Urban transportation, such as subways, buses, high-speed rails, airplanes, etc., is the current mainstream mode of travel, and it is also the main mode that facilitates the transportation of large numbers of passengers. However, the hidden danger is that the environment in the carriage is relatively closed and the people are dense, which can easily lead to the mutual infection of bacteria and viruses, especially the occurrence of the new crown epidemic, and urban traffic was once forced to stop operating.
It is understood that the most effective solution has been proven to be uniformly worn masks by the people in the car and continuous and effective disinfection of the air in the car. There are many disinfection methods, mainly including disinfectants and ultraviolet rays. The UVC-LED, which is favored by all walks of life, can quickly and efficiently kill almost all bacteria and viruses, and is harmless to the human body. It can also accurately control the sterilization process to achieve Continuous and effective disinfection.
"GMKJ LED Wind Direction" observed that the current four major traffic has covered UVC-LED sterilization, sorted out as follows:
1. Zhongke Lu'an: Working with CRRC to apply deep ultraviolet sterilization to rail transit
In 2020, Zhongke Lu'an and CRRC Group signed a strategic cooperation agreement, completed the installation and commissioning of samples, and installed UVC-LED sterilization devices on the subway. It is the first domestic enterprise to apply deep ultraviolet sterilization to rail transit scenes.
It is understood that the UVC-LED sterilization device supplied to CRRC this time, the overall supporting solutions from UVC-LED chip, package to module are provided by Zhongke Lu'an, using the deepest 260-265nm wavelength with the highest sterilization rate. UV LED solution. In the rail transit air ultraviolet disinfection system, the sterilization device loaded with the UVC LED module is installed in the air circulation air duct on the top of the rail transit car. When the air inside the car circulates into the air duct, the sterilization device starts to work in just a few minutes More than 90% of the bacteria and viruses in the air can be killed inside, and then fresh air can be blown into the compartment. This circulation mode can achieve a complete and instant disinfection of the compartment, which greatly reduces the risk of mutual infection among passengers.
2. Japanese machine installation: installation of sterilization and deodorization system "AEROPURE TECHNOLOGY™" on high-speed rail
Nikkiso announced that it will install AEROPURE TECHNOLOGY ™ on railway vehicles to assist in disinfection and deodorization of the interior space. It is understood that Aeropure is equipped with a unique sterilization and deodorization system "AEROPURE TECHNOLOGY™", which uses a combination of UV LED SumiRay and photocatalyst. The bacteria and viruses in the air are captured by a filter with a built-in photocatalyst, and they are irradiated with deep ultraviolet rays to inhibit bacteria and viruses. Growth.
3. Safran Cabin Company: install UVC-LED in the cabin bathroom
In order to reduce bacterial infections in aircraft cabins, Safran Cabin has developed a complete set of UVC-LED systems to ensure the safety of passengers, flight crews, cleaners and maintenance personnel.
Safran Cabin has developed automatic, redundant sensing technology to detect whether there are users in the bathroom and whether the bathroom door is closed. If the monitoring result is that there is no one in the bathroom and the door is closed, the UVC-LED can start to work to eliminate pathogens left on the surface after the passenger touches it.
4. Guangpu shares: "intelligent control vehicle disinfection system" has been installed on public buses in two cities
In terms of the public transportation epidemic prevention system, the "Intelligent Control Vehicle Disinfection System" of Guangpu Co., Ltd. adopts three innovative technologies of ultraviolet UVC+UVA+photocatalyst, which integrates disinfection and sterilization, which can quickly kill bacteria and viruses in the air in the car, and purify the interior of the car. Peculiar smell, and will not cause corrosion and damage to the equipment in the car. The staff can also use the Guangpu disinfection management system to dynamically monitor the actual operation of the disinfection equipment in real time, reduce the frequency of going to the equipment site, greatly improve the efficiency of operation and maintenance, and make active operation and maintenance more evidence-based.
At present, Guangpu's new "Intelligent Control Vehicle Disinfection System" has passed the stability test, and the product has obtained authoritative technical safety certification and conforms to national mandatory standards. Anxing series of public transportation disinfection and epidemic prevention systems have been installed on buses in Pizhou City and Xiamen City, Jiangsu Province. Install and use.
GMKJ LED is deeply engaged in healthy and smart light sources, providing the market with a full range of ultraviolet UVA UVB UVC LED, infrared IR LED VCSEL products and program services. It has hundreds of high-quality partners in the domestic and foreign markets to jointly promote the use of light technology to create a healthy and smart life. .
