<p>In the manufacture of a two-sided flattened metal halogenide high-pressure discharge lamp (19), the following process steps are carried out: preforming of the discharge vessel (6) by rolling with N2 dynamic pressure rinse, clamping into the flattening device, introducing the first electro-optical system (7, 8, 9, 10), the power supply (9) being bent in a zig-zag shape and resting on the inner wall of the quartz tube (1) in a self-supporting fashion, manufacture of the first flattened portion (12) with Ar rinse, high-vacuum baking during insertion into the glovebox filled with xenon, filling in the filling substances (14, 15), introducing the second electro-optical system (7, 8, 9, 10), fusing the open tube end tight with a plasma torch, removal from the glovebox, manufacture of the second flattened portion (18) with simultaneous freezing out of the xenon contained in the discharge vessel (6) at at least -112 DEG C, removal of the lamp (19) from the flattening device and removal of the projecting ends of the quartz tube. There is no pump tube on the discharge vessel (6). <IMAGE></p> |
