Die Projektionswand, bestehend aus einer flächigen Trägerstruktur und beidseitig aufgetragenem transluzentem Projektionsmaterial, ist dadurch gekennzeichnet, daß
  • 1. das auf die Fläche (G) auftreffende Licht zum Teil reflektiert wird, aber auch Licht durch die Öffnungen (C) in der Trägerstruktur (J) auf die projektions­ abgewandte Fläche (H) hindurchscheint, wodurch das aufprojezierte Bild auf der projektionsabgewandten Seite in Lichteffekte abhängig von Größe und Form der Öffnungen (C) aufgeteilt wird;
  • 2. dieses Prinzip auch umgekehrt funktioniert, d. h. daß die Projektionsfläche (H) der Projektion zugewandt, und die Projektionsfläche (G) projektions­ abgewandt ist;
  • 3. die Trägerstruktur (J) zwischen den Projektionsflächen gitterförmig (Fig. 1), oder flächenförmig (Fig. 2) sein kann;
  • 4. die Trägerstruktur (J) flächeneben und auch gewölbt sein kann;
  • 5. sich durch verschiedene Abmessungen der Öffnungen (C) in der Trägerstruktur (J), der Längen (A), (B) und den Abständen (D), (E), (F) verschiedene Lichteffekte auf der projektionsabgewandten Seite erzielen lassen;
  • 6. die Öffnungen (C) in der Trägerstruktur (J) in Form und Anordnung auf der Fläche der Trägerstruktur (J) frei wählbar sind;
  • 7. Materialität und Farbgebung der verwendeten Elemente frei wählbar ist.
  • 8. das aufprojezierte Licht sowohl stehende Bildinformation (Licht, Dia), als auch bewegte Bildinformation (Videoprojektor, Laserlicht, bewegtes Licht, Fernseher.- Monitorlicht) sein kann.
The projection screen, consisting of a flat support structure and translucent projection material applied on both sides, is characterized in that
  • 1. the light striking the surface (G) is partially reflected, but also light shines through the openings (C) in the support structure (J) onto the projection-facing surface (H), whereby the projected image on the side facing away from the projection in Lighting effects depending on the size and shape of the openings (C) is divided;
  • 2. This principle also works in reverse, ie the projection surface (H) faces the projection and the projection surface (G) faces away from the projection;
  • 3. the support structure (J) between the projection surfaces can be lattice-shaped ( Fig. 1) or flat ( Fig. 2);
  • 4. the support structure (J) is flat and can also be curved;
  • 5. Different dimensions of the openings (C) in the support structure (J), the lengths (A), (B) and the distances (D), (E), (F) can be used to achieve different lighting effects on the side facing away from the projection;
  • 6. the openings (C) in the support structure (J) are freely selectable in shape and arrangement on the surface of the support structure (J);
  • 7. Materiality and coloring of the elements used is freely selectable.
  • 8. the projected light can be both standing image information (light, slide) and moving image information (video projector, laser light, moving light, television monitor light).
