The present invention is a lighting device for plant growth, it is composed of a blue LED chip as the light source with different colors of phosphor powders. The wave length of blue chip falls in the range of 440-460 nm which stimulates stoma opening to absorb carbon dioxide. By formulating the right recipe of phosphors, the emitted light will have the spectra very close to that of light necessary for plant photosynthesis. It has the combined functions of good plant photosynthesis, stoma opening stimulation and some photomorphogenesis in one single device. It is a very prominent invention of artificial lights for plant growth ever seen. |
