Light emitting diodes (LED) is the light source of the future because of energy efficiency, performance, and life-time. Due to their small dimension and high flux many innovative solutions for non-glare and controlled light distribution are developed for various applications. This chapter deals with a joint R&D project (R&D project, funded 2012–14 by AiF: Entwicklung flacher, durchsichtiger und gleichzeitig selbst-leuchtender Elemente nach dem Prinzip der Lichtleitung mit gezielter Lichtauskopplung durch Mikrostrukturen. Research team: Green Building R&D, JO GmbH & CO. KG., RIF Institut fur Forschung und Transfer, Temicon GmbH, TU Dortmund Faculty of Electro- and Information Technology) for edge lit and highly transparent light guiding plates with controlled single-sided light emission. The transparency allows for looking through the plate and is not affected by the specific micro-structure for light emission on one surface of the light guide. |
