Abstract
A billboard illuminated by optical fibers is realized by including a framework (1) having plurality outer surfaces (11) for display purpose, multiples optical fibers (2) provided within the framework (1) for guiding light from one surface (11A) to another (11B), and said optical fibers (2) are arranged in a matrix fashion with each optical fiber is spaced by a predetermined space (h) to form a figure or characters, a projecting device (3) placed away from the framework (1) by a predetermined distance (W) as light source, and a cladding (4) applied onto outer surfaces (11) for reinforcing the junction portion where the optical fiber (2) exposed from the outer surfaces (11).
Claims10
An optical fiber billboard consists essentially of
- A framework (1);
- having a plurality of outer surfaces (11);
- A plurality of optical fibers (2) provided within said framework (1);
- each optical fiber (2) includes a first end (21), a second end (22) and a light guiding body (23) between said ends;
- said optical fibers (2) are incorporated in said framework (1) for guiding light from a side of the framework (1) to an another side hereof;
- said first and second ends (21, 22) are exposed and visible from said outer surfaces (11) and are arranged in a matrix fashion spaced by a predetermined distance (h) between each other to form figures or characters;
- A projecting device (3) is provided at a side of the framework (1) with a projecting distance (W) away from said framework (1), projecting a light to the surface (11) where first ends (21) of said optical fibers (2) are provided;
- and
- A transparent cladding (4) is applied on each outer surface (11) for covering said first end (21) and second end (22) of each optical fiber (2), and for securing the optical fiber (2) onto the framework (1).
