Title (EN) OPTICAL SWITCH ELEMENT COMPRISING A LIQUID-CRYSTALLINE MEDIUM
(FR) ELÉMENT DE COMMUTATEUR OPTIQUE COMPRENANT UN MILIEU LIQUIDE CRISTALLIN
Abstract: front page image
(EN)The present invention relates to an optical switch element, comprising a liquid-crystalline medium for the temperature-dependent regulation of radiant energy flow. The invention furthermore relates to the use of the optical 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 5-95% of a compound of the formula (I), in particular for use in the optical switch elements according to the invention.
(FR)La présente invention concerne un élément de commutateur optique comprenant un milieu liquide cristallin pour la thermorégulation du flux d'énergie rayonnante. L'invention concerne en outre l'utilisation de l'élément de commutateur optique pour la régulation du flux d'énergie rayonnante entre des espaces intérieurs et l'environnement et pour la régulation de la température des espaces intérieurs. L'invention concerne en outre un milieu liquide cristallin, caractérisé en ce qu'il comprend 5 à 95 % d'un composé de formule (I), en particulier pour une utilisation dans les éléments de commutateur optique selon l'invention.
