A compact conditioning system for controlling a volume, comprises: (a) at least one light source, said light source being coupled with a replaceable focusing lens; (b) at least one fan; (c) at least one temperature sensor; (d) control circuitry adapted to receive inputs from said sensor(s) and/or from a user, and to operate said light source(s) and/or said fan(s) as a result thereof; and (e) a housing suitable to house said light source, fan and control circuitry and adapted to be positioned at the top of a structural element defining a closed space.

An integrated ceiling device includes a housing retaining an electronic assembly, a heat sink having a central opening, a light source coupled onto the heat sink, the housing is coupled with and disposed at least partly above the heat sink, and a central vertical axis of the housing aligns or is in proximity with the central opening of the heat sink.

A ceiling fan and a surrounding device thereof are provided. The ceiling fan includes a main body, a bracket set connected to the main body, and a surrounding device connected to the bracket set. The main body includes a main shaft, a motor, and a plurality of ceiling fan blades. The bracket set includes a plurality of brackets, and each of the brackets has one end connected to the main shaft. The surrounding device is connected to another end of each of the brackets that is relatively far away from the main shaft, and the surrounding device is roundly arranged around and spaced apart from an end of each of the ceiling fan blades that is relatively far away from the motor. The surrounding device includes at least one functional component that is configured to disinfect or sterilize air or to provide lighting.

An integral fan blade includes a fan blade connecting disk and a plurality of fan blade bodies arranged around and equidistantly surrounding the fan blade connecting disk. The fan blade bodies and the fan blade connecting disk are integrally formed. This design allows the wind angle to cover a cone-shaped area from top to bottom. Under the same specifications, the wind force is relatively larger than ordinary conventional fan blades, and the coverage area is also larger, thus bringing better blowing effect and better use effect to users.

A lighting apparatus includes a fan device, a driver, a connector and a light module. The lighting apparatus is installing to a cavity of a ceiling. The fan device has a fan and an air channel. The fan is placed in the cavity. The driver converts an external power source to a first driving current supplied to the fan device. The connector is fixed to the fan device. The first light source receives a second driving current provided by the driver. The air channel has an entrance between the main housing and the fan device. The entrance is visually concealed by the main housing when a viewer stands below the lighting apparatus.

A ceiling fan blade cover is provided. The device includes a flexible body and a lighting element. The flexible body includes a closed end and an open end. The open end defines an opening. The flexible body is designed to cover an individual ceiling fan blade. An attaching member is disposed on the flexible body. A fastener encircles the opening. The fastener secures the ceiling fan blade cover to the ceiling fan blade. In one embodiment, the fastener is an elastic band. In another embodiment, the fastener is an adjustable string with a slidable toggle. The lighting element includes a securing member that connects to the attaching member. The securing member secures the lighting element to the flexible body. The lighting element includes a transceiver which is operably connected to a controller. The controller may alter the color, pulsation, and intensity of illumination from the lighting element.

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. The UV-C unit is mounted on either a universal mounting mechanism or a mobile support unit to provide mobility to the UV-C unit.

A fan light has a fan assembly, a connecting assembly, and a lighting disc assembly. The fan assembly has a motor case, a main shaft, and multiple fan blades. The connecting assembly has a connecting unit main body having a main shaft connecting screw hole and multiple lighting disc fixing holes, a screw fixing hole formed on an inner surface of the main shaft connecting screw hole, and a fixing unit. The main shaft is mounted in the main shaft connecting screw hole. The fixing unit is mounted in the screw fixing hole to fix the main shaft. The lighting disc assembly has a lighting disc fixing shell having multiple lighting disc mounting holes. The lighting disc fixing shell is fixed on the top surface of the connecting unit main body via the lighting disc mounting holes and the lighting disc fixing holes.

A load control device may control power delivered from a power source, such as an alternating-current (AC) power source, to at least two electrical loads, such as a lighting load and a motor load. The load control device may include multiple load control circuit, such as a dimmer circuit and a motor drive circuit, for controlling the power delivered to the lighting load and the motor load, respectively. The load control device may adjust the rotational speed of the motor load in a manner so as to minimize acoustic noise generated by the load control device and reduce the amount of time required to adjust the rotational speed of the motor load. The load control device may remain powered when one of the electrical loads (e.g., the lighting load) has been removed (e.g., electrically disconnected or uninstalled) and/or has failed in an open state (has “burnt out” or “blown out”).

A LED light with built-in Air flow device has AC-to-DC circuit to get DC current to supply power to LED or LEDs and-to charge inside rechargeable batteries and to the inside air flow related device or other product(s). The LED light connect IC and control circuit to make setting, changing, adjust of the said at least one of (A) LED(s) colors, brightness, on-off, duration, cycles, frequency, sequential, flashing, color changing, color selection, auto changing, or other LED light effects, (B) Air flow related parts to get desired speed of rotating fan or blade, on-off, duration, timer, countdown timer, or other desired air flow related function(s); by at least one of (1) trigger system, (2) switch, (3) sensor, (4) motion or moving or radar sensor, (5) IR or RF remote control system, (6) power fail sensor, (7) built-in Auto-Off-On or multiple selection positions switch, (8) other related LED or air flow or air-freshener or fragrance or essential oil diffusor parts or accessories; wherein the LED light connect with (i) AC power source by prongs with or without folding features, (ii) DC power from at least one outside transformer, power bank, DC power from cigarette-plug, USB related DC power source, DC power storage device, solar module, or DC generator.
