Abstract

A lighting fixture structure for a recessed lighting fixture includes a housing and a junction box. The lighting fixture structure further includes an arm. The arm is attached to the housing and to the junction box. The arm is rotatably attached to the housing.

First claim

What is claimed is:

1. A lighting fixture structure for a recessed lighting fixture, comprising:
a housing;
a junction box; and
an arm extending between the housing and the junction box, wherein the arm is attached to the junction box, wherein the arm is attached to and rotatable about an attachment area of the housing, wherein the housing includes a housing top that extends above a cylindrical section of the housing, wherein the housing top includes a top wall and a substantially flat side wall, wherein the substantially flat side wall includes the attachment area, wherein the arm includes a wireway and a wire opening that is formed through a wall of the arm, and wherein the wireway and the wire opening are used for routing one or more electrical wires between the junction box and an inside of the housing.

2. The lighting fixture structure of claim 1 , wherein the housing top includes a base section that is below the attachment area and at a top end of the cylindrical section of the housing.

3. The lighting fixture structure of claim 1 , wherein the arm is made from sheet metal.

4. The lighting fixture structure of claim 2 , wherein a first portion of the wireway is formed in a first section of the arm and wherein a second portion of the wireway is formed in a second section of the arm between an arm cover and a surface of the arm.

5. The lighting fixture structure of claim 2 , wherein the junction box is fixedly attached to the arm such that the junction box is rotatable along with the arm.

6. The lighting fixture structure of claim 5 , wherein the arm is rotatable in a range of 45 degrees.

7. The lighting fixture structure of claim 2 , wherein the housing includes a second wire opening for routing the one or more electrical wires into the inside of the housing and wherein the second wire opening of the housing at least partially overlaps with the wire opening of the arm.

8. The lighting fixture structure of claim 7 , wherein the second wire opening is formed in the housing top.

9. The lighting fixture structure of claim 1 , wherein the arm includes an arcuated slot, wherein a pin extends through the arcuated slot, and wherein the pin is fixedly attached to the attachment area of the housing through the arcuated opening.

10. The lighting fixture structure of claim 9 , wherein the arm includes a second arcuated opening, wherein a second pin extends through the second arcuated slot, and wherein the second pin is fixedly attached to the attachment area of the housing through the second arcuated opening.

11. A recessed lighting fixture, comprising:
a light source;
a housing, wherein the light source is disposed in the housing;
a junction box; and
an arm extending between the housing and the junction box, wherein the arm is attached to the junction box, wherein the arm is attached to and rotatable about an attachment area of the housing, wherein the housing includes a housing top that extends above a cylindrical section of the housing, wherein the housing top includes a top wall and a substantially flat side wall, wherein the substantially flat side wall includes the attachment area, wherein the arm includes a wireway and a wire opening that is formed through a wall of the arm, and wherein the wireway and the wire opening are used for routing one or more electrical wires between the junction box and the light source.

12. The recessed lighting fixture of claim 11 , wherein the housing top includes a base section that is below the attachment area and at a top end of the cylindrical section of the housing.

13. The recessed lighting fixture of claim 11 , wherein the attachment area is offset inward from a perimeter of the cylindrical section and directly above a cavity of the cylindrical section.

14. The recessed lighting fixture of claim 12 , wherein a first portion of the wireway is formed in a first section of the arm and wherein a second portion of the wireway is formed in a second section of the arm.

15. The recessed lighting fixture of claim 12 , wherein the housing includes a second wire opening for routing the one or more electrical wires to the inside of the housing, and wherein the second wire opening of the housing at least partially overlaps with the wire opening of the arm.

16. The recessed lighting fixture of claim 11 , wherein the arm includes an arcuated opening and wherein a pin is fixedly attached to the attachment area of the housing through the arcuated opening.

17. The recessed lighting fixture of claim 16 , wherein the arm includes a second arcuated opening and wherein a second pin is fixedly attached to the attachment area of the housing through the second arcuated opening.

18. A method of assembling a lighting structure, comprising:
attaching a junction box to an arm;
attaching the arm rotatably to an attachment area of a housing such that the arm is rotatable about the attachment area of the housing, wherein the housing includes a housing top that extends above a cylindrical section of the housing, wherein the housing top includes a top wall and a substantially flat side wall, and wherein the substantially flat side wall includes the attachment area; and
routing one or more electrical wires between the junction box and an inside of the housing through a wireway of the arm, a wire opening of the arm, and a wire opening of the housing, wherein the wire opening of the housing at least partially overlaps the opening of the arm that is formed through a wall of the arm.

19. The method of claim 18 , wherein attaching the arm rotatably to the housing comprises:
inserting a pin through an arcuated opening of the arm; and
attaching the pin to the housing through the arcuated opening.

20. The method of claim 19 , wherein attaching the arm rotatably to the housing comprises:
inserting a second pin through a second arcuated opening of the arm; and
attaching the second pin to the housing through the second arcuated opening, wherein the wire opening of the arm is between the arcuated opening and the second arcuated opening.
