Abstract (en)

The lamp (1) has an elongated discharge vessel (2) accommodated in a tubular outer bulb (3), which is held at one end in a base. The outer bulb is surrounded by a second outer bulb (15) i.e. envelope, which is fastened in a region of the base. The process of fastening is performed with the aid of a pin-like fastening unit e.g. screw, that is guided through a hole and anchored in a cutout. The second outer bulb is positioned in form-fitting fashion on the first outer bulb in a region of a pinch (8). The second outer bulb is mounted on a stop unit that projects laterally at the base.
