A lighting fixture that includes a frame, a heat sink assembly, an LED assembly, and a reflector. The frame includes a first end plate and a second end plate, each end plate including a slot formed therein. The slot extends from a top edge of the end plates towards a bottom edge of the end plates. The heat sink assembly includes one or more LEDs and a lightguide having a first longitudinal edge that receives light emitted from the LEDs. A first edge and a second edge of the lightguide are slidably inserted into respective slots. The heat sink assembly includes a heat sink base and a heat sink cap coupled thereto which forms a first cavity for housing the LEDs and a second cavity adjacent the first cavity for housing a portion of the lightguide. The reflector is coupled to the end plates.

Edgelit LED blade fixture

An edgelit recessed luminaire includes a housing that defines an inner cavity and has a pair of side panels. Each side panel includes one or more torsion spring receivers. Further, the edgelit recessed luminaire includes a light engine that includes torsion springs that are pivotally coupled to the light engine via torsion spring brackets. The light engine is removably coupled to the housing such that in an open position, the light engine is suspended from the housing via the torsion springs providing access to the inner cavity and in a closed position, the light engine covers the inner cavity of the housing. Alternatively, a linear light module is removably coupled to the housing.

Edgelit recessed luminaire

Embodiments described herein are directed to a lighting fixture including a lightguide that distributes light from a major surface, a light assembly including light sources arranged linearly, and a frame including a means for providing a force that urges the light assembly against an edge of the lightguide. A standoff or spacer can provide an air gap between a light source of the light assembly and the waveguide edge. In various embodiments, the lighting fixture may incorporate a spring, a spring finger, a spring clip, a screw, or other means for securing the light assembly against the edge of the lightguide. In this manner, substantially all light provided by the light assembly is emitted into the edge of the lightguide. The fixture is formed to accommodate tolerances among elements of the lighting fixture, while maintaining the light assembly securely against the edge of the lightguide.

Edgelit lighting fixture and assembly

A lighting fixture can be upgraded from utilizing a fluorescent-based light source to utilizing a light source based on light emitting diode (LED) technology. The upgrade can be completed while the fixture is mounted at an installation, or the fixture can be taken down temporarily during the upgrade. One or more fluorescent tubes in the fixture can be removed and replaced with an LED-based light engine. The light engine can include LEDs, an LED driver, and a lightguide, which may be slab-shaped. The LEDs can couple light into the lightguide, and the lightguide can distribute the coupled light. A bracket system can mount the new light engine to a frame of the lighting fixture. If the lighting fixture has a ballast, the ballast can remain attached to the fixture frame during and after the upgrade or be removed, for example.

Method and system for retrofitting luminaires

A lighting fixture that includes a frame, a heat sink assembly, an LED assembly, and a reflector. The frame includes a first end plate and a second end plate, each end plate including a slot formed therein. The slot extends from a top edge of the end plates towards a bottom edge of the end plates. The heat sink assembly includes one or more LEDs and a lightguide having a first longitudinal edge that receives light emitted from the LEDs. A first edge and a second edge of the lightguide are slidably inserted respective slots. The heat sink assembly includes a heat sink base and a heat sink cap coupled thereto which forms a first cavity for housing the LEDs and a second cavity adjacent the first cavity for housing a portion of the lightguide. The reflector is coupled to the end plates.

Edge-lit luminaire strip

A lighting fixture includes a housing channel and a heat sink assembly coupled to the housing channel. The heat sink assembly includes a heat sink base and a heat sink clamp that are coupled together via a fastener to retain a waveguide to the lighting fixture. In particular, the fastener is disposed at an acute angle relative to the respective waveguide. Further, the lighting fixture includes one or more light sources coupled to the heat sink base and oriented such that light emitted by the one or more light sources enters an edge of the waveguide. Furthermore, the lighting fixture includes an end cap that covers an open lateral end of the housing channel. Further, the end cap operates as an alignment bracket to couple the lighting fixture to a second lighting fixture adjacent the open lateral end of the housing channel of the lighting fixture.
