Abstract: A mounting system for a recessed light fixture includes a frame and a holder supported by the frame. The holder includes a base and a support portion extending from the base. The support portion includes a top end, a bottom end opposite from the top end, and an edge extending from the top end to the bottom end. The edge includes a transition portion between the top end and the bottom end, a first step between the bottom end and the transition portion, and a plurality of second steps between the first step and the transition portion. At least one characteristic of the first step is different from each second step.

Abstract: A light fixture, such as but not limited to an outdoor light fixture, may include features or elements allowing for enhanced resistance to water ingress and/or enhanced thermal management of components. Such features or elements may be provided between a housing of the light fixture and a lens of the light fixture and/or between the housing of the light fixture and an end cap of the light fixture. Some features or elements may limit thermal expansion and contraction of a lens of the light fixture over a wide range of temperatures.

Abstract: A light fixture includes a main body, at least a portion of which is generally cylindrical, the main body having an open side, and one or more light sources disposed within the main body. The light fixture further includes one or more mounting rings configured to substantially encircle the main body and configured for mounting the light fixture. A diffuser may be provided, covering the open side of the main body and enclosing the one or more light sources within the light fixture.

Abstract: A retrofit kit for a light fixture includes a light engine and a mounting bracket. In some aspects, a method of installing the retrofit kit in a light fixture includes installing a mounting bracket in a housing of the light fixture, and placing a light engine in a temporary hanging position. In the temporary hanging position, a hook of a first engine flange of the light engine rests on the mounting bracket and a second engine flange of the light engine opposite from the first engine flange is spaced apart from the mounting bracket.

Abstract: A light fixture includes an electronic accessory module such as a wireless communication module, and a clip for mounting the accessory module to a panel of the light fixture. The clip includes features for snapping the accessory module to a panel of the light fixture, for example to a printed circuit board holding light emitting diodes or to a sheet metal panel that is part of the structure of the light fixture. The clip may hold the accessory module electronics away from any metal parts of the light fixture. In the case that the accessory module is a wireless communication module, this spacing may facilitate robust wireless communication.

Abstract: Retrofit kits for retrofitting LED light engines into existing light fixture housings. The retrofit kit includes a hook bracket that may be mounted in the housing and from which an end of the LED light engine can be suspended so as to permit an installer to electrically connect the LED light engine. The retrofit kit also includes a mounting bracket to secure the free end of the LED light engine into the housing after the LED light engine has been rotated upwardly into the housing from the hanging position.

Abstract: A Bluetooth beacon for a luminaire assembly includes a module and an antenna associated with the module. The Bluetooth beacon is monted such that the antenna is communicatively visible from a light emitting side of the luminaire assembly. The Bluetooth beacon is configured to provide a signal extending a predetermined distance from the luminaire assembly such that a Bluetooth receiver on a user device can receive a signal from the Bluetooth beacon.

Abstract: Described are embodiments of a light engine installation kit and methods of installation that allow a single technician to install large, heavy, or awkwardly shaped light engines into new or existing fixture housings. The installation kits include mounting brackets that install into the fixture housing. The mounting brackets can then support the light engine by a retention tab at one end, and a tether at the other. In this intermediate position, an installer can complete the wiring before raising the light engine into its final position. Also described are lenses, wireway covers, reflectors, and end caps that provide improved sealing of the lens compartment of a light engine. The fitting of the parts provides better sealing to prevent dirt, debris, or insects from migrating into the lens compartment of the light engine and causing reduced light output or unsightly dark spots in the lens.
