PURPOSE: An optical semiconductor based lighting device is provided to control various operations such as the inspection of a lighting state, light intensity, and illumination by using a portable terminal. CONSTITUTION: A housing(320) receives a substrate. Multiple semiconductor optical devices(500) are mounted on a panel(100). One end of a main tilting unit is rotatably mounted along the edge of the panel. A light diffusion member diffuses light emitted from the semiconductor optical device. A guide rail guides the movement of a moving block by being formed on a bottom plate(900). |
