Abstract
A light deflection device including a flat, transparent light guide and a microstructure provided at least in regions on the light guide for decoupling light coupled into the light guide. The microstructure has microstructure elements and the microstructure elements in each case have a substantially point-like or line-like geometry for contact with the light guide. Further, a method for manufacturing a light deflection device, an illumination device, and use of a light deflection device or an illumination device are disclosed.
