Sun tracking binding double-tube lighting detection means arranged photosensor rice fonts

The present invention discloses a sun tracking apparatus for detecting double-tube shaped light meter binding photosensor arrangement. Pipe means comprises opaque vertical mounting surface and a mounting surface disposed perpendicularly arranged two opaque tube, pipe and tube with a two-phase stick; pipe mounted in the bottom of a plurality of sub-type meter arrangement photosensor; bottom of the inner tube is attached to a dicarboxylic photosensitive sensor; an inner diameter larger than the inner diameter of a pipe two pipe; pipe length greater than the maximum height of a plurality of light-sensitive sensors along the mounting surface of the sub-type meter arrangement, tube a height of the pipe greater than two and less than or equal to 10 times the height of the inner diameter of tube II. Device uses fonts thickness meter tube and photosensor arrangement combined thick tube may be utilized not only large inner diameter and a low expansion characteristics height monitoring range, and with a plurality of photosensors disposed rice fonts simultaneously measure the light in multiple directions, thus the present apparatus has a wide detection range and high detection accuracy.
