Abstract

With the liquid crystal sun protection concept, double-walled glass plates (9) are used, between which an adhesive foil (10) and a liuquid crystal module (Y) are integrated. A plate frame (1) and a liq. crystal frame (2) are involved, with a linearly polarisign analysis unit (8), organic substance (4, light-permeable, electrically conductive coating (5, 6) togehter with two glass coating carriers (7), current leads (11), an AC source (12), and a switch (13). In the rest state, the switch (13) is open, the polarising filters (3, 8) are arranged parallel, and the organic substance (4) is not electrically activated. With pole filters with 42 per cent light permeability approximately 17.64 per cent of the light passes through the liq. crystal layer. When no light is required, the switch (13) is closed, the organic substance (4) is electrically activated and the light allowed through by the polarising unit is polarised. The light is turned through 90 deg. and can then no longer pass through the analyst unit. In this way, a 100 per cent sun protection is achieved. USE - Controllable sun protection for use in buildings, vehicles boats etc.

Description

PSS beruht auf der Anwendung von Polarisationsfolien in doppelwandigen Glasscheiben, durch die der Innenraum eines Fahrzeugs oder eines Gebäudes bei Bedarf vor Sonneneinstrahlung geschützt werden kann. Der zu schützende Bereich kann entweder vollflächig oder nur ein streifenförmiger Bereich sein. Zwei Versionen mit zwei Konzepten werden dargestellt: Das erste Konzept befaßt sich mit der Anwendung der Flüssigkristall-Technik und stellt den streifenförmigen, polarisierenden Bereich dar, während das zweite Konzept ein vollflächiges Beispiel darstellt, das sich mit einem mechanisch bewegten Analysator befaßt. Diese Erfindung bietet einen elektrisch einschaltbaren Sonnenschutz an, eine nicht nur elegante Lösung, sondern auch funktionell flexibel. Die Anwendung ist überall dort möglich, wo ein einschaltbarer Sonnenschutz eine Notwendigkeit ist, z. B. im Fahrzeug, Wohnwagen, Wohnmobil, Boot, Schiff, Flugzeug, in der Eisenbahn, Straßenbahn, im Büro, in der Dunkelkammer etc.PSS is based on the use of polarizing foils in double-walled glass panes through which the interior a vehicle or a building if necessary Sun exposure can be protected. The too protective area can either be full-surface or only one strip area. Two versions with two Concepts are presented: The first concept is concerned with the application of liquid crystal technology and represents the stripe-shaped, polarizing area while the second concept is a full-scale Example that deals with a mechanical moving analyzer. This invention offers one electrically switchable sun protection, not only one elegant solution, but also functionally flexible. The Application is possible wherever a switchable Sun protection is a necessity, e.g. B. in the vehicle, Caravan, camper, boat, ship, plane, in the Railway, tram, in the office, in the dark room etc.

Flüssigkristall-Sonnenschutz (FKS):Liquid crystal sun protection (FKS):

Laut Abb. 1 und 2 besteht das FKS-Konzept aus doppelwandigen Glasscheiben 9), zwischen denen eine Klebefolie 10) und ein Flüssigkristallmodul Y) integriert sind. Das FK-Modul Y) besteht aus folgenden Komponenten:
Scheibenrahmen 1), FK-Modulrahmen 2), linear polarisierendem Analysator 3), linear polarisierendem Polarisator 8), polarisierender, organischer Substanz 4), lichtdurchlässiger, elektrisch-leitender Beschichtung 5) und 6) und zwei Glas-Beschichtungsträger 7), Stromleitungen 11), einer Wechselstromquelle 12) und einem Schalter 13). According to Fig. 1 and 2, the FKS concept consists of double-walled glass panes 9 ), between which an adhesive film 10 ) and a liquid crystal module Y) are integrated. The FK module Y) consists of the following components:
Window frame 1 ), FK module frame 2 ), linearly polarizing analyzer 3 ), linearly polarizing polarizer 8 ), polarizing, organic substance 4 ), translucent, electrically conductive coating 5 ) and 6 ) and two glass coating carriers 7 ), power lines 11 ), an AC power source 12 ) and a switch 13 ).

Funktionsweise:Functionality:

Im Ruhezustand ist der Schalter 13) offen, die Polarisationsfilter 3) und 8) sind parallel angeordnet und die organische Substanz 4) nicht elektrisch aktiviert. Bei Polfiltern mit 42% Lichtdurchlässigkeit passiert ca. 17,64% des Lichtes die FK-Scheibe. Falls kein Licht erwünscht ist, wird Schalter 13) geschlossen, die organische Substanz 4) wird elektrisch aktiviert und somit wird das vom Polarisator durchgelassene Licht polarisiert. Das Licht wird um 90° gedreht und kann den Analysator nicht mehr passieren. Dadurch wird 0% Licht durchgelassen - ein 100%iger Sonnenschutz entsteht. Diese Anwendung ist besonders für die Windschutzscheibe von Fahrzeugen geeignet, obwohl auch Seitenscheiben nach Wunsch vollflächig mit FKS ausgerüstet werden können. Bei dieser Anwendung besteht die Möglichkeit, die voll in der Sonne stehenden Fahrzeuge fast vollständig vor der Sonneneinstrahlung zu schützen. In the idle state, the switch 13 ) is open, the polarization filters 3 ) and 8 ) are arranged in parallel and the organic substance 4 ) is not electrically activated. In polarizing filters with 42% light transmission, approx. 17.64% of the light passes through the FK disc. If no light is desired, switch 13 ) is closed, the organic substance 4 ) is activated electrically and thus the light transmitted by the polarizer is polarized. The light is rotated by 90 ° and can no longer pass through the analyzer. This allows 0% light to pass through - 100% sun protection is created. This application is particularly suitable for the windshield of vehicles, although side windows can also be fully equipped with FKS if desired. With this application it is possible to almost completely protect the vehicles standing completely in the sun from the sun.

Linearisierter Polarisations-Sonnenschutz (LPS):Linearized polarization sun protection (LPS):

Laut Abb. 3, 4 und 5 besteht das LPS-Konzept aus folgenden Komponenten: dem Verstellmechanismus 1), der seinerseits aus dem Rahmen 5), dem Verstellrad 9), der Verstellschraube 10) und dem Analysatorträger 11) besteht; der beweglichen Lagerung 2), bestehend aus dem Gelenkhebel 4) und zwei Bolzen 3); der Fensterscheibe 6); dem Polarisator 7) und dem Analysator 8). Die Polarisationsfilter 7) und 8) bestehen aus einer Reihe von schmalen Streifen mit Breite (x), die wiederkehrend in verschiedenen Polarisationsrichtungen geschnitten sind. Für drei Verdunkelungsstufen ist der erste Streifen z. B. waagerecht (0°) polarisierend, gefolgt von einem 45° polarisierenden Streifen und dann einem senkrecht (90°) polarisierenden, gefolgt von einem 135° polarisierenden Streifen und dann wieder waagerecht usw.According to Figure 3, 4 and 5, the LPS concept of the following components: the adjusting mechanism 1), which in turn consists of the frame 5), the adjustment wheel 9), the adjusting screw 10) and the Analysatorträger 11);. the movable bearing 2 ), consisting of the articulated lever 4 ) and two bolts 3 ); the window pane 6 ); the polarizer 7 ) and the analyzer 8 ). The polarization filters 7 ) and 8 ) consist of a series of narrow strips with width (x) which are cut repeatedly in different polarization directions. For three darkening levels, the first strip is e.g. B. Horizontal (0 °) polarizing, followed by a 45 ° polarizing stripe and then a vertical (90 °) polarizing, followed by a 135 ° polarizing stripe and then again horizontally etc.

Funktion:Function:

Wenn der Analysator den Polarisator überdeckt (Abb. 1 -a-), dann werden jeweils zwei parallel ausgerichtete Polarisationsfolien pro Streifenpaar simuliert und die Scheibe wird lichtdurchlässig. Für Folien mit 42% Transmittanz entspricht diese Stellung einer Lichtdurchlässigkeit von 17,6%. Wenn aber der Analysator um einen Streifen, also um Abstand x versetzt wird (Abb. 2 -b-), entspricht die versetzte Überdeckung einer Drehung des Analysators um 45°, somit wird die Scheibe dunkler und eine Transmittanz von 8,8% wird simuliert. Abb. 3 -c- entspricht einer Verschiebung des Analysators um den Abstand 2x · (2-Streifen) nach rechts, dadurch werden sämtliche Streifen um 90° gekreuzt, d. h. entweder 0°/90° oder 45°/135° überdecken sich. Diese letzte Stufe simuliert die Drehung des Analysators gegenüber dem Polarisator um 90°. Eine vollständige Verdunkelung wird erreicht und damit ein 100%iger Sonnenschutz. Die Breite (x) aller Streifen ist frei wählbar, jedoch sollte ein möglichst kleines Maß angestrebt werden, damit der Fensterrahmen kompakt bleibt. Sogar Zwischenstufen, hier 45°-Schritte, sind wählbar. 15°-Abstufungen würden eine fast stufenlose Verdunkelung ermöglichen - sind aber nicht unbedingt erforderlich. Obwohl die Verstellung mittels Schrauben als Beispiel angegeben ist, sind andere Mechanismen möglich, u. a. Elektro-Bimetall, Hubmagnet, Schrittmotor, Hydraulik, Pneumatik usw. Eine streifenförmige Ausführung für die Windschutzscheibe ist ebenfalls möglich.If the analyzer covers the polarizer ( Fig. 1 -a-), then two parallel polarizing foils per pair of strips are simulated and the pane becomes translucent. For films with 42% transmittance, this position corresponds to a light transmission of 17.6%. However, if the analyzer is offset by a stripe, i.e. by a distance x ( Fig. 2 -b-), the offset overlap corresponds to a rotation of the analyzer by 45 °, so that the pane becomes darker and a transmittance of 8.8% is simulated . Fig. 3 -c- corresponds to a shift of the analyzer by the distance 2x · (2-stripes) to the right, this means that all stripes are crossed by 90 °, ie either 0 ° / 90 ° or 45 ° / 135 ° overlap. This last stage simulates the rotation of the analyzer in relation to the polarizer by 90 °. Complete darkening is achieved and thus 100% sun protection. The width (x) of all strips is freely selectable, however, the smallest possible dimension should be sought so that the window frame remains compact. Even intermediate levels, here 45 ° steps, can be selected. 15 ° gradations would allow almost continuous darkening - but are not absolutely necessary. Although the adjustment by means of screws is given as an example, other mechanisms are possible, including electro-bimetal, lifting magnet, stepper motor, hydraulics, pneumatics, etc. A strip-shaped design for the windshield is also possible.
