HEAT SINK FOR PACKAGING LIGHT EMITTING DEVICE

摘要

PURPOSE: A heat sink for packaging a light emitting device is provided to obtain an excellent heat radiation effect by forming heat radiation protrusions having at least one penetration hole. CONSTITUTION: A heat sink(300) for a light emitting device package comprises a heat radiation projection(310) equipped with a plurality of heat radiation protrusions. The heat radiation projection are arranged to maximize radiation efficiency through air. The heat radiation projection has a horizontal penetration hole and a vertical penetration hole. The heat radiation projection is divided into nine partitions by penetration holes.
