Abstract: An elongated lead frame (100) for a plurality of solid state light emitters (116), an elongated lighting assembly and a method of manufacturing an elongated lead frame are provided. The elongated lead frame comprises a first patterned layer (310) of an electrically conductive material and a second patterned layer (320) of an electrically isolating material. The first patterned layer comprising two electrically conductive tracks (102) that comprise first structures (316, 316?) for a first layer of a stack of light emitter islands and two electrically conductive connections between the first structures, at least one of the electrically conductive tracks comprises in between pairs of neighboring first structures a winded portion for forming a flexible electrically conductive connection in between the pairs of neighboring first structures.
