PURPOSE: A heat sink for an LED lamp integrated with a coupling hole is provided to increase the durability of a product. CONSTITUTION: A heat emitting unit(21) has a sealed section. A mounting surface(23) is placed on the external circumference of the heat emitting unit. A substrate where an LED(32) is installed is installed on the mounting surface. A plurality of heat emitting fins(22,22a) is projected toward the inside of the heat emitting unit. A coupling hole(4) is integrated with the internal center part of the heat emitting unit. A coupling pipe(6) is inserted into the coupling hole. |
