Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.V light is electromagnetic radiation with wavelengths shorter than visible light. UV can be separated into various ranges, with short-wavelength UV (UVC) considered germicidal UV. At certain wavelengths, UV is mutagenic to bacteria, viruses and other microorganisms.
Applications ranging from curing to disinfection and sterilization will benefit from new UV LEDs in the 265â300-nm band. Nikkiso America has announced the general availability of 50-mW deep-ultraviolet (UV) LEDs that the company said have operating lifetimes in excess of 10,000 hours. The evolution of UV-LED technology at shorter wavelengths holds great potential for applications ranging from industrial curing to water sterilization.
