On February 27, Hong Kong reported that the number of newly confirmed cases in a single day exceeded 20,000, reaching a new high. In an exclusive interview with the media, Feng Zijian, an expert who participated in guiding the mainland's aid to Hong Kong in the fight against the epidemic, and vice president and secretary-general of the Chinese Association of Preventive Medicine, emphasized that the current epidemic of new coronary pneumonia in Hong Kong is still accelerating, and various measures have been taken to try to suppress the upcoming epidemic. The peak has become the top priority of Hong Kong's anti-epidemic work.
According to the findings of "Expert Says UV", in order to better control the epidemic, the Hong Kong Food and Environmental Hygiene Department announced on the 23rd that it is following up the installation of ultraviolet UVC disinfection devices on escalator handrails in markets, cooked food markets and cooked food centers.
Suitable for places with dense and high mobility
Experts said that UV has also observed that due to the epidemic situation in the past two years, except for the installation of UVC devices on escalators in markets, "escalator infection incidents and policy requirements" all indicate the importance of escalator disinfection, which is different from the past. Manual cleaning can further improve the efficiency of disinfection and block the risk of transmission.
It is worth noting that according to the current layout of escalators in the market, UVC sterilization devices are not only used in markets and markets, but also in libraries, shopping malls, hotels, railway stations, airports, long-distance passenger stations, etc. Large places, such as five major domestic airports, are using UVC sterilization, as follows:
In 2020, Changchun Longjia International Airport will install ultraviolet sterilization devices on escalators and moving walks.
In June 2021, Hohhot Airport completed the disinfection device for escalator handrails, changing from regular disinfection to real-time disinfection.
In August 2021, Beijing Daxing Airport chose to be equipped with an ultraviolet sterilization device.
In September 2021, Guangzhou Baiyun International Airport introduced a self-generating handrail ultraviolet disinfection device in Terminal 1, using 265nm wavelength ultraviolet LED radiation for sterilization.
In December 2021, 50 escalators (including moving walks) in the main passenger flow of the terminal building of Xi'an Xianyang International Airport will be equipped with handrail ultraviolet sterilization devices.
Terminal manufacturers have joined the market competition
According to QYResearch data, the escalator market is expected to reach 35 billion yuan in 2026, with a compound annual growth rate (CAGR) of 3.7%. At present, many well-known elevator manufacturers have entered the market. For example, Toshiba Elevator released the TG series of escalators with UV LED sterilization function, with an estimated sales volume of 250 units per year. It is understood that in addition to the remote monitoring system to prevent the long skirt from being clamped, the elevator also adds a UV-LED sterilization device that is currently the most popular.
According to its introduction, UVC-LED can be used to illuminate the moving handrail when the escalator is running, and 99% of the moving handrail can be sterilized in about 30 minutes. Considering the safety of users, the sterilizer is installed inside the escalator, such as the folded part of the moving handrail.
Hitachi Elevator also installed UV irradiation equipment with a wavelength of 270~285nm in the escalator to sterilize the handrails and steps in real time, reducing the risk of cross-infection of bacteria and viruses in crowded areas.
These mid- and upstream companies have the opportunity
It is understood that there are currently two main ways to obtain UVC for sterilization and disinfection: traditional mercury lamps and ultraviolet LEDs. Compared with traditional mercury lamps, UVC-LEDs are gradually replacing mercury lamps with obvious advantages such as miniaturization, non-toxicity, long life and convenient use.
According to the "2021 UVC-LED Industry Research White Paper" jointly compiled by the industry research center and a number of enterprises, UVC-LED has a complete industrial chain, similar to the traditional LED industry chain, which can be mainly divided into chips, packages/molds Group, downstream terminal applications and other fields.
In terms of UVC-LED upstream chip manufacturing, there are mainly companies such as Guangli Technology, Sanan Optoelectronics, Yuanrong Jason, Zhongke Luan, Shenzi Technology, Huacan Optoelectronics, Zhixin Semiconductor, Anxinmei Semiconductor and so on.
In the midstream of UVC-LED, packaging and modules are also accelerating the layout, mainly including Seoul Viosys, GMKJ LED and other companies.
"Experts say UV" believes that in the long run, the regularization trend of the new crown epidemic will increase people's daily demand for virus killing, and UVC killing equipment will replace traditional sterilization methods in the future, which will promote the volume of UVC-LED killing equipment.
