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.
Claims8
In combination, a high intensity lamp and luminaire assembly comprising,
- (a) a lamp heat removal means comprising a heat exchanger with multiple metal fins and at least one metal tube running through said fins, and a heat transfer medium circulating in said at least one tube,
- (b) wherein the heat exchanger is mounted at a point of highest heat concentration between said high intensity lamp and a reflective surface of said luminaire,
- (c) a light ray dispersion means wherein the heat exchanger fins are arranged so as to minimize light ray convergence back onto a light source within said high intensity lamp,
- (d) a condensate removal means wherein the heat exchanger is positioned to create a gravity fed drip path which directs condensate forming on the heat exchanger to a location separate from that of water vulnerable lamp components.
