1, the impact of spectral range on plant physiology
280 ~ 315nm: on the morphology and physiological process of minimal impact
315 ~ 400nm: less chlorophyll absorption, affecting the photoperiodic effect, to prevent stem elongation
400 ~ 520nm (blue): chlorophyll and carotenoid absorption ratio of the largest, the greatest impact on photosynthesis
520 to 610 nm (green): the absorption rate of the pigment is not high
610 ~ 720nm (red): chlorophyll absorption rate is low, the photosynthesis and photoperiodic effects have a significant impact
720 ~ 1000nm: low absorption rate, stimulate cell elongation, 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 proportion of red and blue lights of the plant lamp is generally 5: 1 ~ 10: 1 is appropriate, usually 7 ~ 8: 1 ratio, of course, can be adjusted according to the plant growth cycle of 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 the heat is small, can be close to the plant fill light, does not cause burns, can be arranged between the rows of plants or ridge to minimize the loss of light leakage, improve light efficiency.
According to the needs of different growth stages of plants, the combination of LED spectrum to obtain pure monochromatic light or compound wavelength 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 lights physiological and effective radiation equivalent to HPS 800W, than traditional lighting saves about 80% of the electrical energy, reducing the cost of fill light, significant economic benefits.
Applicable environment -40 ° C-70 ° C
Applicable to plant general fill light. The most suitable light will flowering, the results of leaf plants or aquatic plants, etc.
Application It is suitable for planting flowers, vegetables, aquatic plants and aquatic plants in the lack of light or mediation.
This baby can replace sunlight for flowers, fruits, vegetables, aquatic plants such as fill light, used to promote plant leaves, 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.
