ABSTRACT:
An illuminating wrist exerciser includes upper and lower casing members, a ring, a rotor, a magnetic element, an illumination control circuit board, a plurality of illuminators, and a coil holder. The upper and lower casing members mate each other to form an interior space receiving the rotor therein. The upper casing member forms in a top portion thereof an opening to partially expose the rotor. Opposite ends of the rotor are rotatably coupled to the ring surrounding the rotor. The magnetic element is mounted to the ring. The illumination control circuit board and the coil holder are received in a recess defined in one of the ends of the rotor. The coil holder forms a bore in which the magnetic element is received. The coil holder carries thereon at least one pair of coils. The illuminators are distributively arranged on an outer surface of the rotor and are electrically connected to the illumination control circuit board. Electrical power is induced by the magnetic interaction between the coils of the coil holder and the magnetic element and is fed to the illumination control circuit board, which in turn controls the lighting/darkening of the illuminators to thereby provide a power-generation, illuminating wrist exerciser.
