Abstract

An edge-lit lighting structure includes a first end panel and a second end panel. The edge-lit lighting structure further includes a first side panel extending between the first end panel and the second end panel at a first longitudinal side of the edge-lit lighting fixture. The edge-lit lighting structure also includes a second side panel extending between the first end panel and the second end panel at a second longitudinal side of the edge-lit lighting fixture opposite the first longitudinal side. Further, the edge-lit lighting structure includes a center beam having a hollow portion. The center beam is positioned between the first side panel and the second side panel and is attached to the first end panel and the second end panel.

First claim

What is claimed is:

1. An edge-lit lighting fixture, comprising:
a first light emitting panel (LEP), wherein light from a first light emitting diode (LED) that enters the first LEP through a narrow side of the first LEP is emitted through a broad side of the first LEP and wherein the narrow side of the first LEP is narrower than the broad side of the first LEP;
a second LEP, wherein light from a second LED that enters the second LEP through a narrow side of the second LEP is emitted through a broad side of the second LEP and wherein the narrow side of the second LEP is narrower than the broad side of the second LEP; and
an edge-lit lighting structure comprising:
a first end panel;
a second end panel;
a first side panel extending between the first end panel and the second end panel at a first longitudinal side of the edge-lit lighting structure;
a second side panel extending between the first end panel and the second end panel at a second longitudinal side of the edge-lit lighting structure opposite the first longitudinal side; and
a center beam having a hollow portion and a cover positioned on a lower side of the center beam below the hollow portion, the cover hiding the hollow portion from view, the center beam positioned between the first side panel and the second side panel and attached to the first end panel and the second end panel, wherein the first LEP and the second LEP are positioned between the first side panel and the second side panel and wherein the center beam is separated by a first space from the first side panel and by a second space from the second side panel.

2. The edge-lit lighting fixture of claim 1 , further comprising:
a first end cap positioned on an outer side of the first end panel and attached to first end panel; and
a second end cap positioned on an outer side of the second end panel and attached to second end panel.

3. The edge-lit lighting fixture of claim 1 , further comprising a first LEP bracket and a second LEP bracket, wherein the first LEP bracket is attached to the first end panel and wherein the second LEP bracket is attached to the second end panel, and wherein the center beam is attached to the first end panel using the first LEP bracket.

4. The edge-lit lighting fixture of claim 1 , further comprising a light emitting diode (LED) driver positioned within the center beam.

5. The edge-lit lighting fixture of claim 4 , wherein a first LED is positioned proximal a narrow side of the first LEP and wherein a second LED is positioned proximal a narrow side of the second LEP.

6. The edge-lit lighting fixture of claim 5 , further comprising:
a first heat sink positioned to dissipate heat from the first LED; and
a second heat sink positioned to dissipate heat from the second LED.

7. The edge-lit lighting fixture of claim 1 , wherein the first LEP and the second LEP are rotatably attached to the first end panel and to the second end panel.

8. The edge-lit lighting fixture of claim 1 , wherein the center beam is made from sheet metal.

9. An edge-lit lighting fixture, comprising:
a first light emitting panel (LEP), wherein light from a first light source that enters the first LEP through a narrow side of the first LEP is emitted through a broad side of the first LEP and wherein the narrow side of the first LEP is narrower than the broad side of the first LEP;
a second LEP, wherein light from a second light source that enters the second LEP through a narrow side of the second LEP is emitted through a broad side of the second LEP and wherein the narrow side of the second LEP is narrower than the broad side of the second LEP; and
an edge-lit lighting structure comprising:
a first end panel;
a second end panel;
a first side panel extending between the first end panel and the second end panel at a first longitudinal side of the edge-lit lighting structure;
a second side panel extending between the first end panel and the second end panel at a second longitudinal side of the edge-lit lighting structure opposite the first longitudinal side; and
a center beam having a hollow portion, the center beam positioned between the first side panel and the second side panel and attached to the first end panel and the second end panel, wherein the first LEP is positioned between the center beam and the first side panel and wherein the second LEP is positioned between the center beam and the second side panel.

10. The edge-lit lighting fixture of claim 9 , further comprising:
a first end cap positioned on an outer side of the first end panel and attached to first end panel; and
a second end cap positioned on an outer side of the second end panel and attached to second end panel.

11. The edge-lit lighting fixture of claim 9 , further comprising a light emitting diode (LED) driver positioned within the center beam.

12. The edge-lit lighting fixture of claim 9 , wherein the first LEP and the second LEP are rotatably attached to the first end panel and to the second end panel.
