摘要： In lamp unit 10 having light source lamp 1, reflector 2 for reflecting light from light source lamp 1, reflector holding member 11, and reflector cover 15, a plurality of cooling holes 18a are formed in a region of reflector holding member 11 provided with lamp unit positioner 16a. Cooling holes 18a are open toward an upper bulb area, a lower bulb area, and a cathode of the light source lamp, respectively. Stud 22a for fixing reflector holding member 11 has a throughhole extending at the center thereof, so that cooling air fed from high static pressure blower 27 can be sent to cooling holes 18 through tube 28 and the throughhole of stud 22a, thus efficiently cooling the upper bulb area, lower bulb area, and cathode of light source lamp 1 in a concentrative manner with a small amount of air. Thus, the resulting lamp unit, provided by the present invention, can reduce the amount of air required for cooling the lamp, and can use a high static pressure and small fan.
