Abstract
A recessed track lighting system includes a housing recessed in a ceiling and having a top wall, an elongated opening spaced downwardly from the top wall and a channel along the top wall extending parallel to the opening and laterally centered in respect thereto, and at least one light fixture mounted in the housing by means of an adapter releasably engageable in the channel and being movable therealong. The adapter defines an axis of rotation that substantially bisects the width of the elongated opening and a lamp head support in turnable about such axis of rotation and has an arcuate guide extending generally radially from the axis of rotation. The arcuate guide has a curvature centered substantially at the lateral center of the elongated opening, and a lamp head is adjustably mounted on the arcuate guide and includes a light source directing light along a light beam axis which, in all positions of the lamp head along the arcuate guide, intersects the axis of rotation at the plane of the opening.
