摘要

【目的】

有效收集太阳光并通过光纤传输将其导入需要照明的区域，可以取代部分传统光源。光纤采光系统受入射光角度和入射耦合效率的影响十分明显，为了提高光纤采光系统的光能利用率，需要从太阳光方位自对准和提高空间光到光纤的耦合效率两个方面进行优化改进。

【方法】

针对实时对准太阳光的问题，文章设计了针对天顶角非线性响应的光纤探头结构用于跟踪太阳光的入射方向，并通过自适应机械结构控制采光结构的位姿。由于采用了多光纤探头，对应测试角度是预先固定的，解决了太阳光强随天顶角变化不均的问题。同时，多光纤探头组合可以大幅提升检测视场，保证了全时段测试精度的一致性。针对空间光到光纤耦合效率的问题，文章设计了双透镜结构与光纤球面端面封装，用于提高光纤有效数值孔径，大幅提升了入射光的角度范围。

【结果】

文章仿真分析了半径调制比与光纤球面半径对耦合效率的影响。仿真结果显示，当半径调制值为0.61，光纤球面半径为228.75 μm时，耦合效率达到最大值。实验分别针对耦合效率与光照度进行了测试分析，结果显示，当透镜2的焦距

为8.0 mm时，光功率达到最大值352.14 mW。球面端面结构在8°以内的光功率衰减小于5%，明显优于传统平面端面型。晴天时，球面端面光纤采光平均光照度为10 392 lx，全时段光能转化率为38.82%，而平面端面型仅为23.69%。

【结论】

文章所提系统在太阳光方位探测和空间光耦合至光纤这两个主要环节上进行了改进与优化，仿真分析与实验结果验证了系统设计的可行性。从光照稳定性与光能转化率上看，文章所提设计可以在不改变外径尺寸的前提下进一步提高系统光能利用率。

Abstract

【Objective】

Effectively collecting sunlight and transmitting it through optical fibers to illuminate areas that require lighting can replace some traditional light sources. The fiber optic day lighting system is significantly affected by the angle of incident light and the coupling efficiency of incident light. In order to improve the light energy utilization of the fiber optic day lighting system

it is necessary to optimize and improve it from two aspects: self-alignment of sunlight direction and improving the coupling efficiency of spatial light to the fiber optic.

【Methods】

A fiber optic probe structure is designed to address the issue of real-time alignment of sunlight

targeting the nonlinear response of zenith angle. It is used to track the direction of sunlight incidence and control the orientation of the lighting structure through an adaptive mechanical structure. Due to the use of multiple fiber optic probes

the corresponding testing angle is pre-fixed

solving the problem of uneven variation of solar intensity with zenith angle. Meanwhile

the combination of multiple fiber optic probes can significantly improve the detection field of view

ensuring consistency in testing accuracy throughout the entire time period. Addressing the issue of coupling efficiency from space light to optical fibers

a dual-lens structure and fiber-optic spherical end-face encapsulation have been designed to enhance the effective numerical aperture of the optical fiber

significantly expanding the angular range of incident light.

【Results】

The influence of radius modulation ratio and fiber spherical radius on coupling efficiency is simulated and analyzed. The simulation results show that when the radius modulation value is 0.61 and the fiber spherical radius is 228.75 μm

the coupling efficiency reaches its maximum value. The experiments are conducted to test and analyze the coupling efficiency and illuminance. The experimental results show that when the focal length f of the second lens is 8.0 mm

the maximum optical power reaches 352.14 mW. The optical power attenuation of the spherical end face structure within 8° is less than 5%

which is significantly better than the traditional planar end face structure. On sunny days

the average illumination of the spherical end face fiber is 10 392 lx

and the light energy conversion rate during the entire period is 38.82%. The planar end face type is only 23.69%.

【Conclusion】

This system is improved and optimized in the two main aspects of solar azimuth detection and spatial optical coupling to optical fibers. Simulation analysis and experimental results have verified the feasibility of the system design. From the perspective of light stability and light energy conversion rate

this design can further improve the system's light energy utilization efficiency without changing the outer diameter size.
