Abstract: The LED Light Fixture with Inter-LED Flow-Through Cooling dissipates heat by placing two or more LEDs against a heatsink, spacing the LEDs apart from each other. The spaces between the LEDs are open to the heatsink below, creating air inlets into the heatsink. Air flows into the air inlets, passes by the fins of the heatsink, and exits through the top, bottom, or sides of the heatsink, depending on the orientation of the device. The result is airflow through the fixture, cooling the heatsink and the LEDs.
Abstract: The LED construction of the invention simplifies the thermal path for heat by directly connecting the LED and the heatsink, removing the circuit board from the thermal path. This is accomplished by a heatsink boss that protrudes from the heat sink, through an opening in the circuit board, and contacting the LED.
