Abstract
Green energy issues have been concerned by people in recent years; Lots of researches focus on natural light guiding system, health lighting system, especially on solar energy applications. Natural light guiding system is divided into three parts which are part of collection, part of transmission and part of lighting. In the future, natural light guiding systems can be expected to be used in large areas. Therefore, how to collect the convergence of systems efficiently of natural light is an important topic. In the traditional structure, the connection of natural light guiding system and transmission fiber coupler efficiency is less than 50%. We have put forward a Y branch structure to be used for increasing the efficiency of convergence, we have proposed Y-branch structure of the components, Polymethylmethacrylate (PMMA), is mainly to be used to connect the natural light guiding systems and plastic optical fiber which can be transmitted efficiently up to more than 80%.This article provides a low-cost and the best efficient transmission; this Y branch structure can be regarded as a new kind of convergence device.
