Breathing clean air is essential to human survival, health and quality of life. Clean air is an important factor in creating a comfortable living environment. In fresh air, we can carry out various activities more comfortably, such as sports, leisure, sleep, work, etc. Air pollution will produce odor, affect the comfort of living and working environment, and make people feel uncomfortable and irritable. In order to allow people to breathe cleaner air indoors and ensure a comfortable and cozy living space, UVLEDTEK has developed high optical power, high reliability, long life, environmental friendly and energy-saving UVC series LED chips, SMDs, modules and other products specifically for air disinfection needs.

Working Principle of UVC LED Air Disinfection

UVC LED air disinfection uses ultraviolet rays (UVC) of a specific wavelength to kill and destroy harmful substances such as microorganisms in the air.

Destroy the DNA and RNA of microorganisms: The wavelength of ultraviolet rays emitted by UVC LED is usually between 200 and 280nm. Ultraviolet rays in this band can directly act on the genetic materials DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) of microorganisms (such as bacteria, viruses, fungi, etc.). When UVC irradiates microorganisms, it will cause chemical bonds in DNA and RNA molecules to break or form structural changes such as pyrimidine dimers, thereby interfering with the transmission and replication of genetic information of microorganisms. Microorganisms cannot metabolize, grow and reproduce normally, and eventually lose their activity, achieving the purpose of disinfection.

Producing photochemical reactions: When UVC irradiates the air, it also triggers a series of photochemical reactions. For example, UVC can make oxygen molecules (O?) in the air absorb photon energy and excite to form ozone (O?). Ozone has strong oxidizing properties and can react with a variety of biological molecules in microbial cells, further destroying the cell structure and function of microorganisms and enhancing the air purification and disinfection effect. In addition, UVC may also cause water molecules in the air to undergo photolysis, producing active substances such as hydroxyl radicals (?OH) with bactericidal effects. These active substances can also react chemically with microorganisms to destroy their cell components and achieve the effect of disinfection and sterilization.

Destroying the protein structure of microorganisms: In addition to acting on genetic material, UVC can also directly act on the proteins of microorganisms. Protein is an important substance that performs various physiological functions in microbial cells. The energy of UVC can break the peptide chains of protein molecules and change the spatial structure, resulting in protein denaturation and inactivation.

Harmful Substances in the Air That Can Be Killed by UVC

UVC disinfection kills a variety of harmful substances in the air by destroying the DNA or RNA of microorganisms, as follows:

Bacteria: It can effectively kill common bacteria such as Escherichia coli, Staphylococcus aureus, and Candida albicans. These bacteria may attach to dust particles or droplets in the air. UVC irradiation can destroy their cell structure and genetic material, prevent their growth and reproduction, and thus achieve the purpose of disinfection and sterilization.

Virus: It has an inactivation effect on many viruses such as influenza virus, coronavirus, and adenovirus. UVC can change the nucleic acid structure of the virus, making it lose its ability to infect and replicate.

Fungi: Fungi such as Aspergillus, Penicillium, and Mucor and their spores can also be killed by UVC. Fungal spores in the air are prone to allergic reactions and respiratory infections. UVC disinfection helps reduce the number of fungi in the air and reduce related health risks.

Warm reminder: When using UVC disinfection equipment, you should follow the correct methods and specifications to ensure purification effect and safety.

Advantages of UVCLEDTEK UVC LED in Air Sterilization

As a new type of air purification method, UVC LED air disinfection technology has the following advantages:

High-efficiency sterilization and disinfection: The sterilization effect is significant, and the sterilization rate can reach 99.99%, which can quickly and effectively kill a variety of harmful microorganisms in the air.

Safe and environmentally friendly: Compared with traditional chemical disinfection methods, no chemical agents are used, which avoids the harm of chemical residues and irritating odors to the human body and pollution to the environment. Moreover, UVC LED does not produce any harmful substances when it is not working, so it is safer to use.

Long life and high stability: UVC LED has a long service life, which can generally reach tens of thousands of hours. At the same time, its performance is stable. Under normal conditions of use, it can maintain a relatively consistent ultraviolet output intensity to ensure the stability of the disinfection effect.

Small size and easy installation: UV LEDs are relatively small in size, which is easy to install in various air purification equipment or ventilation systems. They can also be designed as portable disinfection equipment, suitable for different places, such as homes, offices, hospitals, schools, etc., which is flexible and convenient.

Fast response speed: It can generate ultraviolet rays for disinfection immediately after being turned on. It does not require preheating time like traditional ultraviolet lamps. It can also stop working immediately after being turned off. It is very convenient to use and can be used for disinfection at any time as needed.
