Abstract

The present invention relates to an organic radiation-emitting component with an active organic layer constituted to generate radiation and one or two radiation-output sides, characterised in that, on at least one radiation-output side of the component, a UV protective film is arranged and connected to the component, wherein the UV protective film contains at least one first layer (A) and a second layer (B), wherein the first layer (A) contains 0.01 to 20% by weight, with reference to the total weight of the first layer (A), of a UV absorber, and wherein the second layer (B) contains polycarbonate. Furthermore, the invention relates to the use of a component according to the invention as an organic light-emitting diode, and for lighting, especially for general lighting.
