Abstract

A light for room illumination has a space (5) with one or more partly reflecting walls (11), and the first wall (9) is partly transparent and has a light-decoupling zone. A linear light-refracting structure is provided on the first wall (11) and extends parallel to the 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 shaped light refracting elements extending parallel to the light source, and possess a tapering shape in the cross-section in one plane normal to the defining line.
