Abstract: A ceiling fan and a fan set are provided. The fan set includes an upper fixed plate, a lower fixed plate, and a plurality of fan blades. The upper fixed plate has a plurality of first through holes that are in a ring-shaped arrangement, and the lower fixed plate has a plurality of second through holes that are in a ring-shaped arrangement. The quantity of the second through holes is equal to the quantity of the first through holes, and the positions of the second through holes respectively correspond to the positions of the first through hole. Each of the fan blades has an assembly portion, a blade portion, and three fasteners. The fasteners pass through the first through holes and the second through holes such that each of the fan blades is fastened between the upper fixed plate and the lower fixed plate.

Abstract: A ceiling fan includes a fan body, a sensing unit and a control unit. The fan body includes a base seat, a plurality of fan blades mounted to the base seat, and a motor mounted to the base seat for driving rotation of the fan blades about the base seat. The sensing unit includes an outer casing, a room temperature sensor, and a body temperature sensor. The control unit is mounted to the fan body, in communication with the room temperature sensor, the body temperature sensor and the motor, and operable to adjust a rotational speed of the fan blades by controlling the motor according to a room temperature and a body temperature respectively sensed by the room temperature sensor and the body temperature sensor.

Abstract: A ceiling fan includes a transmission unit for decoration. The transmission unit includes a base seat connected to a stator axle of a rotating motor for driving a blade module, a sun gear disposed rotatably on the base seat, a driving motor disposed on the base seat, and a first planet gear connected to the driving motor and meshing with the sun gear. The driving motor drives the first planet gear to rotate the sun gear. The sun and first planet gears are exposed at a bottom side of the base seat so as to be externally visible.
