PURPOSE: A light semiconductor-based lighting device is provided to minimize the weakening of the fastening force of a fixing device upon the long period of time passage, by mutually combining a head of a tilting unit end and a rail of the housing external side. CONSTITUTION: At least one semiconductor optical device is arranged in the housing(100). A rail which is dented to inner side is formed in at least one side of the exterior surface of the housing. At least one protruded part, which is protruded along a longitudinal direction of the rail, is formed in a surface which faces the rail. A tilting unit(200) is combined to the rail and controls the slope of housing. The tilting unit is sliding combined in the rail and includes the head which is connected to an object. |
