Abstract

A lighting fixture is slidably mounted on a track support which may advantageously be secured to any existing or available structure within or around the work space. In one preferred embodiment, it is secured to the side of a computer monitor which is either located on or adjacent to the work surface which is to be illuminated. The track support may be mounted on the computer monitor or other surface at any angle from vertical through horizontal thus providing a wide variety of options for an individual using the improved fixture of the present invention. The lamp fixture socket support is preferably rotatably mounted on a sliding car member which moves along the track support and also provides a first axis of rotation for the fixture. A reflector housing is also rotatably secured to the sliding car or fixture which thus provides a second axis of rotation for the fixture allowing greatest flexibility for positioning the lamp.

Claims

1. A work space illuminating fixture comprising:

an elongated supporting track attached to a substantially vertical surface;

a fixture support car in sliding engagement with the supporting track;

a fixture socket support rotatably mounted to the fixture support car; and

a reflector housing rotatably mounted to the fixture socket support,

wherein the supporting track has a plurality of dimples for temporarily securing the fixture support car.

2. The work space illuminating fixture of claim 1, wherein the reflector housing is comprised of an elongated rectangular parabolic reflector.

3. The work space illuminating fixture of claim 1, wherein the fixture socket support further comprises an electric switch secured within a cavity in the fixture socket support.

4. The work space illuminating fixture of claim 1, wherein the reflector housing has a light reflector/heat dissipator secured within an inner cavity of the reflector housing.

5. The work space illuminating fixture of claim 1, wherein a detent spring is secured between the fixture support car and the supporting track.

6. A work space illuminating fixture comprising:

an elongated supporting track attached to a substantially vertical surface;

a fixture support car in sliding engagement with the supporting track;

a fixture socket support rotatably mounted to the fixture support car; and

a reflector housing rotatably mounted to the fixture socket support,

wherein upper and lower support rings extend from the fixture support car substantially perpendicular to the supporting track to rotatably secure the fixture socket support to the fixture support car.

7. A work space illuminating fixture comprising:

an elongated supporting track fixed to a side of a monitor;

a fixture support car in sliding engagement with the supporting track;

a fixture socket support rotatably mounted to the fixture support car; and

a reflector housing rotatably mounted to the fixture socket support.

8. The work space illuminating fixture of claim 7, wherein the supporting track has a plurality of dimples for temporarily securing the fixture support car.

9. The work space illuminating fixture of claim 7, wherein the reflector housing is comprised of an elongated rectangular parabolic reflector.

10. The work space illuminating fixture of claim 7, wherein the fixture socket support further comprises an electric switch secured within a cavity in the fixture socket support.

11. The work space illuminating fixture of claim 7, wherein the reflector housing has a light reflector/heat dissipator secured within an inner cavity of the reflector housing.

12. The work space illuminating fixture of claim 7, wherein upper and lower support rings extend from the fixture support car substantially perpendicular to the supporting track to rotatably secure the fixture socket support to the fixture support car.

13. The work space illuminating fixture of claim 7, wherein a detent spring is secured between the fixture support car and the supporting track.

14. A work space illuminating fixture comprising:

an elongated supporting track fixed to a side of a monitor;

a fixture support car in sliding engagement with the supporting track; and

a means for rotating a reflector housing about first and second axis of rotation attached to the fixture support car.

15. The work space illuminating fixture of claim 14, wherein the supporting track has a plurality of dimples for temporarily securing the fixture support car.

16. The work space illuminating fixture of claim 14, wherein the reflector housing is comprised of an elongated rectangular parabolic reflector.
