SUN TRACKING APPARATUS AND SUNLIGHT IRRADIATION SYSTEM HAVING THE SAME

摘要

PURPOSE: A sun tracking apparatus and a sunlight irradiation system having the same are provided to achieve improved accuracy and efficiency of radiation and allow for a simplicity of structure. CONSTITUTION: A sun tracking apparatus comprises a sensor unit(62) connected to a sunlight receiving unit, and which includes a plurality of optical sensors(64d), a horizontal separator wall for separating two or more optical sensors in a horizontal direction, and a vertical separator wall for separating two or more optical sensors in a vertical direction; a driving unit(30) for moving the sunlight receiving unit and the sensor unit; and a control unit for processing the signal output from the sensor unit and transmitting the signal for controlling the driving unit. The control unit includes an error measurement circuit portion and a control circuit portion. The driving unit includes a vertical rotating shaft(34), a horizontal rotating shaft(36), and first and second motors(38,40).
