Disclosed is a method for integrating at least one optical element inside an insulated glazing unit comprising at least two glass panes, where the optical element has a plurality of perforations and a non-perforated area, where the non-perforated area prevents penetration of light in a building where the insulated glazing unit is mounted, and where the perforations have a depth/width ratio that allows for passage of light with given angles of incidence, while light having other angles of incidence are unable to pass though the perforations, which provides a shading effect, and wherein the optical element is arranged between the two glass panes by means of an adhesive, and where the adhesive is substantially not present in the perforations of the optical element.

L'invention concerne un procédé destiné à intégrer au moins un élément optique à l'intérieur d'une unité de vitrage isolé comprenant au moins deux panneaux de verre, l'élément optique comportant une pluralité de perforations et une zone non perforée, ladite zone non perforée empêchant la pénétration de lumière dans un bâtiment où est montée l'unité de vitrage isolé, et les perforations présentant un rapport profondeur / largeur qui permet le passage de lumière sous des angles d'incidence donnés, tandis que la lumière arrivant sous d'autres angles d'incidence est dans l'impossibilité de passer à travers les perforations, ce qui assure un effet d'ombrage, l'élément optique étant mis en place entre les deux panneaux de verre au moyen d'un adhésif, et l'adhésif étant sensiblement absent des perforations de l'élément optique.
