Abstract
A bulb-shaped outer envelope for accommodating at least one lamp including a light-emitting body and a control gear is disclosed. The envelope has a substantially spherical section for receiving the light-emitting body, and an elongated end section for receiving at least a part of the control gear components. The elongated end section is provided with a neck section. A substantially tubular neck-extension portion connects to an inner surface portion of and protruding from the neck section. The neck-extension portion is suitable for accommodating a remaining part of the control gear components. In a method for the manufacture of a glass outer envelope, a flare that is normally used in the manufacture of incandescent lamps is turned around by 180°, put into a skirted bulbous envelope, melted into the envelope while the skirt is detached and the flare is formed into a neck-extension portion. A self-ballasted compact fluorescent lamp with the bulb-shaped outer envelope is also disclosed. A part of the ballast components are disposed in the neck-extension portion of the outer envelope.
