1. An external lighting device for lighting surroundings of a motor vehicle, comprising:
a design screen having a surface shape; and
at least two capturing devices with camera sensors and carrier mediums for the camera sensors, respectively,
the at least two capturing devices arranged spatially separated at opposite edge regions of the design screen,
a carrier medium of the carrier mediums of a capturing device of the at least two capturing devices including a light guide having an external light input region and an external light output region, so that each carrier medium corresponding to each capturing device of the at least two capturing devices is arranged on different sides at the opposite edge regions of the design screen, and each carrier medium is adapted to the surface shape of the design screen, so that each carrier medium is planar with a width and a length of each carrier medium greater than a thickness of each carrier medium,
the external light input region including a first holographic element with a first deflection structure to couple external light to be incident on the first deflection structure from the surroundings into the carrier medium,
the carrier medium being configured to transmit the external light from the external light input region to the external light output region by internal reflection,
the external light output region including a second holographic element with a second deflection structure to couple the external light to be incident on the second deflection structure out of the carrier medium, and
the camera sensors of the at least two capturing devices being configured to capture the external light coupled out of the external light output region of each carrier medium of the carrier mediums respectively corresponding to the camera sensors, so that at least two camera sensors of the camera sensors provide image data correlated with external light captured by the at least two camera sensors corresponding to capturing regions of the at least two capturing devices at the opposite edge regions of the design screen, respectively.
