Abstract

Einseitig gesockelte Hochdruckentladungslampe (31), bestehend aus einem zylindrischen Außenkolben (32) und einem in etwa axial darin angeordneten zweiseitig gequetschten Entladungsgefäß (33). Die sockelferne Zuleitung (37b) des Entladungsgefäßes (33) ist mit der sockelfernen Stromzuführung (48) verbunden, die außen am Außenkolben (32) zum Sockel (42) zurückgeführt ist. Die sockelferne Stromzuführung (48) ist aus einem Ein­ schmelzteil (49) und einem Rückführungsteil (50) zusammengesetzt, wobei jedes dieser Teile (49, 50) eine eigene Ausdehnungsschleife (51, 53) besitzt. Das Einschmelzteil ist direkt in die axial im kuppen­ förmigen zweiten Ende (39) angeordnete Pumpspitze (40) eingeschmolzen. Figur 3. High-pressure discharge lamp (31) with a base on one side, consisting of a cylindrical outer bulb (32) and a bilaterally arranged approximately axially therein squeezed discharge vessel (33). The most distant Lead (37b) of the discharge vessel (33) is with the socket-remote power supply (48) connected to the outside on the outer bulb (32) is returned to the base (42). The power supply (48) which is remote from the base is of one type melting part (49) and a return part (50) composed, each of these parts (49, 50) has its own expansion loop (51, 53). The Melting part is directly in the axially in the crest shaped second end (39) arranged pump tip (40) melted down. Figure 3.
