  • Light emitting roller skate wheels
    Patent number: 4648610
    Abstract: This invention relates to an improved method of causing light to be emitted from a roller skate wheel. The light is produced with energy obtained from the motion of the wheel. This invention uses a permanent magnet and an electrically conducting coil, wound around a magnetically permeable core, to produce electrical energy. The energy is used to produce an electric current through a light emitting diode, which results in light being emitted from the body of the wheel when the wheel rotates.
