Far UVC Technology 150w 222 nm UVC Light

222 nm uvc light has been proved to be harmless to the human body, therefore, it can be used more widely. And the far uvc technology has also begun to be gradually used in different ultraviolet disinfection products.With its non-polluting, harmless to human body and high efficacy advantages, it will have great potential in the market.

We all know that the widespread use of traditional UVC light sources in public places is limited, because traditional UVC light sources can damage our skin and eyes.However, the emergence of 222nm ultraviolet light will completely overturn this matter. Studies have proved that ultraviolet rays with a wavelength of 222nm will not cause harm to the human body.And at present, uvc 222 nm lamps are used in a wide range of applications.

 

Applications

1. Disinfection for household electrical appliances

2. Food and clothing object surface sterilization

3. Sterilization and disinfection of water，air

4. Sterilization of medical device

5. Disinfection of public places

 

222 nm uvc light can effectively inactivate the aerosolized virus in the air

UV-LED ultraviolet disinfection lamps generally refer to LEDs with a central wavelength of light emission below 400nm, but sometimes when the light emission wavelength is greater than 380nm, it is called a near-ultraviolet LED, and when it is less than 300nm, it is called a far-ultraviolet LED. Due to the high bactericidal effect of short-wavelength light, ultraviolet LEDs are often used in biomedicine, anti-counterfeiting identification, purification (water, air, etc.), computer data storage, and military affairs.Ultraviolet antivirus is not new, but it should be noted that long-wave ultraviolet (UVA, UVB) can cause damage to human eyes and cause skin cancer because of its strong penetrating power.

Airborne microbial diseases, such as influenza and tuberculosis, represent a major public health challenge. A direct way to prevent airborne transmission of viruses is to inactivate airborne pathogens, and the antimicrobial potential of UVC ultraviolet light in air has long been established. However, because traditional UVC light sources are both carcinogenic and cataract-causing, the widespread use of far uvc technology in public places is limited. At present, relevant research has proved that far ultraviolet rays (207-222 nanometers) can effectively inactivate bacteria and will not cause damage to mammalian skin exposed to uv rays. This is because bacteria and viruses are microns or smaller in size , far ultraviolet rays can penetrate and inactivate them. And because of its strong adsorption in biological materials, far ultraviolet rays cannot penetrate the outer layer of human skin or eyes (non-biological).

222 nm uvc light can effectively inactivate the aerosolized virus in the air, and the required dose is very low,only 222nm light of 2mj/cm² can inactivate 95% of the aerosolized H1N1 influenza virus. Maintaining sustained low dose rates of far-ultraviolet radiation in indoor public places is a promising and safe way to reduce the spread of airborne microbial diseases.
