Abstract: A luminaire includes one or more light emitting diodes (LEDs) and a beam-spreading total internal reflection (TIR) optic optically coupled with the one or more LEDs and configured to spread light output by the one or more LEDs. The beam-spreading TIR optic includes a base and an apex and a tapered sidewall extending from a perimeter of the base to the apex, and the one or more LEDs are optically coupled into the base. There may be N LEDs where N is an integer greater than or equal to two, and the beam-spreading TIR optic may further include N optical condensers connected to the base, with each LED optically coupled into the base by a corresponding optical condenser. The luminaire may further include peripheral white LEDs disposed around the beam-spreading TIR optic, which are not optically coupled with the beam-spreading TIR optic. A surrounding annular reflector may further be provided.

Abstract: Methods, apparatus and systems for facilitating installation and/or replacement of linear lighting assemblies with linear light-emitting diode (LED) luminaires. In an embodiment, a system for installing a linear LED luminaire includes a suspension bracket having a connection feature for connection to a connection point, and an attachment portion for accepting a first distal end of a first linear LED luminaire. The system also includes a connecting bridge that includes a bridge housing, at least one aperture formed in the bridge housing, and at least one locking tab. The connecting bridge attaches to a second distal end of the first linear LED luminaire and enables secure mechanical and electrical connection between the first linear LED luminaire and a second LED luminaire.

Abstract: In some embodiments, aspects of this disclosure provide a system including a reflector of a suspension lighting fixture, the reflector having a reflective underside and a top side; at least two ribs affixed to the top side of the reflector; and a tray base is attached between two adjacent ribs of the at least two ribs. A benefit is that a tray base (and other components attached thereto) may be efficiently positioned at various positions along the length of the reflector.

Abstract: Provided is a light fixture including an end portion that features a mechanism configured to lock the light fixture via the end portion to another end portion disposed at one extremity of another light fixture. The mechanism also includes a lever configured to lock the light fixture with the other end portion.

Abstract: Provided is a light-emitting diode retrofit lighting apparatus for an existing light fixture that includes one or more lamp holders. The apparatus includes a base portion to be mounted to the light fixture, a light-emitting diode mounting part connected with the base portion and configured to receive a light-emitting diode lighting source, an adjustment portion to be received within the base portion and configured to adjust the apparatus in a vertical direction, and at least one sliding mechanism configured to be mounted on and slide along the adjustment portion to adjust the one or more lamp holders in a horizontal direction.

Abstract: There is provided a light fixture that includes a mechanism for attaching the light fixture to another light fixture. The mechanism includes a set of retractable hooks configured to mate with an end of the other light fixture to attach the light fixture to the other light fixture.

Abstract: Provided is a device configured for attachment to a lighting fixture. The device includes an engagement mechanism that allows the lighting fixture to be mounted within a recess of a substantially flat surface. The engagement mechanism is constructed to facilitate movement of a tension mechanism from a maximum tension position to a minimum tension position. Movement of the engagement mechanism is in response to an applied force generated by contact of the engagement mechanism with a first side of the substantially flat surface. Also provided is a method for mounting the lighting fixture using the engagement mechanism.

Abstract: Suspended lighting fixtures are described that include one or more light sources and a lens component that minimizes and/or eliminates unwanted shadows caused by debris such as dust and/or insects. In some embodiments, the suspended light fixture includes a housing, at least one light source operably connected to the housing, and a lens element operably connected to the housing. The lens element includes a tip portion and a debris hiding feature, wherein the debris hiding feature at least minimizes undesirable shadows that occur when light emitted from the at least one light source impinges on the debris that settled on an interior of the tip portion.

Abstract: The specification and drawings present a new apparatus such as a lighting fixture and a method for replacing a light engine such as a LED light engine in the lighting fixture by replacing one part carrying the light engine, where the heat sink (e.g., extruded elongated heat sink) can be split into two parts, a replaceable part carrying the light engine and a fixed part. Both heat sink parts may be attached together with a clip to allow the unclipping and replacement of the removable part carrying the light engine. The geometry of the two heat sink parts can be designed in such a way that one part can be attached on top of the other, while providing a predefined alignment and continuous thermal conductivity between the two parts. A space between the two parts can be used to place the clip.

Abstract: Provided is a connection housing including a first plate having a connecting member for slidably connecting the first plate to an electrical assembly. The first plate includes a ridge portion formed across a threading path. A second plate has an opening for non-slidably connecting the second plate to the electrical assembly. The second plate includes a valley portion positioned in opposing relation to the ridge portion. The first and second plates are configured for (i) facilitating placement of a wire along the threading path and (ii) folding onto each other to restrict movement of the wire after the folding.
