Abstract
A tubular semiconductor lamp having an elongate heat sink formed from sheet metal, at least one strip-shaped circuit board, which is equipped with at least one semiconductor light source and which lies on the heat sink, and a light-transmissive bulb made of plastic, which arches over the equipped circuit board, wherein the circuit board is held in a longitudinally movable manner by the heat sink. A method for producing a tubular semiconductor lamp, which can be applied, for example, to replacement lamps for straight-line fluorescent lamps or linear lamps, of type T5 or T8.
