A circuit structure for changing the spectrum of light-emitting elements of plants or aquarium plants, which includes a first voltage stabilizing circuit, a first input and a first output； a microcontroller, which is electrically connected with a first output, and a microcontroller, which is electrically connected with an operating circuit and a complex power adjusting circuit, each power adjusting circuit is provided with an eighth input and an eighth transmission And the eighth output end of each power adjusting circuit is electrically connected with a light-emitting element, and the power adjusting circuit is provided with a second input end.The power of each light-emitting element can be adjusted by MCU and operation circuit, which can not only make single color light and adjust the brightness ratio of light source at the same time, but also produce the red and blue light with a specific proportion of spectrum matching. When the plant is supplemented with light to irradiate and grow, the creation can achieve accurate variable spectrum matching. The utility model is suitable for the growth demand of each plant.一種用於植栽物或水族箱植栽物補光的可變其發光元件光譜的電路結構，其包含第一穩壓電路，係設有第一輸入端和第一輸出端；微控制器，係電性連接第一輸出端，且微控制器電性連接操作電路和複數功率調整電路，該每一功率調整電路設有第八輸入端和第八輸出端，且該每一功率調整電路之第八輸出端電性連接一發光元件，該等功率調整電路設有第二輸入端。藉由微控制器(MCU)及操作電路並搭配該等功率調整電路對該每一發光元件進行調配功率，不僅可單一顏色發光並同時調整光源亮度比例，更可產生例如紅藍光以特定比例之光譜匹配之發光，對於植栽物進行補光照射生長時，俾可使本創作達到能精確的可變光譜匹配之功效，以適用每一種植栽物之生長需求。
