The invention relates to a sunlight-LED (light-emitting diode) mixing intelligent lighting system based on a light guide pipe and optical fiber in an underground station. Sunlight in fine days is directly introduced into the underground through the light guide pipe and the optical fiber to achieve lighting and ventilating of the underground station. In cloudy days or at night, the system can be automatically switched into LED electric compensation lighting, and intelligent lighting of the underground station is achieved. Compared with the prior art, the environment-friendly underground lighting can be achieved, underground lighting and ventilation cost is saved, and the tracking precision of the sun is improved.
