Lamp assembly with a retainer connecting a stem to a lamp capsule

摘要

A stem (290) and lamp capsule (230) are connected together as an assembly (200) using a retainer (260) such that the stem is clamped to one end of the retainer and the capsule is clamped to the other end of the retainer. An oxidizable fuse (250) is connected between leads (235,240) of the capsule and electrical conductors (215,220) of the stem. The retainer maintains the rigidity of the assembly and keeps a constant distance between the stem and the lamp capsule so that the repeatability and failure parameters of the fuse length can be maintained within acceptable tolerance.
