PURPOSE: An LED lighting device is provided to minimize a light absorbing rate, prevent deformation of the lighting device, reduce production costs, and directly apply power to a converter or each LED, thereby obtaining stability. CONSTITUTION: A metal base(140) includes a connection pin(141) which is made of insulating materials so that the metal base is inserted to a socket while the metal base surrounds both ends of a glass tube. A plurality of heat emitting wing parts is formed on the surface of the metal base. A plurality of LEDs is mounted on a PCB. External power is applied by detachably connecting a connector connection pin(170) to a connector connection groove. |
