Device for detecting fouling on object surfaces in Xenon headlamps for motor vehicles has optical element directly integrated into object surface without cover, at least one coupling point for coupling light in and/or out of optical element

摘要

The device has an optical element (2) that conducts light waves and that is directly integrated into the surface of the object without a cover and with at least one coupling point for coupling light in and/or out of the optical element. The device has an aperture in the surface in which the optical element is arranged. An independent claim is also included for a device for detecting fouling on object surfaces.
