ultraviolet light emitted by mercury lamps to achieve sterilization and disinfection functions. Ultraviolet disinfection technology has unparalleled sterilization efficiency of other technologies, and the sterilization efficiency can reach 99% to 99.9%. The scientific principle of ultraviolet disinfection: It mainly acts on the DNA of microorganisms, destroys the structure of DNA, and makes it lose the function of reproduction and self-replication, so as to achieve the purpose of sterilization and disinfection. Ultraviolet sterilization has the advantages of being colorless, odorless, and chemical-free. But if there is no protective measures, it is very easy to cause huge harm to the human body. If exposed skin is irradiated by this type of ultraviolet light, redness, swelling, itching, and desquamation may occur in mild cases; cancer and skin tumors may even occur in severe cases. At the same time, it is also the "invisible killer" of the eyes, which can cause inflammation of the conjunctiva and cornea, and long-term exposure may cause cataracts.

In order to prevent the spread of infectious diseases, many schools and kindergartens have installed ultraviolet lamps in their classrooms for sterilization. However, it is stipulated that ultraviolet lamps cannot be turned on when there are people, and can only be turned on after people leave. When installing UV lamps, novice electricians should indicate on the lamps of the UV lamps to attract the attention of indoor personnel. When installing the control switch of the ultraviolet lamp, it cannot be installed in accordance with the general switch regulations, nor can it rely on the method of giving the operator's attention, and it is not allowed to paste a small note on the switch board for instructions. The switch that controls the UV lamp should be installed separately in a lockable box. The key should be managed and controlled by a dedicated person. The management items of the UV lamp should be posted outside the box that controls the UV lamp to remind the usefulness and use of the UV lamp. Hazards, rely on everyone's supervision and management.
