Abstract

An illumination module with at least one thin-film light emitting diode chip which is applied on a chip carrier having electrical connecting conductors and has a first and a second electrical connection side and also an fabricated semiconductor layer sequence. The semiconductor layer sequence has an n-conducting semiconductor layer, a p-conducting semiconductor layer and an electromagnetic radiation generating region arranged between these two semiconductor layers and is arranged on a carrier. Moreover, it has a reflective layer at a main area facing toward the carrier, which reflective layer reflects at least one part of the electromagnetic radiation generated in the semiconductor layer sequence back into the latter. The semiconductor layer sequence has at least one semiconductor layer with at least one micropatterned, rough area. The coupling-out area of the thin-film light emitting diode chip is essentially defined by a main area remote from the reflective layer and is free of housing material such as potting or encapsulating material.
