Abstract

A lighting arrangement can include a luminaire and a first plurality of spring arms. The luminaire can include a housing assembly and a light emitter portion at least partially enclosing the light emitter portion. The first plurality of spring arms can each be engageable with the luminaire and extend from a respective base end to a respective distal end. The base ends can be positioned closer to the housing assembly than the distal ends. Each of the first plurality of spring arms can extend vertically upward and away from the housing assembly along the axis such that the base ends are vertically lower than the distal ends. Each of the first plurality of spring arms can extend along a torturous path and be cantilevered off of the housing assembly.

Claims

1. A lighting arrangement comprising:

a luminaire having a housing assembly and a light emitter portion, said housing assembly at least partially enclosing said light emitter portion, said luminaire extending vertically along and substantially centered on an axis; and

a first plurality of spring arms each engageable with said luminaire, each of said first plurality of spring arms extending from a respective base end to a respective distal end, said base ends of said first plurality of spring arms positioned closer to said housing assembly than said distal ends, wherein each of said first plurality of spring arms extends vertically upward and away from said housing assembly along said axis such that said base ends are vertically lower than said distal ends, wherein each of said first plurality of spring arms extend along a torturous path having a plurality of turns defined between said base end and said distal end, and wherein each of said first plurality of spring arms are cantilevered off of said housing assembly.

2. The lighting arrangement of claim 1 wherein at least one of said first plurality of spring arms extends initially from said base end toward said axis in a direction transverse to said axis, then extends through a first turn and away from said axis to define a receiving portion, and then extends through a second turn and back towards said axis such that said distal end is closer to said axis than said base end.

3. The lighting arrangement of claim 1 wherein at least one of said first plurality of spring arms defines a barb at said distal end whereby said at least one of said first plurality of spring arms extends from said distal end in a direction that is toward said axis and also upward.

4. The lighting arrangement of claim 1 wherein at least one of said first plurality of spring arms extends between said base end and said distal end and also extends between said base end and a second distal end spaced from said distal end about said axis.

5. The lighting arrangement of claim 4 wherein said at least one of said first plurality of spring arms extends initially from said base end away said axis in a direction transverse to said axis, extends through a first turn, and bifurcates to extend along respective mirrored paths to said distal end and said second distal end.

6. The lighting arrangement of claim 4 wherein said at least one of said first plurality of spring arms further comprises:

a base portion defining said base end;

a plate portion adjacent to said base portion; and

first and second arm members projection from said plate portion, said first arm member defining said distal end and said second arm member defining said second distal end.

7. The lighting arrangement of claim 6 wherein said plate portion is arcuate in plane transverse to said axis.

8. The lighting arrangement of claim 1 wherein said housing assembly further comprises an upwardly-facing surface and a plurality of different spring arm mounting patterns arranged on said upwardly-facing surface, each of said plurality of different spring arm mounting patterns including at least two mounting locations and each of said at least two mounting locations configured to receive one of said first plurality of spring arms.

9. The lighting arrangement of claim 8 wherein at least one of said plurality of different spring arm mounting patterns is defined at least in part by one or more apertures.

10. The lighting arrangement of claim 8 wherein at least one of said plurality of different spring arm mounting patterns includes more than two mounting locations and said mounting locations are equally spaced from one another about said axis.

11. The lighting arrangement of claim 8 wherein at least one of said plurality of different spring arm mounting patterns includes a first spring arm mounting pattern having two mounting locations equally spaced from one another about said axis and a second spring arm mounting pattern having more than two mounting locations equally spaced from one another about said axis.

12. The lighting arrangement of claim 1 wherein said first plurality of spring arms further comprises:

a first group of spring arms having a first configuration; and

a second group of spring arms having a second configuration, said first configuration and said second configuration different from one another.

13. The lighting arrangement of claim 1 further comprising:

a mounting ring having an aperture wherein said first plurality of spring arms extend through said aperture and interconnect said luminaire with said mounting ring.

14. The lighting arrangement of claim 13 wherein said first plurality of spring arms are elastically deformed during movement through said aperture.

15. The lighting arrangement of claim 13 further comprising:

a second plurality of spring arms each engageable with said mounting ring, each of said second plurality of spring arms extending from a respective base end to a respective distal end, said base ends of said second plurality of spring arms positioned closer to said mounting ring than said distal ends, wherein each of said second plurality of spring arms extends vertically upward and away from said mounting ring such that said base ends are vertically lower than said distal ends, wherein each of said second plurality of spring arms extend along a torturous path having a plurality of turns defined between said base end and said distal end, wherein each of said second plurality of springs arm are cantilevered off of said mounting ring.

16. The lighting arrangement of claim 15 wherein said first plurality of spring arms and said second plurality of spring arms are differently shaped from one another.

17. The lighting arrangement of claim 16 wherein each of said first plurality of spring arms extends initially from said base end toward said axis in a direction transverse to said axis, extends through a first turn and away from said axis to define a receiving portion that receives an edge of said aperture of said mounting ring, and extends through a second turn and back towards said axis such that said distal end is closer to said axis than said base end.

18. The lighting arrangement of claim 17 wherein each of said second plurality of spring arms defines a barb at said distal end whereby said each of said second plurality of spring arms extends from said distal end in a direction that is toward said axis and also upward.

19. The lighting arrangement of claim 17 each of said second plurality of spring arms extends between said base end and said distal end and also extends between said base end and a second distal end spaced from said distal end about said axis.

20. The lighting arrangement of claim 19 wherein each one of said second plurality of spring arms further comprises:

a base portion defining said base end;

a plate portion adjacent to said base portion; and

first and second arm members projection from said plate portion, said first arm member defining said distal end and said second arm member defining said second distal end.
