Seoul Viosys mass producing Violeds module to sterilize Coronavirus
Ultraviolet LED product maker Seoul Viosys Co Ltd (a subsidiary of South Korean LED maker Seoul Semiconductor Co Ltd) says that, using its Violeds UV LED technology, it has developed an optimal module designed to sterilize 99.9% of the coronavirus in 3 seconds, and has begun mass production. Also, using this technology, Seoul Viosys is developing a ‘Photon Shower’ product that can contribute to the safety of medical staff and patients who have been struggling amid the COVID-19 pandemic.
The BIO research team at Seoul Viosys has been conducting numerous R&D projects with in-house laboratories cultivating and sterilizing various bacteria and viruses. In April, a Violeds sterilization test conducted with a research group at Korea University proved that Violeds does sterilize coronavirus. By applying this technology, Seoul Viosys is producing the VAC air purifier, which is optimally designed to sterilize filters by 99.9% in 30 seconds, and the VSM+ multi-sterilizer, which sterilizes the surface of everyday objects by 99.9% in 10 minutes.
The new Photon Shower is a whole-body sterilization solution that uses only light to sterilize various germs on the surface of people’s clothes in seconds when they enter it. This sterilization function can also be applied to a conventional air shower that is used for dust removal only.
Infections in hospital are also serious. According to the US CDC (Centers for Disease Control and Prevention) statistics, 14,000 people die annually from hospital infections in the USA alone. Using Violeds technology, Photon Shower can contribute to minimizing infections in hospitals in the future, says Seoul Viosys.
“There are countless industrial fields where the Violeds module, which sterilizes 99.9% of viruses on the surface of everyday objects in just three seconds, can be applied,” notes Seoul Viosys. “It has been supplied to US escalator manufacturers to be applied to escalator handle sterilization solutions, and we expect global customer demand to increase in the future.”
Violeds is a UV LED technology that uses only light to sterilize, and is optimally designed depending on application area 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. The technology has already been applied to the International Space Station (ISS) 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.
