ABSTRACT:
A portable mechanical light generating device includes an electrical generator located in a portable housing. The generator is activated by way of a rotatable shaft which rotates an armature within a magnetic field in order to produce electricity. A coil spring is adapted to be wound tightly and then slowly unwind. While unwinding, the spring turns a succession of gears in order to rotate the shaft associated with the generator. As a result, the slow unwinding of the spring allows the generation of electricity over sustained periods of time.
