Patent ID: 8297794

Claim:
A method for modifying a directing light in a fluorescent piece, comprising: providing sequentially placed wedge-shaped pieces so that a first piece is adjacent to a second piece that is adjacent to a third piece to form a multiple-piece arrangement, each piece having a base surface and a sloping top surface, the base surface and the top surface having a first pointed end at one end and a short-end surface at a second opposite end thereof, the pieces having a plurality of fluorescent particles disposed therein, the base surface, the top surface and the short-end surface of each piece being constructed of a material that only permits light beams from inside to pass therethrough when the light beams are transmitted at a perpendicular angle relative to the base surface, the top surface or the end surface; exposing the top surfaces of the pieces to light beams from above the arrangement; the light beams penetrating the top surfaces and hitting the fluorescent particles; in response to the light beams, the fluorescent particles emitting monochrome light beams; the monochrome light beams hitting an inside surface of the top surface at an angle other than a perpendicular angle; the monochrome light be reflecting off the inside surface of the top surface as reflecting monochrome light beams; the reflecting monochrome light beams being directed towards the short-end surface and hitting the inside surface of the short-end surface at the perpendicular angle and penetrating through the short-end surface as emitting monochrome light beams so that a combination of the emitting monochrome light beams forms a continuous illuminated surface in one direction only through the short-end surface.
