Abstract

A tracklight system includes an elongated an elongated metallic track generally in the shape of a U, having a base and first and second parallel depending legs with proximal ends extending from the base of the U and having distal ends terminating in a common plane. An elongated insulator is attached to one of the depending legs and having longitudinal slots therein including electrical conductors. Track fixtures each include a fixture adapter attaching a luminaire to the track with an incandescent or gas-discharge luminaire disposed within the track U, substantially between the common plane of the legs and the base of the U. In a preferred embodiment the fixture adapter includes a swivel that permits the luminaire to pivot out of the track aim a light beam in azimuth and elevation.

Dependent claims

A tracklight system (26, 47, 60) comprising:

an elongated metallic track extrusion (28) generally in the shape of a U, having a base (29) and first and second parallel depending legs (30) extending from the base of the U and having distal ends (31) in a common plane;
an elongated insulator (38) attached to at least one of the depending legs has one or more pairs of partially-embedded conductors (39) in longitudinal slots, said conductors (39) connected to an external source of mains power;
at least one light fixture (27, 48, 61) disposed within the track U, substantially between the common plane of the legs and the base 29 of the U, said fixture comprising a luminaire (32, 52, 62) and a fixture adapter (33, 50, 63) attaching the luminaire to the track;
and
an electrical connector (37) supplying electrical power to the light fixture from the track conductors (39).
