Abstract: A light engine for a tube lamp has a substrate defining a longitudinal direction, having at least three conductive traces extending in the longitudinal direction. At least two of the conductive traces are divided into a plurality of trace sections. The light engine further includes a plurality of semiconductor light emitting elements, each light emitting element having two electric terminals and being arranged perpendicular to the longitudinal direction and electrically connected with a first electric terminal to one of the conductive traces and with a second electric terminal to another one of the conductive traces.

Abstract: A lamp includes a base with at least two electrical connecting elements. A bulb is rotatably mounted relative to the base. A light engine is arranged in the bulb with at least one light-emitting element and an electrically conductive substrate on which the light-emitting element is arranged. An electronic driver is connected to the electrically conductive substrate for activation of the light-emitting element. The base has a base sleeve in which the electronic driver is arranged. The electrically conductive substrate has a flexible connecting section between the electronic driver and the light-emitting element.
