摘要：A light for room illumination has a space (5) with one or more partly reflectingwalls (11), and the first wall (9) is partly transparent and has a light-decoupling zone. Alinear light-refracting structure is provided on the first wall (11) and extends parallel tothe light-source and has a tapering cross-section in a plane normal to the line defining it.
The sides of the cross-section approximately lie in one region from 100 deg. to 130 deg.while the second wall (7) of the light transparent zone has a structure of linearly shapedlight refracting elements extending parallel to the light source, and possess a taperingshape in the cross-section in one plane normal to the defining line.
