Litracon as tough as concrete, yet light can get through it. Litracon is a combination of optical fibers and concrete. A wall made of Litracon has the strength of traditional concrete but thanks to an embedded array of optical glass fibers, which lets in the view of the outside world, such as the silhouette of trees, or passersby, that are displayed inside the building.
The glass fibers allow light to travel by points between the two sides of the blocks. Due to their parallel placement, the light-information on the brighter side of such a wall seems unchanged on the darker side. Also there is no change in the color of the light.
An array of thousands of optical glass fibers runs parallel to each other between the two main surfaces of each block. Theoretically, there is almost no loss in light up to 20 meters due to the fibers in such a block and hence a wall structure built from light-transmitting concrete can be several meters thick.
In 2001 Hungarian architect Aron Losonczi invented Litracon, the first light transmitting concrete and in spring 2004 he founded his own company, Litracon Bt., located in the Hungarian town Csongrád.
