Abstract
A cooling fan includes a fan base, an impeller part, a driving part, an illumination circuit board and plural light-emitting elements. The driving part includes a shaft seat, a driving circuit board and plural coils. The driving circuit board is disposed on the fan base. The plural coils are arranged between the driving circuit board and the illumination circuit board and arranged around the shaft seat. The rotating shaft of the impeller part is inserted into the shaft seat. When an electric current flows through the plural coils, the rotating shaft is rotated. The plural light-emitting elements are disposed on the illumination circuit board. When the electric current flows through the plural light-emitting elements, the plural light-emitting elements emit light beams.
