摘要
A stage light instrument for providing efficient cooling of electrical components (40, 42) and a high wattage lamp (101). The facility includes a base enclosure (10) and a lamp enclosure (22) joined for pan and tilt movements by a forked hollow connecting member (14). The cylinder part (36) of the connecting member (14) is apertured and encased within the base enclosure (10) in bearings (65, 66) and in a plenum (34). A pair of tubes (68, 70) each with an air passage (72, 74) corporate with bearings (69, 71) to join the arms (18, 20) of the forked connecting member (14) to the lamp enclosure to provide air passage from the base enclosure (10) to the lamp enclosure (22). A fan (12) mounted in the base enclosure (10) draws air over electrical components (40, 42) and forces the air into the forked connecting member (14). Air is the routed through various ducts (86, 88, 98), hoods (120) and baffles (122) onto the high wattage lamp (101) and other lamp apparatus (90,92, 112) housed within the lamp enclosure for cooling.
