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 fixture system includes a housing configured to be mounted in an upper region of a room or area. A light source is supported by the housing for providing visible light to illuminate at least a portion of the room or area. An ultraviolet radiation (UVR) system is supported by the housing for emitting UVC radiation in an upper region of the room or area. The UVR system includes at least one UVC emitting source and an optic member configured to direct UVC radiation in a pattern having a vertical width dimension that is above a threshold height from a floor or ground in the room or area.

A combined ventilation and illumination system includes a ventilation assembly, a light fixture assembly, and a connector assembly. In an installed position, the system is installed above a ceiling of a room of building structure (e.g., a residence or workplace) to provide ventilation for the room. The system couples a light fixture to ventilation assembly below the ceiling. In the installed position, an air flow cavity is defined between the light fixture and the ceiling, where the cavity allows for air flow around the light fixture and into the ventilation assembly for eventual exhaust beyond the room in which the system is installed. The cavity includes a first critical distance that is sized according to operating parameters of a blower of the ventilation assembly to provide an adequate flow rate of intake air and to provide acceptable sound levels during operation of the system.

A joint assembly for luminaires is provided. The joint assembly includes a pin having at least one pin section with an upper opening, a side opening, and a bore connecting the upper opening and the side opening. The upper opening is configured to receive at least one power cable to feed through the bore and out the side opening. The joint assembly also includes a primary hinge having a primary vertical base and a plurality of primary knuckles extending from the vertical base, wherein a distal portion of the knuckles has a hole for engaging the pin. The joint assembly also includes at least one secondary hinge having a secondary vertical base and a plurality of secondary knuckles extending from the vertical base, wherein a distal portion of the knuckles has a hole for engaging the pin.

Mounting boxes for overhead beams, such as purlins, of a building are described. The mounting box may include a front side that is designed to attach to a lateral side of the beam, an upper portion bottom that may rest on the horizontal beam, and a lower portion bottom that may have or be connected to a lighting socket or other electrical device.

A light fixture includes a housing, and a lighting module. The housing defines first and second portions. The second portion defines a window. The lighting module is at least partially disposed in the second portion. The lighting module includes a submount, a plurality of light emitting diodes, a lens cover, and an encapsulating material. The plurality of light emitting diodes is coupled with the submount and is configured to project light through the window. The lens cover includes an exterior surface and overlies the plurality of light emitting diodes and the submount such that the lens cover and the submount define an interior therebetween. The encapsulating material substantially fills the interior.

An electrical connector strip is adapted for structural applications in theater, television and entertainment industries. The connector strip includes a rigid tubular enclosure defining a hollow continuous internal wireway receiving electrical wiring within an inside diameter of the enclosure, and having a substantially uniform outside diameter between opposite ends of the enclosure. At least one outlet pocket is formed in a side wall of the enclosure. A connector adapter plate is located in the outlet pocket, and extends within the inside diameter of the enclosure. At least one output connector is carried by the connector adapter plate, and resides within the inside diameter of the enclosure with external access provided through the outlet pocket.

Luminaire (1) comprising suspension means (3) and a housing (5) with a top wall (7). Said suspension means (3) comprising a hook (9a, b) formed of an elastic wire (11) with a loop portion (15) connected to two remote, oppositely arranged end portions (13a, b) each forming a spindle (17a, b), and two elongated channel elements (19a, b) arranged along a rotation axis (21) and mounted on the top wall (7), with each spindle (17a, b) being snugly fitted in a respective channel element (19a, b). By a mutual misalignment between the spindles (17a, b) and the channel element (19a, b) with respect to the rotation axis (21), the hook (9a, b) is in a low tension state when in a first rotational position (27), and in a high tension state when in further rotational positions (29) and urging the hook (9a, b) to assume the first rotational position (27).

A system for configuring an environment to provide mobile computing, the system including: one or more booms suspended from a soffit of the environment, each of the booms including a moveable arm moveable at least in part in a plane parallel to the soffit and the moveable arm having a proximal end connected to power and data cables attached to the soffit and a distal end where the power and data cables are suspended therefrom; and one or more switching hubs, each of the switching hubs are arranged to be removably mounted to a mobile station moveable within the environment, to be removably connected to the power and data cables suspended from the distal end of the moveable arm of one of the booms, and to be removably connected to at least one computer in the environment to distribute power and data to the at least one computer.

A multifunction LED lighting device improves technical and functional performance compared to known lighting appliances, while also optimizing yield and satisfying demand for aesthetics and reduced consumption. The device includes: a lighting body including an LED assembly; a frame for connecting to the wall and supporting the at least a lighting body; an electrical connection and mechanical connection between the frame and the at least a lighting body; and an electronic circuit board for converting to low voltage and supplying power to the LED assembly. The lighting body is substantially L-shaped and includes an upright and a projecting arm.
