When thefan blade 35 starts to rotate, light generated from theoptic fiber 36 is guided and emitted via the light guiding means 352 of thefan blade 35.Cover portions 3225 are disposed outside of where thefan blade 35 is connected to thefan stand 3221, so as to prevent light from scattering into needless directions, elevate the contrasting effects of light, and enhance the intensity of the emitted light. Moreover, the light generator (not shown) is preferably disposed in thestationary portion 321 of thehousing 32, but the light generator (not shown) may also be disposed at an external side of theceiling fan 3 if only one light generator (not shown) is used to provide light for theoptic fibers 36 ofmultiple ceiling fans 3, or if it is desirable to prevent the light generator (not shown) from instability due to the operation of theceiling fan 3. The light guiding means 352 of thefan blade 35 further comprise afirst configuration 351, so as to make the light guided via thefan blade 35 appear dynamically during the operation of theceiling fan 3. Thefirst configuration 351 is a plurality of arc-shaped structures which may be a protruding rib, a groove, or a combination thereof distributed on an upper side of thefan blade 35; The arc-shaped structures are preferably centered on an axis of theswivel portion 322. Thestationary portion 321 may further comprise a plurality ofupper lighting elements 361 on an upper side of thefan blade 35, and a plurality oflower lighting elements 362 on a lower side of thefan blade 35. Theupper lighting element 361 and thelower lighting element 362 may be optic fibers, LEDs, light bulbs, or a combination thereof. The LED may be a red-light LED, a green-light LED, a blue-light LED, a white-light LED, or a combination thereof. An external side of theupper lighting element 361 may further include an uppertranslucent cover 326, and an external side of thelower lighting element 362 may further include a lowertranslucent cover 327, so that light may be passed through theupper lighting element 361 and thelower lighting element 362. - The combinational design of a
stator 323 and arotor 324 can be divided into two types, inner rotor design and outer rotor design. In the combinational design in which inner rotor design is adopted, therotor 324 is located inside thestator 323, and thestator 323 remains stationary while therotor 324 is connected to a spinning axis during operation. In the combinational design in which outer rotor design is adopted, therotor 324 is located outside thestator 323, and thestator 323 remains stationary while therotor 324 rotates about astationary axis 3231 during operation.
