PURPOSE: A sun tracker is provided to prevent accumulated errors by resetting the rotary angle of a panning device based on detection signals. CONSTITUTION: A sun tracker comprises an information obtaining unit, a tilting device(140), a panning device(130), and a main control unit. The tilting device tilts a lighting plate. The panning device supports the tilting device, and is pivotally installed on a base to operate the lightening plate. The main control unit controls the operation of the tilting device and panning device based on information on the sun position. The tilting device comprise a pair of rotary units, a tilting driving motor(142), and a power transfer unit(143). The pair of rotary units is pivotally installed on the outside of the panning device, and supports the lightening plate. The tilting driving motor is installed in the panning device, and operated in forward and reverse directions. The power transfer unit transfers the driving power of the tilting driving motor to the pair of the rotary units. |
