本发明涉及一种用于机动车(40)的外部灯光装置(30)以及一种具有这种外部灯光装置(30)的机动车(40)。外部灯光装置(30)包括外观盖板(31)以及至少一个具有图像获取装置(35)和载体介质(12)的检测装置(10)。载体介质(12)被设计为光导体,在其上提供有耦入区域(16)和耦出区域(18)。具有耦入区域(16)和耦出区域(18)的载体介质(12)被设计为面状的并且与外观盖板(31)的表面形状(33)相匹配。耦入区域(16)和耦出区域(18)分别被设计为全息元件(14)。从环境射到外部灯光装置(30)上的光(100)通过耦入区域(16)耦入到载体介质(12)中,借助于内反射传输到耦出区域(18)并且在那里被耦出。图像获取装置(35)被设计为用于,获取耦出的光(100)并且将其提供为与所检测的光(100)相关的图像数据。

    A design screen and at least one detection device with an image capturing device and a carrier medium are provided in an external lighting device for a motor vehicle. The carrier medium is a flat waveguide on which a coupling region and a decoupling region are provided. The carrier medium is adapted to the surface shape of the design screen. The coupling region and the decoupling region are each a holographic element. Light incident on the external lighting device from the surroundings is coupled into the carrier medium via the coupling region, is transported to the decoupling region by internal reflection in the waveguide, and is decoupled at the decoupling region. The image capturing device detects the decoupled light and provides image data which correlates to the detected light.
