摘　　要：目前国内铁路客站大空间照明基本采用人工照明或与天窗采光相结合的照明方式。人工照明产生电力消耗;天窗采光产生局部聚光,亦会引起空调能耗的增加。寻求利用新的自然光采光技术显得十分必要。首先简要介绍了铁路客站大空间照明的现状及存在问题和导光管采光系统的原理及组成;重点围绕甘肃天水站大空间照明中导光管采光系统的应用,通过技术经济等多方面进行比较。研究分析表明:利用导光管采光技术可有效减少白天的电力消耗;比天窗采光光线更柔和、照度更均匀、隔热保温性更好,并将乘客与室外环境紧密地联系起来;投资回收期约为使用周期的1/3~1/2;可在铁路客站工程建设中合理地推广应用。At present, artificial lighting and skylight lighting are basically used in large space lighting of railway passenger stations in China. Artificial lighting produces power consumption;skylight lighting produces local focus, but also causes the increase of air conditioning energy consumption. It is necessary to seek new natural lighting technology.The paper briefly introduces the present situation and existing problems of large space lighting in railway passenger station, and illustrates the principle and composition of tubular daylighting system. It focuses on the application of tubular daylighting system in large space lighting of Tianshui station in Gansu Province, and compares the benefits in many aspects including technology and economy perspectives.The research and analysis show that: using tubular daylighting technology is more energy-saving, which can effectively reduce daytime power consumption. The light from tubular lighting is softer than from skylight lighting, and is more uniform illumination, better thermal insulation and insulation, and it closely links passengers with the outdoor environment;the payback period of investment is about 1/3~1/2 of the life cycle;it can be reasonably popularized and applied in the construction of railway passenger stations.
