Abstract

A light-emitting module includes a supporting element, a number of optoelectronic semiconductor components mounted on the supporting element for the generation of electromagnetic radiation, and a metallic connecting layer by means of which the optoelectronic semiconductor components are supplied with operating voltage. An insulation layer is arranged in a region of the optoelectronic semiconductor components between the supporting element and the metallic connecting layer. The metallic connecting layer forms a light shade for the optoelectronic semiconductor components, so that the electromagnetic radiation is only emitted in a specified direction.
