Patent number: 9978892Abstract: A method of manufacturing a transparent pane, in particular a glass pane, which includes on at least one of its main surfaces a surface structure including an assembly of specified individual motifs in relief, in particular pyramids, cones, or truncated cones, created by embossing or by rolling. A structure is created on the surface of the pane constituted by individual motifs, based on one or more basic motifs but which are distinguished from each other by their depth, their height, and/or the perimeter of their base area, and/or by the position of their peak with respect to their base. With this variation, formation of intensity peaks of the reflected light is prevented and at the same time a high quality of light trapping is obtained by panes suitable, for example, for solar applications.Type: GrantFiled: February 8, 2017Date of Patent: May 22, 2018Assignee: SAINT-GOBAIN GLASS FRANCEInventors: Nils-Peter Harder, Ulf Blieske, Dirk Neumann, Marcus Neander, Michele Schiavoni, Patrick Gayout
