PURPOSE: A led lighting device is provided to efficiently emit a heat created from the led by transferring the heat from the led to a housing through a socket. CONSTITUTION: An optical source module(110) includes a LED light source, a metal substrate and a heat transferring member. The metal substrate is combined with the LED light source. The heat transferring member is thermally combined with a socket(120) and the metal substrate. The socket has a plurality of photometric surfaces and a plurality of module supporting surfaces. A plurality of photometric surfaces is connected each other to have a predetermined angle or a predetermined curvature. A plurality of module supporting surfaces respectively supports a plurality of optical source modules to the different angle. A housing(130) is detachably combined with the socket by a docking unit. |
