Abstract

A housing for a light fixture is described herein. The housing can include a first housing portion having at least one first coupling feature and at least one first receiving feature, where the at least one first receiving feature is configured to receive at least one first light module at a first adjustable distance from the first housing. The housing can also include a second housing portion having at least one second coupling feature, where the at least one second coupling feature mechanically couples to the at least one first coupling feature. A position of the first housing portion relative to the second housing portion can be changed using the at least one first coupling feature and the at least one second coupling feature.

First claim

What is claimed is:

1. A light fixture, comprising:
at least one first light module;
a housing;
at least one first support member coupled to the housing; and
a frame comprising:
a first frame portion comprising at least one first frame coupling feature, at least one first housing coupling feature, and at least one first receiving feature, wherein the at least one first receiving feature mechanically couples to the at least one first light module; and
a second frame portion comprising at least one second frame coupling feature, wherein the at least one second frame coupling feature mechanically couples to the at least one first frame coupling feature of the first frame portion,

wherein a first position of a plurality of positions of the first frame portion relative to the second frame portion is changed to a second position of the plurality of positions using the at least one first frame coupling feature and the at least one second frame coupling feature,
wherein the at least one first support member suspends the first frame portion at a first distance from the housing, and
wherein the at least one first light module has a first adjustable orientation, using the at least one first receiving feature, with respect to the first frame portion.

2. The light fixture of claim 1 , wherein the second frame portion further comprises at least one second receiving feature, wherein the at least one second receiving feature couples to at least one second light module.

3. The light fixture of claim 2 , wherein the at least one second light module has a second adjustable orientation, using the at least one second receiving feature, with respect to the second frame portion.

4. The light fixture of claim 1 , wherein the at least one first light module rotates along a first axis along a length of the at least one first light module with respect to the first frame portion, wherein the at least one first light module mechanically couples to the at least one first support member of the first frame portion along the first axis.

5. The light fixture of claim 1 , wherein the first distance between the first frame portion and the housing, using the at least one first support member, is adjustable, wherein the first adjustable orientation of the at least one first light module is independent of adjusting the first distance between the first frame portion and the housing.

6. The light fixture of claim 1 , further comprising:
at least one second support member that couples to the second frame portion and the housing.

7. The light fixture of claim 1 , wherein the second frame portion moves relative to the first frame portion when the first frame portion remains fixed relative to the housing.

8. The light fixture of claim 1 , wherein the first frame portion rotates, using the at least one first support member, relative to the housing.

9. The light fixture of claim 1 , further comprising:
a third frame portion comprising the at least one third frame coupling feature and at least one third receiving feature, wherein the at least one third receiving feature mechanically couples to at least one third light module,
wherein the first frame portion and the second frame portion are part of a first frame section,
wherein the third frame portion is part of a second frame section, and
wherein the first frame section and the second frame section are movably coupled to each other using the at least one third frame coupling feature.

10. The light fixture of claim 9 , wherein the third frame portion is mechanically coupled to the housing using the at least one third support member coupled to the housing and the third frame portion.

11. The light fixture of claim 10 , wherein the third support member suspends the third frame portion from the housing at an adjustable second distance.

12. The light fixture of claim 1 , wherein the first frame portion and the second frame portion are positioned an obtuse or an acute angle relative to each other.

13. The light fixture of claim 1 , wherein the at least one first light module comprises a plurality of first light modules, wherein one of the plurality of first light modules is movable relative to the first frame portion independent of a remainder of the plurality of first light modules.

14. The light fixture of claim 1 , wherein the at least one first light module comprises a plurality of first light modules, wherein one of the plurality of first light modules is removed without affecting a performance of a remainder of the plurality of first light modules.

15. A frame for a light fixture, the frame comprising:
a first frame portion comprising at least one first housing coupling feature, at least one first frame coupling feature, and at least one first support member, wherein the at least one first housing coupling feature is configured to couple to at least one receiving feature of the light fixture, wherein the at least one first support member is configured to receive at least one first light module, wherein the at least one first receiving feature suspends the first frame at a first adjustable distance from a housing of the light fixture; and
a second frame portion comprising at least one second frame coupling feature and at least one second support member, wherein the at least one second frame coupling feature movably couples to the at least one first frame coupling feature, and wherein the at least one second support member is configured to receive at least one second light module,
wherein a position of the first frame portion relative to the second frame portion is changed using the at least one first frame coupling feature and the at least one second frame coupling feature,
wherein the at least one first light module has a first adjustable orientation with respect to the first frame using the at least one first support member, and wherein the at least one second light module has a second adjustable orientation with respect to the second frame using the at least one second support member.

16. The frame of claim 15 , wherein the second frame portion further comprises at least one second housing coupling feature, wherein the at least one second housing coupling feature is configured to receive at least one second receiving feature of the light fixture, wherein the at least one second receiving feature suspends the second frame at a second adjustable distance from the housing.

17. The frame of claim 15 , further comprising:
a third frame portion comprising at least one third frame coupling feature, wherein the at least one third frame coupling feature mechanically couples to the at least one first frame coupling feature of the first frame portion.

18. The frame of claim 17 , wherein the third frame portion further comprises at least one third support member that is configured to receive at least one third light module.

19. The frame of claim 18 , wherein the first frame portion and the second frame portion are part of a first frame section.

20. The frame of claim 19 , wherein the third frame portion is part of a second frame section that is movably coupled to the first frame section.
