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.

Luminous means having LEDs

The present invention relates to a lighting means comprising at least two LEDs mounted on opposite sides of a flat printed circuit board, said printed circuit board being combined with a reflector which is free of LEDs, a part of the light emitted by each LED being reflected by the reflector to homogenize the light distribution generated by the lighting means, and specifically in each case with a directional component parallel to a surface direction of the flat printed circuit board.

Lighting means comprising LEDs

A method for producing a barrier layer and a carrier body including such a barrier layer are disclosed. In an embodiment the method includes providing a carrier body including a polymer film having at least one polymer, drying the barrier interface, exposing the barrier interface to one reagent gas, or to a plurality of reagent gases which do not chemically react with each other, so that the at least one reagent gas chemically reacts with the at least one polymer at least inside the polymer film in at least one chemical reaction thereby forming the barrier layer, and removing at least one product gas of the at least one chemical reaction.
