The ultraviolet light of LED lamp beads completes sterilization by damaging the molecular bonds that bind bacterial genetic material to proteins. During this period, the most commonly used 254NM wavelength of light, which contains shorter LED beads with ultraviolet wavelengths, can penetrate the skin and eyes, leading to diseases such as cancer and cataracts.
To further acknowledge whether shortwave ultraviolet LED beads can truly penetrate the skin and eyes, leading to diseases such as cancer and cataracts. The team of physicist Brenne from Columbia University Medical Center in New York tested the penetration of far and short wavelength ultraviolet light through the surface of the eyes or skin. The study found that ultraviolet light from sterilized LED beads with shorter wavelengths may not cause harm to the human body. Based on theory, it has been developed into a new tool that can be used in campuses, crowded airplanes, food processing factories, and even operating rooms and laboratories, thereby slowing down the spread of diseases.
In addition, to acknowledge whether shortwave LED bead ultraviolet radiation can address the primary health issue that exists in many public places: planktonic bacteria. Conducted the next test; Firstly, the team atomized the influenza virus in the test box, and then illuminated the virus with a wavelength of 222NM of short ultraviolet light. As a control, some were not exposed to short ultraviolet light. Afterwards, the researchers collected liquid samples from the test box and dispersed them in dog kidney cells susceptible to influenza infection. The results showed that samples not illuminated by short ultraviolet light could infect cells, while samples illuminated by short ultraviolet light could not.
