[Abstract]:Sun-guided lighting is one of the most important applications in the field of solar energy utilization. In view of the dark room in the building, the method of introducing the solar light into the interior of the building by optical fiber can not only effectively utilize the light energy and save the electric energy, but also make people enjoy the sunlight and the body and mind in the interior to a certain extent. Improving the quality of life, the technology has a wide range of application prospects. The thesis focuses on the system design and performance optimization of the fiber-optic sunlight guide lighting system. The experimental research is carried out. The main work is as follows: 1. Based on the analysis of the movement of the sun in relation to the earth, the general scheme of the distributed fiber-optic sunlight guiding illumination system without tracking and collecting light is put forward, the orientation and layout of the distributed collector are determined, and the proper defocus is adopted. Array combination mode in the receiving plane of the layout of optical fiber, to ensure the system multi-channel full-time lighting requirements; 2. The optical design and performance evaluation of the light guide lighting system are completed. It includes the parameter design of Fresnel lens, the key element of collecting light, and the analysis of its influence on the effect of concentrating light, the light energy transfer and illuminance analysis in the system, etc. 3. The light energy transfer and illuminance of the system are analyzed by LightTools optical software simulation method. 4. The module of light guide lighting system is built, and the corresponding experimental research is carried out. Including: convergent spot trajectory measurement; real-time sunlight illumination measurement and so on.
