Description

A multifunctional portable deep ultraviolet LED sterilizer

technical field

The utility model belongs to the technical field of deep ultraviolet disinfection, in particular to a multifunctional portable deep ultraviolet LED sterilizer.

Background technique

Ultraviolet light is sunlight with a wavelength of 10 to 400 nanometers (nm), which can penetrate the cell membrane and nucleus of organisms, destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, and cause growth. Cell death and/or regenerative cell death have the effect of killing various germs, such as bacterial propagules, spores, viruses, fungi, etc. In photobiology and physics, ultraviolet light is usually divided into long-wave UVA, medium-wave UVB and short-wave UVC by wavelength. Among them, the best sterilization effect is short-wave ultraviolet UVC with a wavelength of less than 280nm. However, it has been absorbed and scattered by the ozone layer in the atmosphere, so it cannot reach the ground and cannot be used by people.

People use artificial light sources to produce UV light. The traditional ultraviolet germicidal lamp is a kind of gas discharge lamp, which uses bipolar arc discharge to vaporize mercury and generate mercury vapor characteristic spectral lines. At present, most of the common ultraviolet germicidal lamps on the market use low-pressure mercury lamps to emit short-wave ultraviolet rays of 254nm for disinfection.
