Abstract
In this paper, fiber optic lighting technology and intelligent shading technology combined to improve. A number of miniaturized natural light acquisition units are arranged alternately on the outer sun visor and a light tracking control sensor is set in the center position of each group of outer sun visor. Through intelligent light tracking control, the external sunshade system rotates with the incident light Angle and maintains a vertical relationship with the incident light. The natural light acquisition unit attached to the outer sun visor is also kept vertically incident with the incident light. The system transmits the collected and focused light by quartz fiber to indoor natural light and LED mixed light lighting lamps for lighting. The feasibility of this new green lighting system is proved by experiments under actual weather conditions, and it has good performance. In the experiment, the maximum illumination inside the closed darkroom is more than 10 times when the lighting system is installed.
