Abstract

A luminaire includes a housing defined by a pair of sidewalls, a bottom wall, and a first end wall. The first end wall has a first open-ended slot adapted to receive one or more wires. The luminaire also includes a first bracket removably coupled to the first wall to partially close the open-end of the first slot such that a hole remains. The hole is adapted to securely retain the one or more wires. The luminaire further includes a closure coupled to the housing and configured to close the housing. The closure is configured to include one or more light-emitting components.

Claims

1. A luminaire, comprising:

a housing defined by a pair of sidewalls, a bottom wall, and a first end wall, the first end wall having a first open-ended slot adapted to receive one or more wires;

a first bracket removably coupled to the first wall to partially close the open-end of the first slot such that a hole remains, the hole adapted to securely retain the one or more wires; and

a closure coupled to the housing and configured to close the housing, the closure adapted to include one or more light-emitting components.

2. The luminaire of claim 1, wherein when the first bracket is coupled to the first wall and the closure is closed, a top surface of the first bracket is configured to sealingly engage the closure to seal the luminaire to the ingress protection (IP) 66 standard.

3. The lighting system of claim 1, wherein each of the one or more light-emitting components is selected from a group consisting of a fluorescent bulb, an incandescent bulb, and a light-emitting diode (LED).

4. The luminaire of claim 1, wherein the first bracket has first and second legs and a U-shaped slot defined by the first and second legs, the first and second legs being secured to the housing, and the U-shaped slot corresponding to the open-ended slot.

5. The luminaire of claim 1, wherein the first bracket includes first and second feet that project outwardly from the first and second legs, respectively, the first bracket configured to be removably coupled to the first wall via the first and second feet.

6. The luminaire of claim 5, wherein each of the first and second feet defines a notch configured to receive a fastener to removably couple the first bracket to the first wall.

7. The luminaire of claim 1, wherein at least one of the housing and the first bracket is made of stainless steel.

8. The luminaire of claim 1, wherein the first open-ended slot has a U-shape.

9. The luminaire of claim 1, wherein the housing has a second end wall, the second-end wall defining a second open-ended slot adapted to receive the one or more wires, and the luminaire further comprises a second bracket removably coupled to the second wall to partially close the open-end of the second slot such that a hole remains, the hole adapted to securely retain the one or more wires.

10. The luminaire of claim 1, wherein the closure is configured to close the housing via a plurality of rotary latches.

11. The luminaire of claim 1, wherein the closure includes a gasket, and wherein when the first bracket is coupled to the first wall and the closure is closed, a top surface of the first bracket is configured to sealingly engage the gasket to seal the luminaire to the ingress protection (IP) 66 standard.

12. A lighting system, comprising:

a first luminaire comprising a first housing and a first closure coupled to the first housing and configured to close the first housing, the first housing defined by a pair of sidewalls, a bottom wall, and a first end wall, the first end wall having a first open-ended slot, and the first closure adapted to include one or more light-emitting components;

a second luminaire positioned proximate to the first luminaire, the second luminaire comprising a second housing and a second closure coupled to the second housing and configured to close the second housing, the second housing defined by a pair of sidewalls, a bottom wall, and a second end wall, the second end wall positioned proximate to the first end wall of the first housing and having a second open-ended slot, and the second closure adapted to include one or more light-emitting components;

a bracket removably coupled to at least one of the first and second end walls and configured to partially close the open-end of the first slot such that a first hole remains and partially close the open-end of the second slot such that a second hole remains, the first and second holes adapted to accommodate passage of one or more wires.

13. The lighting system of claim 12, wherein when the bracket is coupled to the first and second walls and the first and second doors are closed, a top surface of the bracket is configured to sealingly engage the first and second closures to seal the first and second luminaires, respectively, to the ingress protection (IP) 66 standard.

14. The lighting system of claim 12, further comprising one or more wires configured to supply power to the first and second luminaires, the one or more wires extending through the first luminaire, seated in the first hole, seated in the second hole, and extending through the second luminaire.

15. The lighting system of claim 12, wherein the first and second luminaires are arranged in an end-to-end series with the first and second end walls adjacent to one another.

16. The lighting system of claim 12, further comprising a sealing element coupled to and disposed between the first and second luminaires.

17. The lighting system of claim 12, wherein each of the one or more light-emitting components is selected from a group consisting of a fluorescent bulb, an incandescent bulb, and a light-emitting diode (LED).

18. The lighting system of claim 12, further comprising a driver box including a driver configured to electrically power the first and second luminaires via one or more wires.

19. The lighting system of claim 18, wherein the driver box is located remotely from the first and second luminaires.

20. The lighting system of claim 12, wherein the first luminaire has a third end wall opposite the first end wall, the lighting system further comprising a transition box coupled to the third end of the first luminaire such that a third hole is formed, the third hole adapted to accommodate passage of the one or more wires.

21. The lighting system of claim 12, wherein the bracket is removably coupled to the first and second end walls and configured to partially close the open-end of the first slot such that the first hole remains and partially close the open-end of the second slot such that the second hole remains.

23. The transition bracket of claim 21, further comprising a first pair of feet coupled to and projecting outwardly from the first pair of legs, and a second pair of feet coupled to and projecting outwardly from the second pair of legs.

24. The transition bracket of claim 21, wherein the first and second feet are perpendicular to the body of the bracket.

25. The transition bracket of claim 24, wherein the first and second feet each include a notch configured to receive a fastener to couple the first and second feet to the bottom surface of the housing.

26. The transition bracket of claim 21, wherein the body, the first pair of legs, and the second pair of legs are made of stainless steel.

27. The transition bracket of claim 21, further comprising a gap defined between the first pair of legs and the second pair of legs, the gap configured to accommodate the first end wall of the housing.

22. A transition bracket for a luminaire having a housing defined by a pair of sidewalls, a bottom wall, and a first end wall, the first end wall having a first open-ended slot configured to receive a wire, the transition bracket comprising:
