Optisches Bauelement sowie dessen Verwendung

(A1) Die Erfindung betrifft den Transport von sichtbarem Licht durch Begrenzungen, wie z. B. durch Waende, Daecher, Fassaden oder Gehaeuse, sowie Ummantelungen und Umhuellungen von Geraeten, Sensoren, Reaktoren etc., die Innen- von Aussenraeumen trennen. Die Begrenzungen haben dabei die Aufgabe, Innenraeume von Gebaeuden, Bauwerken oder das Innere von Geraeten, Sensoren, Reaktoren oder auch Fahrzeugen, Schiffen vor Naesse, Kaelte, Solarstrahlung, mechanischen Einwirkungen, wie z. B. Explosionen, Erdbeben, Wirbelstuermen, elektromagnetischer und radioaktiver Strahlung oder auch chemischen Einfluessen wirksam zu schuetzen. Die optische Verbindungstechnik stellt ebenfalls ein Anwendungsgebiet der Erfindung dar.

DE 102009019635 A1 UPAB: 20101122 NOVELTY - The element has an optically transparent substrate (1) comprising a light incident surface (4) and a light emission surface (5). Optically diffuse reflecting segments (2, 3) are arranged on the surfaces of the substrate, where the two segments are displaced to each other. The substrate is made of quartz glass, low iron glass, acrylic glass, plastics, polycarbonates, polyesters, polyvinyl chloride or optically transparent polymers, where thickness (D2) of the substrate ranges between 1 and 3 cm. DETAILED DESCRIPTION - The segments are made of a porous Teflon (RTM: PTFE) with reflected color materials that are made of barium sulfate, titanium dioxide, aluminum pastes, silicon nitride, ceramics, phosphors, inorganic pigments, fluorescent materials such as naphthalimides, stilbene or styryl or phosphorescent materials such as rare-earth metals, phosphates, silicates, germanates, oxides, sulfides, oxysulfides, selenides, sulfoselenides, vanadates, niobates, arsenates, tantalates, wolframates, molybdates, halogenates, nitrides, borates, aluminates, gallates, or halogenides. An INDEPENDENT CLAIM is also included for a device comprising a boundary that encloses an internal area. USE - Optical element for use as a translucent delimitation of a roof and a wall of a building, cover, roof, housing and shroud of a device, covering of a traffic infrastructure and a tunnel, reactor, casing of a ship and a detector, and for insulating solar energy in the building, a greenhouse and an animal stall (all claimed). Can also be used for a sensor and an airplane. ADVANTAGE - The optically diffuse reflecting segments are arranged on the surfaces of the substrate, where the two segments are displaced to each other, thus enabling indirect lighting of an interior part of a place e.g. building.
