UVC LED

What is UV-C LED?

Ultraviolet radiation from the sun includes UVA, UVB, and UVC bands. Ultraviolet-C (UV-C) wavelength ranges from 100 nm to 280 nm and the shorter the wavelength the more dangerous it is. Wavelength below 200 nm is vacuum ultraviolet and can be absorbed by air, while wavelength ranges between 200 nm and 280 nm can pass through the atmosphere; however the ozone layer acts as a barrier so only a small amount of UV-C reach the earth’s surface.

UV can destroy the DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) molecular structure of microorganisms so that bacteria is destroyed or unable to reproduce, in order to achieve the purpose of sterilization and disinfection. UV-C is the shortest wavelength of the UV light and has the strongest destructive effect on DNA. It is extremely harmful to bacteria, viruses, microorganisms, molds, unicellular algae, and other microorganisms. Generally, the sterilization effect can be achieved within 1~2 seconds after UV-C (UV-C wavelength 200-280 nm) irradiation.

Effectively suppresses the transmission of the Covid-19 virus!

Our UVC LED technology is derived from the work of the 2014 Nobel Prize in Physics laureates, Professors Isamu Akasaki and Hiroshi Amano. It features high luminous efficiency, low heat generation, low power consumption, long lifespan, durability, mercury-free, ozone-free, and single-wavelength advantages. This technology directly disrupts the DNA and RNA structures of microorganisms, preventing the formation of essential proteins, thereby causing immediate death or loss of reproductive capability.


In May 2020, experiments conducted by Miyazaki University proved that UVC LEDs could effectively suppress the infectivity of the Covid-19 virus by over 99.9%. Further experiments in June 2021 demonstrated that UVC LEDs are equally effective against Covid-19 variants.

Nikkiso & NKFG have successfully developed the world’s smallest UVC LED air disinfection system using high-power UVC LED technology.

UVC LEDs offer an instant on/off, mercury-free disinfection solution. Their compact size allows for flexible application in various disinfection systems. By utilizing specific wavelengths and custom UVC LED modules, they can destroy the DNA structure of particular pathogens, achieving effective sterilization.

The Environmental Protection Administration has set regulations for indoor air quality, including a requirement that indoor air should not contain more than 1500 CFU/m3 of airborne bacteria. Our UVC disinfection equipment is suitable for a variety of settings, such as universities, healthcare facilities, social welfare organizations, government offices, rail transport, civil aviation terminals, metro stations, shopping malls, providing clean and sterile air in enclosed indoor environments.


Applications of UVC LED air treatment and sterilization:
• Enclosed spaces
• Circulating airflow
• Food processing
• Medical and biotech industries
• Advanced sterilization after HEPA and activated carbon filtration

UVC LED water sterilization treatment

    Industries: pure water treatment, industrial, medical, leisure, delicate, agriculture, marine, food, aquaculture fishery



PearlAqua series from AquiSense was launched in 2012 and is the world’s first UV-C LED product specifically designed for water disinfection. The system integrates the most advanced LEDs into AquiSense’s unique and sophisticated design without the use of chemicals or mercury lamps. LEDs also have the advantage of on/off switch, infinite circulation, remote start/off, and no-heat-transfer to the processing liquid.

AquiSense team has rich experiences in water treatment and can provide professional solutions for world-class UV-C LED commodity. There are two modes of UV-C water sterilization: “overflow” and “static.” The overflow water sterilization requires high-speed sterilization time, and has higher requirements in UV-C power and waterway design.
Water flow range:1 LPM – 150 LPM

Application of UVC LED water sterilization treatment:
• Water outlet application (e.g. faucet)
• Combined with RO/filtration equipment for terminal sterilization or biofilm inhibition
• Shower head
• Water tap
• Application of water entry point (e.g. water tower)

Each UVC LED module can be equipped with a single wavelength and assembled to provide multi-wavelength coverage. By homogenizing the LED light source and using treated surfaces, a uniform intensity distribution is achieved to effectively kill pathogens.

UVC LEDs with wavelengths between 265nm and 285nm are commonly used for sterilization, but other wavelengths can also be utilized. One of the advantages of UVC LEDs is the ability to select almost any wavelength, allowing for targeted pathogen reduction. In May 2020, a joint experiment conducted by Miyazaki University and Nikkiso studied the sterilization effects of deep ultraviolet (UVC) LEDs. In the experiment, UVC LED light was irradiated on a liquid containing the novel coronavirus for thirty seconds. After three days of incubation, it was confirmed that the virus’s infectivity was reduced by over 99.9%. Miyazaki University noted that this technology is expected to be applied in preventing infections in healthcare facilities.

UVC LEDs are small, robust, lightweight, and easy to install, making them an ideal choice for portable sterilization.

UV-C LED is widely used in many fields. In order to develop more innovative applications to meet the needs of the market and the public, more advanced and sophisticated equipment is needed to test and study the ultraviolet spectrum.

UV-C LED has the advantages of Digital Disinfection™ and AquiSense is able to provide researchers with a variety of advanced ultraviolet disinfection and sterilization laboratory equipment. For example, PearlLab Beam™ can provide researchers with reliable and lightweight UV research equipment. One of the products can be used to test all wavelengths in the full UV spectrum, and the other product focuses on 220 nm wavelength or the far UV region.

Since the research of UV-C is still in its initial stage, more study on the disinfection effects is needed in the future. Therefore, after confirming its safety, PearlLab Beam will help with the expansion of UV-C to the consumer market and to further change the method of disinfection globally.

In addition to PearlLab Beam, AquiSense also has PearlLab Micro, PearlLab ThinFilm, PearlLab Plasma, and other equipment to meet various research needs.

Taikkiso is the general agent of AquiSense in the Greater China region, and can provide UV-C LED equipment components to laboratories and OEMs under a B2B business model.
