ABSTRACT:
A process for producing a discharge vessel of a flat gas discharge lamp, in which the discharge vessel has a base plate (1), a frame (3) and a cover plate (2), as well as at least one spacer (6) between base plate (1) and cover plate (2). At least between one of the plates (2) and the frame (3), at least one space (6) is initially kept open as a filling opening. By partial fusion of at least a part (4, 5) of the frame, which may also comprise a layer (4) of soldering glass and local elevations (5), the filling opening (6) is eliminated after the filling operation. The distance between the vessel plates (1, 2) is defined by the spacers (7), which remain hard even during the joining operation.
