| Abstract: | A cylindrical prism light guide made of PMMA is introduced in this paper and its performance is analyzed. Experiments show that the guide has high light-transmitting efficiency that makes high illuminance at the end of the guide so that the surface of the guide is illuminated uniformly. The cylindrical PMMA prism light guide has many advantages such as low cost and easy manufacturing technique and can be used in lighting or daylighting of underground buildings and windowless buildings, or buildings in which inflammable and explosive products are manufactured. It can also be used in nightscape lighting as a decorative lighting fixture. |
