  • the lamp base including the adjusting sleeve can be preassembled and only then the fixing ring with pinch seal of the lamp vessel can be introduced. This allows a greater automation of the manufacturing process of the lamp cap and thus a cost reduction in the manufacturing process.
  • the threading slope is formed integrally with the fixing ring, so that a solid component with advantageous mechanical properties is present.
  • the threading bevel is formed over the entire circumference of the fixing ring, so that a uniform threading of the fixing ring into the sleeve and a uniform alignment of the lamp in the lateral direction can take place. It is further preferred that the Kladelschräge is formed as two circumferentially spaced portions, between which a respective recess is provided. A strip connection may be located in this recess during the production process, so that the holding of the fixing ring can be made simple during the production process via this strip connection.
  • the threading slope comprises significantly more than two segments arranged along the fixing ring circumference, which are bent inwards, so that the fixing ring has a reduced outside diameter in the region of the segments. The distance between the individual segments of the threading slope is advantageously as small as possible in order to avoid catching the parts during transport and assembly.
  • the fixing ring is produced from a stamped strip. As a result, a plurality of fixing rings can be formed simultaneously.
