Abstract

A track lighting fixture in which decorative lamp housings are adjustably positionable along a fixture track, and which provides for several angular adjustments of each decorative lamp housing. Each decorative lamp housing comprises a common outer housing in which different interchangeable decorative inserts can be interchangeably inserted. In first and second embodiments, each track lamp fixture has a power supply housing for an enclosed power transformer and power supply which is attached to the fixture track. A support element of the power supply housing is rotationally mounted relative to the power supply housing and supports a decorative lamp housing thereon, such that the support element and decorative lamp housing can be rotated to different angular positions. In the first embodiment, the power supply housing comprises a cylindrical shaped housing, and in the second embodiment, the power supply housing comprises a rectangular shaped housing. In a third embodiment, each track lamp fixture does not include a power supply housing, and instead is powered directly from the fixture track.

Claims

1. A track lighting fixture comprising:

a. a fixture track along which one or more track lamp fixtures can be adjustably positioned and which provides electrical power to the one or more track lamp fixtures positioned along the fixture track;

b. at least one track lamp fixture adjustably positioned along the fixture track and having a power supply housing which is adiustably positioned along and attached to the fixture track, wherein the power supply housing comprises a cylindrical shaded housing which is supported to extend below the fixture track, and a support element of the power supply housing is rotationally mounted relative to the power supply housing and supports a decorative lamp housing thereon, wherein the rotationally mounted support element comprises a circular cup-shaped support element rotationally mounted to the bottom of the cylindrical housing, such that the support element and decorative lamp housing can be rotated to different angular positions relative to the power supply housing.

2. A track lighting fixture as claimed in claim 1, wherein the support element supports the decorative lamp housing thereon by a swivel attachment which includes a pivot shaft, about which the decorative lamp housing rotates relative to the support element.

3. A track lighting fixture as claimed in claim 2, wherein the swivel attachment pivot shaft is horizontally positioned.

4. A track lighting fixture as claimed in claim 1, wherein the cylindrical housing provides an enclosure for a power transformer and regulated power supply for the at least one track fixture.

5. A track lighting fixture as claimed in claim 1, wherein each decorative lamp housing comprises a common outer housing in which different interchangeable decorative inserts can be interchangeably inserted.

6. A track lighting fixture as claimed in claim 5, wherein the interchangeable decorative inserts can be transparent, translucent or opaque.

7. A track lighting fixture as claimed in claim 5, wherein the interchangeable decorative inserts can be a stepped glass insert, a metal mesh insert, a perforated metal insert, an opaque insert, or no insert.

8. A track lighting fixture as claimed in claim 1, wherein the power supply housing comprises a rectangular shaped housing, and the rotationally mounted support element comprises a circular shaped support element rotationally mounted to the bottom of the rectangular housing.

9. A track lighting fixture as claimed in claim 8, wherein the support element supports the decorative lamp housing thereon by a swivel attachment which includes a pivot shaft, about which the decorative lamp housing rotates relative to the support element.

10. A track lighting fixture as claimed in claim 9, wherein the swivel attachment pivot shaft is horizontally positioned.

11. A track lighting fixture as claimed in claim 8, wherein the cylindrical housing provides an enclosure for a power transformer and regulated power supply for the at least one track fixture.
