FIELD: physics. ^ SUBSTANCE: illumination device with a light-emitting layered structure (4) formed on a substrate (2), has at least one electroluminescent layer (42) between a first electrode (41) and a second electrode (43) for radiating scattered light, having Lambert distribution, through the substrate (2). The substrate has at least one first region (21) of the substrate for transmitting and radiating scattered light (31) and at least a second region (22) of the substrate for collimating scattered light and radiating directed light (32), which significantly differs from Lambert distribution. ^ EFFECT: ensuring simultaneous radiation of scattered and directed light by an illumination device with a single light source. ^ 11 cl, 7 dwg |
