Abstract

PURPOSE:To shorten luminous buildup time, namely, luminous reset time at the time of relighting attendant upon putting out by forming a sealing member into a plate form, installing a fine tube in this plate-form sealing member, and setting up main amalgam in this fine tube as approached to an opening at the discharge space side. CONSTITUTION:Main amalgam consisting of Bi-In-Hg alloys is housed in a fine tube 6, and it is held by a contracted part 9 without moving to the side of a discharge space 8. A button stem 20 decreases in height projecting to the discharge space side as compared with the conventional flare stem. Consequently, length L2 of a passage connecting the main amalgam 10 to an opening end to be released to the discharge space 8 of an interconnecting hole 21 is made shorter than ever before. Accordingly, passage resistance at a time when excessive mercury in the discharge space 8 returns to the main amalgam 10 becomes lessened, so that a return of this mercury is quickly performed. In consequence, luminous buildup time, namely, luminous reset time attendant upon unlighting time is shortened.
