摘要： An apparatus for cooling a light source within a building or vehicle having an air conditioning system includes a housing for surrounding the light source and structure for delivering a stream of cooled air into the housing from the air conditioning system. The structure for delivering a stream of cooled air is preferably a conduit connected to the air conditioning system. The portion of the air conditioning system to which the conduit is connected is preferably an air carrying duct. Where the light source is a light fixture on a ceiling, the housing is essentially frustrum shaped and attached to the ceiling around the light fixture, and has a translucent lens extending over its bottom surface. The housing has an open base and there are three spaced apart lenses at the open base for retaining heated air within the housing, at least one lens being perforated to permit air to enter and exit the housing, the conduits delivering the stream of cooled air between the lenses to absorb and carry away heat. A height adjusting mechanism is preferably provided to adjust the distance between the lens and the open base of the housing. The height adjusting mechanism includes a threaded rod, one end of which is rotatably fit into a threaded bore in the housing and the other end is attached to a knob, such that rotating the knob changes the above-mentioned distance.
