摘要： The invention relates to a device for guiding light consisting of at least one partially translucent planar material. Said device comprises a planar upper side, which is provided with optically active surface structures for guiding light and/or diffusing light. In addition, an optically switchable coating is provided at least in partial areas of the surface structures or the inventive device comprises at least two indirectly or directly opposite surface upper sides, of which one has optically active surface structures for guiding light and/or diffusing light, and the other provides an optically switchable coating that covers at least portions of the surface upper side.

摘要： The invention relates to a sun protection device comprising at least one flat optical element (F) consisting of an at least partially transparent material and having two sides facing each other, one (E) of said sides being embodied in a non-structured flat manner, and the other (S) comprising parallel, linearly extending prismatic structural elements (SE) which periodically repeat themselves in the lateral direction. The structured side (S) comprises a surface (O) which is at least largely coparallel in relation to the unstructured flat side (E), the structural elements (SE) projecting past said surface. The inventive device is characterised in that the structural elements (SE) respectively comprise a triangular cross-sectional surface having a lateral edge (C) and two lateral flanks (A, B) which protrude above the surface, the lateral flank (A) being associated with a defining surface (A*) and the lateral flank (B) being associated with a defining surface (B*). Furthermore, at least two adjacent structural elements are laterally separated from each other by a section (D) of the surface (O), the lateral flank (A) forms an angle 90°-α with the surface, and forms an angle α + β with the lateral flank (B), and the lateral flank (B) forms an angle 90°-β with the surface.

摘要： The invention relates to a sun protection device that has a plurality of segments that are spaced apart from one another parallel to their longitudinal direction and that are received so as to be rotatable about their longitudinal axis. The segments have respective segment top surfaces on which a plurality of optical concentrator structure elements from an at least partially transparent dielectric material, so-called CPCs ( C ompound P arabolic Concentrators), are provided. Said concentrators have a surface of incidence and one planar or curved receiving surface and are oriented with their receiving surface toward the segment top surface. The invention is characterized in that the segment top surface, at an angle to its longitudinal direction, is at least partially curved or edged, the segment top surface is reflecting or opaque, and the CPCs adjoin the segment top surface with their receiving surface directly or across at least one coupling layer or are spaced apart and disposed opposite the segment top surface.
