The method is for directing light in a fluorescent piece. Sequentially placed wedge-shaped pieces (40-48) form a multiple-piece arrangement (38). Each piece has a base surface (12) and a sloping top surface (14) so that there is a first pointed end (20) at one end and a short end surface (18) at a second opposite end thereof. The pieces (40-48) are exposed to light beams that hit fluorescent particles (24) disposed inside the pieces. As a result, the particles emit a fluorescent light that are reflected off the inner surfaces of each piece as long as the light beams do not hit the surface at a perpendicular angle. The light beams (52a-52e) are directed to penetrate the short end of each piece to form a continuous illuminated surface (53). |
