The 222nm germicidal lamp is a lamp that uses ultraviolet light of 222nm wavelength for sterilization and disinfection. Compared with traditional 254nm UV lamps, 222nm germicidal lamps have the following characteristics:

1. Higher safety: 222nm ultraviolet rays are less harmful to the skin and eyes and can be used in environments where people exist without causing harm to the human body.

2. Efficient sterilization: 222nm ultraviolet rays have a high killing rate against bacteria, viruses and other microorganisms, and can effectively disinfect the air and surfaces.

3. No odor: Compared with 254nm ultraviolet rays, 222nm ultraviolet rays produce less ozone, and there is no obvious odor during use.

In terms of development prospects, 222nm germicidal lamps have received more and more attention and applications due to their high safety and efficient sterilization. Especially in the fields of medical and health, food processing, public places and other fields, the demand for air and surface disinfection is increasing, so 222nm germicidal lamps have broad market prospects. However, it should be noted that this technology is still in the development stage and its safety and effectiveness need to be further improved and verified to ensure its reliability in practical applications.
