Extruded track lighting system

A system of tracked lights, comprising:

• a support rail having a pair of parallel spaced cylindrical conductors separated by an insulating member, said conductors being at least partially exposed and accessible from an exterior location;
• a bracket having a pair of conductive clamp legs with concave portions that conform to an exposed portion of said conductors adapted to clamp to said conductors, said bracket having two pairs of aligned apertures said first pair being on an end of said bracket opposite said concave portions and said second pair being intermediate said first pair and said concave portions;
• a spacer positioned between said clamp legs and having a threaded bore aligned with said first pair of apertures;
• a plurality of fasteners having threaded shafts adapted to engage said threaded bore, two of said fasteners being inserted through said second pair of apertures to clamp inner surfaces of said clamp legs to said spacer;
• and
• a lamp mounting fixture positioned between said clamp legs and having conductive elements in communication with said clamp legs and mounted with two of said fasteners to rotate about an axis through said first pair of apertures,
• wherein said bracket clamps to said support rail and rotation of said bracket about said support rail is constrained therefore, and wherein electricity from said conductors may conduct directly through said bracket clamp legs to said fixture conductive members to provide power to an associated lighting fixture.

A kit for a track lighting system, comprising:

• a flexible extruded member having a pair of elongated grooves formed on opposing sides of said member;
• at least two cylindrical conductors sized and configured to be received into said grooves;
• a bracket having a pair of conductive clamp legs with concave portions that conform to the exposed portions of the conductors;
• and
• at least one lamp mounting fixture having an insulating body and conductive members comprising elongated rectangular bars sized and configured to be mounted in electrical communication with said clamp legs and so as to rotate with respect to said bracket.

A support rail for use in a track lighting system, comprising:

• an elongated extruded insulator having a base portion and a pair of partial cylindrical grooves, said insulator being plastically flexible so as to be able to bend and be arranged non-linearly;
• a pair of cylindrical conductors held within said grooves and separated by said base portion said conductors being at least partially exposed and accessible from an exterior location;
• and
• an elongated mounting rib joined to said insulator base at a neck and to be forced between a pair of resilient opposed legs of a mounting frame to mount a length of said support rail.

A track lighting system, comprising:

• a flexible support rail having a pair of parallel spaced cylindrical conductors separated by an insulating extruded member, said conductors being at least partially exposed and accessible from an exterior location;
• a bracket adapted to clamp to said conductors, said bracket having a pair of conductive clamp legs with concave portions that conform to and clamp against said exposed portion of said conductors in either straight and bent regions of said support rail;
• and
• a lamp mounting fixture having conductive members adapted to be mounted in communication with said clamp legs and to rotate with respect to said bracket,
• wherein said concave portions of said bracket is sized and configured to clamp to said support rail and rotation of said bracket about said support rail is constrained by at least one fastener, and wherein electricity from said conductors may conduct directly through said bracket clamp legs to said fixture conductive members to provide power to an associated lamp.

A method of configuring a track lighting system by mounting at least one lamp fixture in a fixed position with respect to a rail, comprising the steps of:

• mounting a support rail to a location fixed with respect to a reference frame, said support rail having a pair of parallel elongated conductors having exposed arcuate portions with offset axes, said conductors separated and supported by a flexible elongated insulating member;
• clamping a bracket to said conductors, said bracket having gripping portions that conform to the exposed portions of the conductors by contacting one of said gripping portions to one of said conductors and rotating said bracket with respect to said rail to cam said other gripping portion over the other conductor, wherein the gripping portions of the bracket clamp to the support rail to secure said bracket and constrain rotation of the bracket about the support rail;
• and
• electrically connecting a lamp fixture to said bracket, wherein electricity from said conductors may conduct directly through said bracket clamp legs to said fixture to provide power to an associated lamp.
