PROBLEM TO BE SOLVED: To provide a lighting system without putting a reflecting plate in contact with a lamp by the rotational movement of the reflecting plate and causing radiation in an irregularly lateral direction. SOLUTION: A hole with a female screw is provided on the ceiling of a lighting system outer frame 3. A screw 10 is threaded into the hole to form a downward protrusion. On the ceiling of a reflecting plate 8, a hole 22 is provided. When the reflecting plate 8 is fixed to the ceiling of the lighting system outer frame 3 with a screw 9, the end of the screw 10 is fitted into the hole 22. In this way, the reflecting plate 8 is positioned and the center of the lamp 7 corresponds to the center of a cutout in the reflecting plate 8. The lamp 7 is thus prevented from contacting or approaching the cutout at its end in the reflecting plate 8. |
