Patent ID: 7758219

Claim:
A stern light system for a boat, comprising: a base mounted to or within a boat structure or component, an integral socket recessed into the base, said recessed socket directly coupling to a proximal end rod portion of the removable light conduit, said direct coupling comprising a slip-fit diameter of the recessed socket to the diameter of said rod, an enclosing of a proximal portion of said rod and a socket recess depth into the base such that a minimal gap is formed between the socket proximal end and the light source; a connection to an electrical power source; a combination driver device and light source, said combination enclosed within the base but external to the recessed socket of the base, the light driver device operably connected to the electrical power source and comprising voltage conversion, low power dissipation and accurate control of light source current, the light source operably connected to the light driver and abutting the proximal end of the base recessed socket with a minimal gap, the light source operable to project light across said minimal gap and into the light conduit rod proximal end, when said light conduit rod is installed in the recessed base socket a removable light conduit, having the structure of a monolithic non-tapering cylindrical solid rod, the rod material comprising transparency and a higher refractive index than the surrounding media, a proximal end rod portion directly coupling with the recessed socket of the base, the direct coupling comprising a slip-fit diameter of the rod to the diameter of the recessed socket of the base, a proximal portion for enclosure by said socket and a light coupling surface area, the light coupling surface area consisting of the proximal end surface area of the rod, and a middle portion whose combination of structure and material make it operable to efficiently conduit and confine the conduit light to the distal end and maintain structural integrity at a length of at least forty eight inches; and a mechanism to redirect and emit the light conducted within the light conduit rod out of the distal end in the in the desired emission pattern, said mechanism encompassed within the distal end structure, said structure a continuity of the non-tapering cylindrical rod of the light conduit, said mechanism a reflective surface near the distal end, said reflective surface having an angle-of-incidence to the conduit light operable to redirect and emit conduit light largely perpendicularly and a shape operable to emit light in the desired emission pattern around the distal end.
