Since the short arc lamp 10 generates a large amount of heat during operation, the short arc lamp 10 and the conductive heat radiating member 2
1 and 22 need to be cooled, and although not shown, they are forcibly air-cooled by a cooling fan. Here, the heat radiation method of the short arc lamp 10 will be described. In the short arc lamp 10, since the cathode side power supply member 15 is in contact with the mounting hole 221 of the conductive heat dissipation member 22, the heat generated during lighting is transmitted through the cathode side power supply member 15 to the conductive heat dissipation member 2.
The heat is transferred to the second radiating fin 22a and is radiated. Further, in the short arc lamp 10, since the anode-side power supply member 16 is also in contact with the mounting step 211 of the conductive heat dissipation member 21, the heat generated during lighting is generated via the anode-side power supply member 16.

At least one of the conductive heat dissipating members 21 and 22 is fixed by a screw or the like, and is arranged in contact with the outer peripheral surface of the short arc lamp 10. Here, the outer peripheral surface of the short arc lamp 10 refers to the outer peripheral surface of the cathode-side power supply member 15, the outer peripheral surface of the body 11, and the outer peripheral surface of the fixing member 17. The insulating heat radiating member 4 is made of, for example, high-purity Al 2 O 3 , A in order to prevent electric discharge between the conductive heat radiating members 21 and 22 and to perform good heat radiation.
1N, BN, Si 3 N 4 and the like. In the short arc lamp 10, since the body 11, the cathode-side power supply member 15, and the fixing member 17 have different diameters, the outer peripheral surface thereof is uneven. For this reason, the electrically insulating heat dissipation member 4 also
The short arc lamp 10 has an uneven shape so as to mesh with the unevenness on the outer peripheral surface. Therefore, the electrically insulating heat radiating member 4 and the short arc lamp 10 are in contact with each other over a wide range of the outer peripheral surface of the short arc lamp 10.

The heat is transferred to the radiating fins 21 a of the conductive radiating member 21 via the anode-side power supply member 16 to be radiated. Further, since the electrically insulating heat radiating member 4 is in contact with the outer peripheral surface of the short arc lamp 10 over almost the entire circumference, the heat generated during lighting is transferred to the electrically insulating heat radiating member 4 as well. The heat is also radiated from the electrically insulating radiating member 4 itself. Besides,
The electrically insulating heat radiating members 4 are electrically conductive heat radiating members 21 and
2, the heat radiation effect can be enhanced. Therefore, since the cooling efficiency of the short arc lamp has been increased, it is possible to light up with twice or more inputs as compared with the conventional lamp device, and it is possible to greatly increase the light amount. Further, if a light amount equivalent to that of the conventional lamp device is obtained, the size of the conductive heat dissipating members 21 and 22 can be reduced. Therefore, the size of the lamp device can be reduced.
