SUNLIGHT TRACKING DEVICE |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a differential type sunlight tracking device for highly precisely detecting the incident direction of a sunlight with a low power. <P>SOLUTION: This sunlight tracking device includes a cylindrical section 20 having predetermined length and predetermined aperture; a driving part for rotating and moving the cylindrical section; a first detection part having a first pair of solar batteries 10a and 10b formed outside the cylindrical section for outputting a first differential voltage corresponding to the received light quantity difference of the first pair of solar batteries; a second detection part having a second pair of solar batteries 10c and 10d formed inside the cylindrical section for receiving sunlight made incident to the cylindrical section for outputting a second differential voltage corresponding to the received light quantity difference of a second pair of solar batteries; and a driving control part for driving the driving part based on the first differential voltage and the second differential voltage. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
