Abstract
An incandescent lamp having a substantially cylindrical glass bulb closed at one end by an exhaust-sealed portion, the entire length of which is reduced by reducing the inclination of a portion continuing from the cylindrical major portion of the glass bulb to the exhaust-sealed portion, as well as, a process for producing the same. The glass bulb containing filaments is closed at one end by the exhaust-sealed portion, with a shoulder having a substantially truncated conical appearance connecting the exhaust-sealed portion and the substantially cylindrical major portion, wherein the angle formed between the plane orthogonal to the axis of the glass bulb and the surface of the shoulder, i.e. the inclination of the surface of the shoulder, is designed to be 45.degree.or less.
