ABSTRACT:
The electric incandescent lamp has a multi-use lamp vessel having a neck-shaped wall portion, a wall portion which is curved in accordance with a first circuit arc and extends substantially in the transverse direction, and a wall portion which is curved in accordance with a second circular arc and extends substantially in the axial direction. A filament is arranged in the proximity of the largest diameter. The electric incandescent lamp has the advantage that, independent of its finish it has a lamp vessel of the same shape and the same mounting means for the filament. The manufacture of incandescent lamps of different types is thereby simplified considerably.
