Abstract:
1. A puck light comprising a puck housing including a housing top and a housing bottom, an outer wall between said top and said bottom, a generally annular partition between said top and said bottom defining a central compartment and an outer compartment, said partition substantially closing said outer compartment against substantial flow of air from said central compartment, a terminal connector block in said outer compartment, a lamp socket in said central compartment electrically connected to said terminal block for powering a lamp supported in said socket, air passages defined through said partition between exterior vent openings in said top and said bottom, said passages being closed to each said compartment, such that ambient air flowing through said passages is in heat exchanging relationship with said partition for reducing heat flow across said partition from said central compartment thereby to maintain relatively low operating temperatures in said outer compartment relative to said central compartment.
