Title (EN) OPTICAL STRUCTURES FOR REDIRECTING DAYLIGHT
(FR) STRUCTURES OPTIQUES POUR REDIRIGER LA LUMIÈRE DU JOUR
Abstract: front page image
(EN)Window glass having sun-facing daylight redirecting optical structures with an embedded surface diffuser patterned on them. The optical structures are generally linear and formed from a repeating unit cell. Each unit cell has a base, two or more peaks opposite the base, and at least one curved side between the base and the peaks. The other sides between the base and the peaks can be substantially straight, curved, or a series of facets approximating a curve.
(FR)La présente invention concerne un verre à vitres comportant des structures optiques redirigeant la lumière du jour face au soleil avec un diffuseur de surface incorporé modelé sur celles-ci. Les structures optiques sont généralement linéaires et formées d'une cellule unitaire répétitive. Chaque cellule unitaire comporte une base, deux pics ou plus opposés à la base, et au moins un côté courbé entre la base et les pics. Les autres côtés entre la base et les pics peuvent être sensiblement rectilignes, courbés, ou une série de facettes constituant une approximation de courbe.
