A tubular solid state lighting device is disclosed having a light transmissive tube. A flexible carrier strip having a first portion attached to an inner wall section of the tube, and comprises an elongate major surface and a further elongate major surface opposite the elongate major surface. The elongate major surface carries a plurality of solid state lighting elements on the first portion and a plurality of electrically conductive contacts on adjacent terminal regions separated by a recess at one end. The flexible carrier strip is soldered to a rigid printed circuit board comprising a first major surface onto which a driver circuit for the solid state lighting elements is mounted facing the flexible carrier strip and a second major surface opposite the first major surface carrying a plurality of spatially separated soldering pads along an edge of the second major surface. The further elongate major surface contacts the second major surface such that each electrically conductive contact is aligned with one of the spatially separated soldering pads and is soldered to said soldering pad by a solder portion extending over the terminal region carrying said electrically conductive contact. A method of forming such an assembly and an assembly method for a tubular lighting device are also disclosed.
