Four biological effects of mosquito killers

1. VA band: wavelength 320~400nm, also known as long-wave black spot effect ultraviolet. It has strong penetrating power and can penetrate most transparent glass and plastics. UVA with a wavelength of 60nm conforms to the phototaxis response curve of insects, and can be used to make insect trap lamps. UVA ultraviolet rays with wavelengths of 300-420nm can pass through special colored glass tubes that completely cut off visible light, and only emit near-ultraviolet light centered at 365nm, which can be used for ore identification, stage decoration, currency verification and other places.

2. 3UVB band: wavelength 275~320nm, also known as medium wave erythema effect ultraviolet rays. Medium penetrating power, its shorter wavelength part will be absorbed by transparent glass, UVB ultraviolet rays have erythema effect on the human body, can promote mineral metabolism and vitamin D formation in the body, but long-term or excessive exposure will make the skin tan, and Cause redness and peeling. The ultraviolet health care lamp and the plant growth lamp are made of special transparent violet glass (not transmitting light below 254nm) and fluorescent powder with a peak near 300nm.

3. UVC band: wavelength 100~275nm, also known as short-wave sterilization ultraviolet. Its penetrating ability is the weakest, unable to penetrate most of the transparent glass and plastic. The short-wave ultraviolet rays contained in the sunlight of outdoor mosquito killers are almost completely absorbed by the ozone layer. Short-wave ultraviolet rays are very harmful to the human body. Short-term exposure can burn the skin, and long-term or high-intensity exposure can also cause skin cancer. The ultraviolet germicidal lamp emits short-wave UVC ultraviolet rays.

4. UVD band: The wavelength is less than 100nm, also known as vacuum ultraviolet. The wavelength of the mosquito trap tube is 365nm, which is only attractive to mosquitoes and other insects, and does not cause any harm to the human body.
