An annular air inlet is formed between the hub 22 and the cover plate 14.
The light-emitting element 3 is arranged in the vertical projection area of the air inlet and the cover plate 14 on the bottom plate 11. The light emitting element 3 has a light projection region covering at least a portion of the air inlet such that light emitted from the light emitting element 3 can be emitted through at least a portion of the air inlet. The light projection region covers at least a part of the fan blade 23, and at least a part of the fan blade 23 is located on a path through which light emitted from the light emitting element 3 is emitted through the air inlet. The light projecting region covers at least a part of the light-transmitting portion 222 so that light emitted from the light-emitting element 3 can pass through the light-transmitting portion 222 and exit through the air inlet.
The light emitting element 3 may be disposed on the bottom plate 11 at a position corresponding to the light-transmitting portion 222, so that light emitted from the light emitting element 3 may be emitted to the outside of the fan frame 1 through the light-transmitting portion 222. Preferably, the perpendicular projection of the light emitting element 3 on the fan wheel 2 is located on the light-transmitting portion 222, so that a desired lighting effect can be achieved at the position of the hub 22 of the fan wheel 2.
In a specific application, the light emitting element 3 may be disposed at an edge of the first surface of the circuit board 13, and the light emitting element 3 is driven to be turned on or off, or to be switched in color by a driving circuit or the like correspondingly disposed on the circuit board 13.
