Title:
ULTRAVIOLET LIGHT IRRADIATION SYSTEM AND ULTRAVIOLET LIGHT IRRADIATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/215110
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an ultraviolet light irradiation system that can ascertain the state of a region irradiated with ultraviolet light and thereby emit or block the ultraviolet light; and an ultraviolet light irradiation method. An ultraviolet light irradiation system 301 according to the present invention comprises: an ultraviolet light source unit 11 for generating ultraviolet light; N irradiation units 13 (N is a natural number) for irradiating an irradiation object Ar with the ultraviolet light; a sensor unit 31 for detecting the presence or absence, on the irradiation object Ar, of an avoidance object for which exposure to the ultraviolet light should be avoided; and a blocking unit 30 for interrupting the irradiation of the ultraviolet light from the irradiation units 13 to the irradiation object Ar if the avoidance object is present on the irradiation object Ar.
