Abstract
A ballasting circuit is configured with a circuit having a capability of providing an isolated power supply to various external ballast accessories that interface with a circuit or device for determining the amount of illumination. The ballasting circuit also has a capability of providing isolated power for circuitry within itself such that they can be connected to communication wires external to a lighting fixture without the need of an additional power supply. The ballasting circuit includes one or more gas discharge lighting devices, a source of input power, an electronic ballasting circuit having a regulated direct current requirement and coupled between the one or more gas discharge lighting devices and the source of input power, a heater transformer, a low voltage direct current power supply, a switching device, a regulator circuit, a full wave rectifier, and windings.
