Each of the two bases has a first through hole and a second through hole, and an extending length direction of the first through hole and an extending direction of the second through hole are staggered relative to the surrounding side surface.

A light-emitting fan includes a fan frame, an impeller, a circuit board and a light-emitting component. The impeller includes a light guiding hub and a plurality of blades. The light guiding hub is disposed on the fan frame. The light guiding hub has an outer top surface, an outer annular surface, an inner annular surface, and a recess. The outer annular surface is connected to the outer top surface, the inner annular surface faces away from the outer annular surface. The blades are connected to the outer annular surface. The recess is located at the inner annular surface so as to form a light guiding protrusion of the light guiding hub. The circuit board is disposed on the fan frame. The light-emitting component is disposed on the circuit board. Light generated by the light-emitting component is emitted from the outer top surface through the light guiding protrusion.

A concealed office fan lamp is provided, which includes a stop device, a support and a fan blade. A lamp is arranged at the bottom of the support, a cavity is arranged in the support, the fan blade is electrically connected with a driving mechanism to make it rotatably arranged in the cavity, and the stop device is arranged on the support and/or the fan blade to detect the motion state of the fan blade. According to the motion state, the fan blade is stopped and hidden in the cavity. By providing a stop device on the fan lamp, the fan blade can be accurately stopped and hidden in the cavity, the person under the fan lamp cannot see the fan blade when the fan lamp stops working, making the fan lamp more beautiful as a whole.

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.

Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include one or more UV-C light sources which irradiate contaminants as air flows through the UV-C unit.
