Description
Technical Field
The invention belongs to the technical field of optical illumination, and particularly relates to a man-machine coexisting KrCl excimer safety sterilizing lamp.
Background
The diagnosis and treatment of pneumonia infected by the novel coronavirus (trial fifth edition) published by the national health and wellness Committee indicates that the novel coronavirus is sensitive to ultraviolet rays and heat. At present, a low-pressure mercury lamp radiating 254nm is generally adopted as an ultraviolet sterilizing lamp in the UVC ultraviolet sterilizing technology. The 254nm radiation efficiency of low-pressure mercury lamps is highest in atomic radiation, and 254nm radiation is absorbed by deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) to cause DNA and RNA damage, so that viruses are killed effectively, but the damage to eyes and skin of people is caused, and the disinfection is carried out in an unmanned environment. At present, no good method is available for inactivating viruses in air in public places with large flow of people in time.
Recent researches find that the far ultraviolet light (222nm) emitted by a KrCl excimer lamp tube can effectively sterilize and disinfect without damaging human eyes and skins, and the main reason is that the far ultraviolet light is safer than ordinary 254nm radiation because the far ultraviolet light is shorter in spectrum wavelength, is easier to be absorbed by proteins and the like, and cannot penetrate through the stratum corneum and the human eyes. However, the spectrum emitted by the KrCl excimer lamp tube has two secondary peaks near the wavelengths of 236nm and 257nm besides the main wavelength with the peak wavelength of 222nm, and although the intensity is very low, the photochemical ultraviolet injury action coefficient of the corresponding skin and human eyes is large, and the influence on the eyes and the skin is still generated. The invention provides a man-machine coexisting KrCl excimer safety sterilizing lamp, which is characterized in that a 222nm band-pass filter is used for filtering a spectrum emitted by a KrCl excimer lamp tube, radiation in a range of 235-265 nm is filtered, the biological safety of the KrCl excimer lamp tube is improved, a guarantee is provided for long-time man-machine coexisting sterilizing application of the KrCl excimer lamp tube in public places with high human flow, such as schools, hospitals, railway stations, airports and the like, and the lamp has important significance for epidemic situation prevention and control during virus pandemic.
