The rearch about 222nm UVC Led chip 222nm UVC Led strips 

According to reports, studies have found that deep ultraviolet radiation with a wavelength of 222nm is harmless to human skin and eyes.

The deep ultraviolet wavelength of 200-280nm has a bactericidal effect, and has been widely used for sterilization. However, UVC radiation is harmful to human skin due to its penetrating power. However, studies have found that in terms of the ability to eliminate bacteria on the skin, the bactericidal effects of deep ultraviolet light with wavelengths of 222nm and 254nm are equivalent, and UVC radiation at 222nm will not cause skin cancer.

This is the first time in the world that the direct and repeated irradiation of 222nm deep ultraviolet light with strong bactericidal effect will not cause skin cancer, which shows that deep ultraviolet light with a wavelength of 222nm is safe for human eyes and skin. In view of this, this technology is expected to be widely used in sterilization and disinfection in places such as medical institutions and daily life.

The research team placed the mice under different ultraviolet radiation. One group is placed under a 222nm germicidal lamp, and the other groups are placed under a UVB light source of 280-315nm. It was found that the mice irradiated with UVB light source suffered from skin cancer and showed adverse reactions, while the mice irradiated with 222nm germicidal lamp did not suffer from skin cancer. In addition, the study observed its effect on the eyes of mice, and no abnormalities were found even under the microscope.

Therefore, the research team came to a conclusion that since deep ultraviolet light with a wavelength of 222nm can only reach the outermost layer of the skin-the stratum corneum, it will not damage the DNA of skin cells and ultimately has no adverse effects.

Studies have shown that deep ultraviolet radiation with a wavelength of 222nm has a strong disinfection ability and is harmless to human skin. Therefore, this technology is expected to be widely used in the field of sterilization.
