PURPOSE: A building-integrated photo voltaic device for shielding light is provided to secure optimum lighting and shading effects by appropriately controlling the width and size of a solar battery module. CONSTITUTION: A building-integrated photo voltaic device for shielding light comprises upper and lower structures, a solar battery module(2), a servo motor(30), a lead screw(31), a rod, a shaft pin, and a fixing member(34). The upper and lower structures are protruded from the front of a window of a building. The solar battery module is installed in the upper and lower structures. The servo motor powers the solar battery module. The lead screw converts the rotation of the servo motor into a linear reciprocating motion. The rod is installed in the end of the lead screw. The shaft pin is installed in the solar battery module. The fixing member fixes the lead screw. |
