摘要： A lamp unit is provided with a projecting portion on the inner wall of the lamphouse in the vicinity of the arc portion. The lamphouse is ventilated by the van provided at one end of the lamphouse and the vent provided at the other end. The inner diameter of the lamphouse at the arc portion provided with the projecting portion is smaller than that of both end portions, so that the flow velocity of the air passing through the lamphouse is higher in the vicinity of the arc portion, which produces a heat of a high temperature. Even if the lamp is horizontally installed, which lowers the heat dissipation efficiency, since the lamp is adequately air-cooled, an extreme temperature rise is prevented. The lamphouse is removeably mounted, and the lamp is mounted in a cartridge. The cartridge may be inserted into the lamphouse for replacement of the lamp.
