Concrete wall with optical fibers display device

Abstract

A concrete wall with optical fibers display device comprises a concrete wall having plurality outer surfaces for display purpose, multiples optical fibers are embedded within the concrete wall for guiding light from one surface to another, and said optical fibers are arranged in a matrix fashion with each optical fibers is spaced by a predetermined space to form a figure or characters, a projecting device placed away from the concrete wall by a predetermined distance as light source, and a layer is painted onto the whole outer surfaces of the concrete wall for reinforcing the junction portion where the tip of optical fibers with the surfaces of the concrete wall.

1 . A concrete wall with optical fibers display device which is comprised of:
 A concrete wall ( 1 );   Multiple optical fibers ( 2 ), and   A projecting device ( 3 );   Said concrete wall ( 1 ) comprises several outer surfaces ( 11 ) and said optical fibers ( 2 ) are embedded within said concrete wall ( 1 ); each optical fibers ( 2 ) includes a first end ( 21 ), a second end ( 22 ) and a light guiding body ( 23 ) between said ends; the optical fibers ( 2 ) are applied for guiding light from a side of said concrete wall ( 1 ) to another side hereof; said first and second ends ( 21 ,  22 ) of the optical fibers ( 2 ) are visible from said surfaces ( 11 ) and are arranged in a matrix fashion, spaced with a predetermined distance (h) between each other to form figures or characters; the projecting device ( 3 ) is provided at a side of the concrete wall ( 1 ) with a projecting distance (W) away from said concrete wall ( 1 ), projecting a light to the surface ( 11 ) where first ends ( 21 ) of said optical fibers ( 2 ) are provided.   
     
     
         2 . A concrete wall with optical fibers display device defined in  claim 1 , wherein each surface ( 11 ) of said concrete wall ( 1 ) is painted with a light-preamble titanium compound layer ( 4 ). 
     
     
         3 . A concrete wall with optical fibers display device defined in  claim 1 , wherein said projecting device ( 3 ) is selected from one of following: a multi-color spot light, a mono-color spot light, a projector, a LED or LCD illuminating device or ambient light. 
     
     
         4 . A concrete wall with optical fibers display device defined in  claim 1 , wherein said two surfaces ( 11 ) where the first and second end of an optical fibers ( 2 ) are exposed are facing each other or adjacent.
