Abstract (en)
[origin: WO2016207294A1] The invention relates to an indirect lighting arrangement (2, 2.1, 2.2, 2.3, 2.4, 2.5) comprising at least one cylindrical waveguide (4). At least one end (12.1, 12.2) of the cylindrical waveguide (4) is designed to couple light from a first light source (1) into the cylindrical waveguide (4), and the lateral surface (10) of the cylindrical wave guide (4) has a coupling section (6) which is designed to optically couple the cylindrical waveguide (4) to an arrangeable plate-shaped waveguide (16). At least the coupling section (6) has at least one holographic optical element (8) which is designed to emit light from the cylindrical waveguide (4) into the arrangeable plate-shaped waveguide (16).
