Title:
ULTRAVIOLET LIGHT IRRADIATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/073884
Kind Code:
A1
Abstract:
The present invention aims to provide a P–MP ultraviolet light irradiation system that can obtain effects such as the impartial sterilization of each target irradiation area, ensure safety, and improve work efficiency. The ultraviolet light irradiation system 301 according to the present invention is provided with: an ultraviolet light source unit 11 for generating ultraviolet light; N (where N is a natural number of at least 2) irradiation units 13 for irradiating N target irradiation areas AR with the ultraviolet light; an optical switch 12–2 for switching the path of the ultraviolet light to the paths 14 leading to the respective irradiation units 13; and a switching control unit 15–2 for setting the switching timing for the optical switch 12–2 on the basis of at least one out of the ultraviolet light transmission loss of each of the paths 14, the size of the irradiation area irradiated with ultraviolet light by the irradiation units 13, and the time required to deactivate the target irradiation areas AR.
