The sun is by far the strongest source of ultraviolet radiation in our environment.
Solar emissions include visible light, heat and ultraviolet (UV) radiation.
Just as visible light consists of different colours that become apparent in a rainbow,
the UV radiation spectrum is divided into three regions called UVA, UVB and UVC.
UVC has been used in industry and healthy field for many years.
The wave length of UVC LED is defined as 200nm ~ 280nm usually.
Reference the IUVA( International Ultraviolet Association), "The ultraviolet spectrum ('sterilization' range) that
is very important for water and air disinfection is the range absorbed by DNA (RNA in some viruses). This sterilization range is about 200-300nm."
The scientist has proved the range from 280nm ~ 300nm can be used for Disinfection and sterilization.
Generally, 265nm is the most efficient length, it is the peak to be absorbed by DNA.
Please feel free to contact us if you have any interest in UVC sterilization.
