Abstract
A lighting fixture, such as a recessed or can type lighting fixture, has an external housing containing a number of LEDs used to provide light. The LEDs are connected to a power supply, and are mounted on a heat sink that includes heat-dissipating fins that are oriented vertically within a vertical portion of an internal flow tube. The internal flow tube may be U-shaped, with entry and exit points on opposite ends of the flow tube. The external housing and flow tube are oriented so as to create a path for air to rise along the heat sink as it is heated then flow back down along the unheated path of the flow tube. An air mover may also be placed in the flow tube to provide further air flow through the flow tube.
