Ultraviolet light generator

Abstract

The invention discloses an ultraviolet light generator, and belongs to the technical field of photoelectricity. The ultraviolet light generator comprises a body and a fixing support arranged at the upper end of the body. The body is a sealed cavity made up of silica glass pipes, a through hole is formed in the middle of the body, and the cavity is inflated with one or more of argon, krypton, xenon, neon and Kr85. The two ends of the body are symmetrically provided with magnet rings, and the top end of each magnet ring is provided with an induction coil which is connected with a high frequency generator through a connecting wire. The body is provided with an amalgam containing cavity communicated with the sealed cavity of the body. When the ultraviolet light generator works, the magnet rings induct the gas and mercury steam inside the cavity, the mercury steam releases ultraviolet lights, and the problem that the ultraviolet light generator is short in service life because wastage of emitting materials is solved. Due to the fact that sputtering of the emitting materials does not exist, the pollution problem inside the cavity is solved, and the retention rate of the energy of the spectrum emitted by the ultraviolet light is more greatly improved.

Description

technical field [0001] The invention relates to an ultraviolet generator and belongs to the field of photoelectric technology. Background technique [0002] Ultraviolet is the general term for radiation with wavelengths from 10nm to 400nm in the electromagnetic spectrum. According to wavelength, it can be divided into: near ultraviolet (UVA), far ultraviolet (UVB) and ultra-short ultraviolet (UVC). Ultraviolet rays can ionize oxygen in the air to generate oxygen free radicals and ozone, both of which have strong oxidizing effects and can be used for fast curing of glue in the chemical industry and printing industry. Far ultraviolet (UVB) with a wavelength of 253.7nm can break the replication ability of DNA to produce proteins. After the DNA and RNA of bacteria and viruses are damaged, their protein production ability and reproductive ability have been lost. Because bacteria and viruses generally have a short life cycle, they cannot reproduce bacteria, and the virus will die...

Problems solved by technology

[0003] At present, the commonly used ultraviolet generating device adopts electrode emission, which has problems such as large material loss, easy sputtering of consumables in the cavity, and large pollution; in addition, the working life of the current ultraviolet generator is not long, because the ultraviolet lamp is in the working process. In the process, the material itself will be exposed to ultraviolet radiation, and the material will age quickly and the product will be damaged; moreover, as the material of the ultraviolet generating device ages, its transmittance will also decrease, which will affect its performance, resulting in that the amount of ultraviolet rays in the later period cannot be achieved. fulfil requirements
