The ultraviolet germicidal lamp is a low-pressure mercury lamp. The low-pressure mercury lamp is activated by using lower-pressure mercury vapor to emit ultraviolet light, and the two main emission lines are: one is 253.7nm wavelength; the other is 185nm wavelength, both of which are ultraviolet light invisible to the naked eye. The germicidal lamp does not need to be converted into visible light, the wavelength of 250-260 nm can play a good role in sterilization, and the wavelength interval can damage chromosomes of the germicidal lamp and play a photochemical role.

The scientific principle of ultraviolet disinfection: mainly acts on the DNA of microorganisms to destroy the structure of the DNA, so that the DNA loses the functions of reproduction and self-replication, thereby achieving the aims of sterilization and disinfection.

The ultraviolet sterilization has the advantages of no color, no smell and no chemical substance left. But if no protective measures are taken, the human body is extremely easy to be greatly injured. If the naked skin is irradiated by the ultraviolet lamp, the mild person can have red swelling, pain and itch and desquamation; even serious cases may cause canceration, skin tumor, etc. Meanwhile, it is also an 'invisible killer' of eyes, which can cause conjunctiva and cornea inflammation, and cataract can be caused by long-term irradiation.

The ultraviolet lamp 30 is disposed on the surface of the LED lamp panel.

The ultraviolet lamps 30 and the LED lamps are arranged on the LED lamp panel in a staggered mode.

The control unit 40 has a microprocessor unit 50, a starting unit 60 connected to the microprocessor unit 50, a timing unit 70 and an air quality detecting unit 80, wherein the air quality detecting unit 80 is used for detecting the air quality in the environment, the starting unit 60 starts or stops the ultraviolet lamp 30, and the timing unit 70 is used for calculating the working time of the ultraviolet lamp 30 and sending the working time to the LED display module 20 for display.

The ultraviolet ray sterilizing lamp radiates ultraviolet rays with the wavelength of 253.7nm outwards. The ultraviolet ray has the strongest sterilizing capability, and can be used for sterilizing water, air, clothes and the like. Ultraviolet sterilizing lamps of 15W, 20W, 30W and 40W, using a voltage of 220V, are commonly used for sterilizing personnel, and are generally installed in disinfection dressing rooms, veterinary rooms and laboratories.

The ultraviolet ray disinfection lamp irradiates for about 5min to kill bacteria and viruses carried on clothes. It can also be used for air sterilization in laboratory and operating room requiring clean air, and can kill bacteria in air by irradiating for about 30 min.
