PURPOSE: A plant factory system is provided to enhance the crop yield per unit cell part according to effectively using spaces in for raising crops inside of the cell part. CONSTITUTION: A lighting part(200) is arranged inside of the cell part and irradiates light with rotation. A main supporter(110) is arranged in the center of cell part. A lighting part wedged in a main supporter rotates and comprises a rotator which center is supported by the main supporter. A rotating frame(210) is wedged in a main supporter. A rotating blade(220) is inserted into a formed groove of rotating frame and is detachable. A motor which rotates the rotating wing by generating driving force is installed inside of a main supporter. A lamp irradiates light to the crops. A reflector mounted on a lamp, reflects the light emitted from the lamp toward the direction of crops. A cell part comprises an upper side and a bottom side of polygonal shape and a side which connects a upper side and bottom side. A cutting means is mounted on a rotating wing and cuts the crops. A rotating body controls a fixed light quantity for crops by controlling the rotation speed. A sensor senses camera which takes pictures of crops image, temperature, humidity, and light quantity when rotating wing rotates. A fan(230) circulates the heat generated from a lighting lamp to the external of a rotating wing.본 발명의 식물공장 시스템은, 다각형 형상의 상면과 하면, 및 상기 상면과 상기 하면을 연결하는 측면으로 구성되는 셀부의 내부 공간에 배치되고, 회전하면서 광을 조사하는 조명부를 포함하고, 상기 셀부의 중앙에는 주지지대가 배치되어 있고, 상기 조명부는 상기 주지지대에 끼워져 회전하고 상기 주지지대에 의해 중심이 지지되는 회전체를 포함하고, 상기 회전체는, 상기 주지지대에 끼워진 회전 프레임； 및 상기 회전 프레임에 형성된 홈에 삽입되어 고정되고, 탈착 가능한 회전날개；를 가진다.
