AIR-COOLED HEAT SINK, AND LIGHT-EMITTING DIODE LAMP USING SAME

摘要

The present invention relates to an air cooled heat sink having a lattice structure in which a copper tube passes through aluminum heat-sink plates and dissipates heat through heat conduction and the natural convection of air inside the structure; and a light-emitting diode lamp using the air cooled heat sink. The air-cooled heat sink comprises: a horizontal sink part including first and second horizontal sinks, wherein the first horizontal sinks have a diameter greater than the second horizontal sinks, and the second horizontal sinks are each disposed between two adjacent first sinks; and a vertical sink part including first and second tubes, one end of which is closed, and third tubes, both ends of which are open, wherein the first and second tubes pass through and are integrated with the first and second horizontal sinks, and the third tubes pass through at least the first horizontal sinks.
