Spark gap device particularly suited for a rapid restrike circuit for
metal halide lamps
摘要:
A spark gap device is disclosed that is particularly suited for a rapid restrike or starting circuit which is employed in sport stadium lighting applications to start or restrike metal halide lamps that have been subjected to a momentary loss of power. The spark gap device comprises two electrodes that are arranged in a parallel side-by-side relationship and spaced apart from each other by a predetermined amount. The spark gap device operates that when a high voltage potential is applied across the electrodes, the generated and reoccuring spark is distributed along the parallel arranged electrodes. The parallel arrangement of electrodes provides for improved life and cooler electrode temperatures as compared to prior art spark gap devices in which the generated and reoccuring spark jumps between the end regions of separated electrodes.
