New Description: [New Technology Field] This creation is about a cooling fan, especially a cooling fan that can display colorful light. [Prior Art] At present, the cooling fan is widely used in electronic devices to dissipate heat generated by the operation of the electronic device to ensure smooth operation of the electronic device. Since the cooling fan is installed in the casing of the electronic device, the design of the general cooling fan is usually designed toward the mechanical structure or the driving circuit. However, since the wind source must effectively dissipate the hot air inside the casing, it is usually disposed in the casing S. The side 'and the corresponding air outlet hole of the outer casing, so that the user of the electronic device can indeed see from the air outlet hole of the casing. In addition to the increasing emphasis on design of electronic devices, the cooling fan should be improved in terms of its design and drive circuit design. The use of the cooling fan should increase the overall value of the electronic device. [New content] In view of the above description, the main purpose of this creation is to provide a cooling fan that can display colorful light, so that the user can enjoy the dazzling effect of the variable color light while the fan is running. The main technical means for achieving the above purpose is to enable the displayable multi-color light-dissipating fan to include: a hollow frame ” is attached to a hollow bottom plate and is provided with a ring frame, and
I M345277 請配合參閱第五圖所示，係為該電路板上發光驅動電 路（21)係包含有： 一控制IC(211)，係包含有一輸入端（C1)及複數控制端 (E1/B2/C2)，其中複數控制端（E1/B2/C2)係對應連接複數多 彩發光元件的相同色光的晶片接腳，而輸出電壓予各色光 發光晶片； . 一穩壓電路，係由一穩壓IC(212)組成，該穩壓IC(212) - 輸入端連接一外部電壓（vcc)，將其處理穩壓後輸出一穩 • 定電壓（+5V)至該控制IC(211)的電源端；及 一開關（213)，係電連接至該控制iC(211)的輸入端 (C1)，觸發控制IC(211)重新依照色光順序控制不同色光晶 、片點亮，舉例來說控制1C設定顯示全彩、藍、綠、紅、 藍、綠、藍、紅、綠、紅、紅、綠、藍的順序。 由上述說明可知，電路板上的驅動電路驅動環框上的 多彩發光元件源呈現不同色光，相當炫麗；再者，由於發 光元件設置的貫穿孔係對應軸射方向，故複數等距設置‘ 參環框上的多彩發光元件發光時，即構成一轴射光形，啤應 、散熱風扇的扇葉轉子組，增添更美的炫耀光彩。 【圖式簡單說明】 第一圖：係本創作一較佳實施例的立體外觀圖。 第二圖：係第一圖的前視圖。 第三圖：係第一圖的部份前剖視圖 第四圖：係第一圖的背視圖。 7 M345277 第五圖：係本創作發光驅動電路的電路圖。 【主要元件符號說明】 (10)中空框架 (11)中間座板 (111)開口 (12)支條 (121)槽溝 (13)環框 (131)貫穿孔 (20)電路板 (21)發光驅動電路 (211)控制 1C (212)穩壓 1C (213)開關 (30)定子組 (31)扇葉轉子組 (40)多彩發光元件 (41)電線I M345277 Please refer to the fifth figure, which shows that the light-emitting drive circuit (21) on the circuit board includes: a control IC (211), which includes an input terminal (C1) and a complex control terminal (E1/B2). /C2), wherein the plurality of control terminals (E1/B2/C2) are corresponding to the chip pins of the same color light connecting the plurality of colorful light-emitting elements, and the output voltage is applied to the light-emitting chips of the respective colors; The IC (212) is composed of an external voltage (vcc) connected to the input terminal of the voltage regulator IC (212), and is regulated to output a constant voltage (+5V) to the power supply end of the control IC (211). And a switch (213) electrically connected to the input end (C1) of the control iC (211), and the trigger control IC (211) re-controls the different color crystals and the chip lighting according to the color light sequence, for example, controlling the 1C setting Displays the order of full color, blue, green, red, blue, green, blue, red, green, red, red, green, and blue. It can be seen from the above description that the source of the colorful light-emitting elements on the driving circuit of the driving circuit on the circuit board exhibits different color lights, which is quite dazzling; furthermore, since the through-holes provided by the light-emitting elements correspond to the axial direction, the plural isometric setting When the colorful light-emitting elements on the ring frame emit light, they form a shaft-shaped light shape, and the fan-rotor group of the beer and the cooling fan adds a more beautiful brilliance.
