     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present disclosure will become clearer in light of the following detailed description of an illustrative embodiment of this disclosure described in connection with the drawings, so that people having ordinary skill in the art can implement the present disclosure according to the description of this specification. 
     With reference to  FIGS. 1 and 2  for a ring-shaped light fan of this disclosure, the ring-shaped light fan comprises a frame  1  and a first receiving chamber  11  disposed at the frame  1 , and the first receiving chamber  11  contains a first fan  21 , and each end point of the frame  1  has a fixing hole  13 , and the frame  1 , the fixing hole  13  and the first receiving chamber  11  are integrally formed, and the outer periphery of the frame  1  has a light emitting module  3 . 
     The ring-shaped light fan of this embodiment has the following effects: 
     The fan can emit a ring-shaped light. In the ring-shaped light fan of this embodiment, four fixing holes  13  are integrated on the frame  1 , and the light emitting module  3  is mounted around the periphery of the frame  1 , so that the frame  1  can be fixed to a cooling system of a standard size without blocking the light emitted from the light emitting module  3 . With a reasonable design, the ring-shaped light fan of this embodiment can avoid the light of the light strip from being blocked by the fixing hole  13 , so as to achieve the ring-shaped lighting effect of the fan. 
     Specifically, the light emitting module  3  comprises an LED lamp strip  31  and a lampshade  32 , and the outer periphery of the frame  1  has a groove  33 , and the LED lamp strip  31  is received and installed in the groove  33 , and the lampshade  32  is covered onto the groove  33 . The LED lamp strip  31  is embedded into the groove  33 , and the lampshade  32  covers the groove  33  for protecting the LED lamp strip  31 . In the meantime, the light emitted from the LED lamp strip  31  can be transmitted to the outside of the fan through the lampshade  32 . In this embodiment, the light emitting module  3  is mounted around the frame  1 , and the LED lamp strip  31  shows a whole circle of light without having any gap occurred in the light. In this embodiment, the lampshade  32  extends upwardly from the interior of the frame  1  and further extends along a parallel direction and has a portion exposed from the frame  1 , so that the light emitted from the LED lamp strip  31  can pass through the lampshade  32 , and the light is emitted from both upper and middle rings of the frame  1 . In the meantime, the lampshade  32  is made of a fully transparent material or a matte material to achieve different lighting and displaying effects. 
     In addition, a sealant is disposed between the lampshade  32  and the frame  1 . Since a large quantity of dust may be accumulated in the housing of the cooling system after a long time of use, the aforementioned arrangement can improve the sealing effect of the LED lamp strip  31  in the groove  33  and can prevent the dust from entering into the groove  33  which will affect the displaying effect of the LED lamp strip  31 . 
     In general, the size of a single cooling fan is 120 mm or 140 mm. A larger volume of vanes gives rise to a larger energy consumption used for the heat dissipation. The cooling system is generally a form of a cuboid to facilitate its installation in the housing of the main system. In this embodiment, when the frame  1  has just one first receiving chamber  11  and the size of the frame  1  is 120 mm or 140 mm, the ring-shaped light fan may be mounted onto a cooling system having a size of 120 mm or 140 mm. 
     Specifically, the ring-shaped light fan further comprises a second receiving chamber  12  and a second fan  22 , and the second fan  22  is received and installed in the second receiving chamber  12 , and the first receiving chamber  11  and the second receiving chamber  12  are disposed at both ends of the frame  1  respectively, and the frame  1 , the first receiving chamber  11  and the second receiving chamber  12  are integrally formed. In this embodiment, the first receiving chamber  11  and the second receiving chamber  12  are respectively and symmetrically disposed on both sides of the frame  1 . In the meantime, the frame  1  is a square structure, and the fixing holes  13  are disposed at four vertices of the frame  1  respectively. In this embodiment, after the ring-shaped light fan and the cooling system are installed, the assembled fan has a good overall appearance and the fan and the cooling system can have a better combination effect. 
     The ring-shaped light fan of this embodiment can also be used in a cooling system having the size of 240 mm or 280 mm. It is noteworthy that there are cooling systems having three or more cooling fans, and the size of the cooling system having three cooling fans is 360 mm and 420 mm. Therefore, this embodiment may further comprise a third receiving chamber and a third fan, wherein the third fan is received and installed in the third receiving chamber, and the third receiving chamber is disposed at the frame, and the first receiving chamber  11 , the second receiving chamber  12  and the third receiving chamber are integrally formed with the frame  1 . Therefore, three fans used for cooling can be fitted into the frame of the size of 360 mm or 420 mm, and the ring-shaped light fan of this embodiment can be mounted onto the cooling system of the size of 360 mm or 420 mm, so as to meet the higher requirements for heat dissipation and power consumption. 
     Specifically, the third fan is installed between the first fan  21  and the second fan  22  on the frame  1 , and the first fan  21  and the second fan  22  with respect to the third fan are respectively and symmetrically disposed at both ends of the frame  1 , so that the fan has a good overall appearance as well as a uniform cooling effect of the cooling system.
