摘要

High frequency and high voltage device for igniting high pressure sodium lamps, characterized in that it is interposed in the electrical circuit of said lamp and is fed with alternating current that is rectified by a half wave rectifier provided with straightening filter, producing said device voltage pulses that are superimposed on the voltage of the network, from the moment when the voltage in the device reaches a value of one hundred and eighty volts; once the sodium lamp is turned on, when a certain intensity is circulated through the circuit, the device is isolated thanks to a calibrated reactance that costs in series with the lamp and the device, causing a voltage drop sufficient to prevent the terminals from device will reach the operating threshold voltage.
