Illumination device for a motor vehicle

An illumination device of a motor vehicle, comprising:

• one or more LED units, wherein a respective LED unit comprises one or more LEDs;
• a plate-shaped diffuser, wherein the plate-shaped diffuser has first and second delimiting faces and an end face, between which faces there is a light-scattering material with a predetermined thickness, wherein
• the light-scattering material is disposed along an entire planar extent of the plate-shaped diffuser,
• the end face of the diffuser, which is provided between the first delimiting face and the second delimiting face, forms the only light emergence face of the illumination device that is visible to a user,
• the LED unit or LED units abut against the first delimiting face and, during operation, emit the light in a direction of the first delimiting face, said light entering into the diffuser via the first delimiting face,
• the diffuser is configured and arranged such that the light of the LED unit or LED units entering via the first delimiting face emerges from the illumination device at the light emergence face,
• an optical reflector is arranged at the second delimiting face of the diffuser, at least in a region which lies opposite the LED unit or LED units, wherein the optical reflector reduces light losses in the diffuser,
• the diffuser has a further end face which is arranged at an end of the diffuser that is distant from the light emergence face,
• the LED unit or LED units are arranged adjacent to the further end face, and
• a rod-shaped light guide is disposed in a receptacle, wherein the receptacle adjoins the diffuser at the further end face of the diffuser.
