Abstract

L'invention concerne une fenêtre à intensité lumineuse réglable, équipée d'un matériau en feuille à intensité lumineuse réglable, ayant une caractéristique anti-éblouissement améliorée et une résistance à une force externe améliorée. Dans la fenêtre (10) à intensité lumineuse réglable selon la présente invention, le matériau en feuille (14) à intensité lumineuse réglable est enserré dans une couche creuse (24) dans un verre (12) à couches multiples comprenant une feuille de verre (16) côté extérieur et une feuille de verre (18) côté intérieur. Une feuille parmi la feuille de verre (16) côté extérieur ou la feuille de verre (18) côté intérieur présente une transmittance de la lumière visible de 70 % ou moins. Si ladite feuille de verre est la feuille de verre (16) côté extérieur, la quantité de transmission de lumière externe atteignant le matériau en feuille (14) à intensité lumineuse réglable peut être réduite, de sorte que l'éblouissement se produisant lorsque la lumière externe est diffusée par le matériau en feuille (14) à intensité lumineuse réglable puisse être réduit. De manière alternative, si ladite feuille de verre est la feuille de verre (18) côté intérieur, l'éblouissement se produisant lorsque la lumière externe est diffusée par le matériau en feuille (14) à intensité lumineuse réglable peut être réduit par la feuille de verre (18) côté intérieur. En outre, le matériau en feuille (14) à intensité lumineuse réglable est protégé par le verre (12) à couches multiples, de sorte que la résistance à une force externe soit améliorée.
