【摘要】：公路隧道過(guò)渡段照明亮度設(shè)置需要隨洞外亮度的變化進(jìn)行調(diào)整，太陽(yáng)光光纖照明系統(tǒng)輸出端亮度也是隨著太陽(yáng)光照度的變化而改變。根據(jù)此規(guī)律，可以將太陽(yáng)光光纖照明系統(tǒng)應(yīng)用在隧道過(guò)渡段照明中，減少隧道過(guò)渡段依靠電力照明而產(chǎn)生的巨額電費(fèi)支出和能源消耗。但是目前太陽(yáng)光光纖照明系統(tǒng)的耦合傳輸效率較低，無(wú)法滿足隧道過(guò)渡段照明應(yīng)用。因此本文主要對(duì)太陽(yáng)光光纖照明耦合系統(tǒng)進(jìn)行研究和分析，設(shè)計(jì)出滿足隧道照明需求的太陽(yáng)光光纖照明耦合系統(tǒng)。 本文在研究太陽(yáng)光特性和光纖照明理論的基礎(chǔ)上，分析了公路隧道照明需求，計(jì)算出隧道洞內(nèi)亮度與洞外亮度的關(guān)系，得出能夠滿足隧道照明需求的耦合系統(tǒng)耦合效率值。通過(guò)對(duì)不同聚光器的聚光能力對(duì)比分析，根據(jù)隧道照明特點(diǎn)選用菲涅爾透鏡作為系統(tǒng)的聚光器。并在分析計(jì)算了菲涅爾透鏡參數(shù)關(guān)系及聚焦特性的基礎(chǔ)上，提出兩級(jí)聚光耦合的設(shè)計(jì)思路，進(jìn)而設(shè)計(jì)出菲涅爾透鏡與非球面透鏡組成的兩級(jí)聚光系統(tǒng)，以提高耦合效率。 利用zemax軟件對(duì)耦合系統(tǒng)建立仿真模型，通過(guò)軟件的優(yōu)化功能，得出滿足隧道光纖照明耦合系統(tǒng)要求的系統(tǒng)參數(shù)。結(jié)果表明：太陽(yáng)光通過(guò)系統(tǒng)耦合后，耦合效率可以滿足隧道照明需求。并且在不同太陽(yáng)光入射角度條件下，光纖耦合過(guò)程中出現(xiàn)橫向偏移誤差、縱向偏移誤差、角度偏移誤差時(shí)，得出可以滿足系統(tǒng)耦合效率的角度和誤差偏移量區(qū)間。搭建了用于隧道照明的太陽(yáng)光光纖照明實(shí)驗(yàn)平臺(tái)，通過(guò)實(shí)際測(cè)試，結(jié)果表明光纖照明耦合系統(tǒng)耦合效率值與理論計(jì)算值相符，同時(shí)通過(guò)光纖傳輸50m、100m、150m、200m后的照度可以滿足隧道洞內(nèi)亮度要求，證明本文設(shè)計(jì)的光纖照明耦合系統(tǒng)可以滿足隧道的照明需求，，為系統(tǒng)在隧道照明中的應(yīng)用提供了參考。
[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.
