20090010016 | VEHICLE LIGHTING DEVICE - A vehicle lighting device is mounted in a bicycle. The lighting device includes a cantilever, a light-emitting lamp, and a power generating unit. The cantilever is fixed on a frame of the bicycle, so as to support the power generating unit to urge the power generating unit against a wheel of the bicycle constantly. The power generating unit includes an induction coil winding, a magnetic rotor, and a roller. The induction coil winding is wound around a winding axis. A rotating axis of the magnetic rotor is perpendicular to the winding axis. When wheels of the bicycle rotate, the roller and the magnetic rotor are driven to rotate relative to the induction coil winding, such that the induction coil winding generates an inductive electric power, which is supplied to the light-emitting lamp. Thus, a low-cost and labor-saving vehicle lighting device is developed. | 01-08-2009 |
