Abstract

829,022. Discharge lamps. GERMESHAUSEN, K. J. Nov. 6, 1956 [July 17, 1956], No. 33916/56. Class 39(1). [Also in Group XXXV] A cold-cathode gaseous-discharge tube, for use in stroboscopic or flash-photography systems, comprises a plurality of like control or trigger electrodes having operative portions spaced at substantially equal intervals along a straight line between an anode and a cathode, both of which are of the cold-cathode type and are formed of sintered material. In operation anode to cathode discharges are initiated and confined to this line by raising the control electrodes to a potential greater than the potential applied between anode and cathode which latter potential is of itself made insufficient to produce a discharge between anode and cathode. As shown, the trigger electrodes 21, 23, 25, 27 and 29 extend inclinedly into the space between the anode 5 or cathode 7 so that the discharge impedance between successive electrodes is a minimum along the line L, or adjacent electrodes may enter the space from opposite sides, or alternatively the trigger electrodes may be supported by an insulating member extending between the anode and cathode, Fig. 3 (not shown). their lower ends being provided with insulating coverings. Either or both of the electrodes 21, 29 may be provided with insulating coverings 21<SP>1</SP> 29<SP>1</SP> to reduce the initial arc break-down to the adjacent anode or cathode. Particle trapping screens 5<SP>1</SP>, 7<SP>1</SP> may be provided adjacent the anode and cathode as described in Specification 818,505, the anode and cathode preferably being sintered coldcathode type electrodes. The gas filling may be xenon at a pressure of ¢ to 3 atmospheres, adjacent electrodes being spaced # in. apart along the line L. The tube may be disposed in a socket mounted in the focal region of forward or rearward parabolic reflectors to provide directive beams of flashing light, Fig. 5 (not shown). The lead-in connections to the trigger electrodes are each provided with sufficient isolating impedance, such as a capacitor or coaxial-line section, so that successive break-downs occur in series between consecutive electrodes. The outer ends of the lead-in connections are connected together and to a trigger circuit (see Group XXXV).
