Automatic power-generating device for decorative lamps |
摘要 |
An automatic power-generating device for decorative lamps has a weight-distributing plate or a heavy weight inside. Rotation of an exterior object produces an eccentric force (a centrifugal force) to rotate the weight-distributing plate or the heavy weight together with a coil and a magnet. The coil and the magnet rotate at different speeds due to the law of inertia to force magnetic field produced vicissitudes and to generate an inductive current (based on a principle of electromagnetic induction) to supply decorative lamps with power for lighting. Thus, the automatic power-generating device is able to save electricity and is convenient to be installed.
