Developed high-output deep ultraviolet (UVC) LED assembly products for sterilization, confirming a 99.99% inactivation effect on the novel coronavirus.

Citizen Electronics Co., Ltd. (Headquarters: Fujiyoshida City, Yamanashi Prefecture; President: Kanetaka Sekiguchi) has developed a "High-Power UVC LED Assembly Product for Sterilization" (hereinafter referred to as UVC LED Assembly Product) equipped with a high-output deep ultraviolet (UVC) LED that has a peak emission wavelength of 265nm, which is said to have high sterilization efficiency, and will begin mass production shipments in mid-April 2022.
■ Main Features
1. By adopting a high-reflectivity reflector, it enables uniform irradiation of the sterilization area for efficient sterilization.
2. Equipped with a high-output deep ultraviolet (UVC) LED at 265nm, which has high sterilization efficiency.
3. A high-output assembly product that allows for the replacement of sterilization lamps that have mercury content issues.
4. Dustproof and waterproof functionality (equivalent to IP54) allows for use in various environments. *Only for UVM001.
This product has been jointly evaluated with Fujita Medical University (Department of Medicine, Virology and Parasitology, Associate Professor Kawamoto) for its inactivation effect on the novel coronavirus (SARS-CoV-2), confirming that it has high effectiveness as an assembly product rather than as a standalone UVC LED. (Details of the tests are published in our press release.)
