Abstract (en)
[origin: EP0063393A1] Method of producing a low-pressure mercury vapour discharge lamp having a discharge vessel (1), a metal or an alloy which forms an amalgam with mercury being provided in the discharge vessel (1) before the desired gas atmosphere is established in the discharge vessel (1) and the discharge vessel (1) is sealed in a vacuum-tight manner, at least the metal or the alloy (11) being in a closed container (8) which is provided near a portion (9) of the interior wall of the discharge vessel (1), the container (8) being opened after the discharge vessel (1) has been sealed in a vacuum-tight manner, at least a portion of the metal or the alloy (11) then leaving the container (8) and moving to the interior wall portion (9) located near the container (8).
