Abstract

A tube for a semiconductor tubular lamp is disclosed, 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 of the tube by means of at least one burling region in a form-fitted manner. 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.
