In order to further acknowledge whether short-wave UV LED lamp beads can really penetrate the skin and eyes, causing diseases such as cancer and cataracts. Brenne's team, a physicist at Columbia University Medical Center in New York, tested far- and short-wave ultraviolet light that penetrates the surface of the eye or skin. The study found that the ultraviolet light of sterilized LED lamp beads with shorter wavelengths may not be harmful to the human body, and according to the theory, it was developed into a new tool, which can be used in campuses, crowded planes, food processing plants, and even operating rooms and experiments. room and other places to slow down the spread of disease.

In addition, to recognize whether short-wave LED lamp beads UV light can deal with the number one health problem that exists in many public places: planktonic bacteria. The next step of testing was carried out; first, the team nebulized the influenza virus in the test chamber, then irradiated the virus with short UV light with a wavelength of 222NM, and as a control, some were not exposed to the short UV light. Afterwards, the researchers collected liquid samples from the test chamber and spread them in the kidney cells of dogs susceptible to influenza infection. The results showed that the samples that had not been irradiated with short UV light could infect the cells, while those irradiated with short UV light could infect the cells. Samples cannot.
