(1)It kills the bacteria by bacteria oxidation instead of damaging normal cells
(2)No risks to humans , you can use them normally without taking any specific protective measures
(3)No light damage to most organic compounds which can be used normally for a long time
I Introduction Virus infectious virus diseases mostly break out at the turn of seasons , such as Respiratory infectious disease , the flu , Hand-foot-mouth disease by Enterovirus , ect .All kinds of viruses always hind in somewhere we can not recognize How to preventand eliminate the ubiquitous bacteria and viruses in our life ? The UV in sunlight isvery effective at sterilization and disinfection , but how to sterilize the place that sunlight does not illuminate ?
UV-A LED is a new trend which can achieve excellent effects M ( Alt + Altion . In thepast , we could only think of UV-C when we mentioned the use of LED sterilization But now , welcome to our new partner-uv-a . Are you so surprised the sterilization ofUV-A ? Now , lets explore its amazing sterilization effects !
II . The Comparison of Principles of Sterilization Between UV-C and UV-A First , UV-C can kill bacteria because the band of light is 200-280nm which is invisibleto human eyes , also called " invisible light sterilization . " However , another specific bandin UV-A which is around 405nm because it is visible to the human eyes , also is knownas " visible light sterilization.
III.The Effects Test of UV-A Sterilization
(I)The Bactericidal Rate of Different Irradiation Time
(II) The Human Injury Detection of UV-A
The detection result of UV-A in IEC62471 is an exemption , which proves that theharm of UV-A to human is negligible . So , it can be used as a light source of sterilization cautiously when people in the room , due to the harmless propertry of UV-A to human body . UV-A can be used as a sterilizing light source for many consumer electronics andhome appliances because it does not degrade most organic compounds
( III ) Advantages and Disadvantages Between UV-C and UV-A.
