Ceiling fan having an electric lamp which has continuous color temperature control. A ceiling fan includes an electric motor which rotates blades; and an electric lamp, which is an integrated component of the ceiling fan and is co-located beneath the blades. The motor and the lamp receive electric power from a mains electric socket via a single electric power cord that provides Alternating Current. The lamp is configured to emit visible light having light warmth at a user-configurable level along a continuous spectrum of light warmth, between a lower-bound value and an upper-bound value. The electric lamp includes a first set of LEDs and a second set of LEDs. The first set of LEDs is capable of emitting visible light at a first, fixed, light warmth value, which is the lower-bound value of that continuous spectrum of light warmth levels. The second set of LEDs is capable of emitting visible light at a second, fixed, light warmth value, which is the upper-bound value of that continuous spectrum of light warmth levels.

A color temperature and brightness control system for an LED lamp of a ceiling fan includes a switch, a detection module, a determining module, a memory module, a control module, and a drive unit. The detection module detects the actuation of the switch, and the determining module performs a comparison. The control module outputs a control signal to the drive unit according to the calculation result of the determining module and the memory module to drive the lamp to actuate. The color temperature and brightness control system is able to control the lamp to be turned on/off and the brightness and color temperature of the lamp through a single switch.

A singular passive/active ventilation and lighting apparatus for enclosed spaces. The apparatus is adapted to harness solar energy through a cover which also directs light down through a reflective tube. The apparatus provides a passive vent which is fluidly coupled to the same reflective tube. As the reflective tube couples the external environment with an enclosed space, passive/active ventilation and passive/active light is directed to the enclosed space. The solar energy is directed to other components supported by the singular apparatus, like the active lighting and active ventilation fan as well as a wireless router, an electric charger and power storage unit for storing the harnessed solar energy and powering the active components.

A ceiling fan with a ceiling projection function includes a ceiling fan body and a ceiling fan housing. The ceiling fan body includes a plurality of blades, a motor that drives the blades to rotate, and a hanging rod. The ceiling fan housing is provided with a pattern hole unit and a light-emitting unit. The pattern hole unit has at least one pattern hole. The pattern hole of the pattern hole unit passes through the ceiling fan housing. The light-emitting unit has at least one light-emitting member. When in use, the light-emitting member of the light-emitting unit projects a light beam passing through the pattern hole of the pattern hole unit to project a pattern of the pattern hole of the pattern hole unit outside the ceiling fan housing and above the blades.

A temperature destratification assembly can include an outer housing. An impeller can be positioned within the outer housing between the inlet and outlet of the outer housing. The impeller can have an impeller hub and a plurality of impeller blades extending radially outward from the impeller hub. The assembly can include an impeller motor configured to rotate the impeller blades about an axis of rotation. A stator can be positioned within the outer housing between the impeller and the outlet of the outer housing. The stator can include a plurality of vanes. The stator vanes can include an upstream edge at the upstream end of the stator, a first surface extending from the upstream edge to the downstream edge of the vane, and a second surface opposite the first surface and extending from the upstream edge to the downstream edge of vane. A plurality of the vanes can have a downstream edge at the outlet of the outer housing.

A lamp installation structure of a ceiling fan has a first base connected to a fixing seat of the ceiling fan and a second base connected to a lamp. The first base is provided with a plurality of positioning members. The second base has grooves and guide rails corresponding to the positioning members for insertion of the positioning members. The guide rails are provided with a plurality of elastic members to elastically press against the positioning members. Thereby, through the positioning members being retained to the guide rails, the lamp installation structure of the ceiling fan has the advantages of quick installation and increased stability of the ceiling fan.

A quick connect mounting assembly for a ceiling fan. The quick connect mounting assembly includes two releasably attachable plates that are easily interconnected to mechanically couple elements of a ceiling fan. The quick connect mounting assembly can be used to mount a ceiling fan switch housing to a ceiling fan motor assembly.
