20100172143 | Puck Type Light Fixture - A puck light fixture has a puck shaped housing, the interior divided by a partition into a circular central compartment encompassed by an outer compartment. Air conduits closed to the housing interior admit flow of ambient air between top and bottom openings in the housing. The air conduits are in heat exchanging relationship with the partition for dissipating heat generated by a lamp in the central compartment and thereby lowering the operating temperature of electrical wiring and connectors in the outer compartment so as to allow use of lower rated wiring for on site hard wiring of the puck fixture. | 07-08-2010 |
