Abstract

A lighting fixture is provided that includes a ceiling pan having an opening with a trim received therein. The trim includes a ring with a spring clip attached thereto. The spring clip includes first and second legs having a first end joined at an apex and second free end opposite the first end. The second free ends are fixed to the trim to bias the spring clip in a downward direction to engage a top surface of the ceiling pan and bias the trim in an upward direction toward the ceiling pan. In one embodiment, the ends of the spring clip are fixed to the trim by a screw. In another embodiment, the spring clip is a torsion spring engaging the trim and includes first and second legs with a portion extending therefrom and received in an aperture in the trim. The ends are oriented at an inclined angle with respect to the legs such that when the legs are attached to the trim, the legs are biased in a downward direction with respect to the ceiling pan. The torsion spring clip can be retrofit to the trim ring.

Claims

1. A lighting fixture comprising:

a pan having an opening and being adapted for mating with a ceiling panel;

a trim member received in said opening; and

a spring clip having first and second legs, each leg having a first end portion coupled to said trim member and a second end joined together at an apex, said end portions of said spring clip extending inwardly with respect to each other and at an incline with respect to a plane of said first and second legs, said end portions being coupled to said trim member to bias said apex of said spring clip in a downward direction with respect to said pan whereby said apex engages a top surface of said pan to couple said trim member to said pan.

2. The lighting fixture according to claim 1 wherein

said first end portion of each of said legs is fixed to said trim member with a screw.

3. The lighting fixture according to claim 2 wherein

said first end portion includes a circular-shaped member receiving the screw for fixing said first end to said trim member.

4. The lighting fixture according to claim 1 wherein

each of said legs is angled in a downward direction toward a bottom end of said trim member.

5. The lighting fixture according to claim 1 wherein

said trim member further includes a plurality of attachment points adapted to secure a plurality of spring clips to an outer surface of said trim member.

6. The lighting fixture according to claim 1 wherein

said spring clip is made of spring steel.

7. The lighting fixture of claim 1 wherein

said end portions of said legs are coupled to said trim member to fix said end portions in a horizontal plane with respect to said pan to bias said apex in said downward direction.

8. The lighting fixture of claim 7 wherein

said trim ring includes two apertures receiving a respective end portion of said first and second legs, said apertures extending in an axial direction substantially parallel to a plane of said pan and adapted for retaining said end portions under tension in a plane substantially parallel to said pan.

9. The lighting fixture of claim 8 wherein

said trim member includes two spaced apart rivets having an axial bore defining said apertures.

10. The lighting fixture of claim 1 wherein said trim member defining an annular side wall oriented substantially perpendicular to said ceiling panel, and said end portions of said legs being coupled to an outer surface of said annular side wall to tension said end portions in a direction to bias said legs in said downward direction.

11. A lighting fixture comprising:

a pan having a top surface and an opening with a downwardly extending collar surrounding said opening for directing light to a target area;

a trim ring received in said collar, said trim ring having an annular side wall complementing said collar;

a torsion spring clip coupled to said side wall, said spring clip having first and second legs coupled together at a first end to form an apex and a second end portion extending from a second end of said first and second legs, respectively, wherein said end portions are oriented at an inclined angle with respect to a plane of said first and second legs in a normal rest position and extend inwardly with respect to said legs and at an inclined angle with respect to each other, said end portions being coupled to said trim ring under tension to form a downward biasing force to said first and second legs to engage said top surface of said pan to retain said trim ring in said opening.

12. The lighting fixture according to claim 11 wherein

said trim ring includes at least one cross baffle.

13. The lighting fixture according to claim 12 wherein

said side wall of said trim ring includes a rivet having a bore.

14. The lighting fixture according to claim 13 wherein

said end portions of said first and second legs of said torsion spring clip are mounted in a bore of a respective rivet substantially parallel to each other.

15. The lighting fixture according to claim 11 wherein

said end portions of said first and second legs of said torsion spring clip are mounted into a respective body of said trim ring, each said body having an axial bore extending substantially parallel to a plane of said pan whereby said end portions are held under tension to form said biasing force to bias said apex in a downward direction.

16. The lighting fixture of claim 11 wherein

said end portions of said legs are coupled to said annular side wall of said trim ring to extend in a plane substantially parallel to said top surface of said pan under tension to bias said legs in said downward direction.

17. The lighting fixture of claim 16 wherein

said annular wall of said trim ring has two apertures extending therethrough, and where said end portions of said spring clip are received in a respective aperture under tension to retain said end portions substantially perpendicular to a plane of said side wall.

18. The lighting fixture of claim 17 wherein

said side wall has a rivet extending through each of said apertures and having an axial bore receiving said end portions.

19. A lighting fixture comprising:

a pan having a top surface, a bottom surface and an opening extending between said top surface and bottom surface, said pan adapted for mating with a ceiling panel and for supporting a lighting assembly;

a trim member having a side wall with a dimension for being received in said opening in said pan and an outwardly extending flange at a bottom edge of said side wall, said side wall having a plurality of supports having an axial passage extending through said side wall; and

at least two spring members coupled to said supports of said trim member for coupling said trim member to said pan;

each said spring member having a first leg with a first end portion and a second leg having a first end portion, said first and second legs having a second end joined together at an apex, said end portions extending inwardly with respect to each other and at an incline with respect to a plane of said first and second legs, each said end portion being received in a respective axial bore under tension to lie in a plane substantially perpendicular to said side wall of said trim ring to form a biasing force to bias said legs in a downward direction whereby said second ends engage said top surface of said pan and couple said trim member to said pan.

20. The lighting fixture according to claim 19 wherein

the first and second supports are coplanar.

21. The lighting fixture according to claim 19 wherein

each of said first and second legs extend substantially tangentially from said trim member.

22. The lighting fixture of claim 19 wherein

said trim member includes a plurality of rivets extending through said side wall, said rivets having an axial bore defining said supports.

23. The lighting fixture of claim 22 wherein

said trim member includes a plurality of baffles secured to said side wall by said rivets.
