Abstract

The liq. crystal cell is used to provide a required darkening or colouring effect. It comprises a flat liq. crystal element (1) attached to the surface of the window or glass panel, coupled to a voltage supply (4) which provides an electrical field determining its transparency or colour. The required colour is selected via a colour selection button and the light transparency is selected via a dimming switch (2), both the latter connected in series between the voltage supply (4) and the liq. crystal element (1). ADVANTAGE - Eliminates need for solar blinds in conservatory or greenhouse etc.

Beschreibung description

Dort wo es gilt, Räume zu verdunkeln oder farbig zu gestalten, ist es üblich, Sonnenrolladen oder farbige Folien zu benützen. Where it is necessary to darken rooms or to design them in color, it is common to use sun blinds or colored foils.

Hier will die Erfindung Abhilfe schaffen. Ihre Aufgabe ist, eine Einrichtung vorzuschlagen, mit der man Glaswände und Fenster in Gebäude beliebig verfärben oder verdunkeln, sowie Räume gegen Sonnenstrahlen schützen und Lichtdurchlässigkeit automatisch oder manuell einstellen kann. Die Lösung dieser Aufgabe ist im Patentanspruch definiert. The invention seeks to remedy this. Your task is to propose a device with which you can discolor or darken glass walls and windows in buildings as well as protect rooms against sun rays and adjust light transmission automatically or manually. The solution to this problem is defined in the claim.

Sehr nützlich ist die Erfindung im Glashäuschen, Wintergarten und dort, wo es wichtig ist, eine konstante Lichtstärke zu halten. The invention is very useful in the glass house, conservatory and where it is important to maintain a constant light intensity.

Bedeutung hat diese Einrichtung bei Risikoschaltern, wo es jetzt möglich ist, in Bruchteilen von Sekunden das Personal von der Öffentlichkeit optisch zu isolieren. This facility is important for risk switches, where it is now possible to optically isolate personnel from the public in a fraction of a second.

Der Vorteil der Erfindung ist darin zu sehen, dass die Einrichtung nachträglich an eine bereits vorhandene Glasscheibe montiert werden kann. The advantage of the invention is the fact that the device can be retrofitted to an existing glass pane.

Die einzige Figur zeigt ein Ausführungsbeispiel der Erfindung, in der Figur erkennt man neben einem Flüssigkristallzellen-Flächenelement 1 sowohl einen Dämmerungsschalter 2 wie auch eine Farbwahltaste 3. Diese Schaltanordnung ist an eine Spannungsversorgung 4 angeschlossen. The single figure shows an embodiment of the invention, in the figure you can see not only a liquid crystal cell surface element 1 but also a twilight switch 2 and a color selection button 3. This switching arrangement is connected to a voltage supply 4.
