摘要： A negative glow discharge lamp having improved efficacy enabled by reducing the anode work function by the introduction of a metal-based gas into the lamp envelope for absorption on the anode. The metal-based gas is preferably cesium but may also, for example, be sodium.

摘要： A negative glow discharge lamp including a light transmitting envelope having supported therein electrode means for establishing a negative glow discharge in the lamp. The fill material includes a metal-based gas such as sodium which, upon excitation thereof, directly emits visible light. The sodium has a resonance radiation in the visible part of the spectrum. The cathode is a hot cathode.

摘要： A high pressure sodium arc tube assembly includes a light-transmitting arc tube containing a fill material including sodium and mercury, a pair of electrodes sealed in opposite ends of the arc tube, and a filament or other resisitive member located within the arc tube and extending between opposite ends thereof. The filament is electrically connected to the electrodes. The filament provides a sufficient electric field and an abundance of electrons dispersed throughout the discharge region to initiate an arc discharge when the electrodes are energized. The filament is selected to produce an electric field in the discharge region prior to initiation of arc discharge of at least 20 volts per centimeter. After an arc discharge is initiated, the voltage between the electrodes drops, and the filament is partially short-circuited by the arc discharge. The filament provides fast initial starting and fast hot restarting, while eliminating the requirement for high voltage starting pulses.
