A light fixture is configured to receive a module that can add certain functionality to the light fixture and/or alter the way the light fixture is controlled. The light fixture includes a module receiver configured to receive one of a plurality of modules. When a first module is coupled to the light fixture, the light fixture has a first range of functionality dictated at least in part by the functionality of the first module. When the first module is removed and replaced with a second module, the light fixture has a second range of functionality dictated at least in part by the functionality of the second module.

A LED lighting system includes a soundproofing attachment, referred to as an acoustic shroud. The lighting system includes LED light fixtures with the acoustic shroud made from sound dampening materials formed into a sleeve or panels, which can be slipped on an off an LED light fixture unit. The system can include quick-release fasteners for affixing and removing the shroud from an uninstalled or installed light fixture. Quick-release fasteners can enable the attachment of the shroud to accommodate multiple types of light fixtures and installation methods, such a wall or suspended ceiling lighting designs, as well as allow for the adjustment of the position of the shroud in relationship to the LED light fixture unit.

A flexible operating room lighting system may be coupled to a wall, ceiling, or fixture of a facility. The lighting system can modularly accommodate multiple illumination arms and incorporate one or more microphone thereon, permitting the vocal control using a processor for hands free operations. The lighting system may include a speaker and a camera to facilitate two-way communications with a user to facilitate demonstrations for individuals undergoing tutelage in the particular facility's profession. The lighting system may employ a stand with wheels to facilitate modularity. Further, a cover with a transparent front end may be provided to be slipped over the lighting system and securing through a cover fastener. By providing each illumination arm with a jack, the illumination arm may be modularly assigned, replaced, sanitized. Thus, the present invention provides reliable sanitary measures while further facilitating a flexible operable device through the illumination arms.

Disclosed are mounting brackets, mounting bracket assemblies, mountable lights, and methods of installation thereof. In one embodiment, a mounting bracket assembly comprises an obround-shaped wall mount configured to be mounted to a wall and a light mount configured to be coupled to a surface of a light. The wall mount comprises a raised internal ridge extending from a wall-facing side of the wall mount and a rim segment surrounding the raised internal ridge. A clearance space can be formed in between the wall and the rim segment when the wall mount is mounted to the wall. The light mount comprises a curved ledge and an inwardly-projecting brim. At least part of the curved ledge can rest on a top of the wall mount and the inwardly-projecting brim can be positioned within part of the clearance space when the light is mounted to the wall.

A notification appliance is disclosed. The notification appliance may be a strobe notification appliance, such as an LED strobe notification appliance. The notification appliance may be wall-mounted or ceiling-mounted. Further, the notification appliance may include an optic that is configured to shape the light output from the notification appliance. For example, in a wall-mount, the optic may be mounted off-axis of a plane defined by a back plate of the notification appliance. Further, the notification appliance may be composed of a back plate, a driver board, and a front housing, with the front housing being attached to one or both of the back plate and the driver board. Moreover, the notification appliance may be used with an adapter bracket, which may be used to connect the notification appliance with one or more types of junction boxes.

According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, a light emitting diode (LED) mounted to the circuit board and configured to emit light, a lens disposed over the LED having a bottom surface facing the circuit board, a top surface opposite the bottom surface, and a lateral surface between the top and bottom surfaces, and an elastomer encapsulating at least part of the circuit board. The elastomer may not be in contact with at least part of the lateral surface of the lens so as to form a gap between the elastomer and the lateral surface of the lens.

The present disclosure sets forth an outdoor security light with the flexibility of being mounted to either a wall structure or to an eave or ceiling structure. The security light can be adjusted for each installation without the necessity of changing hardware elements of the security luminaire. Disclosed designs include a luminaire housing having a housing mount which is removably received within a housing mount attached to a structure. An electrical interface between the two may be provided to provide electrical power to the luminaire housing and provide communication therebetween.

Example embodiments provide lighting fixture mounting kits for mounting a flat panel lighting fixture to a mounting surface. One mounting kit comprises a mounting frame and a lighting fixture. When the mounting frame is secured to the mounting surface, a junction box is accessible therethrough. The mounting frame and lighting fixture are shaped for engagement and attachment to one another. Another mounting kit comprises a mounting plate and a lighting fixture. The mounting plate may comprise indexing tabs for alignment with corresponding indexing slots of the lighting fixture and extending outwardly from a plate portion of the mounting plate. The lighting fixture may comprise a back portion having therein one or more indexing slots for receiving an indexing tab therein. Insertion of the indexing tab into the indexing slot guides the engagement of the lighting fixture with the mounting plate.

Multi-function lighting fixtures are provided. In one example implementation, a lighting fixture may include an optical housing extending lengthwise between a first end and a second end. The optical housing may include a plurality of light sources disposed within an interior of the optical housing and a plurality of optical elements disposed along an exterior of the optical housing. The optical housing may also a plurality of sections defined within the interior of the optical housing. Each of the optical sections may be associated with a separate light source of the plurality of light sources and a separate optical element of the plurality of optical elements.

Electrical devices with lights having onboard secondary power supplies are configured with synchronizable zone-based operation and/or color selectable modes. The electrical devices can be power receptacles and can be connected to a line input of a power circuit of a power grid and can also have the onboard secondary (emergency power) power supplies. The devices are configured so that respective lights can automatically illuminate upon motion detection in a zone and/or upon a disruption to the power circuit or to a powered state of a particular electrical device. The devices can be configured to allow a user to select different color or color temperatures using a color selection circuit.
