Protecting lighting devices from damage
Embodiments of the present invention relate generally to lighting systems for outdoor deck areas, for lighting purposes as well as decorative purposes, and more particularly to several embodiments of a stair riser light and a method for installing a stair riser light.
Outdoor deck areas are very popular as they add to the beauty of the home as well as provide a functional place to enjoy the outdoors. However, many decks do not have a sufficient lighting such that they can be enjoyed during the night time as well as the day time. Furthermore, the decks that currently employ lighting systems must run the wiring on the surface of the posts, railings, and deck surface, providing a look that is not aesthetically pleasing. Occasionally the wires are hidden by a conduit, but these materials are still not aesthetically pleasing. Also, current lighting systems mount on to the surface of deck materials and thus subject the deck users to various hazards such as catching their feet or clothing on the light assemblies.
Exemplary embodiments of the present invention provide a lighting system for an outdoor deck area that provides sufficient lighting while at the same time adding to the aesthetic value of the area. Therefore, embodiments of the present invention may substantially hide the wires from view and incorporate the light housings into the deck materials.
Embodiments of the present invention provide a lighting system that may be built specifically for the deck including the deck surface, railings, and posts to provide a total deck experience. Also, the deck may not need to be torn up and rearranged to put in the lighting system. The deck may be manufactured to allow the easy installation of the lighting system.
The lighting system does not have to be tailor-made for every home, but can be manufactured at a high production rate and can be installed at existing homes or businesses. Also, the embodiments do not need to be installed by a specialized carpenter, but instead can be installed by the homeowner. In this way, cost is minimized.
Embodiments of the present invention may protect the lighting assembly from environmental damage, including but not limited to water damage and insect damage.
Embodiments of the present invention include stair riser lights which are mounted within the vertical face of the stair riser such that the light assembly extends only minimally from the stair riser surface, providing a look that is both aesthetically pleasing and safe for the deck users. Furthermore, embodiments of the present invention may focus the light so that, rather than shining in all directions, the light is directed to illuminate the stair surface beneath the riser.
In addition to the novel features and advantages mentioned above, other benefits will be readily apparent from the following descriptions of the drawings and exemplary embodiments.

Exemplary embodiments of the present invention are directed to the figures described herein.
FIG. 1A is front view of an exemplary embodiment of a front plate 101. A horizontal void 102 runs down the center of the front plate 101. Cross-section 1B runs vertically down the center of the front plate 101 and through the horizontal void 102.
FIG. 1B is a cross-sectional view of a front plate or cover 101. The horizontal void 102 is shown as the un-shaded area in the center of the cross-section 1B. The front cover 101 has an upper portion 101A and a lower portion 101B that define the void 102. Also, in this example, a convex portion 101C of front cover 101 extends up from upper portion 101A, and a concave portion 101D of front cover 101 extends down from lower portion 101B. In one embodiment, a front cover 101 may be opaque and comprised of metal or plastic.
FIG. 1C is an exploded view of an exemplary embodiment of a front plate or cover assembly 100. The lens 103 fits within the horizontal void 102 within the front plate or cover 101. In one embodiment, lens 103 may be any one of the following: transparent, etched, frosted, textured, or tinted. Also, an example of lens 103 may be plastic or glass.
FIG. 2 is an exploded view of an example of a rear housing assembly 200. In one embodiment, the rear housing 201 may be opaque and comprised of metal or plastic. The rear housing 201 includes a flange 205 and a cavity 206. The seal 202 fits within the rear housing 201. A grommet 203 also fits within the rear housing 201 for allowing the passage of wiring. In addition, the lamp assembly 204 attaches to the rear housing 201. The seal 202 and grommet 203 may protect the lamp assembly 204 from damage, including but not limited to environmental, water, and/or insect damage.
FIG. 3 is an exploded view of an exemplary embodiment of a stair riser light assembly 300. The front plate assembly 100 attaches to the flange 205 of the rear housing assembly 200. The seal 202 may mate with the front plate assembly 100 to protect the lamp assembly 204 from damage, including but not limited to environmental, water, and insect damage. In one example, the seal 202 may be an elastomer.
FIG. 4 is an exploded view of an exemplary embodiment of a front plate assembly 100, rear housing assembly 200, and a stair riser 400. The deck and stair risers may be made of well known material, such as, but not limited to, wood, plastic, wood composite, and/or metal. The cavity 206 fits within the void 402 in the stair riser 400. The flange 205 mounts against the front surface of the stair riser 400. The wiring 401 passes through a grommet in the cavity 206 to connect to the lamp assembly. The front cover assembly 100 attaches to the rear housing assembly 200 such that the front cover assembly 100 extends only minimally from the front surface of the stair riser 400. In one example, the front cover assembly 100 is adapted to extend less than one inch from the front surface of the stair riser 400. In another example, the front cover assembly 100 is adapted to extend less than one and one-half inches from the front surface of the stair riser 400. In still another example, the front cover assembly 100 is adapted to extend less than two inches from the front surface of the stair riser 400.
FIG. 5 is a storyboard view of the method for installing a stair riser light assembly. The method comprises three main steps: A, B, and C. In step A, a jig 501 is properly aligned on the front surface of the stair riser 400. In step B, two circular sections of material 502 are removed from the stair riser 400. In step C, the remaining material 503 between the two circular sections 502 is removed to create the void 402.
Any embodiment of the present invention may include any of the optional or preferred features of the other embodiments of the present invention. The exemplary embodiments herein disclosed are not intended to be exhaustive or to unnecessarily limit the scope of the invention. The exemplary embodiments were chosen and described in order to explain the principles of the present invention so that others skilled in the art may practice the invention.
