Publication number: 20150369447Abstract: Various embodiments may relate to a lighting arrangement and a method for producing or for operating the same. The lighting arrangement includes a plurality of radiating faces, on which light may be emitted in each case as a beam. Owing to this “direction competence”, the lighting arrangement may not only reproduce a two-dimensional image of an illumination pattern, but it may emit light directionally and thus reproduce a luminance distribution of the illumination pattern.Type: ApplicationFiled: January 30, 2014Publication date: December 24, 2015Inventors: Bakuri Lanchava, Simon Schwalenberg, Julius Muschaweck
