Paper Abstract

Directly using sunlight for the illumination of rooms that have no windows is a very important measure for higher energy efficiency and CO2 reduction in the next future, especially for countries along the sunny belt. The Sollektor ®, developed at the Polymer Optical Fiber Application Center in Nuernberg, Germany, offers an efficient way to do that. The Sollektor is a combination of a plastic injection moulded concentrator optics array, a control unit which tracks the sun over the day and a polymer optical fiber bundle, guiding the collected light into the rooms. In order to ensure the illumination even at times without sun we present concepts and first results for the combination with conventional LED in order to obtain a 24 hillumination on a high efficiency level with high quality light.
