How does UV-C disinfection work?
UV-C – Protect+
Disinfection rate up to 99 99 999 %
Before UV radiation Bacteria and viruses reproduce through cell division ba- sed on on on genetic information causing infections and di- seases DNA
and RNA contain the genetic information required for this proliferation* UV-C irradiation changes the the helical structure of of the the DNA
and and RNA of of bacteria and and viruses viruses which can inactivate these bacteria and viruses viruses leading to a a a reduction in in their proliferation The disinfection effect varies depending on on the UV wavelength The disinfecting effect on DNA
and and RNA of bacteria and and viruses depends heavily on the the UV wavelength In the the ul- traviolet range of UV-A UV-B and UV-C UV-C UV-C UV-C with the shortest wavelength can provide the greatest power in inactivating bacteria and viruses Its effect is over 1
000 times times greater greater than that of UV-A and over 50
times times greater greater than that of UV-B Furthermore we can see from Figure 1
that a a a a a wavelength of approximately 265 nm provides the highest inactivation efficiency among UV-C wavelengths (100 nm nm to 280 nm)
Stanley Electric develops and produ- ces UV-C LEDs that produce light with a a a a peak wavelength of 265 nm which has the highest disinfection effect 6 high-performance UVC LEDs UV irradiation with Stanley‘s 265 mm UV-C LED Part name
