Abstract: The method is for directing light in a fluorescent piece. Sequentially placed wedge-shaped pieces form a multiple-piece arrangement. Each piece has a base surface and a sloping top surface so that there is a first pointed end at one end and a short end surface at a second opposite end thereof. The pieces are exposed to light beams that hit fluorescent particles 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 are directed to penetrate the short end of each piece to form a continuous illuminated surface.

Abstract: The invention relates to a light guide panel capable of distributing light beams incident from a light source to an entire surface thereof. The light guide panel has at least two through holes formed in a path of the incident light beams, apart in a predetermined interval from a light incident surface. The through holes are formed perpendicular to the path of the incident light beams, and lined along the light incident surface of the light guide panel. The light guide panel according to the present invention can improve uniformity of incident light without increasing the number or size of the light source, thereby distributing the incident light in a wider angle and decreasing a light mixing region. The light guide panel is produced in a simple manufacturing process, reducing the manufacturing costs.

Abstract: An optical system utilizing a light pipe in which light travels by total internal reflection (TIR) accurately controls the light exiting the pipe. The system achieves accurate control of the reflected light by selectively extracting light from a limited area of the light pipe. The configuration of the reflectors used for the selective extraction of the light determines the nature of the output light. The reflectors are preferably located on an output side of the light pipe. All light output by the system is directed by the reflectors.
