Brightness; in short, when the cooling fan i is energized, the brightness of the light-emitting diode 24 is low, so that the overall glare effect can be poor. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a self-illuminating heat-dissipating fan which has high luminance and excellent glare effect. Thus, the self-illuminating heat dissipating fan of the present invention comprises a frame unit, a driving unit, a fan unit, a lighting unit, at least a second stator, an insulating ring, and a second magnet ring. The frame unit has a base and a shaft tube disposed on the base.

And the two do not interfere with each other. The second magnet ring 36 is fixedly disposed at a position that can interact with the induction coil 352 to generate a magnetic interaction change. In this embodiment, the second magnet ring 36 is sleeved on the frame unit 31. The extending portion 317 i ' of the shaft tube M2 and the structure of the extending portion 317 can be configured to be separated from the first stator 321 of the driving unit 32 after the second magnet ring 36 is sleeved and fixed, thereby The second magnet ring 36 and the first stator 321 do not interfere with each other. After the first circuit board 322 is energized by the external power source, the first stator 321 can be electrically conductive to generate an alternating magnetic field, and the magnetic force of the first magnet ring 334 is repelled to generate rotation. The hub 332 and the blade 333 The stator frame 351 of the second stator 35 and the induction coil 352 also rotate synchronously. As for the self-luminous technology of the present embodiment, the second stator 35 is continuously rotated by the stator frame 351 around the stationary second magnet ring 36 to generate a back electromotive force, and then wound by The induction coil 352 on the stator frame 351 generates a current and transmits the current to the second circuit board 341, so that the light-emitting element 342 electrically connected to the second circuit board 341 can be electrically conductive and emit light at 9 200936021. An advantage of the present invention is that the second stator 35 can be disposed on the inner side of the wheel 332 of the fan unit 33 and utilize the first stator 321 so as not to go too far inside the hub 332. A large portion of the space inside the hub 332 enables the second stator 35 to have a larger stator frame 351 and winds a larger number of induction coils 352, and the number of the second stators 35 can also be increased, and thus the fan When the wheel unit 33 rotates, it can cooperate to generate more electric energy. In summary, the self-illuminating heat dissipating fan 3 of the present invention is fixed to the inner side of the hub 332 by the stator frame 351 of the second stator 35, and effectively utilizes the space of the inner side of the stern wheel 3 3 2 The volume of the stator frame 315 can be effectively enlarged, so that the number of the induction coils 352 wound on the stator frame 351 is increased, and when the heat dissipation fan 3 is energized, the induction coil 352 will be larger. The electric energy is transmitted to the second circuit board 341 and the light-emitting element 342 to increase the brightness of the light-emitting element 342, resulting in a more excellent glare effect, so that the object of the present invention can be achieved. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All remain within the scope of the invention patent.
