UV lighting for disinfection -eVIO-

eVIO is a completely new type of ultraviolet light that can be used in occupied environments, which has not been possible with conventional ultraviolet wavelengths. eVIO uses advanced technology to suppress the effects of ultraviolet rays on the bodies of humans and animals, while maintaining the virus suppression and sterilization capabilities inherent in ultraviolet rays.

 

 

What eVIO can do

 

It can sanitize space and object surfaces with ultraviolet light even in an occupied environment.

Space disinfection

eVIO is highly effective for space disinfection.

In particular, when operated in a manned environment, eVIO can sterilize an entire space without affecting the human body by emitting ultraviolet rays that have been stripped of their harmful wavelengths, thereby maintaining a safe and clean environment.

Surface disinfection

eVIO is also effective in sterilizing object surfaces.Continuous irradiation is possible, especially in an unattended environment, which maximizes the sterilization effect.

eVIO safety

 

　It has been confirmed that it is safe to use in a manned environment.

222nm UVUltraviolet light has a wavelength of 10-400 nm and is shorter than visible light and has a strong bactericidal effect.

The wavelength of 222 nm is extremely useful because it retains the bactericidal effect without affecting the human body.

 

Low impact on the human body

The absorption coefficient of proteins and keratin differs between the 222 nm UV and the conventional UV wavelength.

Since 222nm ultraviolet light does not penetrate into the skin and eyes, it has been found to have lower impact on the human body.

On May 12, 2021, IUVA (International Union of Ultraviolet Association) issued a white paper regarding 222nm (Far UV-C).

“There is no evidence that 222nm (Far UV-C) has any adverse effects on the human body (eyes or skin), including consideration of skin cancer.

“Inactivation of viral pathogens by Far UV-C is more effective than by conventional UV-C.

eVIO Advanced Technology

 
Removing harmful wavelengths from UV light requires superior coating technology. 

eVIO does not use external filters, which are common in conventional products. 

eVIO is the world’s first technology that can emit exclusively the 222nm UV wavelength.

 
Integrated harmful UV light-blocking coating

eVIO has a harmful ultraviolet blocking coat inside the lamp, and emits exclusively the wavelength of 222 nm with the harmful ultraviolet rays removed by the UV lamp.The lamp-integrated coat dramatically improves durability and maintainability compared to conventional products.

High efficiency internal reflective coating

eVIO has a special reflective coating on the inside of the lamp that allows light rays to be reflected inside the light and efficiently extract the 222 nm wavelength.Sensor technology

Although the safety of 222nm UV light is scientifically supported, the United States ACGIH (American Conference of Governmental Industrial Hygienists) has established a Threshold Limit Value (TLV).

Therefore, the eVIO uses motion sensors to control the operation so that the this limit is not exceeded in a manned environment.
