Abstract

A new and improved gas-filled lamp and method of manufacturing such a lamp, wherein the usual tip-off region on the glass envelope of the lamp is eliminated. In manufac­ ture of the lamp, the lamp envelope (10, 11, 12) is provided with a coaxial mercury trap (25) at the end of the envelope opposite the gas pumping end (26), the electrodes (15, 16) are inserted, air is pumped out, fill gas is pumped in, the envelope is shrunk down onto the electrode (16) at the pumping end, mercury (21) is tipped into the envelope bulb, and the mercury is held against the remote, colder region of the envelope while shrinking down on the second electrode (15).
