在現今許多綠建築的應用中,以節省能源損耗,將自然光導引至室內做照明使用,即為自然光照明系統。其中集光器的效率最為重要,許多研究提出集光器設計都有集光面積與集光效率不足的問題。因此,本文提出一個新式靜態雙層可堆疊集光器,單一模組包含數個導光磚條作為集光結構與導光三角柱作為導光結構。對稱的設計將光線導引至兩個相反方向的出口端以利後方系統作照明使用。以單一模組為基礎,雙層的結構,設計將上下兩層集光結構交錯避開,自然光可以高比率的被導光磚收集。在單一模組集光面積之下,光線由上層與下層共四個出口導出。在垂直入射的平行光源設定,單一模組集光面積下效率可達29.6%。在夏季正中午時更可提供658.26流明的能量。採用雙層可堆疊的模組化方式,可無限延伸,適用於各式建築。
Renewable energy has become a focal point in view of the current energy crisis. One form, solar energy, is a promising solution to reduce overall energy consumption. Much research has been conducted into the uses of solar energy, including the guiding of natural light into a room for illumination. While existing systems are functional, adoption has lagged due to the low efficiency of existing collectors. To solve this problem, we present a novel design that leverages static, doubly-layered solar collectors. An integrated module will contain multiple, prismatic elements to collect natural light, plus a guide plate to conduct the light to its intended egress. Further, a dramatic increase in the collection area is obtained by shifting a doubly-layered, modular design by one half of its canonical width. The result of this research is a prismatic light collection design that provides four outputs per unit with a per-output efficiency exceeding 6%. This four-output module provides a total of 658 lumens from normal, incident sunlight.
