ABSTRACT:
An illuminative fan includes a plurality of illuminators selected from light-emitting diodes juxtapositionally interlacedly disposed on each fan blade capable of being flashed or colored so that upon a rotation of the fan, the illuminators will produce diversified optical or colorful figures on the rotating blades due to persistence of human vision either flashingly or continuously for enriching a decorative effect for the illuminative fan.
