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.

Tubular lighting device assembly

The present invention relates to an end cap () for a tubular light source the tubular light source configured to be arranged in a lighting fixture comprising a socket, wherein the end cap () comprises a housing portion having a connection end, two connector pins () at least partly arranged on an outside of the housing portion at the connection end, wherein the connector pins () are configured to fit in the sockets of the lighting fixture, a first spring loaded switching element () configured to be alternately positioned in an actuated state and a non-actuated state, wherein the first spring loaded switching element () protrudes at the connection end of the housing portion in the vicinity of the connector pins () when positioned in its non-actuated state, and a second spring loaded switching element () configured to be positioned in an actuated state and a non-actuated state, wherein the switching elements () are configured to be individually positioned in their respective actuated states to form an electrical connection between the socket and the tubular light source when the end cap () is mounted into the socket of the fixture.
