     DESCRIPTION OF THE EMBODIMENTS 
       FIG. 1  is a schematic diagram illustrating an electronic device according to an embodiment of the present invention. Referring to  FIG. 1 , the electronic device  100  of the present embodiment includes a frame  110 , a fan  120  and at least one light emitting component  130 .

     The frame  110  includes a plurality of self-induction power supply coils  112 , a self-induction power supply coil base  113 , a magnet  114 , a magnet base  115 , a bracket shell  116  and a rotation bearing  118 . The magnet base  115  is disposed in the bracket shell  116 . The self-induction power supply coils  112  are disposed in the self-induction power supply coil base  113 , and the self-induction power supply coil base  113  is disposed between the bracket shell  116  and the fan  120 . The rotation bearing  118  penetrates through the bracket shell  116 , the magnet base  115 , a circuit substrate  150  and the fan  120 . The fan  120  can drive the self-induction power supply coil base  113  to rotate along the rotation bearing  118 , so as to rotate the self-induction power supply coils  112 , so that the self-induction power supply coils  112  can be rotated relative to the magnet  114  to generate an induction current. The induction current is guided to a self-induction power supply coil pin socket  152  through a self-induction power supply coil pin  112   a,  so as to provide current required by the circuit substrate  150 . 
     Moreover, the frame  110  further includes a plurality of assembling screws  117 , and the assembling screws  117  penetrate through the self-induction power supply coil base  113  and the circuit substrate  150  to assemble the fan  120 , the self-induction power supply coil base  113  and the circuit substrate  150 . In addition, the frame  110  further includes a fairing  119 , and the fan  120  is disposed between the fairing  119  and the bracket shell  116 . Moreover, the light emitting component  130  includes a light emitter  132  and a data control flat cable  134 , and the light emitter  132  and the data control flat cable  134  are integrated and connected. The light emitting component  130  of the present embodiment can be an organic light emitting diode (LED), an inorganic LED, a cold cathode fluorescent lamp (CCFL) or combinations thereof. 
     The electronic device  100  further includes the circuit substrate  150  disposed between the fan  120  and the self-induction power supply coils  112 , wherein the self-induction power supply coils  112  are electrically connected to the circuit substrate  150 .  FIG. 2A  is an enlarged diagram of the circuit substrate, and  FIG. 2B  is a partial enlarged diagram of the self-induction power supply coil base. Referring to  FIG. 2A  and  FIG. 2B , the circuit substrate  150  has the self-induction power supply coil pin socket  152 , and the self-induction power supply coils  112  have the self-induction power supply coil pin  112   a.  The self-induction power supply coil pin  112   a  is correspondingly inserted into the self-induction power supply coil pin socket  152  for electrical connection. Moreover, the circuit substrate  150  further has a control chip  154 , and the control chip  154  is electrically connected to the light emitter  132  of the light emitting component  130  through the data control flat cable  134  inserted in a data control flat cable socket  170 , so that the control chip  154  can control light emitting and image displaying of the organic LED  130 . Moreover, the circuit substrate  150  has a plurality of the data control flat cable sockets  170 , which are used for electrically connecting the light emitting components  130  and the circuit substrate  150 . 
     Referring to  FIG. 1  and  FIG. 2A , the light emitting components  130  and the blades  122  of the fan  120  can be formed integrally, wherein the blades  122  are hollowed blades, so that the light emitting components  130  can be fit or installed on the blades  122 . Alternatively, the light emitting components  130  can also be attached or assembled on the blades  122  according to an actual design requirement. Materials of the blades  122  can be transparent materials, so that the light emitted by the light emitting components  130  is not shielded and is transmitted through the blades  122 . Certainly, a fog treatment can also be performed to the blades  122  according to an actual demand, so that when the light emitting components  130  emit light, a light emitting pattern of the electronic device  100  can be more splendid and changeful. Moreover, a shape of the light emitting component  130  can be designed according to an actual demand. 
     In detail, when the blades  122  of the fan  120  are rotated along the rotation bearing  118  due to disturbance of wind or water, the electronic device  100  starts to operate, and rotation of the fan  120  results in an electromagnetic conversion between the self-induction power supply coils  112  and the magnet  114  to generate electric power. The electronic device  100  can be further connected to a power storage device (not shown), so that the electric power generated due to the rotation of the fan  120  is transmitted from the self-induction power supply coil pin  112   a  of the self-induction power supply coils  112  to the power storage device (not shown), and stored therein through the self-induction power supply coil pin socket  152 . It should be noticed that since the light emitting components  130  are flexible, the light emitting components  130  can be easily fitted to different kinds of the blades  122 . The blades  122  can be hydrodynamic waterwheel blades or aerodynamic fan blades, or the light emitting components  130  and the hydrodynamic waterwheel blades or the aerodynamic fan blades can be formed integrally. While the hydrodynamic waterwheel blades or the aerodynamic fan blades are rotated to generate electric power through the natural water or wind power to achieve an energy saving and a carbon reduction effects, the light emitting components  130  can emit light, so that the electronic device  100  can simultaneously have a lighting function. 
     Moreover, the control chip  154  can have in-built control programs for controlling light emitting and image displaying of the light emitting components  130  when the blades  122  of the fan  120  are rotated, so that the electronic device  100  can achieve a large area lighting and image displaying effect or a rotation lighting and image displaying effect, and color variation thereof can be further controlled. Therefore, the electronic device  100  can not only use the natural wind power or water power to generate electric power to achieve the energy saving and the carbon reduction effects, but can also achieve aesthetic lighting and image displaying effects, so that variability and interestingness of the electronic device  100  during the lighting and image displaying are increased. 
     In the present embodiment, although the light emitting components  130  are assumed to be disposed on the blades  122 , configuration positions of the light emitting components  130  can also be varied according to a design requirement, for example, the light emitting components  130  are disposed on the bracket shell  116  or the fairing  119 . Moreover, the electronic device  100  is not limited to the implementation type of  FIG. 1 , which can also be a wind power generator, a water-driven waterwheel (shown in  FIG. 3A ), a general wind-driven windmill (shown in  FIG. 3B ), an electric fan, propeller spiral blades of an aircraft, a ship or a helicopter, a hand fan, a ventilator, a general handheld windmill (shown in  FIG. 3C ), a vertical axis fan (shown in  FIG. 3D ) or a cooling fan of a computer, etc. In various implementations of the electronic device  100  shown in  FIGS. 3A-3D , referential numerals of the aforementioned blade  122  and the light emitting component  130  are used. In addition, the light emitting components  130  can also be implemented by other types of light sources, such as LEDs, or combinations of the other types of light sources according to an actual requirement. 
     It should be noticed that in the above embodiment, although the light emitting components  130  are taken as an example, the light emitting components  130  can also be replaced by light guiding components, and the purpose of the present invention can also be achieved.  FIG. 4A  is a schematic diagram illustrating an electronic device according to another embodiment of the present invention, and  FIG. 4B  is an enlarged diagram of a circuit substrate of  FIG. 4A . Referring to  FIG. 4A  and  FIG. 4B , a difference there between is that light guiding components  130 ′ are used to replace the light emitting components  130 , and light sources  156  (seven light sources  156  are illustrated in  FIG. 4B ) are disposed on the circuit substrate  150 ′. The light sources  156  are electrically connected to the control chip  154 , and the light guiding components  130 ′ are disposed aside the light sources  156 . Each of the light guiding components  130 ′ may have two parts  130   a  and  130   b,  and the light guiding components  130 ′ can guide the light emitted from the light sources  156  to achieve a light emitting effect. The light guiding components  130 ′ can be fibers or other types of light guiding substances according to an actual demand. Moreover, although the light guiding component  130 ′ is divided into two parts  130   a  and  130   b  due to an assembling requirement, it can also be divided into a plurality of parts according to an actual demand, or the light guiding component  130 ′ can be only one fiber, and the fiber penetrates through a frame of the fan  120  and is assembled with the blade  122 . 
     In summary, in the present invention, the light emitting components or the light guiding components are, for example, disposed on the hydrodynamic waterwheel blades or the aerodynamic fan blades, so that electric power can be generated or stored when the electronic device is operated, so as to achieve the energy saving and carbon reduction effects. Meanwhile, the electronic device also has a lighting function and the light emitting and image displaying functions, so as to increase interestingness of lighting in the night. Moreover, since the light emitting components or the light guiding components can replace a part of the blade materials, a material cost of the electronic device can be saved. In addition, since the electronic device can emit light by itself, a cost for additionally configuring a lighting equipment around the electronic device can be saved. 
     It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
