Abstract
The invention relates to a tube () for a semiconductor tubular lamp (), which tube has at least one holding projection for holding at least one printed circuit board () on the inside of the tube, wherein the tube () is a glass tube, and the at least one holding projection is an inwardly bulging, reshaped burling region (-) of the tube (). A semiconductor tubular lamp () has a tube () and at least one printed circuit board () fitted with a semiconductor light source (), which is accommodated in the tube () and is held transversely to a longitudinal direction (L) of the tube () by means of at least one burling region (-) in a form-fitted manner. A method serves to produce a tube (), wherein the tube () is provided, locally heated, and pressed inwardly at the at least one locally heated point for generating the at least one burling area (-). The invention is in particular applicable to LED retrofit lamps for fluorescent lamps, in particular for replacing conventional tube lamps or flashlights of type T5 or T8.
