Abstract
An LED UV sterilization device, including a lens assembly and a light source assembly; the lens assembly includes a plurality of lenses of different materials suitable for light of different wavelengths; the light source assembly includes a visible light source assembly and an ultraviolet light source assembly. Visible light irradiated by the visible light source assembly and invisible ultraviolet light irradiated by the ultraviolet light source assembly pass through lenses of corresponding materials and form an overlapped light spot, so that an irradiation location of the invisible ultraviolet light is indicated by the visible light. The LED UV sterilization device not only realizes safe disinfection and sterilization, but also visualizes the sterilization process. The sterilization process is safer and more reliable, and the sterilization area is more accurate.
