    摘要： The illumination system (1) has a substrate (2) and an active layer (3) comprising an electroluminescent material, in which the active layer (3) is present between a first, optically transparent electrode layer (5) and a second electrode layer (7). The illumination system (1) is characterized in that a light-scattering layer (28) comprising a medium having light-scattering properties is present in a forward direction (29) with respect to the active layer (3), in which the non-scattered fraction of a (collimated) light beam, when passed through the light-scattering layer (8) in the forward direction (29), is in the range between 0.05 and 0.8, preferably in the range between 0.1 and 0.5. The light-scattering properties of the medium are preferably stronger as the light is more obliquely incident, as is achieved by using birefringent particles and/or media. A very suitable light-scattering layer (28) is a (half) monolayer of TiO.sub.2 particles provided on the substrate (2), with an average size of the (spherical) particles of 0.1-1 .mu.m. The light output of the illumination system (1) is further improved by providing the edges of the substrate (2) with a reflective coating (26).

    摘要： An organic electroluminescent device includes an electroluminescent element, which is enclosed in a housing. The deterioration in uniformity of the luminous surface, which occurs when an electroluminescent device is stored or operated under ambient conditions, and which deterioration manifests itself, for example, in the form of "dark spots", can be overcome to a substantial degree in accordance with the invention by using an airtight and waterproof housing which is sealed by a low-melting metal, such as a BiSn alloy.
