Patent ID: 7798684

Claim:
A pole system for a LED based lighting fixture comprising: an elongated substantially vertical support pole; said lighting fixture being adjacent a first upper end of said support pole and having at least one LED panel, wherein said at least one LED panel indirectly or directly illuminates from said lighting fixture; a cooling channel formed by a substantially vertical elongated shaft extending from a first opening proximate said first upper end of said support pole to a second opening proximate a second lower end of said support pole, said first opening being in flow communication with said second opening, said light fixture having said at least one LED panel externally sealed from and positioned adjacent to said elongated shaft at least partially between said first opening and said second opening, wherein said light fixture is not in fluid communication with said elongated shaft while maintaining thermal conductivity with said elongated shaft; a heat sink wall in thermal contact with said at least one LED panel and said shaft; whereby a cooling convection flow of air passes into said second opening and through said cooling channel and past said heat sink wall to exit at said first opening, thereby cooling said at least one LED panel when said at least one LED panel is in operation.
