为了利用绿色能源有效解决公路隧道进出口区段的“黑洞效应”和“白洞效应”, 在阳光输送机研究的基础上, 研制一种利用平行太阳光直接实现公路隧道进出口区段增强照明功能的新系统。该系统通过光路变换和反射等措施实现了在无光纤等传输介质条件下高效率、远距离的太阳光输送功能, 利用太阳光本身时有时无的性能缺陷改善了隧道增强照明系统亮度自适应隧道外光强的技术要求, 针对受光体位置固定不变的系统专门设计了极轴式自动跟踪系统, 保证了对太阳光的实时跟踪。实验结果证明, 该增强照明系统不但无须光导纤维或者导光管, 而且使得传输效率提高40%左右, 为隧道等白天也需要增强照明的地下工程直接利用太阳能开辟了一条新路。

In order to eliminate the “black-hole effect” and “white-hole effect” efficiently by taking use of green energy, based on the research of sunlight conveyor, a new system for enhanced illumination is developed by using enhanced parallel sunlight on the import and export zone of the highway tunnel. High efficient and long distant sunlight transporting is achieved under the condition of no-optical-fiber-like medium through optical path transformation and reflection. The technical requirement of self-adaptation with the natural sunlight in tunnel enhanced illumination is solved automatically by taking the disadvantage of sunlight intensity changing. According to the fixed photo-receptor system, a polar axis type automatic tracking system is designed, which realizes the real-time tracking for the sunlight. The experiment result shows that the system not only improves the transmission efficiency by about 40% without using optical fiber or light pipe, but also develops a new way for the popularization and application of direct sunlight lighting in the tunnel and other underground engineering in the future.
