Abstract
The present invention provide a sunlight collection device, it comprises a concentrator array composed by a plurality of concentrators and a light sensor electrically connected to the controller, the concentrator comprises a collecting cup and a collecting lens fixed to the collecting cup, a optical fiber runs through and is fixed at the bottom of the collecting cup, a plurality of light detection units which are electrically connected to the controller are provided around the optical fiber at the bottom of the collecting cup. The sunlight collection device and the method for tracking sunlight can not only locate the sunlight at second level, making the position quicker and more precise, but also making the light sensor and the collector of the sunlight collection device calibrate itself when mechanical deviation occurs, avoiding the phenomenon that although the sensor array precisely locating to sunlight and the light spot which is condensed by the collecting lens deviates the light-receiving of the optical fiber.
