On the other hand, the shutter 4a that dotted line is represented in Fig. 4 is under the state of closed posture, and shutter 4a is in the lamp house RR and the position of the gap disposed adjacent of said ventilation usefulness relation.Therefore, after being flowing in gap through said ventilation usefulness and flowing in the lamp house RR of the cooling air of being represented by no arrows among Fig. 4, the shutter 4a that route is closed posture stops.That is, the shutter 4a of closed posture covers the stream of the cooling air that arrives ultraviolet lamp 6.Route is closed cooling air that the shutter 4a of posture covers to other local outflows, and the air quantity that arrives the cooling air of ultraviolet lamp 6 descends.
But as stated, when shutter 4a was in closed posture, the ultraviolet ray of ultraviolet lamp 6 output descended.Under state of this low output, if when being open mode with shutter 4a same strong cooling air cooling ultraviolet lamp 6, then become supercooling, cause the action of ultraviolet lamp 6 unstable.
Be directed to this, as stated, descend through make the air quantity of the cooling air that arrives ultraviolet lamp 6 during for closed posture at shutter 4a, thereby carry out proper cooling while can guarantee the operating stably of ultraviolet lamp 6.
