Abstract:
Lightguides and methods for making and using the same are disclosed. A structured layer is provided with light extractors formed on a structured surface thereof. In some cases, the structured layer is removably laminated onto a substrate to provide uniform light extraction. In some cases, indicia are cut out of the structured layer and laminated onto the substrate. In some cases, the structured surface of the structured layer is selectively filled to form a pattern for light extraction. In some cases, a tool for producing a structured layer has a region of structures selectively filled to form a pattern for light extraction on the produced structured layer.
