ULTRAVIOLET RAY IRRADIATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet ray irradiation apparatus in which a window material of a lamp house can be cleaned easily. SOLUTION: The ultraviolet ray irradiation apparatus is provided with: an ultraviolet lamp 1 in which an internal electrode is arranged along the central axis of a lamp tube and an external electrode 11 is arranged around half of the outer periphery of the lamp tube and opposed to the internal electrode; the lamp house 10 which has the window material 5 on the undersurface side thereof and houses the ultraviolet lamp 1; and an apparatus housing 20 for housing the lamp house. The lamp house is supported in the apparatus housing by a rotation mechanism 30 which can rotate the lamp house around a rotary shaft 31 in the axial direction of the ultraviolet lamp from/to a position that the ultraviolet ray emitting surface of the ultraviolet lamp takes a downward-looking attitude to/from another position that it takes an upward-looking attitude and can kept such attitudes.
