Abstract
A luminous fan includes a supporting mechanism, a main circuit board, a light-guiding impeller and an illumination module. The light-guiding impeller is pivotally coupled to a bracket of the supporting mechanism. The illumination module is disposed within a hub of the light-guiding impeller. After a light beam from a light-emitting element of the illumination module is emitted to a lens assembly, the light beam is refracted by a secondary lens of the lens assembly and transmitted to the light-guiding impeller. Consequently, the light-guiding impeller is illuminated.
