What are the characteristics of LED plant lights

1. The effect of different wavelengths of light for plant photosynthesis is different, and the lights needed for plant photosynthesis, and the wavelength is around 400-700 nm. 400-500 nm (blue) light and 610-720 nm (red) have the greatest contribution to photosynthesis.
2, blue (470 nm) and red (630 nm) LEDs, just provide the light needed to provide plants, so the ideal choice is to use these two colors. In the visual effect, the red-blue combined vegetable lamp presents pink.
3, blue light helps plant photosynthesis can promote green leaf growth, protein synthesis, fruit formation; red light can promote plant root growth, help flowering results and prolong the flowering period, play an increase in production!
4, the proportion of red-blue LEDs of LED plant lamps is generally between 4: 1-9: 1, usually available 6-9: 1.
5. When using a plant lamp to fill the plant, the height of the blade is generally 0.5-1 meters, and it can be completely replaced by 12-16 hours daily.
6, the effect is very significant, the growth rate is far less than 3 times faster than the natural growth plant.
7. Solve the trouble of lack of sunshine in the greenhouse, promote the chlorophyll, anthocyanins and carotenoids required for plant photosynthesis, so that fruits and vegetables have been collected by 20% early, increased from 3 to 5%, and increase the sweetness of fruits and vegetables. Degree and reduce pests and diseases.
8, the LED light source is also known as the semiconductor source, which is relatively narrow, and the light of a particular wavelength can be transmitted, so that the color of the light can be controlled. It can be improved by using it separately for plants to improve plant varieties.
9, LED plant growth lamp power is small, but the efficiency is extremely high, because other lights are full, there are seven colors, while the plants need only red and blue light, so the traditional lights are mostly light energy Wasted, so the efficiency is extremely low. The LED plant growth lamp can emit a particular red and blue light, which is extremely efficient, which is why LED plant growth lights have a good reason for the power of dozens of watts or even hundreds of tiles. Another reason is that there is a lack of blue light in the traditional sodium light spectrum, while the mercury lamp and the energy-saving light spectrum are lack of red light, so the traditional lamp fill the light is much better than the LED light, but also compares more than 90% of the electric energy, run The cost is greatly reduced.
