Overview and Specifications:
The main reason is that the lack of light irradiation, through the LED lamp suitable for the desired spectrum of plants, can not promote its growth, but also can extend the flowering period, improve the quality of flowers.
To further apply this high-efficiency light source system to agricultural production such as greenhouses and greenhouses, on the one hand, it can solve the drawbacks of the greenhouse vegetables, such as tomatoes and cucumbers, that are degraded due to lack of sunshine, and can reduce the taste of greenhouse vegetables. Listed before and after the Spring Festival to achieve the purpose of anti-season cultivation.
1. Effect of spectral range on plant physiology
280 ~ 315nm: minimal effect on morphology and physiological processes
315 ~ 400nm: Absorption of chlorophyll, affecting photoperiodic effects, preventing stem elongation
400 ~ 520nm (blue): The absorption ratio of chlorophyll and carotenoids is the largest and has the greatest impact on photosynthesis
520 ~ 610nm (green): Absorption rate of pigment is not high
610 ~ 720nm (red): Absorption rate of chlorophyll is low and has significant effects on photosynthesis and photoperiodic effects
720 ~ 1000nm: Low Absorption Rate, Stimulates Cell Prolongation, Affects Flowering and Seed Germination
>1000nm : Convert to Heat
Currently, the special wavelength LED provided by the company is 615-620-625-630nm in red, 400-405-410-415-420-425-430nm in purple, and 450-455-460-465-470NM in blue. :490-500nm 520-525NM Infrared with 680-690-700NM, Applied to Plant Lights
2. From the above data, the effects of light of different wavelengths on the photosynthesis of plants are different. The light required for photosynthesis of plants ranges from 400 to 720 nm. Light from 400 to 520nm (blue) and 610 to 720nm (red) contribute the most to photosynthesis. Light from 520 to 610 nm (green) is absorbed by plant pigments at a very low rate. Experiments show that red light (610 ~ 720nm) greatly increases the cooperation of plants and promotes plant growth; blue light (400 ~ 520nm) can enhance chloroplast activity and promote plant photosynthesis; purple light (300-440nm) promotes the formation of plant pigments And the absorption of phosphorus and aluminum directly affects the vitamin D, the formation of stratum corneum, and the accumulation of dry matter in plants and fruits. Under the mixed light of red and blue (9:1), the growing holly grows best, not only is strong, but also has a strong root system.
4, white LED lights, the most common is the use of blue core, excitation yellow phosphor, resulting in a composite white light effect. In terms of energy distribution, there are two peaks in the blue region of 445 nm and the yellow-green region of 550 nm. The 610 ~ 720nm red light required by plants is very scarce. This explains why plant growth is unfavorable under white LED illumination.
5, usually choose 7 ~ 8:1 ratio. Of course, it is best to adjust the proportion of red and blue light according to the plant growth cycle. In the visual effect, the red and blue combination plant lights are pink
6, when the plant light is used to fill the plants, the height of the blade is generally 0.5 to 1 meter.
LED led light has a small calorific value, can be close to the light of plants, does not cause burns, and can be arranged between rows of plants or ridges to minimize the loss of light leakage and improve light efficiency.
Small size, long life, high bio-energy efficiency, energy saving and environmental protection, and no heavy metal pollution after damage, is a green lighting source, very suitable for green production.
The 300W LED plant light's physiologically effective radiation energy is equivalent to 800W of the HPS, which saves about 80% of the electric energy compared with traditional lighting fixtures, reduces the cost of supplementing light, and has significant economic benefits.
Applicable environment -40°C-70°C
General plant fill light. Suitable for the blooming of the light, the result of the leaflet plants or aquatic plants, etc.
