<P>PROBLEM TO BE SOLVED: To prevent the deformation of light reflector, and to keep the temperature in housing to a proper degree. <P>SOLUTION: The ultraviolet irradiator 7 is constituted so that an ultraviolet lamp 30 stored in a water-cooling jacket 31 and a main light reflector 32 for reflecting the light emitted from the ultraviolet lamp 30 are stored in a housing 22 and the direct light emitted from the ultraviolet lamp 30 and the light reflected from the main light reflector 32 are emitted from the ultraviolet irradiator. The ultraviolet irradiator further includes: a water cooling mechanism 33 used as a heat recovering mechanism for recovering the heat of the main light reflector 32 and radiating the recovered heat to the outside of the housing 22; and a heat sink 34 for transferring the ambient heat in the housing 22 to the water cooling mechanism 33 and recovering the transferred heat in the water cooling mechanism 33. <P>COPYRIGHT: (C)2013,JPO&INPIT |
