Title (EN) LIGHT REDIRECTING CONSTRUCTIONS AND METHODS FOR SEALING EDGES THEREOF
(FR) STRUCTURES DE REDIRECTION DE LUMIÈRE ET PROCÉDÉS POUR SCELLER LES BORDS DE CELLES-CI
Abstract:
(EN) The present disclosure relates to articles and methods of sealing light redirecting film constructions comprising a microstructured optical film, such as a daylight redirecting film, bonded to another film. This type of assembly may serve various purposes. For example, the assembly may protect the structured film, provide additional functionality, such as diffusion or infrared reflection, and/or facilitate attachment of the microstructured optical film to a mounting surface, such as a glazing or window pane. The methods for sealing the edge of a light redirecting construction inhibit ingress of water and other contaminants during the film installation and afterwards during its regular use.
(FR) La présente invention concerne des articles et des procédés de scellement de structures de film de redirection de lumière comprenant un film optique microstructuré, tel qu'un film de redirection de la lumière du jour, soudé à un autre film. Ce type d'assemblage peut servir à divers usages. Par exemple, ledit assemblage peut protéger le film structuré, offrir une fonctionnalité supplémentaire, telle que la diffusion ou la réflexion infrarouge, et/ou faciliter la fixation du film optique microstructuré sur une surface de montage, telle qu'un vitrage ou un carreau de fenêtre. Les procédés de scellement du bord d'une structure de redirection de la lumière inhibent l'entrée d'eau et d'autres contaminants pendant l'installation du film et ensuite pendant son utilisation régulière.
