| titleOfInvention | High pressure sodium vapor lamp stabilized for pulse operation |
| abstract | ABSTRACT OF THE DISCLOSURE High pressure sodium vapor lamps operated on sonic frequency pulses with short duty cycle in order to raise the color temperature are subjected to arc instability near the electrodes and to overheating of the end closures, parti-cularly that at the anode end when unidirectional pulsing is used. Stability and long life are achieved and over-heating is prevented by using electrodes of cross-sectional area from 0.3 to 0.4 times the envelope cross section and lengthening the distance from closure to the electrode tip so that the arc gap is less then 80% of the gas column length. |
