ABSTRACT:
A method of producing a low-pressure mercury vapor discharge lamp which includes positioning a container in the lamp vessel of the lamp between the electrodes. The container holds a quantity of mercury required for operation of the lamp and is attached to a supporting element (wire). The supporting element is connected to a lead-in wire of a first electrode by a metal connecting wire. A direct current discharge is generated between the container and the second electrode, the mercury escapes from the container, thereafter the connection between the supporting element and the lead-in wire is interrupted.
