Abstract

A light-emitting window element includes a transparent first carrier layer, a transparent second carrier layer, a substrate with a plurality of light-emitting semiconductor chips arranged thereon, and an optical layer having an adjustable transparency. The substrate with the plurality of light-emitting semiconductor chips and the optical layer are arranged between the first and second carrier layers, and the first and second carrier layers, the substrate with the plurality of light-emitting semiconductor chips and the optical layer form a laminate composite.
