Abstract
This invention discloses a fiber optic lens holder and lamp assembly for use in lighting systems used beneath carpets and other types of floor or wall coverings. The lens assembly includes a housing having a cavity for receiving the lamp, an optically transparent web portion adjacent to the lamp cavity, and an annular end portion for receiving a bundle of optical fibers. The optical fibers are fused together at one end, preferably in a point, and are secured in the housing at the other within the annular section. The lens and lamp assembly is installed, typically with a flat cable conductor assembly, on the floor prior to laying of the carpet. Holes are cut in the carpet corresponding with the locations for the fiber optic bundles. The fiber optic bundles are passed through these holes as the carpet is laid down. After the carpet is laid down, the fused end of each bundle is cut off, freeing the fiber ends from fusion with each other so that the fiber ends are flush with the surface of the carpet. Thus, the invention provides an unobtrusive and durable means for providing emergency or decorative floor illumination.
