Developed an engineering scheme using UV-LED as an efficient and high-speed disinfection and sterilization light source

Based on deeply research and development in the field of LED technology for many years, we developed an engineering scheme using UV-LED as an efficient and high-speed disinfection and sterilization light source, and took wardrobe elimination as the application scenario. During the epidemic period, we made contributions to the fight against the epidemic and won the attention and recognition of the society. This case uses 265 nm wavelength LED as deep ULTRAVIOLET light source, develops an innovative design with laminated silicon reflective cup as the main packaging structure, and makes a prototype uV-LED array, which is installed in the self-designed wardrobe to achieve elimination function. By international professional certification company SGS test, can achieve in 1 minute sterilization 99.99% of the effectiveness, in the market all kinds of disinfection products crown.  Po Leung Kuk in Hong Kong has used it in three of its schools and held press conferences to publicize the results.
