Hot cathode of UV tube light 2 feet, made of high quality quartz. The average rated life of UV tube light 2 feet is 9000 hours. Different diameter (T5,T6,T8) of lamp ,aluminum and ceramic bases can be chosen.The 254nm (UV output) was tested in the laboratory.Two types of UV tube light 2 feet, one is emitting UV-C wavelength at 253.7nm, ozone-free of uv tube light 2 feet; the other is the uv tube light 2 feet emitting UV-C wavelength both at 253.7nm and 185nm, ozone-generating.
SCHOOLS AND KINDERGARTENS: UV tube light 2 feet for sterilization is used for classroom sterilization, to prevent cross infection and reduce morbidity.
HOSPITALS: ward sterilization, such as pediatric ward, obstetrics and gynecology ward, infectious ward, reduce cross infection, speed up the recovery of patients. Low-pressure UVC tube light for sterilization is installed at the door of the infectious disease ward to form ultraviolet door for long-term irradiation. UV tube light 2 feet for sterilization is used for sterilization in the vent to prevent the spread of bacteria to other areas and cause cross infection.
PUBLIC PLACE: in the public ventilation pipe installed in the amount of UVC tube light for sterilization, can send aseptic air to the room, prevent cross infection. UV tube light 2 feet for sterilization of reception room, meeting room, etc.
FOOD PROCESSING PLANTS: UV tube light 2 feet for sterilization of aseptic workshop, bacteria room, food processing workshop of food factory and storage room.
Low power density lamps, power density of 40 to 80W/cm, service life of 1000 hours or more. And high power density UV lamps, power density of more than 80W/cm, service life of 600 to 800 hours. UV lamp disinfection time is generally 30 minutes to an hour appropriate. Try not to exceed one hour, so as not to bring harm to the human body. According to the irradiation intensity of the UV light source, you can calculate the time needed to irradiate.
UV light is produced in a mercury discharge tube: an inert gas suspended in mercury vapor, a quartz tube containing two electrodes and an insulator. The mercury reaches a high point at 254 nm, 310 nm and 366 nm*, producing radiation between 200 and 400 nm.
Quartz intercepts the lower wavelengths and does not transmit any radiation below 230 nm. Each atom consists of a nucleus with many electrons floating in fixed orbits around it. After increasing the energy (electricity) electrons are brought in a higher orbit. Each element shows a tendency to return to its original situation.
