Title:
LIGHT SIGNAL SENSOR
Document Type and Number:
WIPO Patent Application WO/2011/085557
Kind Code:
A1
Abstract:
A light signal sensor is provided. The sensor includes: a first solar cell (E1), a second solar cell (E2) and a sampling circuit (1); the positive electrode of the first solar cell is electrically connected with the negative electrode of the second solar cell and the negative electrode of the first solar cell is electrically connected with the positive electrode of the second solar cell; the sampling circuit is connected across the positive electrode and the negative electrode of the first solar cell or the second solar cell; when the intensity of illumination on the first solar cell is higher than the intensity of illumination on the second solar cell, the voltage produced by the first solar cell is higher than the voltage produced by the second solar cell; when the intensity of illumination on the second solar cell is higher than the intensity of illumination on the first solar cell, the voltage produced by the second solar cell is larger than the voltage produced by the first solar cell. The sensor can effectively capture the light signal and transfer the signal to subsequent tracking device to ensure adjusting the position of tracker correctly.
