Light Transmitting Concrete


Now wouldn’t this be a good idea for some of Lebel’s windowless rooms? This light transmitting concrete was developed in 2004 and is called LitraCon. I’m not having a very easy time thinking of many applications for this recent invention, but I’m sure it could save on lighting costs for rooms in which activities would be carried out during the day.

Litracon is a combination of optical fibers and fine concrete. The glass fibers lead light by points between the two sides of the blocks. Because of their parallel position, the light-information on the brighter side of such a wall appears unchanged on the darker side. The most interesting form of this phenomenon is probably the sharp display of shadows on the opposing side of the wall. Moreover, the colour of the light also remains the same.”
