Abstract: A light assembly includes a charge/discharge unit which is electrically connected to a control unit and a switch is electrically connected to the control unit so as to control the output of the control unit. A driving unit is electrically connected to the control unit and the charge/discharge unit so as to drive a light source. A connection port is electrically connected to the charge/discharge unit, the control unit, the driving unit and the light source so as to be connected with an electric appliance such as an energy generating device.

Abstract: An automatic electric power generating device for wheels includes a wheel hub and a housing. The wheel hub is provided with a first magnetic pole set and a second magnetic element. The first magnetic pole set has a spool, and left and right magnetic poles. The spool is winded with a coil having a guiding end thereof connected to an illuminating element installed at the wheel hub. The housing is provided with a first magnetic element and a second magnetic pole set. The second magnetic pole set has a spool, and left and right magnetic poles. The spool is winded with a coil having a guiding end thereof connected to a lighting device. Through rotations of the wheel, induction is generated between the driven and rotating magnetic pole sets and the magnetic elements.

Abstract: A luminous device capable of automatically generating power includes a set of induction coils with one end connecting to a luminous element and placed inside a light conductor which is fastened onto a steel wire of a wheel via a fastening structure; one or more than one magnets are disposed inside a magnet case corresponding to the set of induction coils. Therefore, when the wheel spins, it drives the light conductor to rotate thereby generating electric current between the set of induction coils and the magnet to further drive the luminous element. In addition, the light conductor guides the light source of the luminous element outwardly so as to generate luminous and warning function.

Abstract: A wheel made of an optically conductive material is provided at a hub thereof with a power supply device. A plurality of light emitting elements are connected to the power supply device and separately disposed in spokes of the wheel. Alternatively, a plurality of optically conductive elements, which may have a specially designed configuration, shape or color, are separately fixedly mounted on the spokes of the wheel with the light emitting elements mounted therein. Light beams emitted from the light emitting elements are transmitted outward via the spokes or the optically conductive elements to provide a visually good warning effect. Such wheel is particularly suitable for use with bicycles, tricycles, and strollers.

Abstract: An automatic wheel-driven generating device mainly includes a base fixedly mounted on a wheel around an axle thereof and provided with a centered hollow column and one or more radially extended hollow pipes for each receiving a light-emitting element therein; a winding reel enclosed between left and right magnetic poles and fixedly mounted on the hollow column; and a magnet holder having a cap screwed into a center thereof and being fixedly mounted on the axle. The magnet holder carries magnets and is associated with the winding reel and the magnetic poles without contact with them. When the wheel rotates, the winding reel and the magnetic poles on the base rotate along with the wheel relative to the magnet holder that is unmovably fixed on the axle, so that an induced current is produced to drive the light-emitting elements to emit light beams.
