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.
An organic radiation-emitting component comprising an active organic layer constituted to generate radiation and one or two radiation-output sides, wherein, 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 1 to 7.5% by weight, with reference to the total weight of the first layer (A), of (6-[4,6-bis(4-phenylphenyl)-1H-1,3,5-triazin-2-ylidene]-3-(2-ethylhexoxy)cyclohexa-2,4-dien-1-one)-, and wherein the second layer (B) contains polycarbonate, and wherein the first layer (A) comprises polymethacrylate and has a thickness of from ≥10 μm to ≤200 μm, wherein the UV protective film is arranged relative to the active organic layer (2) in such a manner that its first layer (A) faces away from the active organic layer (2) and its second layer (B) faces towards the active organic layer (2) and wherein a gloss level for an angle of 60° from a surface, determined according to EN ISO 2813, of the first layer facing away from the active organic layer (2) is greater than or equal to 70.
