摘要： An optoelectronic device comprising at least one optoelectronic active region comprising at least a rear electrode and a front electrode between which an organic optoelectronic material is sandwiched, said rear electrode being reflective, and a cover layer arranged in front of said front electrode. The cover layer comprises a material with light-scattering particles of a first material dispersed in a transparent matrix of at an least partly hydrolyzed silica sol.Due to the highly scattering propertied of the cover layer, the device is essentially concealed behind the cover layer when not in its operative state.

摘要： The invention relates to alighting apparatus comprising a light emission unit (2) for emitting light (3) from an emission surface (4) in a main emission direction (6), and an outcoupling unit (7) for coupling the light out of the light emission unit. The outcoupling unit comprises a first surface (8) having a first central region (9) optically coupled to the emission surface and a first peripheral region (10) enclosing the first central region, and a second surface (11) opposite to the first surface. The peripheral regions can be structured, wherein the ratio of a) the area of the emission surface to b) the area of the first surface or the second surface is smaller than 0.5. This configuration can significantly decrease the likelihood of reabsorption of light by the emission surface, thereby increasing the efficiency of extracting light out of the lighting apparatus.
