Abstract

The electronic ballast may be fitted to a wide variety of third party lamps and is usually controlled to allow for a variety of light settings. A simple ballast circuit is provided in which both the ignition and regulation functions are carried out by the same inductor. This removes a switching stage resulting in better efficiency. The ignition energy of the lamp is progressively built up which helps reduce Radio Frequency Interference and reduces Electrical Magnetic Interference and reduces wear on the lamp components.
