Abstract
A lamp ignition circuit provides a high voltage electrical pulse to ignite a gas discharge lamp. A non-linear filter element within a charge circuit regulates the voltage of the ignition pulse such that the ignition pulse remains within a prescribed voltage range over a wide variety of conduit lengths between the lamp and the lamp ignition circuit. This allows for the ballast and lamp ignition circuit to be mounted either close to the lamp or far from the lamp without modifying the ignition circuitry.
