Abstract
PURPOSE:To contrive draft of optimum air flow to a lamp and the other parts necessitating cooling by providing a discharge lamp controlling plate covering at least one part of a converging side of the discharge lamp and arranging this discharge lamp controlling plate to the position facing the approach direction of cooling air. CONSTITUTION:A short-arc type discharge lamp 1, an elliptic converging mirror 3 having a bottom aperture part 3a perforated with the stem part 1c of the discharge lamp 1 and a means which consists of the intake hole 7a of a housing 7, the draft hole 13d of a partition plate 13, the draft hole 14a of an air controlling plate 14 and an exhaust fan 10 and allows the inside of an equipment to be forcedly air-cooled are provided. An air controlling plate 15 covering at least one part of the converging side of the discharge lamp 1 is provided and this air controlling plate 15 is arranged to the position facing the approach direction of cooling air. As a result, air flow of the lower limit necessary for cooling the lamp can be preset and insufficient cooling for the converging mirror is not caused.
