Characteristics of UV led strip disinfection
Bactericidal effect of Ultraviolet led strip is stronger, but the object of penetration is weak. It applies to the operating room, burn unit, space disinfection of infectious diseases between rooms and sterile and non-heat-resistant materials and countertop surface disinfection.
ultraviolet absorption and coincidence photochemical sensitivity range have crossed between UV led strip disinfection’ band with DNA of microbial nucleus.The absorption spectrum of DNA was 240~280nm and the absorption peak was 260nm.It is commonly considered that UV led strip can change and destroy the structural , change the genetic transcription of the cells, and make the organism lose protein synthesis and reproduction ability, other protein absorption (phenylalanine, tryptophan and tyrosine in the absorption peak of 280nm) may also play a role in UV disinfection process.InGeneral , The wavelength of sunlight ultraviolet radiation reaching the surface of the ground is 287~390nm, and the wavelength of ultraviolet radiation is about 250~285nm.
the absorb function of atmospheric ozone layer which can reduce the intensity rate of 290nm UV, so the sterilization ability of the sunlight is less than that of the 290nm uv led.
