PURPOSE: A heat sink for an LED lamp and a manufacturing method thereof are provided to improve heat radiation performance of the heat sink by rapidly radiating heat of a conductive plate. CONSTITUTION: A conductive plate (11) has a plate shape. Multiple heat radiation fins (25) are fixed on one side of the conductive plate. The heat radiation fin is extended a fixed length upwardly from the conductive plate. A heat radiation pipe (24) has an extended length which is larger than the extended length of the heat radiation fin. The lower part of the heat radiation fin is fixed on the conductive plate by penetrating the conductive plate. |
