With the increase of global LED applied agricultural lighting penetration, LED plant lighting, as a new market, attracts a large number of international giants to invest and develop. In fact, the application of LED plant lights is of great significance, both from the perspective of promoting the development of modern agriculture and the realization of food safety and climate change.
In order to accelerate the harvest of crops, enterprises often need to develop the light source and lamps needed for plant growth according to the light formula, in order to effectively improve the utilization of light energy and harvest the fruits. In fact, there are three main factors affecting plant growth: light quantity (light intensity), light quality (spectral range), and photoperiod. As long as the light source ratio is perfect, it can provide the best growing environment for plants.
However, in addition to the above three factors, Photosynthetic Photon Flux Density(PPFD) is more important for plant growth control. What is PPFD? It means how many photons hit a defined area(400~700nm) in one second. Plant has various species and different categories which have different PPFD requirements. The light intensity has valuable effects on the plant due to the different wavelengths. Therefore, if you can use the spectrometer to intuitively understand the light source quality of the plant lamp and master the spectral changes of different bands, you can adjust the artificial light source in time and achieve remarkable results.
