Summary:To achieve long life of an LED for inhibiting a pest.SOLUTION: A lighting control device 3 for a plant factory comprises: a reception part 31 which receives a carbon dioxide concentration measured by a sensor 1 disposed around a plant 8; a determination part 32 which determines the growth stage of the plant 8 by using the carbon dioxide concentration; and a control part 33 which controls ON and OFF of an LED lighting 92 which irradiates the plant with ultraviolet light which inhibits a pest. The control part 33 controls ON and OFF of the LED lighting on the basis of the upper limit and the lower limit of the cumulative irradiation of the LED lighting 92 set for each growth stage.SELECTED DRAWING: Figure 1 【課題】病害虫を抑制するＬＥＤを長寿命化する。【解決手段】植物工場用の照明制御装置３であって、植物８の周囲に配置されたセンサ１が計測した二酸化炭素濃度を受信する受信部３１と、二酸化炭素濃度を用いて植物８の生育段階を判定する判定部３２と、病害虫を抑制する紫外光を前記植物に照射するＬＥＤ照明９２のオンおよびオフを制御する制御部３３とを備え、制御部３３は、生育段階毎に設定されたＬＥＤ照明９２の積算照射量の上限値および下限値に基づいて、前記ＬＥＤ照明のオンおよびオフを制御する。【選択図】図１
