Abstract

The control circuit may be integrated into the window and a lithium battery may replace at lower cost the use of a sensor and rechargeable battery. Alternatively, the user may control the system through manual control or a program in a box either near to or at a distance from the window. The liquid crystals may be reflective on one of the two surfaces and the support for the window may take various forms or colours.

Description

La présente invention concerne un dispositif capable de contrôler la quantité de rayons lumineux qui passent à travers un support en verre ( vitre ). The present invention relates to a device capable of controlling the quantity of light rays which pass through a glass support (pane).

Le dispositif selon l'invention permet de modifier l'opacité de la vitre en modulant la position de cristaux liquides, réfléchissant sur une ou deux faces, qui sont incorporés dans la vitre; il agit donc comme un rideau électronique. The device according to the invention makes it possible to modify the opacity of the glass by modulating the position of liquid crystals, reflecting on one or two faces, which are incorporated in the glass; it therefore acts as an electronic curtain.

Les cristaux se présentent perpendiculairement au trajet lumineux, bloquent ce dernier, voire le rejettent en partie ou en totalité. Les cristaux se présentent parallèlement au trajet lumineux, ce dernier passe plus facilement à travers la vitre. The crystals appear perpendicular to the light path, block the latter, or even reject it in part or in whole. The crystals appear parallel to the light path, which passes more easily through the glass.

La technique utilisée est celle des écrans à cristaux liquides, simplifiée, car l'adressage de la polarisation de chacun des cristaux demande un matriçage élémentaire par ligne ou en bloc de lignes. L'utilisation des cristaux réfléchissant permet de mieux gérer les échanges de températures de part et d'autre de l'écran. The technique used is that of liquid crystal screens, simplified, because the addressing of the polarization of each of the crystals requires an elementary matrixing by line or in block of lines. The use of reflective crystals makes it possible to better manage the exchange of temperatures on either side of the screen.

Le dispositif agit également comme écran thermique, maintenant l'énergie à l'intérieur d'espaces fermés ou empêchant l'énergie solaire de pénétrer. Le support vitré peut être de forme, de dimension, de teinte variable selon les différentes applications. The device also acts as a heat shield, keeping energy inside closed spaces or preventing solar energy from entering. The glazed support can be of shape, dimension, variable shade according to the different applications.

Un boîtier électronique de contrôle permet à l'utilisateur de faire varier la position des cristaux selon ses besoins, manuellement ou à distance, programmable ou non.An electronic control unit allows the user to vary the position of the crystals according to his needs, manually or remotely, programmable or not.

Ce boîtier ainsi que toute l'électronique nécessaire peut être intégré dans la surface vitrée.This box and all the necessary electronics can be integrated into the glass surface.

Un petit capteur d'énergie solaire, un accumulateur électrique (batterie rechargeable) peuvent également y être adjoints afin d'avoir une autonomie complète.A small solar energy collector, an electric accumulator (rechargeable battery) can also be added to it in order to have complete autonomy.

Une pile au lithium peut remplacer le capteur et la batterie rechargeable pour un coût inférieur.A lithium battery can replace the sensor and the rechargeable battery at a lower cost.

A titre d'exemple non limitatif cette invention peut être applicable aux domaines suivants : contrôle de la lumière et de la chaleur à l'intérieur de bâtiments ( portes, fenêtres ), de véhicule ( effet de serre ), ou autres constructions. By way of nonlimiting example, this invention can be applicable to the following fields: light and heat control inside buildings (doors, windows), vehicles (greenhouse effect), or other constructions.

Le dispositif selon l'invention est particulièrement destiné à remplacer électroniquement une grande majorité de rideaux mécaniques doublant une surface vitrée.  The device according to the invention is particularly intended to electronically replace a large majority of mechanical curtains doubling a glazed surface.
