Abstract

La présente invention concerne à titre principal une paroi qui laisse passer la lumière principalement dans un sens. Le principal objectif poursuivi par la présente invention est de piéger la lumière dans un volume, pour améliorer la luminosité dans un volume, ou pour produire la chaleur. Elle comporte un réseau lenticulaire (1), et une surface (2) située à proximité du domaine des centres focaux desdites lentilles élémentaires, dite surface de focalisation. Cette surface de focalisation (2) se transforme sous l'effet de la chaleur pour passer d'un état sensiblement opaque à une température dite « basse », à un état sensiblement transparent à une température dite « élevée ». Elle laisse donc pénétrer les rayons du soleil mais ne laisse qu'une très faible partie de la lumière passer dans l'autre sens.
