As a fourth generation lighting source, LED has many characteristics different from other electric light, which makes energy-saving light source of choice. Applied to the field of plant cultivation LED also showed the following characteristics: rich wavelength type, coinciding with the optical combining plants spectral range coincide; width at half-wave spectral width can be obtained with pure monochromatic light spectrum as required complex combinations; you can concentrate specific wavelengths of light irradiation balanced crop; not only can adjust the crop flowering and strong, but also to control plant height and plant nutrients; less heat system, small footprint, can be used for a combination of three-dimensional multi-layer cultivation system, to achieve a low heat load and small production space; in addition, its exceptionally strong durability also reduces operating costs. Because of these significant features, LED is suitable for a controlled environment plant cultivation facilities, such as plant tissue culture, Horticulture industrialized breeding and Space ecological life support systems.
LED Grow Light Features:
1, different wavelengths of light for photosynthesis of plants influence is different, plant photosynthesis needs light, at a wavelength of about 400-700nm. 400-500nm (blue) light and 610-720nm (red) for the largest contribution to photosynthesis.
2, blue (470nm) and red (630nm) of the LED, just to provide light for plants, so the ideal option is to use a combination of the two colors. The visual effect, the combination of red and blue light pink color plant.
3, blue light helps to promote leaf growth plant photosynthesis, protein synthesis and the formation of the fruit; red light to promote the growth of plant roots, flowering and helps extend the flowering period, played a role in increasing the yield!
4, the proportion of red and blue LED lights LED plant is generally from 4: 1 to 9: 1, usually optional 6-9: 1.
5, when the plants fill light lamp to the plant, the general distance blade height of about 0.5-1 m, 12-16 hours per day continuous exposure can completely replace the sun.
6, the effect is very significant, growing nearly three times faster than the natural growth of plants in general.
7 to address the lack of sunlight in winter greenhouses annoying, promote chlorophyll and carotenoids photosynthesis in plants needed to make fruits and vegetables harvested in advance 20% of the time, to increase 3-5 percent of production, but also to improve the sweet fruits and vegetables degrees and reduce pests and diseases.
8, LED light source known as a semiconductor light source, relatively narrow wavelength of this light source can emit light of a specific wavelength, it is possible to control the color of the light. It plants with irradiation alone, we will be able to improve plant varieties.
9, LED grow light power is small, but highly efficient, because the other light emitted from the whole spectrum, that there are seven colors, and the plant needed but only red and blue light, so most of the energy of traditional lights have waste, so efficiency is very low. The LED grow lights can emit plants need specific red and blue light, and therefore extremely efficient, which is why LED Grow Lights few watts or even hundreds of watts lamp effect better reason than the tens of watts. Another reason is the lack of the traditional sodium lamp inside the blue spectrum, while mercury and energy efficient lighting inside and lack of red light spectrum, so the traditional lamp fill light than LED lights lot worse, but compared to the traditional lights to save electricity more than 90%, run costs are significantly reduced.
