The wavelength types are abundant, which coincides with the spectral range of plant photosynthesis and light morphology; the half-width of the spectral wave width is narrow, and the pure monochromatic light and the compound spectrum can be combined as needed; the light of a specific wavelength can be concentrated to irradiate crops; not only can adjust crops Flowering and fruiting, and can also control plant height and plant nutrients; the system generates less heat and occupies a small space. It can be used in a multi-layer cultivation three-dimensional combination system to achieve low heat load and miniaturization of production space.
