Seoul Viosys and SETi’s Violeds technology proves 99.9% sterilization of COVID-19 in 30 Sec

The study also finds the coronavirus becomes even more sterile when placed closer to the photon with longer exposure time.

Seoul Viosys and Sensor Electronic Technology, Inc. (SETi), global innovators of UV LED products and technology, announced that that it has been successful in achieving 99.9 per cent sterilisation of coronavirus (COVID-19) in 30 seconds. Tests were conducted with the research group of Korea University, Korea’s top rank university, by using a compound semiconductor Violeds technology that is being mass-produced.

As COVID-19 spread throughout the world, SETi and Seoul Viosys, the fourth-largest global LED maker of Seoul Semiconductor’s affiliates, devoted resources to show how Violeds technology can directly sterilize the virus. The goal has always been to provide technology for a cleaner world, and this includes minimising the spread of COVID-19, while the company will quickly offer strong sterilization solutions for coronavirus in air as well as surface of goods such as facial masks and smartphones.

In the study by SETi and Seoul Viosys, Violeds technology is used to show just how strong the sterilization effect can be on COVID-19 when exposed to Violeds photons for 30 seconds. The study also finds the coronavirus becomes even more sterile when placed closer to the photon with longer exposure time. In addition to testing the coronavirus, the Violeds technology also proved to be successful in sterilizing 99.9 per cent of other harmful bacteria such as Escherichia coli, Staphylococcus Aureus, Pseudomonas Aeruginosa, Klebsiella Pneumonlae, and Salmonella Typhimurium.

Violeds, compound semiconductor technology, is the brand name of technology that utilises UV LED for sterilization and deodorisation functions. This concept clean technology has been developed by Seoul Viosys with SETi since 2005 to prevent germ proliferation through the use of a light source (photon) without the need of chemicals that could be harmful to humans. Violeds technology, which has been recognised for its excellent sterilization and stability, has also been used to clean environments for astronauts at NASA’s space station in the United States. Until now, general commercial applications have been limited, as their lifetime was too short for prolonged use. However, since 2019, new patented technology has extended the previous life span by 50,000 hours, making it now the optimal solution for air purification and water sterilization products.
