222nm LED chips can be used in various public places. In the past, ultraviolet disinfection needs to be used in an environment without people. Only traditional disinfection methods can be used in crowded places, and these disinfection methods not only consume manpower but also pollute the environment. 222nm led disinfection solves this problem and can be widely used in places with a lot of people in the future.

 

Applications

1. Disinfection

2. Sensor light

3. Fluorescent spectroscopy

4. Industrial gas and chemical monitoring

5. UV light communication

6. Efficient airborne pollution elimination

7. Spectral analysis instrument

 

Application of UVC LED in escalator disinfection

In daily life, escalators have become a common means of transportation in public places in modern cities. Escalator handrails are mostly made of rubber, which is highly absorbent and prone to bacteria. In addition, the germs on people's hands will be cross-infected through the handrails, which may be one of the potential threats to modern public health. At present, this kind of escalator is available in subways, shopping malls, and railway stations, and many people touch it every day. Especially after the epidemic, the hygiene of handrails has become the focus of many people's attention. Escalator handrails have 17 times more bacteria than ordinary toilet handles, according to one study.

It is understood that most of the escalators are currently cleaned manually, and the cleaners clean them at a fixed time. They usually use rags and mops to clean, but it is worth noting that this cleaning method can only clean the dust on the surface, and cannot kill surface bacteria. In addition, this cleaning method is only for a specific period of time, and cannot be cleaned in time.

Is there any way to disinfect escalators safely, conveniently and instantly?

It has been found that since 2020, many elevator manufacturers have introduced escalator sterilization solutions to efficiently disinfect and sterilize escalator handrails to reduce the risk of cross-infection. According to reports, the handrail sterilization solution using far uvc led technology has been used on escalators in various places. Including airports, mass transit systems, commercial buildings, shopping malls, department stores, medical institutions, stadiums, museums and government buildings, etc. For example, the Ted Stevens Anchorage International Airport in Alaska, USA and the James Armstrong Richardson International Airport in Winnipeg, Canada both adopt the escalator handrail sterilization solution of this technology.

The UVC LED solution uses a built-in 222 nm LED that is harmless to the human body to irradiate the surface of the handrail. After a period of irradiation, it can destroy the DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) molecular structure in the cells of pathogenic microorganisms such as bacteria and viruses, which can make them die or cannot reproduce, and play a role in sterilization and disinfection. This method can realize all-round sterilization and disinfection of the handrails of the escalator in real time, and is effective in eliminating Escherichia coli, Staphylococcus aureus, etc., and the sterilization effect is as high as 99%. It can also reduce the risk of cross-infection of bacteria and viruses in crowded places.
