Sterilization characteristics of UVC LED and its application in household epidemic prevention

In the field of sterilization and disinfection, UVC LED uses high-energy ultraviolet rays to irradiate microorganisms and destroy the nucleic acid structure, thereby achieving the purpose of microbial inactivation. And it can inactivate almost all microorganisms including bacteria, viruses, fungi, and algae.

In addition to UVC LEDs, there is another product on the market that utilizes the principle of ultraviolet sterilization - ultraviolet mercury lamps. Perhaps everyone is more familiar with this product. The exposed lamp tubes emitting purple light that we see on the walls of restaurants or laboratory operating tables are ultraviolet mercury lamps. However, the ultraviolet mercury lamp is excited by mercury vapor being collided with high-energy electrons, mainly 254nm and 185nm ultraviolet rays. The main problem with this product is that it contains mercury, which is not only harmful to the human body, but also unfriendly to the ecological environment. With the entry into force of the Minamata Convention, mercury-containing sterilization products will also be phased out. In addition, in the process of exciting 185nm ultraviolet rays, it will also be accompanied by the generation of ozone. Although it can play a certain role in sterilization, it will also endanger human health. Therefore, people cannot be present when using the ultraviolet mercury lamp, and it needs to be ventilated for more than half an hour before entering the room after turning off the lamp.

Far UV LED does not have these problems. It is a semiconductor light source, and the process of irradiating ultraviolet rays does not produce any chemical pollution, which greatly improves the sterilization efficiency of UVC LED products. In addition, UVC LED has the advantages of small size, flexible design, and convenient installation. Its sterilization device is flexible in design and can be used in small spaces where traditional ultraviolet mercury lamps cannot be used. UVC LED can cover various sterilization methods such as surface sterilization, air sterilization, and water body sterilization, and can be applied in home scenes. And because it is environmentally friendly and non-toxic, it can sterilize food, clothing, baby pacifiers and other items with high safety requirements.

As a professional far uvc led manufacturer, we also provide uvc led with a wavelength of 222nm. It overcomes the problem that traditional ultraviolet sterilization is harmful to the human body. It not only has a good sterilization effect but is also harmless to the human body, and it can also complete the disinfecting task in the scene where there are people.
