Therefore, the airflow supplied to the duct 14 is controlled by the airflow control plate 18, and the airflow flowing towards the center in the longitudinal direction of the duct 14 increases. Since it is formed in a direction of about 60' to 90 degrees from the horizontal plane inside the base on the fan case II side to the vertical direction which is the axial direction of the axial fan 10, the airflow exhausted from the discharge port 8 is The cooling air has a uniform wind speed over the entire length in the longitudinal direction, and even if the arc tube length of the high-pressure discharge lamp 1 is long, the amount of air flow in the longitudinal direction of the lamp 1 is small, and the cooling capacity is uniform, so that the high-pressure discharge lamp 1 The surface temperature distribution in the longitudinal direction can be made uniform, and the lighting state of the high-pressure discharge lamp 1, that is, the ultraviolet irradiation ability can be stabilized.

運転を個々に制御することもできる。In addition, when each duct device 7 is divided into a plurality of units in the longitudinal direction, the drive of each fan 10 is different from that of the high-pressure discharge lamp 1 because, for example, heat generation is different between both ends and the center of the high-pressure discharge lamp 1. Since heat generation differs at each location in the longitudinal direction of the high-pressure discharge lamp 1, adjustment settings are made corresponding to each location in the longitudinal direction of the high-pressure discharge lamp 1. The operation of each fan 10 can also be controlled individually.

They form air volume control plates in the width direction, and the air volume control plates are arranged at an angle of about 60° to a vertical direction, which is the axial direction of the axial fan, from the horizontal plane inside the base on the fan case side of the air volume control plates. Since it is formed in the direction of 9G', with a simple configuration, the speed of the cooling air from the duct outlet is approximately equal over the entire length in the longitudinal direction of the duct outlet, and a uniform air volume can be obtained. The cooling capacity can be made uniform by reducing the difference in air ventilation in the direction, and the surface temperature distribution in the longitudinal direction of the high-pressure discharge lamp can be made uniform.
