UVC: The wavelength is between 100-280nm, but because the wavelength below 200nm is vacuum ultraviolet, it can be absorbed by the air, so the wavelength of UVC that can penetrate the atmosphere is between 200-280nm. The shorter the wavelength, the more dangerous it is. Can be blocked by the ozone layer, and only a small amount will reach the surface of the earth.
2.What is the mechanism of UV sterilization?
UV can destroy the DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) molecular structure of microorganisms, so that bacteria can die or cannot reproduce, so as to achieve the purpose of sterilization.
3.Where can UVC LED be used?
According to different application scenarios, we may be able to see UVC LEDs in these applications in the future:
Surface sterilization: high-frequency public contact surfaces such as medical appliances, maternal and child products, smart toilets, refrigerators, tableware cabinets, fresh-keeping boxes, smart trash cans, thermos cups, escalator handrails and automatic ticket machine buttons, etc.;
Still water sterilization: water tank, humidifier, ice maker;
Flowing water sterilization: Flowing water sterilization module, direct water dispenser;
Air sterilization: air purifier, air conditioner.
The wavelength range of UVC LED is generally around 260nm, 275nm and 280nm.
