About LED plant light use:
Plants are inseparable from light, and light is an indispensable source of energy for plant growth. It is known that light regulates the photosynthesis, growth and development, morphogenesis and metabolism of plants. Currently, the light sources used to make up for the loss of sunlight in greenhouses and greenhouses are generally fluorescent lamps, high-pressure sodium lamps, and incandescent lamps. The spectral energy distribution of these light sources is designed based on the human eye's demand for light, and plant growth. The spectrum needed is different from the needs of the human eye. However, the types of LED wavelengths are abundant, and there is a large range of controllable illumination, which is suitable for the lighting of plants.
Different wavelengths of light have different effects on the photosynthesis of plants, and plant photosynthesis requires wavelengths of light in the range of 400 to 720 nm. Light from 400 to 520 nm (blue) has the largest proportion of chlorophyll and carotenoids, and therefore has the greatest effect on photosynthesis. Light from 610 to 720 nm (red) has a significant effect on photosynthesis and photoperiodic effects. 520 ~ 610nm (green) light, pigment absorption rate is very low. Therefore, plant lights are generally made into red, blue, all blue, full red three forms, usually red wavelength is selected at 620-630nm or 640-660nm, blue wavelength is selected at 450-460nm or 460-470nm. To provide both red and blue light, covering the range of wavelengths required for photosynthesis. In terms of visual effects, the red and blue combination plant lights appear pink.
   The ratio of the red and blue lights of the plant lights is generally between 5:1 and 10:1, usually 7 to 9:1.
  After application testing, the wavelength of LED plant lights is very suitable for plant growth, flowering, and results. General indoor plant flowers will grow worse and worse with time. The main reason is the lack of light irradiation, which can not only promote its growth, but also extend the flowering period and increase the flower's quality. The application of this high-efficiency light source system to agricultural production such as greenhouses and greenhouses can also solve the drawbacks of solar greenhouses, such as tomatoes, cucumbers, and other greenhouse vegetables.
Plant light knowledge:
1. The effects of light of different wavelengths on the photosynthesis of plants are different. The light required for plant photosynthesis has a wavelength of about 400-700 nm.
The 400-500 nm (blue) light and 610-720 nm (red) contribute the most to photosynthesis.
2. The blue (470nm) and red (630nm) LEDs just provide the light required by the plant. Therefore, the LED plant light is an ideal choice.
It is the use of these two color combinations. In terms of visual effects, the red and blue combination plant lights appear pink.
3. Blue light promotes the growth of green leaves; red light helps flowering results and extends flowering time!
4. The ratio of red and blue LEDs of LED plant lights is generally between 4:1 and 9:1, usually 4-7:1.
5. When plant lights are used to supplement plants, the height of the leaves is generally about 0.5 meters. Continuous irradiation for 12-16 hours per day can completely replace sunlight.
