Sensor Electronic Technology, Inc. (SETi) and Seoul Viosys, the leading global providers of UV LED technology and subsidiaries of Seoul Semiconductor, announced that its Violeds technology can quickly and effectively kill 99.437% of SARS-CoV-2 in less than one second. The testing was conducted in December 2020 through KR Biotech, a South Korea-based research institute specializing in sterilization testing of the new coronavirus.

This test results demonstrate that Violeds UV LED technology could be an effective method to disinfect airborne viruses, water systems, as well as areas where COVID-19 patients were housed, including hospital rooms.

After exposing SARS-CoV-2 to the Violeds UV LED module for 1, 3, and 5 seconds respectively, the research team observed the inactivation rate of virus particles at 99.437% in one second.

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

UV LED technology is rapidly replacing the $70 million USD UV mercury lamp market due to technology advancements including miniaturization to less than 1mm2 as well as improved efficiency. As UV LED technology is adopted by new industries for bio-healthcare and virus disinfection, the global market for UV LEDs is expected to grow to $2.786 billion in 2025, according to Yole Développement, a leading market compound semiconductor research company.    

Violeds UV LED technology produces safe UV light

  • The UV LED module is light, thin, and compact with a size of less than 1mm2, and with optimal design it can completely block external UV exposure.
  • A UV light detection sensor, developed by Seoul Viosys as a safety device, enables users to check normal operation and prevent UV leakage.
  • It is possible to completely control the daily exposure of UV light to meet international safety standards.
  • Because UV light does not include harmful chemicals, there is no fear of secondary or tertiary damage from toxic materials used in the disinfection process.

“The COVID-19 pandemic and the accompanying risk of virus variants continue. Despite vaccination with influenza vaccines, flu deaths in the U.S. average more than 10,000 per year. As hundreds of millions of people around the world are exposed to various infectious diseases, prevention through disinfection is now an essential method for reducing infections. Due to the hazards of chemical disinfection methods, professionally designed UV LED disinfection systems represent a safer solution and may be the world standard in the future,” said an official at Seoul Viosys.

SETi currently has two sample disinfection products demonstrating UV-C LED technology available for purchase at VioledsStore.com
