Decoding cutting-edge technology! 222 nm UV safe disinfection helps usher in a vibrant post-pandemic era
After three years of pandemic response, public attention to environmental health has increased, and the new disinfection technology "222nm UV sterilization" has also attracted significant attention. The application of 222nm UV products has been widely recognized in important venues such as the China Pavilion at Expo Dubai, the 2022 Beijing Winter Olympics, and epidemic prevention cabin hospitals/isolation hotels.
Compared to traditional 253.7 nm UV disinfection technology, the greatest advantage of 222 nm UV disinfection is achieving "dynamic disinfection, human-machine coexistence, and real-time protection."
222nm UV Disinfection - The New Favorite in the Tech World
222 nm ultraviolet light is hailed as human-safe UV. Previously, the American Conference of Governmental Industrial Hygienists (ACGIH) released updated documents, revising its UV hazard function and exposure limits. It is understood that the exposure limits in the far-UV band have been significantly increased: the daily irradiance limit for 222 nm has been raised from the original 22 mJ/cm² to 160 mJ/cm² (for corneal exposure) and 478 mJ/cm² (for skin exposure).
This effectively expands the application of far-UVC products in air purification, surface disinfection, and water treatment, making UV sterilization safer.
Guangmingyuan SAFEGLO 222nm Far-UVC Series
As a professional manufacturer of UV products and provider of solutions, Guangmingyuan collaborates with universities and research institutions on joint R&D, organizes teams to tackle key technical challenges, and develops 222nm far-UVC disinfection lamps that allow safe human-machine coexistence. The currently launched SAFEGLO 222nm far-UVC series has gained strong market recognition in epidemic prevention and disinfection applications, providing robust health protection for office and living spaces.
Efficient Disinfection
The Guangmingyuan 222nm excimer lamp emits light under high-frequency, high-voltage current excitation. After filtering through a nanoscale high-precision optical interference film filter, it emits pure 222nm ultraviolet light that is harmless to the human body. It irradiates pathogenic microorganisms such as bacteria, destroying the DNA structure within their bodies, causing immediate death or loss of reproductive capability, thereby achieving disinfection and sterilization. It features no secondary costs and leaves no residues after disinfection, truly realizing efficient and safe sterilization.
High Safety
222 nm is highly absorbed by biological materials and has low transmittance through living organisms. The outermost stratum corneum of the skin blocks 222 nm radiation from reaching living cells beneath the skin. The tear film protecting the outer surface of the cornea can block 222 nm. Therefore, it is safe for the human body and will not cause sunburn, skin cancer, cataracts, or other diseases.
An increasing number of studies indicate that 222 nm wavelength is equally effective against many pathogens, and this light poses no threat to the human body. According to foreign media reports, Columbia University in the United States and Kobe University in Japan have separately demonstrated through research that UVC radiation with a wavelength of 222 nm can inactivate germs without causing adverse effects on the skin and eyes, allowing for disinfection while people are present.
Therefore, this "black technology" anti-epidemic device solves a difficult problem in the field of disinfection: how to achieve "real-time disinfection without evacuation".
Product Features
1. Infrared Sensor Disinfection Mode
Features two sensor-based disinfection modes: "Lights Off When People Present" and "Lights On When People Present," which can be preset at the factory according to actual needs.
2. Smart Reminder Function
