Abstract

A filament includes a multiplicity of light-emitting semiconductor chips, wherein the semiconductor chips are arranged on a carrier, the semiconductor chips being electrically contacted, a scattering structure is configured to scatter light of the light-emitting semiconductor chips, the scattering structure is formed by structuring a surface, a converter covers the light-emitting semiconductor chips, and the structuring of the surface is formed on a surface of the converter.
