Companies start mass production of Violeds UV-LED technology designed to sterilise 99.9 percent of the coronavirus in 3 seconds

Sensor Electronic Technology, Inc. (SETi) and Seoul Viosys, providers of UV LED technology and subsidiaries of Seoul Semiconductor, have started mass production of UV LED module designed to sterilise 99.9 percent of the coronavirus in 3 seconds using Violeds, a UV LED technology developed by Seoul.

Seoul Viosys is also developing a Photon Shower device that applies the UV LED technology to contribute to the safety of medical staff and patients who have been struggling amid COVID-19 pandemic.

The BIO research team at Seoul Viosys has conducted numerous research and development projects with in-house laboratories, cultivating and sterilising various bacteria and viruses. In April 2020, a Violeds sterilisation test conducted with a research group at Korea University demonstrated that Violeds sterilises coronavirus.

The Photon Shower device is a whole-body sterilisation solution that uses only light, (photons) to sterilise various germs on the surface of peoples' clothing in seconds when they enter the Photon Shower. This sterilisation function can also be added to conventional air shower devices, which are used for dust removal only.

The Photon Shower using Violeds technology is expected to contribute to minimising infections in hospitals in the future. According to the US CDC (Centers for Disease Control and Prevention) statistics, more than 14,000 people die annually from hospital infections in the US alone.

“There are countless industrial fields where the Violeds UV LED module, which sterilises 99.9 percent of viruses on the surface of everyday objects in just three seconds, can be applied,” said Mike Berens, director of sales for SETi. “It has been supplied to US escalator manufacturers to be applied to escalator handle sterilisation solutions, and we expect global customer demand to increase in the future.”

Violeds is a UV LED technology jointly developed by SETi and Seoul Viosys through more than 20 years of research and development. It uses only light to sterilise, and can be optimally designed depending on the application by considering the following five factors: wavelengths from 200nm to 400nm, distance to objects, light irradiation time, brightness of light (intensity), angle, and area of irradiation surface.

This technology has already been applied to the International Space Station of the National Aeronautics and Space Administration (NASA), and is also applied to various home appliances and automobiles, including air conditioners, air purifiers, water purifiers and dishwashers.

Applying this technology, Seoul Viosys is also producing an air purifier, the VAC Series which is optimally designed to filter and sterilise 99.9 percent of bacteria and virus particles in 30 seconds; and a multi-steriliser device, the VSM+ Series, which sterilises the surface of everyday objects, removing 99.9 percent of bacteria and virus particles in 10 minutes.
