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 für 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. The work plan, including optimization of microstructures by ray-tracing simulation, development of manufacturing technology for large scale production, and system design for different applications, is carried out by an integrated team from university and industry. The main objectives are economic manufacturing technologies, high quality and low energy lighting and architectural system integration.
