Title: John C Pegg: Innovator in Discharge Lamp Technology
Introduction
John C Pegg is a notable inventor based in London, GB. He has made significant contributions to the field of electrical engineering, particularly in the development of discharge lamp technology. His innovative approach has led to the creation of a unique starter circuit that enhances the functionality of hot cathode discharge lamps.
Latest Patents
John C Pegg holds a patent for a "Discharge lamp with starter circuit." This invention features a starter circuit designed for a hot cathode discharge lamp, which includes a switching element connected across the lamp. This allows a cathode heating current to flow before opening to permit the lamp to strike. The circuit utilizes a thyristor as the switch element, along with a control circuit that renders the thyristor conductive at a specific point during each voltage cycle. The control circuit also incorporates means for increasing the instantaneous applied voltage required to trigger the thyristor with successive cycles after the circuit is switched on. This mechanism includes a capacitor that progressively charges to provide an increasing bias that must be overcome by the applied voltage. If the lamp fails to strike, the triggering voltage continues to rise until it becomes too high for the thyristor to trigger, preventing any damage to the starter circuit or the lamp ballast.
