Abstract: 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.

Abstract: A light generating device utilizes a large centrally located magnet which is mounted to slide past a magnet pickup or current induction wire which may be preferably mounted at a center point of travel in a tubular housing having a tubular chamber through which the magnet travels. A pair of elastomeric bumpers are located each at the end of the tubular chamber which may be inside or outside the flashlight. The result is a device which both facilitates the manual movement of the flashlight body so that the magnet slides past the center magnet pickup or current induction wire, and also conserves the residual momentum of the magnet once it has traveled past the magnet pickup or current induction wire by providing a bumper and spring to conserve some of the mechanical energy going in the other direction. Ninety second of manual activation enables about five minutes of illumination.
