NONCONTACT SELF-GENERATING TYPE SAFETY WARNING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a noncontact self-generating type safety warning device promoting efficient power generation and capable of greatly reducing limitations on design and mountability and of being miniaturized without impairing safety. SOLUTION: The device comprises a rotor 1 with a magnetic body 3 attached thereto, a frame clamping the rotor 1 and journaling the portion of the rotor 1 near its center, and a safety warning lamp 5 including a light which is made to emit light by rotation of the rotor 1. A magnetic circuit 2 is mounted, via mounting members 23 and 24 made of magnetic substance, to a certain portion of the frame 4 located oppositely to the magnetic body 3, and the safety warning lamp 5 is made to emit light by electric power induced in the magnetic circuit 2 as the magnetic body 3 periodically approaches it with the rotation of the rotor 1.
