Description
Die Erfindung betrifft eine Verglasung mit schaltbaren optischen Eigenschaften, die im transparenten Zustand eine erhöhte Reflektion in eine Richtung aufweist und somit eine vollständige Privatsphäre gewährleistet.The invention relates to glazing with switchable optical properties, which in the transparent state has increased reflection in one direction and thus ensures complete privacy.
Es sind Verglasungen bekannt, die eine funktionelle Schicht enthalten, mittels derer die optischen Eigenschaften der Verglasung verändert werden können. Ein Beispiel hierfür sind elektrochrome Verglasungen, die eine elektrochemisch aktive Schicht zwischen zwei transparenten Flächenelektroden enthalten. Die Transmissionseigenschaften der aktiven Schicht können durch die an die Flächenelektroden angelegte Spannung elektrisch geschaltet werden.Glazings are known which contain a functional layer by means of which the optical properties of the glazing can be changed. An example of this is electrochromic glazing, which contains an electrochemically active layer between two transparent surface electrodes. The transmission properties of the active layer can be switched electrically by the voltage applied to the surface electrodes.
Verglasungen mit schaltbaren optischen Eigenschaften können beispielsweise als Fensterscheiben von Gebäuden verwendet werden. Dazu zählt die Polymer Dispersed Liquid Crystal (PDLC)-Technologie, die häufig in Gebäuden verwendet wird. Dabei handelt es sich zum Beispiel um einen aktiven Film, der von einem transparenten zu einem transluzenten, durchscheinenden, milchigen Zustand umschalten kann. Die PDLC Technologie ermöglicht bei Autogläsern interessante Anwendungen. Die PDLC Technologie kann bei laminierten Schiebedächern verwendet werden, um mechanische Rollläden zu ersetzen. Die PDLC Technologie kann auch für Sonnenblenden in Windschutzscheiben verwendet werden, um zu vermeiden, dass man geblendet wird.Glazing with switchable optical properties can be used, for example, as window panes in buildings. This includes polymer dispersed liquid crystal (PDLC) technology, which is often used in buildings. For example, this is an active film that can switch from a transparent to a translucent, translucent, milky state. PDLC technology enables interesting applications in car glasses. PDLC technology can be used on laminated sunroofs to replace mechanical shutters. PDLC technology can also be used for sun visors in windshields to avoid being blinded.
Im ausgeschalteten Zustand ist das Glas undurchsichtig, daher milchig und der Passagier kann nicht von innen nach außen schauen und Personen von außen können nicht nach innen schauen. Im eingeschalteten Zustand ist das Glas transparent. Der Passagier kann von innen nach außen und Personen von außerhalb können nach innen schauen. Gegenwärtig werden reflektierende Schichten verwendet, um den RIR und nicht um das RL zu erhöhen. RL (Reflexionsvermögen für sichtbares Licht, je höher der RL ist, desto spiegelähnlicher ist es) RIR (Reflexionsvermögen für Infrarot, dargestellt durch das RE, die Gesamtenergiereflexion).When switched off, the glass is opaque, therefore milky, and the passenger cannot look inside and people outside cannot look inside. The glass is transparent when switched on. The passenger can look inside and people outside can look inside. Reflective layers are currently used to increase the R IR and not the R L. R L (reflectivity for visible light, the higher the R L , the more mirror-like it is) R IR (reflectivity for infrared, represented by the R E , the total energy reflection).
Beschichtungswerte für gewöhnliche Beschichtungen sind in dieser Tabelle aufgeführt.
Es hat sich gezeigt, dass die übliche Beschichtung mit PDLC nicht ausreicht, um eine vollständige Privatsphäre zu gewährleisten.It has been shown that the usual coating with PDLC is not sufficient to guarantee complete privacy.
Die Aufgabe der vorliegenden Erfindung ist es, eine verbesserte Verglasung mit schaltbaren optischen Eigenschaften bereitzustellen, die im transparenten Zustand eine erhöhte Reflektion aufweist und somit eine vollständige Privatsphäre gewährleistet.The object of the present invention is to provide improved glazing with switchable optical properties, which in the transparent state has an increased reflection and thus ensures complete privacy.
Die Aufgabe der vorliegenden Erfindung wird erfindungsgemäß durch eine Verglasung mit schaltbaren optischen Eigenschaften und mit reflektierender Beschichtung gemäß dem unabhängigen Anspruch 1 gelöst. Bevorzugte Ausführungen gehen aus den Unteransprüchen hervor.The object of the present invention is achieved according to the invention by glazing with switchable optical properties and with a reflective coating according to
Die Aufgabe der vorliegenden Erfindung wird insbesondere durch eine Verglasung mit einer Scheibenanordnung gelöst, die mindestens umfasst:
- - ein transparentes Substrat mit einer Außenfläche und einer Innenfläche,
- - ein transparentes Substrat mit einer Außenfläche und einer Innenfläche,
- - eine schaltbare Schicht,
- - eine für IR + sichtbares Licht reflektierende Schicht,
- a transparent substrate with an outer surface and an inner surface,
- a transparent substrate with an outer surface and an inner surface,
- - a switchable layer,
- - a layer reflecting for IR + visible light,
Um den Mangel an Privatsphäre zu verringern, wird gemäß der vorliegenden Erfindung eine reflektierende Schicht mit hohem RL und bevorzugt zusätzlich mit RIR hinzugefügt. Durch die Erhöhung von RL wird auch ein erhöhter RIR erreicht. Gemäß der vorliegenden Erfindung ist es ein Vorteil, reflektierende Beschichtung mit hohem RL zu verwenden. Die hier vorgeschlagene Beschichtung erzeugt einen Einwegspiegel.In order to reduce the lack of privacy, according to the present invention a reflective layer with high R L and preferably additionally with R IR is added. Due to the increase of R L and R, an increased IR is achieved. According to the present invention, it is an advantage to use high R L reflective coating. The coating proposed here creates a one-way mirror.
