Abstract

A light fixture and wireway assembly is provided in a low-profile configuration wherein at least a portion of a plurality of wireways are disposed in a stacked configuration with a low-profile, edge-lit LED light engine. In one configuration, at least portions of two to four individual wireways are disposed in a stacked configuration with a low-profile, edge-lit LED light engine powered by an LED power supply also disposed within the outer perimeter of the overall assembly. Each wireway can be accessed through a single wireway wall without requiring conduit outside of the outer perimeter of the assembly.

Claims

1. A wireway and light fixture assembly comprising:

an outer perimeter wall defining an interior;

the outer perimeter wall including a top wall;

an LED light engine;

at least first and second wireways disposed within the interior;

the LED light engine and the at least two wireways being disposed in a stacked configuration with portions of the at least two wireways being disposed directly between the LED light engine and the top wall;

wherein the first and second wireways are spaced from the top wall of the outer perimeter wall;

further comprising a third wireway;

at least one of the first and second wireways being connected to and extending from the third wireway;

wherein the third wireway is disposed in a stacked configuration with a portion of the third wireway disposed directly between the LED light engine and the top wall of the outer perimeter wall;

wherein the third wireway is spaced from the top wall of the outer perimeter wall;

further comprising a fourth wireway;

at least one of the first, second, and third wireways being connected to and extending from the fourth wireway; and

wherein the fourth wireway is disposed in a stacked configuration with a portion of the fourth wireway disposed directly between the LED light engine and the top wall of the outer perimeter wall.

2. The assembly of claim 1, further comprising hangers supporting the wireways from the top wall.

3. The assembly of claim 1, wherein the LED light engine is an edge-lit LED light engine.

4. The assembly of claim 1, further comprising an LED power supply disposed within the interior.

5. The assembly of claim 1, wherein an interior of each wireway is separated from the interior by only a single wireway wall.

6. The assembly of claim 1, wherein the outer perimeter wall is elongated in a longitudinal direction;

the first and second wireways being parallel to each other and to the LED light engine in the longitudinal direction.

7. The assembly of claim 1, wherein each wireway includes its own wireway door.

8. The assembly of claim 1, wherein the LED light engine selectively pivots between closed and open positions;

the open position providing access to the interior.

9. The assembly of claim 1, wherein the LED light engine is carried by a door that selectively pivots between the closed and open positions.

10. A wireway and light fixture assembly comprising:

an outer perimeter wall defining an interior;

the outer perimeter wall including a top wall;

an LED light engine;

at least first and second wireways disposed within the interior;

the LED light engine and the at least two wireways being disposed in a stacked configuration with portions of the at least two wireways being disposed directly between the LED light engine and the top wall; and

further comprising a communications wireway assembly disposed outside the outer perimeter wall;

the communications wireway assembly includes a plurality of wireways that each has its own door;

the plurality of wireways being disposed behind a common door.

11. The assembly of claim 10, wherein the LED light engine is an edge-lit LED light engine.

12. The assembly of claim 10, further comprising an LED power supply disposed within the interior.

13. The assembly of claim 10, wherein the LED light engine is selectively movable between closed and open positions with respect to the interior;

the open position of the LED light engine providing access to both of the first and second wireways.

14. The assembly of claim 13, wherein an interior of each wireway is separated from the interior by only a single wireway wall.

15. The assembly of claim 13, wherein each wireway includes its own wireway door.

16. The assembly of claim 13, wherein the LED light engine selectively pivots between the closed and open positions.

17. The assembly of claim 13, wherein the LED light engine is carried by a door that selectively pivots between the closed and open positions.

18. The assembly of claim 13, further comprising a third wireway;

at least one of the first and second wireways being connected to and extending from the third wireway.

19. The assembly of claim 18, wherein the third wireway is disposed in a stacked configuration with a portion of the third wireway disposed directly between the LED light engine and the top wall of the outer perimeter wall.

20. The assembly of claim 19, further comprising a fourth wireway;

at least one of the first, second, and third wireways being connected to and extending from the fourth wireway.

21. The assembly of claim 20, wherein the fourth wireway is disposed in a stacked configuration with a portion of the fourth wireway disposed directly between the LED light engine and the top wall of the outer perimeter wall.

22. The assembly of claim 13, wherein the first and second wireways are disposed side-by-side.

23. An wireway and light fixture assembly comprising:

an outer perimeter wall defining an interior;

the outer perimeter wall including a top wall;

an LED light engine carried by the outer perimeter wall between closed and open positions;

at least first and second wireways disposed within the interior;

the first and second wireways being spaced from the top wall;

each of the first and second wireways defining a passageway;

an LED power supply disposed within the interior;

wherein the passageway of each of the first and second wireways is separated from the interior by only a single wireway wall;

a third wireway;

at least one of the first and second wireways being connected to and extending from the third wireway;

a fourth wireway;

at least one of the first, second, and third wireways being connected to and extending from the fourth wireway; and

wherein the fourth wireway is disposed in a stacked configuration with a portion of the fourth wireway disposed directly between the LED light engine and the top wall of the outer perimeter wall.

24. The assembly of claim 23, further comprising hangers supporting the wireways from the top wall.

25. The assembly of claim 23, wherein the LED light engine is an edge-lit LED light engine.

26. The assembly of claim 23, further comprising an LED power supply disposed within the interior.

27. The assembly of claim 23, wherein the outer perimeter wall is elongated in a longitudinal direction;

the first and second wireways being parallel to each other and to the light engine in the longitudinal direction.

28. The assembly of claim 23, wherein the LED light engine and the at least first and second wireways are disposed in a stacked configuration with portions of the at least first and second wireways being disposed directly between the LED light engine and the top wall.
