Description

Ultraviolet tube and its air purifier

The present invention relates to the technical field of a lamp, and more particularly to an ultraviolet lamp, and further relates to an air cleaner comprising the ultraviolet lamp.

Ultraviolet sterilization technology uses a radiation source for sterilization. It can be used in articles that cannot be washed with detergent or water. It is widely used in industry or daily life because of its wide sterilization surface, convenient use, low side effects and relatively low price. .

The wavelength range of ultraviolet light falls between 10 nm and 400 nm. Different wavelengths exhibit different bactericidal properties. For example, ultraviolet light at a wavelength of 185 can interact with air to decompose oxygen (O ₂ ) in the air into oxygen atoms (O) and air. The oxygen is combined, and the produced product has strong oxidation to destroy the cell wall of the decomposing bacteria, thereby destroying the genetic material, so that the metabolism and reproduction of the bacteria cannot be carried out and die, and the effect of sterilization and removal of odor in the air is achieved. Ultraviolet light of wavelength 254 can directly act on the genetic material DNA of the organism within 1 second, so that a new covalent bond is formed between adjacent thymine or Cytosine bases to form a double complex. (dimer), this change in DNA structure causes the organism to fail to form proteins and loses the ability to divide and replicate, ultimately leading to death for sterilization purposes. 365 wavelength ultraviolet light has a strong catalytic degradation function after irradiation of titanium dioxide. It can degrade harmful substances in the air, bacteria and their released toxins through redox reaction, and finally dissipates in the air in the harmless form of water and carbon dioxide, so it is often used. In addition to formaldehyde, deodorization, anti-fouling, air purification.

However, in general, ultraviolet rays can only propagate in a straight line in the form of light, and the sterilization effect has a defect of dead angle. The product generated by the reaction of ultraviolet rays at a wavelength of 185 with air can make up for this disadvantage, and thus the ultraviolet lamp having a wavelength of 185 is used. It is used together with UV lamps of other wavelengths, but the use of multiple lamps at the same time requires more space for the lamps to be placed, which causes inconvenience in use.
