Abstract

A lighting system for illuminating stairs and a method for installing the same. The wiring for the lighting system may be hidden from view, providing a more aesthetically pleasing appearance. Furthermore, the lighting system may be installed simultaneously with the deck itself, or afterwards. Embodiments of the present invention include stair riser lights which extend only minimally from the front surface of the stair riser. Embodiments of the present invention may focus the light towards the horizontal surface in front of the stair riser. Embodiments of the present invention may also protect the lighting system from environmental damage. Embodiments of the installation method include utilizing a jig so that the light assembly may be quickly and accurately installed.

Claims (44)

1. A light assembly for attachment to a stair riser that has a void and a front surface that is generally perpendicular to a horizontal surface, said light assembly comprising:

an opaque rear housing comprising a flange adapted to be attached to said front surface of said stair riser and a cavity attached to said flange and adapted to be situated within said void in said stair riser;

a lamp assembly situated in said cavity;

wiring passing through said cavity and connected to said lamp assembly; and

a front cover assembly attached to said flange and comprising an opaque front cover and a lens, said lens extending through a void in said front cover defined by an upper portion of said front cover and a lower portion of said front cover, such that said lens extends beyond said upper portion of said front cover and said lower portion of said front cover;

wherein:

said rear housing and front cover assembly form a protective seal around said lamp assembly; and

said front cover assembly and rear housing are adapted to direct light through said lens and toward said horizontal surface.

2. The light assembly of claim 1 further comprising:

4. The light assembly of claim 1 wherein said front cover assembly is adapted to extend less than one inch from said front surface of said stair riser.

5. The light assembly of claim 1 wherein said front cover assembly is adapted to extend less than one and one-half inches from said front surface of said stair riser.

6. The light assembly of claim 1 wherein said front cover assembly is adapted to extend less than two inches from said front surface of said stair riser.

7. The light assembly of claim 1 further comprising a grommet attached to said cavity, wherein said wiring passes through said grommet.

8. The light assembly of claim 1 wherein said lens is any one of the following: transparent, etched, frosted, textured, or tinted.

9. The light assembly of claim 1 wherein said rear housing is comprised of metal or plastic.

10. The light assembly of claim 1 wherein said front cover is comprised of metal or plastic.

11. The light assembly of claim 1 wherein said lens is comprised of glass or plastic.

12. The light assembly of claim 1 further comprising said stair riser such that said flange is attached to said front surface of said stair riser and said cavity is situated within said void in said stair riser.

13. A light assembly for attachment to a stair riser that has a void and a front surface that is generally perpendicular to a horizontal surface, said light assembly comprising:

an opaque rear housing comprising a flange adapted to be attached to said front surface of said stair riser, a seal attached to said flange, and a cavity attached to said flange and adapted to be situated within said void in said stair riser;

a lamp assembly situated in said cavity;

a grommet attached to said cavity;

wiring passing through said grommet and connected to said lamp assembly; and

a front cover assembly attached to said flange and comprising an opaque front cover and a lens, said lens extending through a void in said front cover defined by an upper portion of said front cover and a lower portion of said front cover, such that said lens extends beyond said upper portion of said front cover and said lower portion of said front cover; wherein:

said front cover assembly mates with said seal;

said rear housing, seal, and front cover assembly form a protective seal around said lamp assembly;

said front cover assembly and rear housing are adapted to direct light through said lens and toward said horizontal surface; and

said front cover assembly is adapted to extend less than two inches from said front surface of said stair riser.

14. The light assembly of claim 13 wherein said seal is an elastomer.

15. The light assembly of claim 13 wherein said rear housing is metallic.

16. The light assembly of claim 13 further comprising said stair riser such that said flange is attached to said front surface of said stair riser and said cavity is situated within said void in said stair riser.

17. The light assembly of claim 13 wherein said lens is transparent.

18. A method for attaching the light assembly of claim 13 to a stair riser that is generally perpendicular to a horizontal surface, said stair riser comprising a front surface, said attachment method comprising:

providing a jig comprising the appropriate dimensions for forming a void for receiving said light assembly;

aligning said jig in the desired orientation on the front surface of said stair riser;

removing two circular sections of material from said stair riser by aligning a removing tool with the appropriate dimensions on said jig;

removing the material between the two circular sections to create said void;

inserting said rear housing through said void in said front surface of said stair riser;
