Abstract

A rotary motion powered system for energizing light emitting diodes is taught that utilizes a permanent magnet generator ( 20 ) located within a vehicle wheel ( 64 ) for producing the requisite electric power. The generator consists of two main elements: a rotating portion ( 26 ) and a stationary portion ( 28 ). The rotating portion utilizes a base ( 30 ) that is attached directly to an adapter base ( 72 ) attached to the vehicle wheel, and the stationary portion includes a counter weight ( 62 ), thus permitting this portion to remain horizontal when the wheel is rotating. An ac/dc bridge rectifier ( 22 ) is in electrical communication with the generator output to change the alternating current produced by the permanent magnet generator to direct current. A number of light emitting diodes are disposed within a vehicle wheel member and are powered by the direct current power, thereby producing an unusual and unique visual effect when the wheel is rotating.
