Vertically-integrated LED maker Lextar Electronics has developed UV(ultraviolet)-C LED disinfection solutions and has obtained third-party certification that its disinfection effects exceed 99.9%, according to the company.

Such solutions are based on UV-C LEDs that emit wavelengths of 255-285nm and feature flexible light beam angles that can be applied in various scenarios, Lextar said.

In addition, Lextar has cooperated with Future Taiwan Advanced Electronics to develop high-power UV-C LED disinfection modules for use in negative-pressure hospital wards, the company said.

Moreover, Lextar has provided UV-C LED air disinfection modules for the top-3 Japan-based vendors of air conditioners and air purifiers as well as US- and Europe-based vendors of electric home appliances. Lextar has also provided UV-C LED modules for international vendors of cleaning robots and kitchenware for use in surface disinfection as well as modules used to disinfect static water. In addition, the company has developed UV-C LED modules to be matched with faucets to disinfect flowing water.

Currently, about 9% of Lextar's consolidated revenues come from its UV-C LED product line.

LED packaging service provider Everlight Electronics has cooperated with Institute of Biomedical Sciences under Academia Sinica to publish the finding that 275nm UV-C light is more effective for destroying SARS-CoV-2 than 222nm and 254nm light. The company has developed 275nm UV-C LED disinfection modules for use in air conditioning and air purification, and has claimed these UV rays kill 99.9% of COVID-19 viruses.

LED lighting maker Ledtech Electronics has become a Taiwan sales agent for Philips lighting products equipped with UV-C LED modules and, in addition, developed UV-C LED disinfection products for sale under its own brand BioLED. The company aims to hike the revenue proportion for its UV-C LED product line from below 2% in 2021 to 10-15% in 2022.
