What is the wavelength of the violet light of the mosquito killer lamp?
Zheng Yiping, a mosquito expert from the Nanjing Center for Disease Control and Prevention, has done relevant research. He said: "Ultraviolet lamps have the sterilization effect of producing ozone and inactivating the surface of objects in a short period of time, but the sterilization effect of this ultraviolet lamp is similar to that of killing. Dead mosquitoes don't matter."
The ultraviolet light traps mosquitoes, and when the mosquitoes touch the outer high-voltage power grid, they are instantly electrocuted and killed. When people use UV mosquito killer lamps, they can often hear a popping sound, which is the sound of killing mosquitoes due to the instantaneous high pressure. "
Ultraviolet lamps also have certain health risks, because the human body cannot receive a large amount of ultraviolet radiation.
At present, the wavelength of the general ultraviolet mosquito killing lamp is 365nm, which belongs to the longer wavelength UVA band. The ultraviolet ray in this band has a strong penetrating ability and can penetrate most transparent glass and plastics. UVA can also reach the dermis layer of the skin, destroy elastic fibers and collagen fibers, and tan the skin. However, experts say that as long as it is not exposed for a long time, there is no need to worry.
