<p>An illumination assembly allowing quick and easy access to traffic, billboard or other lighting is provided. The illumination assembly includes a rotatable conveyor assembly (20) having a cable or cord (50) driven by one or more drive pulleys (80) to rotatably place lighting luminaires (90) over supported operating, maintenance or other areas. When a light bulb contained in a luminaire burns out or otherwise requires servicing, the rotatable conveyor assembly (20) is activated to drive the corresponding luminaire to a maintenance area, having a maintenace support plate (170). The luminaire is conveniently and safely serviced, and the conveyor cord (50) then drives the luminaires (90) back to their normal lighting positions. Reconfiguration in the field with greater or lesser luminaires, track size or otherwise is possible.</p> |
