Abstract: A fan includes a motor, a plurality of fan blades coupled to the motor and rotatable by the motor, a light source positioned to be independent from rotation of the plurality of fan blades, and a processor controlling the first light source to turn on/off with a frequency determined at least based on a relation with respect to a rotational speed of the plurality of fan blades. Thereby, a visually static view or a slowly rotating view of the fan blades is displayed while the fan blades are operating.
