    摘要： A D.C. operable, miniature, low-wattage, single ended, arc discharge lamp. The cathode electrode includes electrical field modifying means to insure that the arc strikes between the electrode tips. During high pressure (.about.10 atm) operation electrode heating of the anode is dominated by electron bombardment, which creates substantially higher heat at the anode tip than at the cathode tip (the cathode being heated by ion bombardment and cooled by thermionic electron emission). Heat conducted down the anode electrode is dissipated in the single press and contributes to the heat conduction in the closely adjacent cathode electrode thereby reducing the net heat loss therein and helping to maintain the desired cathode temperature.

    摘要： A miniature, low-wattage, discharge lamp operable on direct current employs substantially parallel electrodes sealed in a single press seal. The electrodes are configured to provide an arc which is substantially parallel to the longitudinal axis of the lamp with the cathode being substantially longer than the anode. Heat generated at the anode is dissipated through the seal to the cathode allowing the cathode to operate hot enough to be stable. The chemical fill for the lamp employs a mol ratio of thorium to cesium to permit good light output and good color rendition.
