Low beam headlight that can be obtained with small installation length and high light/energy output are described. A light source arrangement is provided, which generates a light cone of light that is less divergent in a first transverse direction than in a second transverse direction perpendicular to the first transverse direction, and this light source arrangement is used to illuminate three lens arrays arranged next to one another along the second transverse direction, which are thus each irradiated on the input side by an associated one among segments of the light cone arranged next to one another in the second transverse direction and output low beam on the output side with a luminous intensity angle distribution modified with respect to the light cone.

The invention relates to an arrangement for a spatially resolved and wavelength-resolved detection of light radiation emitted from at least one OLED or LED. A multilayer system is arranged between an electrode, an OLED or an LED, and a substrate and is formed using layers formed alternately above one another from a material having higher and lower optical refractive indices n. In this respect, light radiation from the at least one OLED or LED and having a plurality of different wavelengths &#x3bb;, . . . &#x3bb;n thus exits the multilayer system. Light radiation that exits at different wavelengths &#x3bb;, . . . &#x3bb;n at different angles is incident onto at least one detector array after at least a simple refraction at an optical element or after reflection at a layer or at a layer system of a sensor such that light radiation at a wavelength &#x3bb;, . . . or &#x3bb;n is incident onto a respective detector element of the detector array. The detector elements of the detector array are arranged discretely from one another.
