ABSTRACT:
A roller skate wheel has an inner body portion for securement to the axle of the roller skate and an outer body rotatable about the inner body on appropriate bearings. A permanent magnet is secured to the inner body in flux coupling relationship with electrically conducting windings carried on the outer body. When the wheel rotates, electricity is generated on the windings and used to energize light emitting diodes carried on the outer body of the wheels. The generated electricity is of the alternating type and since the light emitting diodes are essentially polarity-sensitive, they will be energized on only positive half cycles of the current to thereby provide a flashing or stroboscopic effect.
