A daylight transmission system for a building comprises a biaxial posture control mechanism (1), a controller (9), a light position sensor (12) and an optical component, wherein, the optical component includes a movable optical component and a fixed optical component. The movable optical component includes an optical lightening device (2); the fixed optical component includes a first stage receiver (15) and follow-up receivers (17, 18, 19). The system can economically and precisely transmit the incidence light polymerized in a form of approximate parallel light to the inside of the building without depending on the medium, such as an optical fiber. The direct sunlight slanting on the surface of the building is converted into a light transmitting along a fixed direction and then is guided into the inside of the building through a multistage reflection mechanism by the system with the aid of tracking the sun. The system can be directly mounted on the fa?ade of any building, has a wide range of applications and is economical and simple, and greatly reduces the manufacturing and application cost of the daylight transmission system. |
