Abstract
A ballast includes circuitry to allow the level of the lighting to be adjusted as well as circuitry that interfaces the ballast to a control system via the power line. The ballast is provided for adjusting the output by using a conventional triac phase chop dimming circuit. The basic concepts of the circuit can also be used to drive flat panel (electro luminescent) light source.
