ABSTRACT:
BACKGROUND OF THE INVENTION
Track lighting is accepted both in commercial and residential applications. The advantages of track lighting are well recognized, in that, lights may be placed and the position of the lights may be changed to accommodate changes in display of merchandise in commercial applications and rearrangement of furniture in residential applications. Heretofore, track lighting has been generally arranged in straight lines. In certain applications, it is desirable to be able to provide a bend or a curve in the track to accommodate a particular structure, such as, a corner so that it is desirable to bend a track around a corner, or to bend or curve track to reflect or mimic the arcuate nature of an architectural environment, such as, columns, arcuate walls and the like, or a lighting arrangement having several curves in the track may be found desirable.
Track lighting often uses low voltage lamps, such as, 12-volt or 24-volt lamps. Customarily, the track carries a 110-volt current. When it is desirable to have a low voltage lamp, a lamp with a step down transformer is mounted on the track. The utilization of the step down transformer for each lamp makes the track lighting installation expensive. The track with many transformers is heavy in the event that there is a number of low voltage lamps on a given track.
It is desirable to provide a track which may be formed to accommodate a particular configuration and to carry a low voltage, so that low voltage lamps may be mounted on the track without a separate step down transformer in association with each lamp.
BRIEF SUMMARY OF THE INVENTION
The present invention is a low voltage track lighting system. The system includes a bendable essentially flat track which may be formed to a desired configuration. The flat track includes a flat insulator base having a pair of opposed flat sides so that the base has a depth greater than its thickness. A thin flat electrical conductor is fixed to each of the flat sides so that there are electrical conductors on opposite sides of the track. A step down transformer adapted to be connected to a conventional source of electric power is connected to the track. A mount is connected to the track to support the track. The mount is adapted to be fixed to a supporting surface to be held thereby. An electric conductive path inside the mount is connected to each thin flat electrical conductor and to the step down transformer. An adapter is supported on the track and is in electric contact with each of the conductors of the track. A low voltage lamp is supported on the adapter and is in electric contact with the adapter to be energized by a current from the step down transformer.
