Abstract

A lighting assembly is described, having an elastomeric, cylindrical ring with one or more grooves along its inner surface for engaging various components within an outdoor light assembly. For example, the elastomeric ring can engage with a disc-shaped lens, a light bulb, and/or various areas of the housing of the light assembly.

Claims

1. A light assembly comprising:

an outer light assembly housing comprising a housing base and a housing top;

said housing top being connected to a top of said housing base;

an elastomeric ring disposed within the outer light assembly housing and engaging said outer light assembly housing;

said elastomeric ring having a tubular shape with an inner surface forming a passage therethrough;

said elastomeric ring having a plurality of lateral grooves located in said passage;

said plurality of lateral grooves including a first groove extending around said inner surface; and

,

a light bulb having an outer flange disposed within said first groove of said elastomeric ring, such that said elastomeric ring maintains a position of said light bulb relative to said outer light assembly housing.

2. The light assembly of claim 1, further comprising a lens engaged within a second groove of said elastomeric ring and above said light bulb.

3. The light assembly of claim 1, further comprising a support ring having a plurality of finger elements that each extend vertically within vertical channels of said elastomeric ring.

4. The light assembly of claim 1, wherein said elastomeric ring has a protrusion extending around an outer surface of said elastomeric ring.

5. The light assembly of claim 1, further comprising a lens positioned within a recess along a top of said elastomeric ring.

6. The light assembly of claim 1, wherein the elastomeric ring is composed of a first ring and a second, separate elastomeric ring, and wherein said first elastomeric ring is disposed around said second, separate elastomeric ring.

7. A light assembly comprising:

an outer light assembly housing comprising a housing base and a housing top;

said housing top being connected to a top of said housing base and having an opening configured to allow light to shine therethrough;

an elastomeric ring disposed within the outer light assembly housing;

said elastomeric ring having a plurality of lateral grooves located within a passage of said elastomeric ring; and

,

a light bulb having an outer periphery positioned in one of said plurality of lateral grooves of said elastomeric ring such that said elastomeric ring maintains a position of said light bulb relative to said housing base and said housing top.

8. The light assembly of claim 7, further comprising a lens disposed within one of said plurality of lateral grooves of said elastomeric ring.

9. The light assembly of claim 7, further comprising a support ring having a plurality of finger elements that each extend vertically within vertical channels of said elastomeric ring.

10. The light assembly of claim 7, wherein said elastomeric ring has a protrusion extending around an outer surface of said elastomeric ring.

11. The light assembly of claim 7, further comprising a lens disposed within one of said plurality of lateral grooves of said elastomeric ring and being located above said light bulb.

12. A light assembly comprising:

a housing base having a cavity therein;

a housing top having a tubular shape forming a bottom opening engaging a top of said housing base and a top opening configured to allow light to shine therethrough;

an elastomeric tube disposed within the outer light assembly housing and contacting an interior of said housing base and an interior of said housing top;

said elastomeric tube having an inner surface forming a passage therethrough with a plurality of horizontal grooves;

said plurality of horizontal grooves having a first groove extending around said inner surface; and

,

a light bulb having an outer flange disposed within said first groove of said elastomeric tube;

wherein said elastomeric tube maintains a position of said light bulb within and relative to said housing base.

13. The light assembly of claim 12, further comprising a lens engaged within a second groove of said elastomeric ring and above said light bulb.

14. The light assembly of claim 12, further comprising a support ring having a plurality of finger elements that each extend vertically within vertical channels of said elastomeric ring.

15. The light assembly of claim 12, wherein said elastomeric ring has a protrusion extending around an outer surface of said elastomeric ring.

16. The light assembly of claim 12, further comprising a lens positioned within a recess along a top of said elastomeric ring.

17. The light assembly of claim 12, wherein the elastomeric ring is composed of a first ring and a second, separate elastomeric ring.

18. A light assembly comprising:

an outer light assembly housing comprising a housing base and a housing top;

said housing top being connected to a top of said housing base;

an elastomeric ring disposed within the outer light assembly housing and engaging said outer light assembly housing;

said elastomeric ring having a tubular shape with an inner surface forming a passage therethrough;

said elastomeric ring having a first groove extending around said inner surface;

a light bulb having an outer flange disposed within said first groove of said elastomeric ring; and

,

a lens engaged within a second groove of said elastomeric ring and above said light bulb.

19. A light assembly comprising:

an outer light assembly housing comprising a housing base and a housing top;

said housing top being connected to a top of said housing base;

an elastomeric ring disposed within the outer light assembly housing and engaging said outer light assembly housing;

said elastomeric ring having a tubular shape with an inner surface forming a passage therethrough;

said elastomeric ring having a first groove extending around said inner surface;

a light bulb having an outer flange disposed within said first groove of said elastomeric ring; and

,

comprising a support ring having a plurality of finger elements that each extend vertically within vertical channels of said elastomeric ring.
