Track lighting system

Abstract

A pendant mounted track lighting system includes an electronic display for use in an operatory environment. In particular, the invention is directed towards a pendant mounted track lighting system that incorporates and integrates intraoral illumination for illuminating a patient's mouth area, general room or ambient lighting in the operatory environment for patients and practitioners, directional task lighting for work surface areas, and electronic display for patient stimulation. The track lighting system includes a housing assembly attached to one or more elongated members for attachment within the operatory environment, one or more ambient lighting assemblies, an intraoral light assembly having a carriage mechanism, an electronic display, and one or more directional task lighting assemblies in a single track lighting system.
