  • the light exit side D is provided with a coating E which blocks the radiation either absorbed or reflected back into the inlet half-space B.
  • the invention has for its object a device for redirecting light and blanking for stationary use with a translucent Building facade for targeted lighting of an interior with at least one translucent optical element, according to the preamble of claim 1 to further develop in such a way that the linear or optical elements arranged in an array should exist therethrough.
  • it is a simple and inexpensive device for light suppression as well as specifying light deflection.
  • a device for light deflection and suppression is for stationary use with a translucent building facade for targeted Illumination of an interior with at least two translucent optical Elements formed according to the preamble of claim 1 such that the optical elements are arranged next to each other in such a linear or array-like manner, that the light exit sides of the individual optical elements from each other are spaced, and that in the between the light exit sides intermediate area forming a light reflecting or at least partially light absorbing means is provided.
  • the light reflecting or at least partially or partially light-absorbing agents By providing the light reflecting or at least partially or partially light-absorbing agents, not as in the case of the German patent application DE 196 13 222 A1 directly in the area of the light exit side, but in the Intermediate areas that extend from the respective light exit sides of the linear or optical elements arranged in an array are included specifically hiding that light on the light entry side of the individual optical elements from the second solid angle range.
  • the light entry side of the optical elements arrives almost unhindered Light exit side at which it emerges from the optical element accordingly can. This ensures that the optical element at least on the surfaces the light exit side is completely transparent, provided that the The light entry and exit sides are flat and parallel.
  • Figure 1 shows a longitudinal section through four linearly arranged side by side optical elements C, the light entry sides A each in a uniform Level.
  • the light entry sides A are free Light exit sides D arranged, none compared to the prior art have light-absorbing layer. Rather are in the intermediate areas between the light exit sides D light-absorbing or reflecting means, For example, provided in the form of diaphragms BL, the light from the side of the Light entry side falls on the screens BL, absorb or into the light entry space reflect back again. In particular, this applies to those light components that affect the Light entry sides of the optical elements from the second solid angle range come to mind. If, on the other hand, light fails within the first solid angle range, that is area B (see FIG.
  • the essential advantage of the optical elements shown in FIG. 1 is the possibility a direct view through the optical elements, at least in the area of their Light exit surfaces D.
  • This relationship is shown graphically in FIG. at vertical arrangement of a plurality of arrayed optical elements for example within a window element, it is for an observer in the interior I possible, through the light exit sides of the respective optical elements to the outside to see (passband).
  • sunlight falls on the outside Light entry sides of the optical elements within the second Solid angle range, the so-called Ausbelend Scheme, this is Sunlight hidden by the presence of the BL aperture.
  • FIG. 5 shows a further embodiment for a linear or array-shaped one Arrangement consisting of a plurality of optical elements C shown.
  • the individual optical elements C have a uniform light entry side A and are with their respective light emission sides with a transparent Carrier substrate T connected.
