Abstract: Taking the optical fiber lighting system of automatic solar tracking which guides light into indoor rooms as the research objective, the hardware composition, software flowchart and light-guiding of the system are well designed. The tracking capability and light guiding performance have been verified by a 15-meter-long optical cable light-guiding experiment and related simulations. The experimental results show that the optical fiber lighting system of automatic solar tracking has high accuracy, good stability, high coupling efficiency. Under the general solar lighting condition, the optical fiber interior lighting system designed in this paper can provide healthy, efficient interior illumination in libraries, basements, and other sunless rooms.
