Among all the light waves that exist in nature, red-orange light and blue-violet light are most absorbed by green plants for photosynthesis. In addition, there is a small amount of absorption of green light, yellow light, and orange light.
Among the early visible light, red light has a wavelength of about 630nm-780nm, which is the first light quality used in crop cultivation experiments. Among all the light quality needed for photosynthesis for plant growth, the demand for red light is also the largest.
When manufacturing LED plant lights, the most important thing is LED plant light chips, and in most cases, the number of red LED plant light chips is more than the number of blue LED plant light chips.
Plants undergo photosynthesis under the red light of LED plant lights, and the substances produced can promote plant growth, especially the growth of plant stems, and at the same time promote carbohydrate synthesis, which is also conducive to the synthesis of sugar and VC from fruits and vegetables. However, at the same time It also inhibits plant nitrogen assimilation.
The red light of LED plant lights regulates light morphogenesis by adjusting photosensitizing pigments, which affects the differentiation and division of plant cells. This feature of red light on plants can help plants complete morphology on the one hand, and can also effectively prevent overgrowth and improve the quality of crops. Better, higher output.
Not only plants have requirements for light quality, but animals also have requirements for light quality. Putting a person in a monochromatic red light environment is not only a visual discomfort, but also the body and metabolic functions. It is precisely because With such characteristics, LED plant lights can not only help plants grow, but also repel insects and diseases.
