Abstract

An LED light fixture assembly includes an elongated first support member, an elongated second support member spaced from and substantially parallel to the first support member, and a plurality of elongated LED lighting fixtures coupled to and extending between the first support member and the second support member. Each LED lighting fixture includes an elongated structural frame member having a substantially channel shaped support portion, and a mounting portion opposite the support portion. Each LED lighting fixture also includes a plurality of LED light modules secured to and positioned along the mounting portion, and a cover extending along and supported by the mounting portion. The cover is positioned so light emitted from the plurality of LED light modules passes through the cover and away from the mounting portion.

Claims

1. An LED light fixture assembly comprising:

an elongated first support member;

an elongated second support member spaced from and substantially parallel to the first support member; and

a plurality of elongated LED lighting fixtures coupled to and extending between the first support member and the second support member, the plurality of elongated LED lighting fixtures arranged in substantially parallel and spaced-apart relation with respect to one another, and each LED lighting fixture including;

an elongated structural frame member having a substantially channel-shaped support portion, and a mounting portion opposite the support portion and having both a first wall and a second wall angled with respect to the first wall,

a plurality of LED light modules secured to and positioned along the first wall of the mounting portion, and

a cover extending along and supported by the mounting portion, the cover positioned so light emitted from the plurality of LED light modules passes through the cover and away from the mounting portion.

2. The assembly of claim 1, wherein the first and second support members extend substantially horizontally with the second support member positioned above the first support member, wherein the plurality of elongated LED lighting fixtures extend substantially vertically, and wherein the second support member is supported above the first support member by the plurality of elongated LED lighting fixtures.

3. The assembly of claim 1, wherein the support portion is substantially C-shaped and includes a pair of opposed side walls and a base wall extending between the opposed side walls.

4. The assembly of claim 3, wherein the side walls are substantially parallel to one another and the base wall is substantially perpendicular to the side walls.

5. The assembly of claim 3, wherein the mounting portion extends between distal ends of the side walls, and wherein the mounting portion and the support portion cooperate to define a closed box section.

6. The assembly of claim 1, wherein each LED lighting fixture is substantially symmetric about a central plane.

7. The assembly of claim 1, wherein each LED lighting fixture further includes an optical assembly extending between the first wall, the second wall, and the cover.

8. The assembly of claim 1, wherein the first wall defines a first slot and the second wall defines a second slot, and wherein opposing edges of the cover are received in respective ones of the first slot and the second slot.

9. An elongated LED lighting fixture comprising:

an elongated structural frame member having a substantially channel-shaped support portion, and a mounting portion opposite the support portion and having both a first wall and a second wall angled with respect to the first wall, wherein the support portion is substantially C-shaped and includes a pair of opposed side walls and a base wall extending between the opposed side walls;

a plurality of LED light modules secured to and positioned along the first wall of the mounting portion; and

,

a cover extending along and supported by the mounting portion, the cover positioned so light emitted from the plurality of LED light modules passes through the cover and away from the mounting portion.

10. The assembly of claim 9, wherein the side walls are substantially parallel to one another and the base wall is substantially perpendicular to the side walls.

11. The assembly of claim 9, wherein the mounting portion extends between distal ends of the side walls, and wherein the mounting portion and the support portion cooperate to define a closed box section.

12. The assembly of claim 9, wherein the LED lighting fixture is substantially symmetric about a central plane.

13. The assembly of claim 9, wherein each LED lighting fixture further includes an optical assembly extending between the first wall, the second wall, and the cover.

14. The assembly of claim 9, wherein the first wall defines a first slot and the second wall defines a second slot, and wherein opposing edges of the cover are received in respective ones of the first slot and the second slot.

15. A LED light fixture assembly for use within a refrigerated display case, the light fixture assembly comprising:

an elongated first support member;

an elongated second support member spaced from and substantially parallel to the first support member; and

a plurality of elongated LED lighting fixtures coupled to and extending between the first support member and the second support member, the plurality of elongated LED lighting fixtures arranged in substantially parallel and spaced-apart relation with respect to one another, and each LED lighting fixture including;

an elongated structural frame member having a substantially channel-shaped support portion defined by a pair of opposed side walls and a base wall extending between the opposed side walls, and a mounting portion opposite the support portion, wherein the mounting portion and the support portion cooperate to define a closed box section,

a plurality of LED light modules secured to an angled first wall of the mounting portion, and

a cover extending along and supported by the mounting portion, the cover positioned so light emitted from the plurality of LED light modules passes through the cover and away from the mounting portion.

16. The LED light fixture assembly of claim 15, wherein the cover is received by a first slot formed at an end portion of the first wall and a second slot formed at an end portion of the second wall.

17. The LED light fixture assembly of claim 15, wherein the cover extends between a first slot formed at an upper end of the first wall and a second slot formed at an upper end of the side wall of the support portion.

18. The LED light fixture assembly of claim 15, wherein the refrigerated display case includes a plurality of openable doors that provide access to contents within the display case, and wherein the light fixture assembly is positioned inward of the openable doors.

19. The LED light fixture assembly of claim 18, wherein each of the openable doors is pivotally connected to the display case by a hinge member, and wherein a single LED lighting fixture is cooperatively positioned with a hinge member.
