Plant Fill Light
LED plant light features
The effects of different wavelengths of light on plant photosynthesis are different. The light required for plant photosynthesis has a wavelength of about 400-700 nm. Light from 400-500 nm (blue) and 610-720 nm (red) contribute the most to photosynthesis.
Blue (470nm) and red (630nm) LEDs just provide the light needed by the plant, so the ideal choice is to use these two color combinations. In terms of visual effects, the red and blue combination plant lights appear pink.
Blue light helps plant photosynthesis promote green leaf growth, protein synthesis, and fruit formation; red light can promote plant roots growth, contribute to flowering results and prolong flowering, and increase yield!
The ratio of red and blue LEDs of LED plant lights is generally between 4:1 and 9:1, usually 6-9:1.
When the plant light is used to fill the plant, the height of the blade is generally about 0.5-1 meters, and the continuous irradiation for 12-16 hours per day can completely replace the sunlight.
The effect is very significant, and the growth rate is almost three times faster than the plants that grow naturally.
Solve the lack of sunshine in the greenhouse in winter, promote the chlorophyll, anthocyanin and carotene needed in plant photosynthesis, so that fruits and vegetables can be harvested 20% earlier, increase the yield of 3 to 50%, and increase the sweetness of fruits and vegetables. Reduce pests and diseases.
LED light source is also called semiconductor light source. This kind of light source has a relatively narrow wavelength and can emit light of a specific wavelength, so it can control the color of light. It can be used to improve plant varieties by using it alone.
LED plant growth lamps have low power, but they are extremely efficient, because other lights emit full spectrum, that is, there are 7 colors, and plants only need red and blue light, so most of the traditional light is wasted. So the efficiency is extremely low. The LED plant growth lamp can emit the specific red and blue light that the plant needs, so the efficiency is extremely high, which is why the power of the LED plant growth lamp is better than that of the tens of watts or even hundreds of watts. Another reason is that the traditional sodium lamp spectrum lacks blue light, and the mercury lamp and the energy-saving lamp spectrum lack red light, so the traditional lamp fill light effect is much worse than the LED lamp, and the traditional lamp needs to save more than 90% of the energy, running The cost is greatly reduced.
Advantages of LED plant lights
A standard power outlet connector for the drive or cooling fan is not required.
An environment in which red and blue wavelengths are required for plant growth.
Compared with other general lighting equipment, LED plant light lines are mild and do not burn the seedling plants.
It can save 10%~20% of electricity bills compared with other plant lighting.
Blue light can promote the growth of plants, while red light causes plants to bloom.
