[0002] Currently, solar-powered light-guiding lighting systems are widely used in large-span public buildings and underground structures in developed countries. They are found in many public buildings, such as train stations, subway stations, airports, underground passages, sports stadiums, high-end hotels, large shopping malls, and large parking lots. It solves the problem of lighting difficulties in buildings and large underground facilities, replacing traditional indoor electric lighting with natural sunlight, thus completing the third lighting revolution after fire lighting and electric lighting. Compared with traditional lighting methods, existing light-guiding lighting systems have unique advantages, good development prospects, and broad application areas, making them a truly energy-saving, environmentally friendly, and green lighting method.

[0039] Working principle: The composite light source emits light that shines on the surface of the first right-angle prism. After reflection, the light shines on the second right-angle prism, which reflects the light into the light guide tube. The light is reflected by the light reflector, then reflected by the reflective film, and then emitted from the light guide tube. After being focused by the spotlight cover, the light shines on the illumination area.
