ABSTRACT:
A lighting assembly having a series of telescoping tubes is mounted in a box, and an interior spring urges the tubes to extend out of the box into a use position. A light on the free end of the tubes simulates a candle. One end of cable within the spring is connected to the free end of the tubes, and the other cable end is wound on a drum connected to a brake/motor combination. When the brake is released, the cable unwinds and the tubes extend in response to the urging of the spring. When the tubes are to be retracted, the motor winds the cable back onto the drum. A group of assemblies are mounted in the box and their cable drums controlled by a common drive shaft. Drums of different diameters are provided to determine the extension of the cables, and hence the tubes, to thereby provide lighting fixtures of different heights.
