摘　　要：天然导光技术的应用对于改善地下空间、大进深空间的采光质量具有重要作用。传统的导光管计算方法多基于某一或某几种特定的导光管的实验数据推算得来,不具有普遍适用性。本文基于日光系数法,对光线在圆柱形导光筒中的传输特性进行了分析,建立了导光筒光传输特性数学模型,并利用TracePro软件对该数学模型的准确性进行了验证。Application of natural tubular daylight technology is important to improvement of daylight quality in underground space and deep space.The traditional light pipe calculation method is generally based on calculation of the experimental data from certain or some specific light pipes,which lacks general applicability.Based on daylight coefficient computational method,this paper analyzes the light transfer characteristics in tubular daylight device,establishes a mathematical model regarding light transfer characteristics of light in tubular daylight device and utilizes TracePro software to verify the accuracy of the mathematical model.
