SETi and Seoul Viosys Violeds Technology Demonstrated to Kill 99% of Coronavirus (SARS-CoV-2) in Less Than a Second

ANSAN, South Korea–(BUSINESS WIRE)–#AirborneViruses—Sensor Electronic Technology, Inc. (SETi) and Seoul Viosys (KOSDAQ: 092190), the leading global providers of UV LED technology and subsidiaries of Seoul Semiconductor, announced that Violeds technology can quickly and effectively kill 99.437% of SARS-CoV-2 in just a second. The test was conducted through KR Biotech in December 2020, a research institute specialized in conducting sterilization testing of coronavirus based in South Korea.

This test result demonstrates Violeds technology could be an effective way to disinfect airborne viruses, water systems, areas where COVID-19 patients occurred, and even the patient�s room in hospitals.

After exposing SARS-CoV-2 to UV LED module with Violeds technology for 1, 3, and 5 seconds respectively, the research team observed its inactivation rate. As a testing result, Violeds inactivated 99.437% in a second.

Violeds, an advanced compound semiconductor technology, is a safer and economically advanced solution to replace conventional UV lamps. The lamps include mercury, which does not dissolve and accumulates in the human body when UV lamps are broken. Because of the short lifespan of around 5,000 hours, UV lamps require periodic replacement. However, UV LED technology has the advantages of cost and safety with a long life of up to 50,000 hours, which is more than 10 times the life of a mercury lamp.

In addition, the UV LED market is rapidly replacing the USD 70 million UV mercury lamp market due to technological advancements such as miniaturization of less than 1mm and improved efficiency. As UV LED technology has been adopted by new industries for bio-healthcare and virus disinfection, according to Yole Développement, a market research company, the global market for UV LEDs is expected to grow into USD 2,786 million in 2025.

Violeds, safe UV light
1.	It is light, thin and compact with a size of less than 1?, and it can completely block UV exposure with its optimal design.
2.	The safety device developed by SETi and Seoul Viosys, a UV light detection sensor, enables users to check normal operation and UV leakage.
3.	It is possible to completely control the daily exposure allowance, the international safety standard.
4.	As UV light does not include harmful chemicals, there is no fear of secondary or tertiary damage such as death due to humidifier disinfectant.

“COVID-19 pandemic and risk of virus variants continue and despite vaccination of influenza vaccine, flu deaths in the U.S. are average more than 10,000 per year. As hundreds of millions of people around the world are exposed to various diseases, prevention of virus infection is now essential. So due to the hazards of chemical methods, professionally designed UV LED disinfection systems may be a safer solution and the world standard in the future,” said an official at SETi.
