Abstract (en)
With the intention of restricting the storage volume of semi-manufactures in the manufacture of compact fluorescent tubes with external ballast and compact fluorescent lamps with integrated ballast, there is provided a base upper-part (5) which can be joined alternatively to the base (9) of a compact fluorescent tube with external ballast or to a housing (11) configured to enclose ballast and provided with an E27-base and intended for compact fluorescent lamps with integrated ballast. In order to provide a durable connection between the base upper-part (5) with cemented-in discharge tubes (1, 1 min ), and a respective base lower-part (9; 11), the latter is provided with a circumferentially extending ridges which, when the parts are pressed together, engages a groove (8) formed on the inner surface of a flange (7) that extends circumferentially around the base upper-part (5). <IMAGE>
