Leuchte mit einem um einen Mittelpunkt symmetrisch angeordneten Hohllichtleiter und symmetrischer Lichteinstrahlung, insbesondere Rundleuchte

摘要

The light has a non-rectangular housing and/or light output surface. Light radiated into the hollow volume of a hollow light conductor is coupled out to the output surface by a coupler with a light refractive structure of linear elements. A light input device is oriented so light radiated into the hollow volume and incident directly on the coupler is predominantly incident in a direction perpendicular to a line defining the structural elements. The light has a non-rectangular housing and/or a non rectangular light output surface (3). Light is radiated into the hollow volume (12) of a hollow light conductor from one or more sources and is coupled out to the output surface by a transparent output coupler with a boundary between two media of different refractive indices with a light refractive structure (30) of linear elements. The light input device (13) is oriented so that light radiated into the hollow volume and incident directly on the output coupling device (16) is predominantly incident in a direction perpendicular to the line defining the structural elements.
