Description
Technical Field
The utility model relates to an ultraviolet ray disinfection equipment field, concretely relates to LED disinfection lamp that disinfects based on UVC and UVA dual wavelength gain.
Background
At present, the existing air is the basis for human survival, and we can select water and food, but can not select the surrounding air. When people breathe air, harmful substances enter the human body along with the air, and the human body is harmed. Especially, the pollutants in the indoor air can be continuously stacked and fermented in the room, and even become a toxic air chamber in the room after a long time. In recent years, new coronaviruses have rolled up around the world. In order to better cope with epidemic situations, the national market supervision and administration bureau and the national standard administration committee approve and issue 14 new national standards including 'requirement for sanitation of ultraviolet sterilizer' and 'requirement for general use of air disinfectant' in 9 months 4 in 2020. The standards are established by the organization of the national health and welfare agency and the national drug administration, and mainly relate to the key fields of epidemic prevention and control such as disinfectants, disinfection apparatuses, medical equipment and the like which are in urgent need. Currently, the global epidemic situation of new coronavirus pneumonia is still quite intense, and all parties are trying to find a method for resisting virus. Air is not an option but can be improved. In particular, in public places such as hospitals, markets, office buildings, airports and the like, because the space is relatively closed, people gather, the air is short of circulation, the risk of virus infection is high, and disinfection and sterilization are particularly important in the work of preventing and controlling epidemic situations. Compared with the traditional sterilization mode, the ultraviolet sterilization lamp has a more thorough sterilization effect and can inactivate microorganisms, thereby being beneficial to creating a safer indoor working environment. The ultraviolet ray has the characteristic of broad-spectrum sterilization, and has very obvious sterilization effect and very high efficiency regardless of various microorganisms such as bacteria, viruses, algae, spores and the like. Compared with other sterilization modes, the ultraviolet sterilization has the advantages that after the irradiation is finished, the ultraviolet is not turned off, and the participation and the pollution of chemical processes are avoided. At present, the ultraviolet sterilization light source mainly comprises a mercury lamp and a UV-LED. UV, i.e. Ultraviolet light, is an electromagnetic wave with a wavelength between 10nm and 400 nm. UV can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) of microorganisms, so that bacteria can die or cannot reproduce, and the aim of sterilization is fulfilled. The UV is classified into UVA, UVB and UVC according to the wavelength. Among them, the deep Ultraviolet (UVC) wavelength with a wavelength of 200 to 280nm is the most suitable wavelength for sterilization, and has been widely used for sterilization. And the shorter the wavelength is, the higher the sterilization efficiency is, but the relative harm to human body is also higher, so the mainstream wave band of the current chip factory falls in 265-280 nm. The ultraviolet disinfection technology is based on modern epidemic prevention science, medicine and photodynamics, and utilizes specially designed UV wave band ultraviolet light with high efficiency, high intensity and long service life to irradiate flowing water so as to directly kill various bacteria, viruses, parasites, algae and other pathogens in the water, thereby achieving the aim of disinfection. Compared with a mercury lamp, the UV-LED disinfection lamp has higher safety. First, mercury lamps contain mercury, which is a harmful substance. The mercury lamp tube is made of quartz glass, and once the mercury lamp tube is broken, mercury leakage is caused, and the mercury lamp tube is very dangerous. Second, the mercury lamp generates 185nm radiation, which chemically reacts ambient oxygen molecules to form ozone. Ozone has a certain adverse effect on the atmosphere and the health of people. Compared with a mercury lamp ultraviolet lamp, the UV-LED lamp has higher energy density, is convenient to use in a small-size closed space, can realize human-computer coexistence, overcomes the defect that personnel and animals need to be emptied in the working process of the traditional mercury lamp ultraviolet lamp, and enables the application of the UV-LED lamp to have a huge imagination space. Furthermore, with modern LED technology, UV-LEDs can not only replace existing light sources, but also open up a wider range of applications, since it can be customized to the different requirements of different chemical and biological processes. Thus, UV-LEDs are more advantageous and a new solution. In addition, the UV-LED is small and exquisite, and can be made into a small module or a single light source to be installed in a narrow and compact space. At present, the UV-LED is favored by suppliers of portable sterilization bags and sterilization boxes due to safety and environmental protection, and occupies a certain market in the field of small space or surface sterilization.
