Title:
閃光放電管及びその製造方法及び該閃光放電管を備えたストロボ装置
Document Type and Number:
Japanese Patent JP6799745
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: a flashing discharge tube which can materialize the significant improvement in a high heat resistance property and a high thermal shock resistance property, and which can be formed inexpensively; a method for manufacturing the flashing discharge tube; and a strobe device with the flashing discharge tube.SOLUTION: A flashing discharge tube 1 is configured so that a pair of discharge electrodes consisting of an anode A and a cathode C are air-tightly sealed at both ends of a light transmissive envelope 2 with a xenon gas 3 filled in the envelope. The envelope 2 is formed by aluminosilicate glass. Of the discharge electrodes, at least the cathode C is air-tightly sealed in the aluminosilicate glass tube so as to have an outer diameter smaller than an inner diameter of the aluminosilicate glass tube, by locally heat-melting only a second end vicinity including a cathode bead 5 formed on an electrode pin and a second end of the aluminosilicate glass tube and thus causing the second end to sink into a substantially central portion of a side face of the cathode bead 5 to form a concave portion in the substantially central portion of the side face of the cathode bead 5.SELECTED DRAWING: Figure 1
