Abstract
A power-generating and illumination device for a bicycle comprises at least one permanent magnet 20 disposed onto wheel spokes (11, figure 1) to form a rotor and an induction coil assembly 30 mounted onto a fork (12, figure 1) for forming a stator. During the rotation of the rotor, the induction coil assembly 30 may be cut by magnetic lines of force to generate electrical energy for output to a light-emitting unit 50, which may be an LED. In between the induction coil assembly 30 and the light-emitting unit 50 is a control unit 40 including a wave detector 41, a wave filter 42, and a current limiting resistor 43 connected together to form a loop, thereby detecting and filtering polarity of voltage of the generated electrical energy and lowering the resonating frequency to maintain the service life and illuminative brightness. The current limiting resistor 43 may be adjustable to control and maintain the brightness of the LED 50. A flasher 44 may be supplied between the current limiting resistor 43 and the light-emitting unit 50.

Such a conventional light-emitting technology has been disclosed in TW Publication Nos. M320997, M32052l and M31738l and the like prior arts, however the electrical energy generated from the induction coil assembly may cause a discontinuous problem and large waveform oscillation, having an unstable illumination. Besides, the discontinuous electrical energy may decrease the service life of the light-emitting device.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

In accordance with one aspect of the present invention, there is provided a power-generating illumination device for a bicycle comprising at least one permanent magnet disposed onto rotatable wheel spokes so as to form a rotor; an induction coil assembly including two distribution lines extended therefrom and mounted onto a fork so as to form a stator, such that during the rotation of the rotor, the induction coil assembly may be cut by magnetic lines of force so that the distribution lines generate electrical energy; a control unit at least including a wave detector for connecting with one distribution line, a wave filter connected between the wave detector and another distribution line, a current limiting resistor coupled to the wave detector so as to parallelly connect with the wave filter, such that the wave detector, the wave filter and the current limiting resistor will form a loop; the wave detector may detect polarity of voltage of the generated electrical energy. and the wave filter may filter the generated electrical energy and lowering its resonating frequency; a LED unit coupled between the current limiting resistor and the wave filter for receiving the outputted electrical energy through the control unit.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in FIGS. 1-4, a power-generating illumination device for a bicycle in accordance with the present invention comprises at least one permanent magnet 20 disposed onto rotatable wheel spokes 11 so as to form a rotor; an induction coil assembly 30 including two distribution lines extended therefrom and mounted onto a fork 1 2 so as to form a stator, such that during the rotation of the rotor, the induction coil assembly 30 may be cut by magnetic lines of force so that the distribution lines generate electrical energy; a control unit 40 at least including a wave detector 41 for connecting with one distribution line, a wave filter 42 connected between the wave detector 41 and another distribution line, a current limiting resistor 43 coupled to the wave detector 41 so as to parallelly connect with the wave filter 42, such that the wave detector 41, the wave filter 42 and the current limiting resistor 43 will form a loop: the wave detector 41 may detect polarity of voltage of the generated electrical energy, and the wave filter 42 may filter the generated electrical energy and lowering its resonating frequency; a LED unit 50 coupled between the current limiting resistor 43 and the wave filter 42 for receiving the outputted electrical energy through the control unit 40, thereby obtaining an illuminating purpose.
Further referring to FIG. 4, during the rotation of the rotor, the power-generating illumination device of the present invention may act the induction coil assembly 30 to be cut by the magnetic lines of force for generating electrical energy, thus making a signal. Thereafter, the signal is detected, filtered and then inputted to the LED unit 50 through the current limiting resistor 43, thus stabilizing and filtering the waveform of the electrical energy. On the other hand, the discontinuous and oscillatory problem of the electrical energy may he effectively prevented, maintaining the brightness of the enabled LED unit 50 within a specific range. It is to he noted that the current limiting resistor 43 may be adjustable to control and maintain the brightness of the LED unit 50. Furthermore, in the enabling process of the stabilized electrical energy, the service life of the LED unit 50 and its related components may be maintained, thereby improving the stability of the power-generating illumination device.
As illustrated in FIG 5, in another embodiment of the present invention, the control unit 40 may include a flasher 44 affixed between the current limiting resistor 43 and the LED unit 50, thereby achieving a flash warning effect.
The invention is not limited to the above embodiment but various modifications thereof may be made. It will be understood by those skilled in the art that various changes in form and detail may made without departing from the scope and spirit of the present invention.
