The present invention relates to an LED plant factory. According to the present invention, a solar power generating part, which is not a fixated building structure but a structure capable of moving forward and backward, is built on a non-construction site formed by obeying regulations of the floor area ratio and the coverage ratio for the building around a site in which the LED plant factory is built. Therefore, not only the LED plant factory can provide electric power but also the non-construction site can be efficiently used as an installation space for the solar power generating part capable of being moved forward and backward.COPYRIGHT KIPO 2014본 발명은 LED 식물공장에 관한 것으로서, LED 식물공장이 건축된 대지 주변에 용적률과 건폐율에 따라 발생된 비건축대지에 고정건축구조물이 아닌 전후이동가능한 태양발전부를 설치하여 상기 LED 식물공장으로 전원을 공급할 수 있을 뿐만 아니라 비건축대지를 전후이동가능한 태양발전부 설치공간으로서 보다 효율적으로 사용할 수 있는 효과가 있다.
