Abstract

In various exemplary embodiments, a method is provided for producing an assembly emitting electromagnetic radiation. In this case, a component composite structure is provided which has components emitting electromagnetic radiation, which components are coupled to one another physically in the component composite structure. In each case at least one component-individual property is imparted to the components. Depending on the determined properties of the components, a structure mask for covering the components in the component composite structure is formed, wherein the structure mask has structure mask cutouts corresponding to the components, which structure mask cutouts are formed in component-individual fashion depending on the properties of the corresponding components. The structure mask cutouts provide phosphor regions, which are exposed in the structure mask cutouts, on the components. Phosphor layers are formed on the phosphor regions of the components.
