In the past, plants only grew according to seasonal changes, but today plants under LED plant lights can change the seasonal growth of plants. The seasonality of plant growth is controlled by artificial environment, and plant lights only complete the growth process of plants. If the environment does not change, the growth of the plant still depends on the season.
Plant factories are cross-border products, and plant lamp spectroscopy technology is an important link between planting equipment and planting technology. The planting process determines the spectral design, and the design and manufacture of the plant lamp is to ensure the optimum efficiency of the light quality required by the planting process. To understand the secret of LED plant lights, it is necessary to understand in depth what the spectrum of LED plant lights is.
The lighting micro-classroom specially invited Mr. Xu Dong from Foshan Haoliang Solid Light Source Research Institute to analyze the series of articles about plant lamp technology for us:
"Plant lighting is very hot, but do you really understand? 》
How to design LED spectrum of LED plants? 》
Below, we continue to learn the secrets of spectral data of LED plant lights.
Plants used to grow only on time, but now plants can change the growth cycle under LED lighting. Why? Research light starts from the spectrum. To understand the mystery of LED changes in plant growth, you must first know what the spectrum of LED plant lights is.
The basis of light research is spectrum. The application quality of light requires spectral analysis. The spectrum of LED plant lamps is particularly important. The manufacturer's ability to design the spectrum of plant lamps determines its market position. The LED plant lamp spectrum needs to be specially designed according to the planting process. To imitation.
The plant factory is a cross-border product. The research institute of the plant is divided into planting equipment technology and planting technology. The plant lamp spectrum technology is an important link between planting equipment and planting technology. It is necessary to clarify the planting process. Spectral design, the design and manufacture of plant lights is to ensure the best efficiency of the light quality required by the planting process. These characteristics of plant lights determine the complexity and diversity of plant spectral design.
Non-visual application of spectroscopy
Spectral applications are divided into visual applications and non-visual applications. Lighting is a visual application. Plant illumination is a non-visual application. Visual applications and non-visual applications have different physical dimensions. However, many plant lights are still used in lighting units. Labeling parameters, which can lead to cluttered parameter annotations, may come from the reference to "plant lighting."
The spectral study of plant photosynthesis is based on the distribution of optical radiation power or photon of the wavelength domain (spectral mass), which is achieved by spectral data and spectrograms.

Solar spectrum
Planting requires studying the solar spectrum. The solar spectrum tested on the ground belongs to the absorption spectrum. The standard solar spectrum is shown in Figure AM1.5G (G173-03). Due to the geographical location and season, the amount of spectral radiation measured on the ground will be There are differences, but the spectrum is the same.
