植物工廠係指在封閉的栽培設施環境下，實現對於植物生長環境與營養需求提供最佳化精準調控的栽培體系，藉由高科技的設備控制並配合對植物生長狀況進行觀察，以達到無季節氣候限制、全年無休、無農藥殘留的計畫性植物量產。現今市面上的植物工廠將燈具橫置於植物生長箱上方，單一方向光源造成溫室內各處的亮度難以均一，不僅使植株整齊度降低、造成空間利用率下降，同時無法針對單一植物作光強度的調整。本系統針對植物工廠用新型RGB LED驅動電路及光配方調控系統進行開發，為了研究直立型燈具是否能提高植物的空間利用率或提升植株整齊度，本系統以4組直立式燈具組取代橫式燈具，藉由所開發之應用程式作燈光顏色調控。本系統除了操作簡單之外，所開發之應用程式讓使用者得以自行調整燈具顏色，更可針對單一植物藉由系統自動計算輸出最合適的燈光配置，同時便利地記錄植物生長情形。

The plant factory is an indoor facility that aims to steadily produce high-quality vegetables all year round by artificially controlling the cultivation environment (e.g., light, temperature, humidity, water, carbon dioxide concentration, etc.), allowing the production be planned by growers. The growing cycles are consistent and reliable with the protection from weather-related problems. Of the various environmental factors that controls plant development, light plays an especially important role. Nowadays, the lighting system used in the plant factory is usually placed above the plants, which lower the plant spacing uniformity due to the uneven illumination caused by the directional lights. Simultaneously, the space utilization is therefore becoming lower. In this thesis, a novel LED lighting system mainly for plant factory is developed. To know whether the proposed vertical lighting system works well for improving spacing uniformity and utilization or not, the vertical LED lamps are adopted as the replacement. By applying the developed mobile application software (App), not only the lights can be operated under either users demands or system calculation, but the growth conditions of plants can be readily recorded. The proposed system has the advantages of easy installation and simple operation.
