A kind of plant growth lamp of tool situation variation of what is closed in this creation system, and a basin body is equipped with accommodating space, water space and loudspeaker. One lampshade is equipped with a fixed space. One light illuminating unit is equipped with a circuit substrate, top, the bottom of the circuit substrate are respectively equipped with plural first light-emitting component and the second light-emitting component, the circuit substrate controls first light-emitting component and issues the light of different colours, and controls the light that second light-emitting component transformation issues different wave length. One water supplying unit receives the control of the light illuminating unit, which is equipped with a water pipe, which is equipped with water outlet towards the accommodating space. One power supply unit for should loudspeaker, light illuminating unit, water supplying unit and sensor electric power. One sensor is incuded, and is the situation variation for triggering the loudspeaker, light illuminating unit and water supplying unit and generating simulation climate.本創作係關於一種具情境變化之植物成長燈，一盆體設有容置空間、儲水空間及喇叭。一燈罩設有一固定空間。一光照單元設有一電路基板，該電路基板之頂、底部分別設有複數第一發光元件及第二發光元件，該電路基板控制該第一發光元件發出不同顏色的光線，又控制該第二發光元件變換發出不同波長之光線。一供水單元接受該光照單元之控制，該供水單元設有一水管，該水管設有出水端朝向該容置空間。一供電單元供應該喇叭、光照單元、供水單元及傳感器之電力。一傳感器受到感應，係觸發該喇叭、光照單元及供水單元產生模擬氣候之情境變化。
