摘要

An apparatus is described for light deflection, as well as - mask for the stationary use in the case of a translucent building façade for the targeted illumination of an interior space with at least a translucent optical element, which has a planar light entrance side as well as a light emitting side, from a first curved boundary surface as well as at least of a second boundary surface is limited, with the curvature of the first interface is designed in such a way that light beams in the form of a first solid angle area to the light entrance side and to couple in the optical element within the path of the total reflection at the first interface to the region of the second boundary surface to be concentrated and that light beams, which consists of a second solid angle area to the light entrance side and to couple in the optical element, by means of the first interface emerge from the optical element. Dollars a the invention is characterized in that the second interface is likewise continuously curved and that the first and second interface seamlessly and with a continuous curvature adjoin one another.
