【摘要】：公路隧道过渡段照明亮度设置需要随洞外亮度的变化进行调整，太阳光光纤照明系统输出端亮度也是随着太阳光照度的变化而改变。根据此规律，可以将太阳光光纤照明系统应用在隧道过渡段照明中，减少隧道过渡段依靠电力照明而产生的巨额电费支出和能源消耗。但是目前太阳光光纤照明系统的耦合传输效率较低，无法满足隧道过渡段照明应用。因此本文主要对太阳光光纤照明耦合系统进行研究和分析，设计出满足隧道照明需求的太阳光光纤照明耦合系统。本文在研究太阳光特性和光纤照明理论的基础上，分析了公路隧道照明需求，计算出隧道洞内亮度与洞外亮度的关系，得出能够满足隧道照明需求的耦合系统耦合效率值。通过对不同聚光器的聚光能力对比分析，根据隧道照明特点选用菲涅尔透镜作为系统的聚光器。并在分析计算了菲涅尔透镜参数关系及聚焦特性的基础上，提出两级聚光耦合的设计思路，进而设计出菲涅尔透镜与非球面透镜组成的两级聚光系统，以提高耦合效率。利用zemax软件对耦合系统建立仿真模型，通过软件的优化功能，得出满足隧道光纤照明耦合系统要求的系统参数。结果表明：太阳光通过系统耦合后，耦合效率可以满足隧道照明需求。并且在不同太阳光入射角度条件下，光纤耦合过程中出现横向偏移误差、纵向偏移误差、角度偏移误差时，得出可以满足系统耦合效率的角度和误差偏移量区间。搭建了用于隧道照明的太阳光光纤照明实验平台，通过实际测试，结果表明光纤照明耦合系统耦合效率值与理论计算值相符，同时通过光纤传输50m、100m、150m、200m后的照度可以满足隧道洞内亮度要求，证明本文设计的光纤照明耦合系统可以满足隧道的照明需求，，为系统在隧道照明中的应用提供了参考。
[Abstract]:The luminance setting of the transition section of the highway tunnel needs to be adjusted with the change of the luminance outside the tunnel, and the brightness of the output end of the solar fiber illumination system also changes with the change of the solar illumination. The solar fiber optic lighting system can be applied to the tunnel transition section lighting, which can reduce the huge electric expenses and energy consumption caused by the electric lighting in the tunnel transition section, but the coupling transmission efficiency of the solar fiber optic lighting system is low at present. Therefore, this paper mainly studies and analyzes the coupling system of solar fiber lighting, and designs a coupling system of solar fiber lighting to meet the needs of tunnel lighting. Based on the study of the characteristics of solar light and the theory of optical fiber illumination, this paper analyzes the lighting requirements of highway tunnel, and calculates the relationship between the luminance inside the tunnel and the luminance outside the tunnel. The coupling efficiency of the coupling system can meet the needs of tunnel lighting. According to the characteristics of tunnel lighting, Fresnel lens is selected as the concentrator of the system. Based on the analysis and calculation of the Fresnel lens parameter relationship and focusing characteristics, the design idea of two-stage condenser coupling is put forward. Furthermore, a two-stage condensing system composed of Fresnel lens and aspheric lens is designed to improve the coupling efficiency. The simulation model of the coupling system is established by using zemax software. By optimizing the function of the software, the system parameters that meet the requirements of the coupling system of the tunnel optical fiber lighting are obtained. The results show that: after the solar light is coupled through the system, The coupling efficiency can satisfy the lighting requirement of tunnel, and under the condition of different incidence angles of solar light, there are transverse offset error, longitudinal offset error and angle deviation error in the process of optical fiber coupling. The angle and error offset range which can satisfy the coupling efficiency of the system are obtained. The experimental platform of solar fiber illumination for tunnel lighting is built, and the actual test results are given. The results show that the coupling efficiency of fiber-optic lighting coupling system is in good agreement with the theoretical calculation value, and the illuminance of the optical fiber transmission from 50mt to 100mt / 100mt / 200m can meet the requirement of luminance in the tunnel tunnel. It is proved that the fiber-optic lighting coupling system designed in this paper can meet the lighting requirements of the tunnel and provide a reference for the application of the system in the tunnel lighting.
