1, the spectral range of plant physiology
280 ~ 315nm: the shape and physiological processes of the impact of minimal
315 ~ 400nm: less absorption of chlorophyll, affecting the photoperiod effect, to prevent stem elongation
400 ~ 520nm (blue): chlorophyll and carotenoid absorption ratio of the largest, the greatest impact on photosynthesis
520 ~ 610nm (green): the absorption rate of pigment is not high
610 ~ 720nm (red): chlorophyll absorption rate is low, the photosynthesis and photoperiod effect has a significant impact
720 ~ 1000nm: low absorption rate, stimulate the cell to extend, affecting flowering and seed germination
> 1000nm: converted to heat
At present, the company provides a special wavelength LED, red 615-620-625-630nm, purple 400-405-410-415-420-425-430nm. Blue has 450-455-460-465-470NM green : 490-500nm 520-525NM Infrared with 680-690-700NM, used in plant lights

2, from the above data, different wavelengths of light for plant photosynthesis is different, plant photosynthesis needs light, wavelength of about 400 ~ 720nm. 400 ~ 520nm (blue) light and 610 ~ 720nm (Red) for the photosynthesis contribution of the largest. 520 ~ 610nm (green) light, the rate of absorption of plant pigment is very low.Experimental results show that: red light (610 ~ 720nm) greatly increased plant cooperation, promote plant growth; (300-440nm) to promote the formation of plants and the absorption of phosphorus and aluminum elements, a direct impact on plant and fruit of vitamin D, the formation of stratum corneum and the formation of the skin, and the growth of chlorophyll, Dry matter accumulation, while in the red and blue (9: 1) mixed light, the growth of holly grows the best, not only strong, the roots are also very developed. Led plant growth lamp is refined in accordance with the above principles.

3, in accordance with the above principles, plant lights are basically made of red and blue combination, full blue, all red three forms to provide red and blue wavelengths of light, covering the wavelength range required for photosynthesis in the visual effects, Red and blue combination of plant lights appear pink.
4, white LED lights, the most common is the use of blue core, to stimulate the yellow phosphor, which produced a composite effect of white light. Energy distribution, in the blue area of ​​445nm and 550nm yellow-green area there are two peaks And the plant 's desired light of 610 to 720 nm is very low, which explains why plant growth is not good at white light.
5, the plant blue and blue lamp color ratio is generally between 5: 1 ~ 10: 1 is appropriate, usually 7 to 8: 1 ratio, of course, conditional according to the plant growth cycle to adjust the red and blue light The best proportion.
6, with plant lights to fill light plants, the general distance from the height of 0.5 to 1 meter
LED plant light (led grow light) of small heat, can be close to the plant fill light, does not cause burns, can be arranged in the plant line or between the ridge, to minimize the loss of light loss, improve light efficiency.
Can be based on the needs of different growth stages of plants, combined with LED spectrum to obtain pure monochromatic light or composite wavelength to fill light, promote plant growth, flowering, the results.

Small size, long life, high bio-energy efficiency, energy saving and environmental protection and no heavy metal pollution after the damage, is a green light source, very suitable for green production.
300W LED plant light physiological radiation is equivalent to 800W HPS, than the traditional lighting to save about 80% of the energy, reduce the cost of light, significant economic benefits.
Applicable environment -40 ° C-70 ° C
Applicable to plant general fill light. The most suitable hi light will flowering, the results of leafy plants or aquatic plants, etc.
Use for the lack of light or mediation of the growth period of flower cultivation, vegetable cultivation, aquatic (aquarium) breeding and other places, used to fill the plant light, promote, mediation growth period is a good helper for science and technology agriculture!
This baby can replace the sun to the flowers, fruits, vegetables, plants and other fill light, used to promote the leaves of plants, long stems, flowering, the results; promote plant photosynthesis and nutrient absorption; adjust the flowering and color of plants; Nutrient absorption, improve crop yield and quality; to maintain the healthy growth of plants to avoid leggy or lack of dwarfing.
