陽光為萬物生命所需的能量來源,若能將其引入室內以提供照明,有助於減輕對電力的需求,並對人類的生理和心理健康有益。自然光照明系統由三個子系統組成,包括集光、傳光和放光子系統。集光子系統將陽光集中和壓縮,再由傳光子系統傳至室內,最後由放光子系統提供穩定的照明。本論文旨在解決傳光子系統的準直光立方設計問題,透過擴束、縮束和光展量定理的概念優化準直器,以提升光線的準直度,實現遠距離的光線傳輸,並通過模擬分析,評估優化後準直器的準直效率。優化後的準直器在遠距離傳輸方面展現出良好的效能,能夠保留超過一半的能量,提供高能量輸出,同時維持較小的光斑尺寸和全發散角,這顯示出準直器的優異準直效率。
The sunlight serves as the essential energy source for all living beings. If it can be harnessed to provide indoor illumination, it would help alleviate the demand for electrical power and contribute to the physiological and psychological well-being of humans. The Natural Light Illumination System (NLIS) consists of three subsystems: the light collection, light transmission, and light emission subsystems. The light collection subsystem concentrates and compresses sunlight, which is then transmitted indoors through the light transmission subsystem. Finally, the light emission subsystem provides stable illumination.
This paper aims to address the design issues of the collimating LightCube in the light transmission subsystem. By optimizing the collimator's design using concepts such as beam expansion, beam compression, and Etendue, the goal is to enhance the collimation of light and achieve long-distance light transmission. The optimized collimator's collimation efficiency is evaluated through simulation analysis. The results demonstrate that the optimized collimator exhibits superior collimation efficiency compared to the non-optimized counterpart. Even with increasing transmission distances, the optimized collimator maintains higher total energy output, significantly smaller spot size, and reduced full divergence angle, indicating excellent collimation performance.
