| Abstract: |
In one embodiment, the fiber optic lighting system includes a centrally disposed light source and a plurality of fiber optic cables running from that central light source to a respective plurality of remote locations on the boat. The light source is mounted in a first transparent tube having open axial ends. A second transparent tube is concentrically disposed in close proximity to, but spaced from the first transparent tube. The first tube is removably mounted in the second tube. An internally mirrored chamber circumferentially surrounds the first and second tubes. The chamber is sealed at each axial end. The proximal ends of each fiber optic cable extends into the mirrored chamber and is in substantial engagement with the outer surface of the second tube. A light fixture is associated with each distal end of the optic fiber cables. Each light fixture includes a truncated, inverted cone with the distal end of the fiber mounted proximate the truncated vertex thereof. The outer surface of the inverted cone is mirrored. A second mirrored cone is coaxially disposed above the inverted cone. The second cone is held in place by a dome which has a mirrored inner surface. A housing supports the dome and the second cone. The housing includes light transmissive sides extending from the base of the inverted cone to the edge of the dome.

What we claim is:
1. A fiber optic lighting system for boats comprising:
- a light source centrally disposed in a first transparent tube, said first transparent tube having open axial ends;
- a second transparent tube concentrically disposed in close proximity but spaced from said first transparent tube;
- means for removably mounting said first transparent tube from said second transparent tube;
- an elongated internally mirrored chamber defining a surface circumferentially surrounding said first and second transparent tubes and having a seal at each axial end thereof extending from said second transparent tube to at least the internally mirrored surface of said chamber;
- a plurality of flexible, elongated optical fiber means for carrying light emitted by said light source, each fiber means having a proximal end in substantial engagement with an outer surface of said second transparent tube, a body portion adapted to be run to remote locations distant from said light source on said boat and a distal end remote from said proximal end that emits light carried by the fiber means;
- a plurality of light fixtures, a respective light fixture corresponding to a respective fiber means and disposed at the distal end thereof, each light fixture including;
- a truncated inverted cone with said distal end of said fiber means mounted proximate the truncated vertex of said inverted cone, said distal end launching light coaxially from said truncated vertex, the outer surface of said inverted cone being mirrored;
- a second mirrored cone defining a surface coaxially disposed above said inverted cone, the vertex of said second cone pointing towards said distal end such that emitted light therefrom is reflected off the mirrored surface of said second cone;
- a dome at the base of said second cone having a concave, mirrored inner surface such that said emitted light and the reflected light from said second cone is reflected from said concave surface and is directed to the mirrored outer surface of said inverted cone; and,
- a housing supporting said inverted cone and said dome and receiving a distal end section of said fiber means, said housing having a light transmissive portion extending from a base section of said inverted cone to a edge section of said dome such that light emitted from said fiber means and reflected from the mirrored surfaces is transmitted from said light fixture.
