A light collection system. The light collection system comprises a first light collector (11), a second light collector (12) and an optical fiber (13), sequentially arranged on a light path. The second light collector (12) comprises an incident light port (121) and an emergent light port (122), the emergent light port (122) being coupled to the optical fiber (13). The first light collector (11) is configured to gather sunlight to the incident light port (121) of the second light collector (12), and the second light collector (12) is configured to collect the incident sunlight into the optical fiber (13) for transmission. Edges of the incident light port (121) comprise a long edge and a short edge. A gathered light spot formed on the incident light port (121) of the second light collector (12) by the sunlight moves on the incident light port (121), and a component of the movement speed of the gathered light spot at every moment on the long edge is greater than a component on the short edge. The light collection system can prolong time when sunlight can be output when the light collection system is under a stationary condition, and the luminous flux collected by the light collection system is increased. |
