  • Moisture shedding liquid cooled floodlight fixture
    Patent number: 5199784
    Abstract: A series of compact, interchangeable, sloping heat exchangers (22), (48, (54), and (58) which when combined with various floodlight fixtures eliminate radiated heat from the floodlight fixture, in combination with drip accumulators (44) which collect condensed water from the atmosphere that collects on the cooling surfaces of heat exchangers (22) (48), (54) and (58). Drip accumulator nozzles (46) discharge the condensed water to a desired location and prevent water damage from occurring to vulnerable floodlight fixture components.
