Abstract

The present disclosure relates to a luminous means having a cap and an outer bulb in which LEDs are arranged on a flat multilayer substrate which is constructed, at least in regions, from at least two substrate layers between two outside surfaces which are opposite one another, wherein the at least two substrate layers are formed from a flat substrate sheet which is laid back on itself, and wherein the LEDs are mounted on a side surface of the substrate sheet, which at least proportionally forms the two outside surfaces of the multilayer substrate in each case on account of the substrate sheet being laid back, in such a manner that at least one of the LEDs is mounted in each case on both of the two outside surfaces of the multilayer substrate.
