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. There are 450-455-460-465-470NM blue green with : 490-500nm 520-525NM Infrared with 680-690-700NM, used in plant lights

2, from the above data, the different wavelengths of light for plant photosynthesis is different, plant photosynthesis requires light, wavelength in 400 ~ 720nm. 400 ~ 520nm (blue) light and 610 ~ 720nm (Red) contributes the most to photosynthesis. 520 ~ 610nm (green) light, the rate of absorption of plant pigment is very low.Experiments show that: red light (610 ~ 720nm) greatly increased plant cooperation and promote plant growth; (400-420nm) can promote chloroplast activities and promote plant photosynthesis; purple light (300-440nm) to promote the formation of plant pigments and phosphorus and aluminum absorption, a direct impact on plants and fruits of vitamin D, cuticle formation and Dry matter accumulation in the red and blue (9: 1) mixed light, the growth of holly growing the best, not only strong, the root system is also very well developed in accordance with the above principle.

3, in accordance with the above principles, the basic plant lights are made of red and blue combinations, all blue, red three forms to provide red and blue wavelengths of light, covering the required wavelength range of photosynthesis in the visual effects, The red and blue combination of plant lights pink.
4, white LED lights, the most common is to use the blue core to stimulate the yellow phosphor, which combined to produce visual white light effect.Energy distribution, the 445nm blue and 550nm yellow-green zone there are two peaks , While the plants need 610 ~ 720nm red light, is very lacking.This explains why the white LED irradiation, plant growth disadvantage.
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 the plant light to the plant fill light, the general distance from the blade 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 energy efficiency, energy saving and environmental protection and damage without heavy metal pollution, is a green lighting 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 to 70 ° C
Applicable plant general fill light. The most suitable for hi light will flowering, the results of leaflets or plants such as plants
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 uptake, increase crop yield and quality; maintain healthy plant growth, avoid leggy or lack of dwarfing.
