ABSTRACT:
A self-generating hand-held flashlight including the optional use of battery power. The flashlight includes a tubular body case that may be divided into three compartments. In a first compartment a generator utilizing a permanent magnet armature is mounted. This generator is electrically tied to a bulb at one end of the flashlight. The generator is powered by rotation of a central shaft coupled to a flywheel, the flywheel being located within a second and larger compartment of the flashlight body case. The flywheel is rotated by manual energy coupled to the flywheel through a power wheel and slip-clutch, both of which are also located within the second and larger compartment. Various manual means are used to rotate the power wheel. The flywheel is adapted to have a maximum inertia, thereby allowing it to rotate for a substantial period of time once initialized. A very favorable time ratio of light time to energy input time is achieved by using a high inertia flywheel that is properly balanced and mounted within the flashlight. Hence, a continuous source of light may be provided through the application of only short bursts of manual input energy. A third compartment of the flashlight housing may optionally include a battery that could be used as an alternative power source.
