Title:
ULTRAVIOLET LIGHT IRRADIATION SYSTEM AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/276148
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an ultraviolet light irradiation system that is easy to operate and makes it possible to avoid deterioration of a material due to ultraviolet light. An ultraviolet light irradiation system according to the present invention comprises: one ultraviolet light source unit 11 that generates ultraviolet light; an irradiation unit 13 that irradiates only a predetermined location (an irradiation location ste) with the ultraviolet light; an optical fiber 14 that transmits the ultraviolet light from the ultraviolet light source unit 11 to the irradiation unit 13; a sensing unit 16 that monitors the state of the irradiation location ste and outputs the result as monitoring information; and an irradiation control unit 15 that uses the monitoring information as a basis to control the output of the ultraviolet light from the ultraviolet light source unit 11.
