Abstract
In underground parking lots and the like, lighting devices are required during the day because there is no medium such as windows that allow sunlight to enter. In addition, in many buildings, due to lack of lighting, lighting is also required during the day, which causes a great waste of energy. In view of the above situation, an indoor lighting facility based on fiber-optic natural light-based power supply is designed. This design is mainly divided into three parts: mechanical concentrating platform, optical fiber transmission part and light diffuse reflector. By arranging a mechanical concentrating platform that can receive sunlight and install solar panels and concave mirrors in a place where the light source is received, the received natural light is transmitted to the room through the optical fiber with extremely high transmittance, and passes through the room. The astigmatism device distributes the natural light transmitted into every corner of the room as much as possible. This design can greatly save the use of electrical energy.
