Light fixture support assembly

1. A light-fixture support assembly for securing a light fixture to a fixed surface, the assembly comprising a fixture-support member and a surface-attachment member, wherein:

the fixture-support member has walls defining a compartment and extends between a distal end secured to the light fixture and an opposite proximal end engaging the surface-attachment member, the proximal end including an outwardly-extending substantially-horizontal neck which supports a flange portion thereabout; and

the surface-attachment member has an at least partially-open top, a fixed-surface end attachable to the fixed surface and a neck-engaging end defining a support opening dimensioned wider than the neck and narrower than the flange portion, the open top receiving the neck within the support opening thereby securing the fixture-support member to the surface-attachment member.

2. The light-fixture support assembly of claim 1 wherein:

the proximal end of the fixture-support member defines a first opening for communication with the surface-attachment member; and

the neck defines a channel in communication with the first opening.

3. The light-fixture support assembly of claim 1 wherein the neck and flange portion are entirely within the surface-attachment member when the neck is inserted into the support opening.

4. The light-fixture support assembly of claim 1 wherein the neck is integral with the fixture-support member.

5. The light-fixture support assembly of claim 1 wherein:

the fixture-support member includes a distal-end wall which defines a second opening for communication with the light fixture; and

the light fixture defines a passage in communication with the second opening of the fixture-support member.

6. The light-fixture support assembly of claim 5 wherein the fixture-support member is connected to the light fixture via a clamp.

7. The light-fixture support assembly of claim 6 wherein the clamp is U-shaped such that it extends through the light-fixture passage and the second opening to sandwich a light-fixture wall and the fixture-support-member distal-end wall between U-shaped clamp walls.

8. The light-fixture support assembly of claim 5 further including a gasket between the light fixture and the fixture-support member.

9. The light-fixture support assembly of claim 1 wherein the compartment of the fixture-support member is at least partially open on a top side of the fixture-support member, the assembly further including a cover piece sized to cover the at least partially open top side of the fixture-support member and releasably connected thereto.

10. The light-fixture support assembly of claim 9 wherein the connection between the cover piece and the fixture-support member is a weather-tight seal.

11. The light-fixture support assembly of claim 10 wherein the cover piece is releasably attached via fasteners.

12. The light-fixture support assembly of claim 9 wherein the surface-attachment member includes two opposite side walls connected by a bottom wall, the walls defining the surface-attachment-member compartment.

13. The light-fixture support assembly of claim 12 wherein the surface-attachment member is of one-piece construction.

14. The light-fixture support assembly of claim 1 further including a locking member which is releasably connected to the surface-attachment member over the neck when the neck is inserted into the support opening.

15. The light-fixture support assembly of claim 12 further including a surface-attachment member cover piece sized to cover the at least partially open top side of the surface-attachment member and releasably connected thereto.

16. The light-fixture support assembly of claim 15 wherein the connection between the surface-attachment member and its cover piece is a weather-tight seal.

17. The light-fixture support assembly of claim 9 wherein the fixture-support member further includes mounting points extending from the walls into the compartment.
