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.

Light deflection device, method for manufacturing a light deflection device and illumination device

A decorative light guide element having a decorative surface made of segments, at least one of which is a decorative light guide element, and method for producing such a decorative light guide element with illumination and decorative functions. To provide a decorative light guide element, which facilitates illumination independent of the decoration but also has visible decoration when deactivated, provision is made for the decorative light guide element to have a planar light guide element and a light source for coupling light into the light guide element. On a first side of the light guide element, a planar decorative element and, on the opposite side, a microstructure layer for coupling out the light of the light guide element are arranged. An intermediate layer is arranged between the light guide and decorative elements. The intermediate layer having a lower refractive index than the material of the light guide element.

Decorative light guide element

A device and method for producing light-exposed structures on a workpiece having a light-sensitive surface. An optical unit includes a light source and a diffraction grating for producing a strip-shaped illumination pattern having strips extending in a longitudinal direction and having a pattern width extending transversely. A device moves the surface of the workpiece and optical unit relative to each other according to a path sequence, which includes movement longitudinal paths to produce a first and second light-exposed structure having strips, which is oriented parallel to each other on the workpiece surface. The movement paths are mutually spaced apart by less than the pattern width and the light-exposed structures overlap in such a way that strips of the light-exposed structures lie on each other. To obtain good light exposure of the surface by the illumination pattern, the diffraction grating is set oblique to the surface of the workpiece that is light-exposed by the illumination pattern.
