Plant growth lamp belt -5050 waterproof - red and blue
Led plant light (led grow light) is using semiconductor lighting principle, dedicated to the flowers and vegetables and other plants with high precision technology, a auxiliary plant growth lamp. General indoor plants, flowers will grow more and more with the time difference, the main reason is the lack of light, through the spectrum of led light, suitable to plant needs not can promote its growth, can also extend the flowering time, improve the quality of the flower. Further the application of this kind of high efficient light source system to the big shed, greenhouse facilities, such as agricultural production, on the one hand can solve the sun led to the decrease of the tomato, cucumber and other greenhouse vegetables taste, on the other hand can also make the winter greenhouses solanaceous fruit vegetable to the market before and after the Spring Festival in advance, so as to achieve the aim of anti-season cultivation.
1. Influence of spectral range on plant physiology
280 ~ 315nm: little effect on morphology and physiological process
315 ~ 400nm: less chlorophyll absorption, affecting photoperiod effect, preventing stem elongation
400 ~ 520nm (blue) : the absorption ratio of chlorophyll and carotenoid is the largest, which has the greatest influence on photosynthesis
520 ~ 610nm (green) : the absorption rate of pigment is not high
610-720nm (red) : chlorophyll absorption rate is low, which has significant influence on photosynthesis and photoperiod effect
720 ~ 1000nm: low absorption, stimulating cell elongation, affecting flowering and seed germination
> 1000nm: converted to heat
2. According to the above data, light of different wavelengths has different effects on plant photosynthesis. The light required for plant photosynthesis has a wavelength of about 400 ~ 720nm. Light at 400-520nm (blue) and 610-720nm (red) contributed the most to photosynthesis. Light at 520 ~ 610nm (green) is absorbed very little by plant pigments. Experimental results showed that red light (610-720nm) greatly increased the cooperative use of plants and promoted their growth. Blue light (400 ~ 520nm) can enhance chloroplast activity and promote plant photosynthesis. Purple light (300-440nm) promotes the formation of pigments and the absorption of phosphorus and aluminum in plants, and directly affects the formation of vitamin D, cuticle and the accumulation of dry matter in plants and fruits. Under a mixture of red and blue (9:1) light, Holly grows best, is strong and has well-developed roots
4, white LED lights, the most common is the use of blue core, stimulate the yellow phosphor, which produces a composite visual white effect. In terms of energy distribution, there are two peaks in the blue region at 445nm and the yellow-green region at 550nm. The 610-720nm red light required by plants is very scarce. This explains why plants do not grow well under white leds.
5. The ratio of 7 to 8:1 is usually optional. Of course conditional can adjust the proportion of red and blue light according to plant growth cycle best. On visual effect, the plant lamp of red blue combination presents pink
6. When filling the light with a plant lamp, the general height from the leaf is 0.5 ~ 1 meter
LED grow light has low calorific value, can be close to the plant to fill the light, does not cause burns, can be arranged in the plant rows or rows, in order to minimize the loss of light leakage, improve light efficiency.
Small size, long life, high biological 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 physiological effective radiation energy of 300W LED plant lamp is equivalent to 800W of HPS, which saves about 80% of the electric energy compared with traditional lighting lamps, reduces the cost of light supplement, and has significant economic benefits.
Applicable environment to 40 ° C to 70 ° C
7.This is The Most Favorable LED configuration to promote the plant grow and flower:
Red 630-660NM+Blue 450-460NM+Orange 590-615NM White +3500-12000K.
