To solve the agricultural damages caused by the climate change, this study is developed to build an automatic supplementary lighting platform for plant factories. The platform mainly uses aluminum as materials. The lighting strategy will depend on the DPI. During the day, platform parked at the original position and uses quantum sensor to accumulate the daylight. At night, it moved to the supplementary lighting area and provides lighting to plants. The platform is operated in cooperation with a PLC control system, and uses RFID and limit switch as a local positioning system at plant factories. In supplementary lighting area, lifting system detects the height of plants to adjust the level of lampshade accordingly. The study operated 10 times movement experiments, after first 5 times calibration, the success rate of last 5 times moving positioning is 93%, and the success rate of 10 times lifting experiments is 98%. The platform can provide an average of 354 μmol /㎡ /s light intensity within the distance of 10cm from the plants, and 3.27 μmol CO<sub>2</sub> / ㎡ / s if it is within the photosynthesis characteristic of lettuce. Based on the results of two-week experiment, it can be confirmed that supplementary lighting is able to provide sufficient lighting to plants during the night, and reach DPI standard of each supplementary lighting area.
