Abstract

PURPOSE: To efficiently radiate heat from a ventilating passage and a fin by forming the ventilating passage between a ventilating plate provided on an opposite side of a surface to receive light from a cold mirror and providing a light-intercepting radiation fin in the ventilation passage with the fin part facing the mirror. CONSTITUTION: Air sucked from a ventilation hole 6 a flows through a ventilating passage between a light-intercepting radiation fin 9 provided on a ventilation plate 8 and a flat reflecting mirror 3 of a cold mirror and is exhausted from an exhaust fan 10. A part of the air sucked from the ventilating hole 6 flows in a gap between the side wall of a lamp body 6 and the ventilating plate 8, and its other part flows toward a lamp 1 or a filter 5 and is exhausted from the exhaust fan 10. The light-intercepting radiation fin 9 is provided with its fin part facing the flat reflecting mirror 3. Thereby, heat can be efficiently radiated from the ventilating passage and the fin 9.
