摘要： In an electric incandescent lamp having a bulb (1) including a glass pinch (2) which is retained in a metal cap (3) with a rectangular cross-section, the cap is provided with outwardly bent tags (7) at the wider sides (10) of its end facing the bulb (1). The tags (7) each have at their free ends a rim (9) which runs at least substantially parallel to lamp axis (X--X).

摘要： In the ceramic insulating block for halogen lamps, which has a shallow channel with a re-entrant projection at its exit side, the insulating block (1) is provided at the entry side (9) of the shallow channel (2) with a recess (10) having a bell-shaped contour. The apex (11) of the recess extends towards the exit side (4) of the shallow channel (2). The recess has an apex height H.sub.s of .ltoreq.40%, an apex radius R.sub.s of .ltoreq.20% of the height H of the insulating block (1) and a base radius R.sub.B of between 140% and 60% of R.sub.S.

摘要： The electric lamp has a pinched seal (2) which is fixed in a lamp cap (5) with a metal shell (9) with cylindrically bent portions (10) by means of a retaining member (11). The retaining member (11) has a set of brackets (12, 13) between which the pinched seal (2) is clamped in. The clamping force (P) is generated in that the brackets (12, 13), after being inserted in the lamp cap (5), are moved away from one another through openings (14) in the lamp cap before being fixed to the shell (9) of the lamp cap (5).
