Abstract
Abstract A low voltage track lighting system is provided wherein the track transmits current at 12 V AC to standard quartz halogen 12 volt lamps. The track may be made of interlocking components, namely; an electrical strip made of copper tubes partially embedded in a flexible plastic member, and a metal bracket for attachment to a ceiling, wall, or other support. The attachment system between the track and a given fixture uses magnetic attraction, and wherein replaceable magnets in the mount of each fixture attach to the metal bracket of the track to hold the fixture in place and provide the force for contact with the electrical strip.
