Abstract

Abstract Light rays emanating from a light source within a recess in one end of a solid transparent elongate member are concentrated within and longitudinally conducted along a first portion thereof having a smooth, preferably polished outer surface, and then radiated from the roughened outer surface of a second portion extending longitudinally from the first portion, to provide directionally controlled selective illumination remote from the light source. Clamp means may be provided to attach the elongate member to the side of a liquid containing vessel such as a swimming pool or aquarium to selectively position the second portion of the elongate member beneath the surface of the liquid to safely illuminate the surrounding area.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 165 words
Illuminating means comprising: a first light source; and a generally solid integral elongate member formed from transparent material and having a selectively formed exterior surface and a first end having a first recess therein, said light source being selectively disposed within said first recess; said elongate member having a first portion having a first selective length and a second portion having a second selective length, said first portion extending longitudinally from said first end and having a smooth exterior surface, said second portion extending longitudinally from the end of said first portion and having a roughened exterior surface, said second portion being disposed generally remote from both ends of said elongate member whereby upon the energization of said first light source within said first recess, the light rays emanating therefrom are concentrated within and longitudinally conducted along said first portion of said elongate member and radiated from the roughened exterior surface of said second portion of said elongate member to illuminate the surrounding area thereat.
Claim 2
Dependent Claim 165 words
Illuminating means comprising: a first light source; and a generally solid integral elongate member formed from transparent material and having a selectively formed exterior surface and a first end having a first recess therein, said light source being selectively disposed within said first recess; said elongate member having a first portion having a first selective length and a second portion having a second selective length, said first portion extending longitudinally from said first end and having a smooth exterior surface, said second portion extending longitudinally from the end of said first portion and having a roughened exterior surface, said second portion being disposed generally remote from both ends of said elongate member whereby upon the energization of said first light source within said first recess, the light rays emanating therefrom are concentrated within and longitudinally conducted along said first portion of said elongate member and radiated from the roughened exterior surface of said second portion of said elongate member to illuminate the surrounding area thereat.
Claim 3
Dependent Claim 38 words
Illuminating means as defined in claim 1 wherein said elongate member has a second recess in the end thereof opposite said first end, and said illuminating means further comprises a second light source disposed in said second recess.
Claim 4
Dependent Claim 174 words
Illuminating means comprising: a first light source; a generally solid integral elongate member formed from transparent material and having a selectively formed exterior surface and a first end having a first recess therein, said light source being selectively disposed within said first recess; and means removably attached to said elongate member adjacent said first end thereof for sealing the opening formed by said first recess thereat, said elongate member having a first portion having a first selective length and a second portion having a second selective length, said first portion extending longitudinally from said first end and having a smooth exterior surface, said second portion extending longitudinally from the end of said first portion and having a roughened exterior surface, whereby upon the energization of said first light source disposed within said first recess, the light rays emanating therefrom are concentrated within and longitudinally conducted along said first portion of said elongate member and radiated from the roughened exterior surface of said second portion of said elongate member to illuminate the surrounding area thereat.
Claim 5
Dependent Claim 174 words
Illuminating means comprising: a first light source; a generally solid integral elongate member formed from transparent material and having a selectively formed exterior surface and a first end having a first recess therein, said light source being selectively disposed within said first recess; and means removably attached to said elongate member adjacent said first end thereof for sealing the opening formed by said first recess thereat, said elongate member having a first portion having a first selective length and a second portion having a second selective length, said first portion extending longitudinally from said first end and having a smooth exterior surface, said second portion extending longitudinally from the end of said first portion and having a roughened exterior surface, whereby upon the energization of said first light source disposed within said first recess, the light rays emanating therefrom are concentrated within and longitudinally conducted along said first portion of said elongate member and radiated from the roughened exterior surface of said second portion of said elongate member to illuminate the surrounding area thereat.
Claim 6
Dependent Claim 56 words
Illuminating means as defined in claim 3 wherein said means is a resilient member having a first portion extending partially into said first recess, said first portion having a generally concave reflective surface facing said first light source for redirectIng the light rays impinging thereon in a path along the longitudinal axis of said elongate member.
