The light has a cavity (5) with a light decoupling region, a transparent wall (9), a structure of linear light-refracting elements, a partly transparent wall (7) and a partly reflecting wall (11) that is arranged opposite to the transparent wall. A linear light source (3) is arranged outside the cavity in such a manner that light of the light source is coupled into the cavity through the transparent wall and is decoupled from the cavity through the light decoupling region. The transparent wall exhibits the structure of light-refracting elements, which exhibits a form of cone or truncated cone. |
