PROBLEM TO BE SOLVED: To provide a rotating lighting device which can be recognized from many directions to maintain sufficient safety, enabled to secure a safety by stably irradiating light for long time without using external power source like a cell. SOLUTION: The rotating lighting device is composed of a disc-shaped permanent magnet, and a rotating wheel, rotatably supported against the disc-shaped permanent magnet, having coils wound so as to face the outer peripheral surface of the disc-shaped permanent magnet, and having a plurality of light emitting bodies mounted on its peripheral rim of which, light emitting directions alternates. The disc-shaped permanent magnet is fixed near to a rotating body, and the rotating wheel rotates according to the rotation of the rotation body, making the disc-shaped permanent magnet act as a center of rotation, and the light emitting bodies ate made to emit light in alternating directions. |
