In the present invention, when the illuminator 82 is directly disposed on the base 5 so that the excitation unit 7 is energized to cause excitation, the sensing unit 8 and the blade group 6 are relatively moved, and the sensing is performed. An electromotive force (emf) is generated in the element 82, and the inductive element 82 is electrically connected to the illuminator 83, so that the illuminator 83 is turned on and emits light. In addition to T, the heat dissipating fan can also have a luminescence when operating. In addition to the sense, it is more convenient to remove the steps of the conventional opening, which is much more convenient for the actual production of 9 1260964. Second, the light will not flash. Since the plurality of blades 62 are made of a light-transmitting material, and the illuminant 83 is disposed under the top cover 4, the light emitted by the illuminator 83 can be directly transmitted through the top cover 4 without being subjected to The plurality of blades 62 are rotated and cut 'so the light emitted does not flash, and does not make people feel uncomfortable. Third, save power. The present invention drives the plurality of blades 62 to rotate to form a gas convection by the turntable 61 to achieve the basic purpose of heat dissipation. At the same time, due to the relative movement of the induction power generating unit 8 and the blade group 6, an electromotive force (emf) is generated in the sensing component 82, and is electrically connected to the illuminator 83 by the sensing element μ, thereby generating The electromotive force is converted into a power source that supplies light to the illuminator 83. Therefore, the external heat dissipating fan of the present invention does not need to provide an additional power source to illuminate the illuminant 83. The outer pole type heat dissipating fan of the present invention utilizes the inductive element 82 to be opposite to the permanent surface ring 63 (3), so that the inductive element 82 generates a dynamic potential and is further supplied to the illuminant μ. Since the light is emitted, it is not necessary to additionally supply the power source for illuminating the illuminant 83, so that the external pole fan can generate a dazzling novel visual feeling due to the rotating illuminating, so that the purpose of the novel can be achieved. The above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto. The repairs are still within the scope of the patent of 10 1260964. 11 A26〇964 [Simple description]
