Portable uv-c lighting handheld ultraviolet lamp led uv light for air purifier   

Product Description
 
Product features  
Double sterilization effect
  This product includes ultraviolet and ozone, which can avoid the defect of single sterilization.
      a The UV light can emit an ultraviolet ray with a wavelength of 253.7nm,which kills the bacterial viruses within a few seconds and the sterilization efficiency is up to 99%.
      b Ozone sterilization: Ozone's diffusion can make up the disadvantages that Uv can only be transmitted in a straight line and the sterilization has dead angles, it can reach anywhere in the air and make the sterilization more effective and thorough.
 
Sterilization and odor removal principles
(1)UV sterilization principle
     a Sterilization---UV
      UV is the generic term of 100-400nm wavelength radiation in the lectro magnetic spectrum, it is divided into UVA, UVB, UVC and UVD  (14 bands, but only UVC has sterilization effect, especially the 253.7nmUV ray, which has the strongest sterilization effect.
b. How UVC kills the bacterial viruses?
      By irradiating microorganisms like bacteria and viruses, UVC can destroy the molecular structure of DNA or RNA in microorganisms'cell and cause the break of DNA chain and cross between nucleic acids and proteins, which can cause the death of growth and Regenerative cells and achieve the sterilization effect.c, Ozone sterilization principle
     C  Ozone O3 has strong oxidization, it can destroy the cell wall of bacterium and oxidize and decompose high polymers like glucose oxidase, RNA, DNA, protein, lipid and saccharides, which can cause the death of bacterium and achieve the sterilization effect.
All UVC light has passed the CE and ROHS Certification.
