Title:
SOLAR TRACKING SENSOR BASED ON FIBER LIGHT GUIDANCE
Document Type and Number:
WIPO Patent Application WO/2018/214513
Kind Code:
A1
Abstract:
A solar tracking sensor based on fiber light guidance. A lens (1) and four fibers respectively representing four directions are installed in a lens barrel (2) to serve as a fine-positioning daylighting module, and four groups of fibers are installed on the side of the lens barrel (2) to serve as a coarse-positioning daylighting module. A circuit board (7) and four photocells (61-64) are installed at the bottom of a cassette (5). Each of the photocells (61-64) is connected to fine positioning fibers (41-44) located in the same direction as the photocell, and is connected to coarse positioning fibers (45-48) located in a direction diagonal to the direction of the photocell. By using a daylighting method of combining fine-positioning daylighting and coarse-positioning daylighting, the number of the photocells (61-64) is reduced, and thus the design of the circuit board (7) is simplified, and costs are reduced; moreover, because the coarse-positioning daylighting module can collect sunlight in a wide-angle range, the tracking angle range of the sensor is enlarged.
