Abstract:
A writing implement with dual illuminating ends comprising: a light transmitting case, a protective seat connected to a top end of the light transmitting case, a top illuminating module mounted within the protective seat, a light transmitting moveable seat mounted at the bottom of the protective seat, a bottom illuminating module mounted within the light transmitting moveable seat and a refill mounted within the light transmitting case and urged against the moveable seat, characterized in that an interior of the protective seat is mounted with the top illuminating module and the bottom illuminating module and the light transmitting moveable seat, structures of the top and bottom illuminating module are similar and are mounted asymmetrically, the top illuminating module is fixed at a top section of the protective seat and the bottom illuminating module is mounted within the light transmitting moveable seat, the moveable seat is movingly mounted at the bottom section of the protective seat, the top and bottom illuminating modules each include a light emitting diode, a light emitting seat, batteries, a battery seat, a metallic spring, and a metallic blocking nut to form circuits in parallel wherein the light emitting diode is located within the light emitting seat, and the light emitting seat is mounted on a top of the battery seat, the batteries are located within the battery seat, and the metallic blocking nut is mounted at the bottom of the battery seat, and the metallic spring is mounted between the metallic nut and the batteries, thereby when the refill exerts a force, a reaction causes the refill to move upward to push the moveable seat such that the blocking nuts of the two illuminating modules touches the batteries to form a closed circuit, which causes the two illuminating modules to illuminate, light from the modules travels from the top end of the protective seat to the bottom end of the moveable seat, and the light from the bottom end is refracted via an inner wall of the light transmitting case to produce an illumination effect.
