Title (EN) SWITCH ELEMENT COMPRISING A LIQUID-CRYSTALLINE MEDIUM
(FR) ÉLÉMENT COMMUTATEUR COMPRENANT UN MILIEU CRISTAL LIQUIDE
Abstract:
(EN) The present invention relates to a switch element, which is thermo-responsive and which switches between a less transmissive state for radiant energy and a more transmissive state for radiant energy, and which comprises a liquid-crystalline medium. The invention furthermore relates to the use of the switch element for the regulation of radiant energy flow between interior spaces and the environment and for the regulation of the temperature of interior spaces. The invention furthermore relates to a liquid-crystalline medium, characterised in that it comprises a compound of the formula (I), in particular for use in the switch elements according to the invention.
(FR) Cette invention concerne un élément commutateur, qui est thermoréactif et fait passer une énergie rayonnante d'un état moins émissif à un état plus émissif, et qui comprend un milieu cristal liquide. Cette invention concerne, en outre, l'utilisation dudit élément commutateur pour réguler le flux d'énergie rayonnante entre des espaces intérieurs et l'environnement et pour réguler la température d'espaces intérieurs. Un milieu cristal liquide, caractérisé en ce qu'il comprend un composé de formule (I), destiné, en particulier, à être utilisé dans les éléments commutateurs selon l'invention est également décrit.
