CONSTITUTION: A pair of enclosed caps(400) are combined with both sides of a heat sink(200) and a diffusion tube(300). The enclosed cap has a guide protrusion unit which is protruded to the outside. A pair of power sockets(500) are fitted to the guide protrusion unit. The power socket is electrically connected to a substrate and an electric wire. A brightness control unit differently controls the brightness of LEDs according to a current flow direction to a power socket. |
