Abstract:
An LED lamp has a housing comprising a heat conductive body arrayed about a longitudinal axis with a tubular projection extending therefrom coaxial with the longitudinal axis. The tubular projection has a distal end attached to the heat conductive body and a proximal end opposite thereto. A motor is positioned within the tubular projection and has a tubular, vaned fan blade operatively connected thereto. A plurality of LED components is attached to an outside surface of the tubular projection at the proximal end. An air inlet is formed at the proximal end of the tubular projection and a plurality of air outlets are spaced about the tubular projection between the distal end of the tubular projection and the LED components. A base is operatively attached to the housing for attachment to a power supply.
