| Popis: | 102 Because of the energy crisis, renewable energy utilization becomes popular issue in countries around the world. There are many renewable energies such as solar, wind, hydro, geothermal, tidal and biomass energies ... etc. Among these renewable energies, solar energy is a potential one for wide applications. It’s an abundant and clean energy. If we can utilize solar energy as much as we can. It can reduce the seriousness of energy crisis. This study is committed to develop Natural Light Illumination System (NLIS) for providing comfortable and healthy indoor illumination, which is a solar energy utilization system. Despite of the solar cell which utilizes solar energy with opto-to-electricity conversion, the NLIS guides light into indoors without energy conversion. It reduces the loss of energy conversion. The NLIS can be divided into three subsystems which are light collecting, light transmitting and light emitting subsystems.In the conventional NLIS, it uses optical fibers to couple light collecting subsystem and light transmitting subsystem. This paper presents a coupler design for the NLIS. The coupler is a modular design; the coupler can be cascaded for stacked LightBrick modules. For a 5 x 5 stacked LightBrick module, using the coupler can reduce 80% fiber consumption and promote the performance of the NLIS. Reduceing the fiber consumption can reduce the engineering complexity and the fiber cost. |
