Title:
UV IRRADIATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/073774
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a UV irradiation system with which it is possible to obtain effects such as sterilization, etc., that is fair between irradiation target regions, ensure safety, and improve working efficiency. This UV irradiation system 301 comprises: a UV light source unit 11 for generating UV light; an optical fiber 16 having one end connected to the UV light source unit and propagating UV light from the one end; one or a plurality of optical splitters 12-5 installed at arbitrary longitudinal positions of the optical fiber 16, the optical splitters 12-5 extracting a part of the UV light propagating through the optical fiber 16 at a prescribed splitting ratio; and irradiation units 13 for radiating the UV light reaching the other end of the optical fiber 16 and the UV light extracted by the optical splitter 12-5 at respective irradiation target regions AR.
