Spiral-path chimney-effect heat sink

A spiral-path chimney-effect heat sink cools an LED light bulb by increasing the length of the path over which heated air rises between two coaxial tubes. A tube top is attached to one end of the tubes. A light emitting diode (LED) is thermally coupled through the tube top to the inner tube. There are window openings below the rim where the outer tube attaches to the tube top. A convection current path guide is disposed between the inner and outer tubes. The convection current path guide is a spiral wire that causes rising air to follow a longer spiral path around the heated inner tube before the air exits the heat sink through the window openings. An Edison screw base is attached to the end of the inner tube opposite the end attached to the tube top. The coaxial tubes can be cylindrical tubes, conical tubes or square tubes.
