Abstract
An illumination device for a motor vehicle includes one or more LED units having one or more LEDs, and a plate-shaped diffuser having a first and second delimiting surface, between which a light-diffusing material having a specified thickness is located. A face of the diffuser, which is provided between the first and second delimiting surfaces, forms the light emission surface of the illumination device that is visible to an observer. The LED unit or LED units are arranged adjacent to the first delimiting surface and, during operation, emit light toward the first delimiting surface, which enters the diffuser via the first delimiting surface. The diffuser is designed and arranged such that at least one part of the light of the LED unit or LED units entering via the first delimiting surface is directed in the diffuser to the light outlet surface and emerges there from the illumination device.
