Abstract

An assembly for connecting and holding a photocontrol with respect to a light fixture. The assembly includes a support member and a photocontrol receptacle over and secured with respect to the support member. The support member is on an exterior surface of a light-fixture housing at an opening formed in the housing. The photocontrol receptacle is rotatable about the support member for angular photocontrol adjustment on the light fixture. The support member is fixed with respect to the exterior surface of the light-fixture housing. The receptacle has an engagement portion rotatably engaging the support member, thereby holding the receptacle with respect to the light-fixture housing while permitting rotation of the receptacle with respect thereto. Another aspect is a related method for connecting and holding a photocontrol with respect to a light fixture.

First claim

The invention claimed is:

1. An assembly for connecting and holding a photocontrol with respect to a light fixture, the assembly comprising:
a support member on an exterior surface of a light-fixture housing at an opening into the housing; and
a receptacle with slots for insertion of photocontrol conductors, the receptacle being secured with respect to the support member such that the support member is between a light-fixture exterior surface about the opening and the receptacle which is rotatable about the support member for angular photocontrol adjustment on the light fixture.

2. The assembly of claim 1 wherein:
the support member has a peripheral region beyond the opening; and
the receptacle has (a) a body portion defining the slots and supporting electrical connections for the photocontrol and (b) an engagement portion extending from the body portion and rotatably engaging the support member, thereby holding the receptacle with respect to the light-fixture housing while permitting rotation of the receptacle with respect thereto.

3. The assembly of claim 2 wherein the engagement portion extends over and radially beyond the peripheral region of the support member.

4. The assembly of claim 2 wherein the engagement portion has a peripheral outer surface including gripping features thereon to facilitate manual rotation of the engagement portion of the receptacle about the peripheral region of the support member.

5. An assembly for connecting and holding a photocontrol with respect to a light fixture, the assembly comprising:
a support member on an exterior surface of a light-fixture housing at an opening formed in the housing, the support member having a peripheral region beyond the opening, the peripheral region of the support member including a peripheral edge portion spaced from the exterior surface of the light-fixture housing; and
a photocontrol receptacle over and secured with respect to the support member and rotatable thereabout for angular photocontrol adjustment on the light fixture, the receptacle having (a) a body portion supporting photocontrol electrical connections and (b) an engagement portion extending from the body portion and being in snap-engagement with the peripheral edge portion of the support member, thereby holding the receptacle with respect to the light-fixture housing while permitting rotation of the receptacle with respect thereto.

6. The assembly of claim 5 wherein:
the peripheral edge portion of the support member is annular and unbroken; and
the engagement portion of the receptacle is annular and unbroken.

7. The assembly of claim 6 wherein the engagement portion of the receptacle has an inner surface defining a groove which receives the peripheral edge portion of the support member.

8. The assembly of claim 7 wherein the snap-engagement is substantially water-tight.

9. The assembly of claim 5 wherein the peripheral edge portion of the support member and the engagement portion of the receptacle have interfering features configured and positioned to limit rotation of the receptacle with respect to the support structure beyond 360°.

10. The assembly of claim 5 wherein the support member and the engagement portion of the receptacle are configured for non-free rotation, thereby keeping the photocontrol in a selected angular orientation with respect to the light fixture.

11. The assembly of claim 10 wherein:
the support member includes an upwardly projecting wall; and
the receptacle has a downward-facing surface in frictional engagement with the upwardly projecting wall of the support member.

12. The assembly of claim 11 wherein:
the upwardly projecting wall of the support member terminates with an upper toothed edge; and
the downward-facing surface of the receptacle has a toothed surface portion engaging the toothed upper edge of the support member creating resistance to unintentional rotation of the receptacle with respect to the support member.

13. The assembly of claim 5 wherein the support member is a separate piece fixedly attached to the exterior surface of the light-fixture housing.

14. The assembly of claim 13 further including a seal between the support member and the exterior surface of the light-fixture housing.

15. The assembly of claim 5 wherein the engagement portion of the receptacle is a separate piece secured to the body portion of the receptacle.

16. The assembly of claim 1 wherein the support member is a separate piece fixedly attached to the exterior surface of the light-fixture housing.

17. The assembly of claim 16 further including a seal between the support member and the exterior surface of the light-fixture housing.

18. A method for connecting and holding a photocontrol with respect to a light fixture, the method comprising:
providing a support member on an exterior surface of a light-fixture housing at an opening into the housing;
positioning over the support member a receptacle with slots for insertion of photocontrol conductors;
securing the receptacle with respect to the support member such that the support member is between the receptacle and the light-fixture exterior surface about the opening;
connecting the photocontrol to the receptacle by inserting the photocontrol conductors into the slots of the receptacle; and
rotating the secured receptacle about the support structure for angular photocontrol adjustment on the light fixture.

19. The method of claim 18 wherein the rotating step is after the connecting step.

20. The method of claim 18 wherein:
the support member has a peripheral region beyond the opening; and
the receptacle has (a) a body portion defining the slots and supporting electrical connections for the photocontrol and (b) an engagement portion extending from the body portion and rotatably engaging the support member, thereby holding the receptacle with respect to the light-fixture housing while permitting rotation of the receptacle with respect thereto.

21. The method of claim 20 wherein:
the support member is a separate piece from the light-fixture housing; and
the step of providing the support member includes the further step of fixedly attaching the support member to the exterior surface of the light-fixture housing.

22. The method of claim 21 comprising the further step of sealing the attachment between the support member and the exterior surface of the light-fixture housing.

23. The method of claim 18 wherein:
the engagement and body portions of the receptacle are separate pieces; and
the step of positioning the photocontrol receptacle over the support member includes the further step of joining the body portion with the engagement portion of the receptacle.

24. The method of claim 23 wherein:
the support member is a separate piece from the light-fixture housing; and
the step of providing the support member includes the further step of fixedly attaching the support member to the exterior surface of the light-fixture housing.

25. The method of claim 24 comprising the further step of sealing the attachment between the support member and the exterior surface of the light-fixture housing.
