PURPOSE: By using a plurality of heat radiation fins formed the created heat in the metal material in the LED radiation, the indirect lighting LED fluorescent lamp effectively releases heat. CONSTITUTION: A cover(111) of the u-shaped is that cut-out across the opened both ends is formed in the top. The metal material(130) releases heat the heat created in the LED radiation. In the metal material, a plurality of heat radiation fins(133) is formed. The protrusion(151) is perpendicularly projected from the lower part of the metal material. |
