A cap for securing a plurality of discharge tubes to a discharge lamp assembly includes a pair of ribs formed on a base plate of the cap. The ribs guide adhesive towards openings in the base plate through which the tubes extend. Adhesive is kept away from the base plate perimeter, which may include a rim, such that assembly of the cap with a housing does not upset the adhesive bond securing the discharge tubes to the cap. Similarly, an assembly method for the cap involves the step of forming a pair of ribs on the base plate of the cap.

A junction component fixed on a PCB (13) has a slot (4) suitable for accepting the electrical leads (10) protruding from the electrical unit and also has a base part (11) and a connection part (12). The base part (11) is embedded into the PCB (13) and is connected with its corresponding output. The leads of the electrical unit are connected to a connection part (12). At the place of connection, the orientation of the electrical leads is substantially perpendicular to the plane of the PCB (13). The direction in which the electrical leads are connected to the connection part (12) is substantially parallel to the plane of the PCB (13). The base part (11) comprises a base plate (1) and tabs(s) (8a-8c) bending out from it. The tab(s) protrude(s) into openings (17) formed in the PCB (13) and is (are) embedded there in a way also ensuring electrical contact to the PCB (13). The base plate (1) connects the tab(s) (8a-8c) with the connection part (12), and the connection part (12) is made to have an orientation substantially in or parallel to the plane of the base plate (1).

摘要:
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.
