The plant disc with adjustable spectrum of at least four kinds includes a disc body.And a control device electrically connecting the optical disc main body；Among them,The control device has a frequency conversion device which is electrically connected with the optical disc main body.And a communication interface electrically connecting the frequency conversion device；The main body of the disc has a plurality of lamp beads.Each lamp bead includes a plurality of spectral generators with different spectra.And the spectrum generator can emit at least 4 kinds.Even more than 16 spectra,And each lamp bead is electrically connected with the frequency conversion device.And the frequency conversion device can adjust and control the spectrum generator in the lamp bead independently or in combination；Adjust the spectrum generator of each different spectrum through the frequency converter.The emitted light of each lamp bead can be evenly mixed.So that the creation can more accurately simulate the situation of sunlight.本創作可調變至少四種以上光譜的植物光盤包含一光盤主體，以及一電性連接該光盤主體之控制裝置；其中，該控制裝置具有一電性連接光盤主體之變頻裝置，以及一電性連接變頻裝置之通訊介面；該光盤主體具有複數個燈珠，且每一個燈珠包括複數個具有不同光譜的光譜產生器，而該光譜產生器可發射至少4種以上、甚至16種以上的光譜，而前述每一燈珠係與變頻裝置電性連接，且該變頻裝置可單獨或複合調控燈珠中的光譜產生器；透過變頻裝置調變每種不同光譜的光譜產生器，即可將每一燈珠的發射光均勻混合，使本創作可更精準模擬太陽光照射之情境。
