Abstract: A low-profile modular lighting device with flexible installation mounting options includes a lower housing, a circuit board supported by the lower housing and having electronic devices mounted thereto, and a plurality of upper housings each configured to releasably couple to the lower housing. The electronic devices of the circuit board extend within the space defined by an interior surface and upper edge of the lower housing and within the space defined by an interior surface and lower edge of each of the plurality of upper housings when coupled to the lower housing. Each of the plurality of upper housings provide a different mounting configuration for the modular lighting device. The modular lighting device may include one or more of a motion sensor, a light sensor, and a wireless transceiver for communication with a wireless lighting system.

Abstract: An LED light fixture includes a heat dissipation structure defining a first housing member and a plurality of concentric fin sets. A circuit board is thermally coupled to a side of the first housing member opposite the concentric fin sets, a plurality of light emitters is thermally coupled and mounted to a region of the circuit board overlying a first set of concentric fins, and a driver circuit is coupled and mounted to a region of the circuit board overlying a second set of concentric fins. A reflector spans between the circuit board and a second housing member, and a lens spans between the first and second housing member and provides light transmission therethrough.

Abstract: A device for a wireless device control system for controlling lighting devices is disclosed. The device can include a wireless transceiver, a power loss detection circuit, a communication loss detection circuit, a power monitoring circuit, and an output circuit. The device is configurable to provide a preselected communication loss action upon detecting communication loss, a preselected power loss action upon detecting power loss, and a preselected load power fault action upon detecting a load power fault.

Abstract: A lighting fixture configured to expand and collapse, and methods for expanding and collapsing a light fixture are disclosed. Embodiments of the lighting fixture include a lighting fixture with a movable section that collapses into at least one cavity in a base housing for storage and shipment, and extends from the cavity for operation. In the collapsed configuration the lighting fixture fits into a smaller container than when the lighting fixture is in the expanded configuration. In some embodiments a locking member locks the movable section into its extended position and can be retracted by a user by manually disengaging the locking member. Accessories and extenders that can be attached to the lighting fixture can be stored in the one or more cavities into which the movable section is stowed in the collapsed configuration.

Abstract: A light fixture includes a central housing, a panel, a light source, and a tether. The central housing defines first and second side surfaces and a bottom surface, and the bottom surface defines a plane. The panel is pivotably coupled with the first side surface, and the light source is coupled with the panel. The tether is coupled at one end with the panel to pivotably suspend the panel, and the second end of the tether includes an attachment member. The attachment member is configured to selectively couple with any one of a plurality of anchor positions located on the central housing. The panel is therefore fixable between a plurality of angles relative to the plane as determined by the attachment member being coupled with a selected one of the plurality of anchor positions.

Abstract: A wireless controller for detecting events and controlling illumination of one or more light fixture is disclosed. The device includes a wireless transceiver, a processor, an input sensor, and an output control module. The wireless controller can be used with a the wireless lighting control system, including one using a wireless mesh network. The controller is configurable for the input sensor and output control module operating in either an interdependent mode or an independent mode. In the interdependent mode the input sensor and output control module are logically/functionally related, and in the independent mode the input sensor and output control module are logically/functionally unrelated.

Abstract: Systems and methods that permit initial selection of a lighting fixture output characteristic and inhibit later change of the lighting fixture output characteristic are disclosed. Embodiments include one or more devices that inhibit a lighting fixture control switch from being moved between two different positions. In some embodiments the control switch extends through an aperture in the a housing of the lighting fixture and the one or more devices are inserted into the aperture and embrace the control switch in one of the control switch's operational positions. In some embodiments the configuration of the apertures and the devices permits the devices to be inserted into the apertures in a single orientation. Some embodiments include devices with an outer surface that defines the switch embracing portion, and some embodiments include devices that are difficult to remove by hand after insertion into the aperture.

Abstract: A luminaire includes a first plurality of lighting elements, a housing, and a first lightguide. The housing includes a body and first and second edge frames coupled with the body. The first and second edge frames are positioned on opposing sides of the body and are separated by a first distance. The first plurality of lighting elements is further positioned on the first edge frame. The first lightguide is positioned along the first edge frame in proximity to the first plurality of lighting elements and is configured to receive light from the first plurality of lighting elements. Further, the first lightguide extends a second distance along a plane toward the second edge frame, with the second distance being less than the first distance.

Abstract: An illustrative light fixture provides an emitter housing and a driver housing in a single fixture with an airflow channel defined between the emitter and driver housings. The airflow channel minimizes thermal conduction between the emitter and driver housings, and maximizes thermal convective cooling for at least one of the emitter housing and driver housing. The emitter housing includes vertical fins extending into the airflow chamber. The left and right sides of the emitter and driver housings define top and bottom edges that are respectively coplanar with the top and bottom edges of the vertical fins.

Abstract: Apparatuses and methods for accessing luminaire mounting and/or electrical connection compartments and components are disclosed. Embodiments include a front reflective door pivotally attached to a luminaire housing with a closed position covering an opening to the mounting access compartment and an open position allowing easy user access to the mounting feature(s) in the mounting access compartment. In some embodiments the door forms an exterior surface of the lighting fixture, while in additional embodiments the luminaire's light source is mounted on the luminaire housing and not on the door. In still further embodiments the light source is located externally to the mounting access compartment so that the light source is outside the door when the door is closed. In yet further embodiments the free end of the door is adjacent the light source while the pivoting end of the door is located away from the light source.
