Abstract
An edge-lit light emitting diode (LED) light panel includes a frame that has a first plate, a second plate, and a channel partially bounded by the first plate and the second plate. The edge-lit LED light panel also includes a plurality of light emitting diodes (LEDs) disposed in the channel, and a wave guide disposed within the frame. The wave guide has an outer perimeter edge abutting the plurality of LEDs.
Claims19
An edge-lit light emitting diode (LED) light panel, comprising:
- a frame having a first plate, a second plate, and a channel partially bounded by the first plate and the second plate;
- a plurality of light emitting diodes (LEDs) disposed in the channel;
- and
- a wave guide disposed within the frame, the wave guide having an outer perimeter edge abutting the plurality of LEDs, wherein the frame comprises a first hinge on a first member of the frame and a second hinge on a second member of the frame and wherein the edge-lit LED light panel is capable of rotating about the first hinge and the second hinge.
The edge-lit LED light panel of 5, further comprising a diffuser substantially covering a second broad surface of the wave guide, the second broad surface being opposite the broad surface, wherein the diffuser is partially disposed in the channel between the first plate and the wave guide.
The edge-lit LED light panel of 5, further comprising a back plate and a light emitting diode driver attached to the back plate, wherein the back plate is attached to the frame and substantially covers the reflector.
A troffer luminaire, comprising:
- a housing:
- and
- an edge-lit LED light panel rotatably coupled to the housing, the edge-lit LED light panel comprising:
- a frame having a first plate, a second plate, and a channel partially bounded by the first plate and the second plate;
- a plurality of light emitting diodes (LEDs) disposed in the channel;
- and
- a wave guide disposed within the frame, the wave guide having an outer perimeter edge abutting the plurality of LEDs.
The troffer luminaire of 9, further comprising a first bracket and a second bracket that are at least partially positioned inside the housing and attached to opposite sides the housing, wherein the first hinge is positioned in a first slot of a first bracket, wherein the second hinge is positioned in a first slot of a second bracket, and wherein the edge-lit LED light panel is rotatable about the first hinge and the second hinge.
A method for retrofitting a troffer luminaire with an edge-lit light emitting diode (LED) light panel, the method comprising:
- removing a light source from a troffer luminaire housing;
- coupling a first mounting bracket inside the troffer luminaire housing to a first wall of the troffer luminaire housing;
- coupling a second mounting bracket inside the troffer luminaire housing to a second wall of the troffer luminaire housing;
- coupling an edge-lit light emitting diode (LED) panel to the first mounting bracket and to the second mounting bracket.
