PURPOSE: A heat sink for an LED lamp is provided to maximize heat radiation effects by forming a plurality of heat radiation units with a wave shape. CONSTITUTION: A plurality of heat radiation units(320) is formed on the outer circumference of a heat sink body(310). The heat radiation unit is comprised of a plurality of radiation fins(321). A protrusion(324) is formed on both sides of the radiation fin with a semicircular shape. A plurality of heat radiation protrusions(322) is formed on the outer surface of the heat radiation unit. The heat radiation protrusion includes one or plural heat points or linear protrusions. The heat point is formed on the outer surface of the heat radiation unit. The linear protrusion is formed on the outer surface of the heat radiation unit in a longitudinal direction. |
