摘　　要：由于清洁环保、不产生消毒副产物等优势,紫外线(Ultraviolet,UV)作为消毒技术已得到广泛应用。作为新兴的UV光源,输出波长在200~300 nm范围内的杀菌紫外线发光二极管(Germicidal Ultraviolet-Light Emitting Diodes,GUV-LED)具有输出波长范围广、环境效益高等优势,在消毒领域获得越来越多的关注。本文针对GUV-LED光源、消毒机制和效果方面的研究进展进行了综述:与低压汞灯相比,目前GUV-LED的光电转化效率仍十分有限(<5%);核酸损伤(255~265 nm)和蛋白质损伤(280 nm附近)为GUV-LED的主要灭活机制;不同微生物对GUV-LED的抗性大致为病毒>孢子>细菌;细菌和病毒更易受核酸损伤被265 nm和260 nm附近的GUV-LED灭活,孢子在265 nm和280 nm附近的灭活效果相近。本文旨在为LED技术在消毒领域的研究和应用提供参考。Ultraviolet(UV)light has been widely applied as a disinfection technology due to its advantages such as cleanliness,environmental friendliness and absence of disinfection by-products.As an emerging UV light source,germicidal UV light-emitting diodes(GUV-LED)with output wavelengths in the range of 200~300 nm offer advantages such as a wide output wavelength range and high environmental benefits.They are gaining increasing attention in the field of disinfection.This paper provides a comprehensive review of the research progress on GUV-LED light sources,disinfection mechanisms,and effectiveness:compared to low-pressure mercury lamps,the photoelectric conversion efficiency of current GUV-LED remains very limited(<5%);nucleic acid damage(255~265 nm)and protein damage(near 280 nm)are the main inactivation mechanisms of GUV-LED;Different microorganisms exhibit varying resistance to GUV-LED,generally with viruses>spores>bacteria;bacteria and viruses are more susceptible to nucleic acid damage and are inactivated by GUV-LEDs near 265 and 260 nm,while spores show similar inactivation effects near 265 nm and 280 nm.This article aims to provide a reference for the research and application of LED technology in the field of disinfection.
