1.1 What is LED full spectrum plant growth lamp

        Plants need light for nutrient uptake. They use the energy of light for photosynthesis to obtain the necessary nutrients for growth and development.Therefore, photosynthesis is the key to the survival of plants.
        LED full spectrum is a kind of plant growth lamp with LED (light emitting diode) is a luminous body, using light instead of sunlight LED components, plant photosynthesis needs the artificial light illumination conditions, specifically promote plant photosynthesis, create suitable for plant growth and development of light environment designed with a specific spectral wavelength of special lamps and lanterns.In the absence of daylight, the lamps act as daylight, allowing plants to grow normally or better.This kind of lamps and lanterns has strong root, abet, adjust florescence, color, stimulative fruit is ripe, coloring, promote the action of mouthfeel and quality!
        Light environment is one of the important physical environmental factors indispensable for plant growth and development.The plant growth lamp has the function of environmental protection and energy saving, LED plant lamp provides photosynthesis for plants, promotes plant growth, reduces the time for plants to bloom and bear fruit, and improves production!In the modernization drive, it is an indispensable product for crops.

1.2 Photosynthesis in plants

        Photosynthesis function, namely, refers to the green plants and certain bacteria containing chloroplasts, under the irradiation of visible light, a light and carbon reaction (old dark reaction), use of photosynthetic pigment, the carbon dioxide is converted into organic matter (or hydrogen sulfide) and water, and release oxygen or hydrogen biochemical processes.There is also an energy conversion process that converts light energy into chemical energy in organic matter.
        For general green leaves, red and blue light with the wavelength of 660nm and 450nm as the center have the greatest impact on photosynthesis.

1.3 Effects of different spectra/light on plants

280 ~ 315nm : The effects on morphology and physiological processes are minimal
315 ~ 400nm :Chlorophyll absorption less, affect photoperiod effect, prevent stem elongation
400 ~ 520nm (Blue):The absorption ratio of chlorophyll and carotenoid was the largest and had the greatest influence on photosynthesis
520 ~ 610nm (Green):The absorption of pigment is not high
610 ~ 720nm (Red):Chlorophyll absorption rate is low, which has significant effect on photosynthesis and photoperiod effect
720 ~ 1000nm :Low absorption, stimulating cell elongation, affecting flowering and seed germination
>1000nm : Convert to heat

•Light quality: effect of Red light

1. Red light the main force of photosynthesis, which works best under certain blue light conditions;
2. In low-light environment, red light has the highest photosynthetic efficiency for plants;
3. Red light controls photoperiod and flowering rhythm Pr/Pfr -- affecting flowering;
4. Red light mainly helps plants produce carbohydrates, which make them grow taller and bigger.

610-680nm

•Light quality: the function of Blue light

1. In low-light environment, blue light has no stronger effect on plant photosynthesis than red light;
Blue light plays an important role in the early stage of plant growth and helps plants to establish a developed root system.
3. Blue light inhibits the growth of main stem and leaf, but increases the robustness of main stem;
4. Chlorophyll a/b has a strong absorption peak in the blue light region, which mainly helps plants to synthesize proteins and amino acids;
5. Proper blue light makes plants grow more balanced and healthier, and improves the quality of plant output.

420-470nm

•Light quality: effect of Green light

1. Green light has a certain effect of promoting plant photosynthesis;
2. In strong light environment (in combination with other light quality), green light plays a more important role;
3. Green light can penetrate the canopy and increase overall photosynthesis;
4. Green light can be neutralized by red and blue spectrum to reduce visual "light pollution", and the visual effect is good when light is mixed.

500-570nm

•Light quality: effect of UV light

1. Purple light is the central region of plant phototaxis and can affect plant morphogenesis;
2. Purple light inhibits the growth of main stem and leaf of plants (inhibits apophysis);
3. The purple light can stimulate the anthocyanin of plants, and promote the coloring of fruits/petals or leaves to improve the quality.

360-420nm

•Light quality: effect of IR light

1. Emerson effect (double light gain effect)
In 1957, biologist Robert Emerson discovered that the photosynthetic efficiency of green plants was much higher when red light (wavelength 660nm) and infrared light (wavelength >700nm) were irradiated together than when green plants were irradiated separately at 660nm.

2. Shade avoidance effect of plants
Infrared light is also the sensitive spectrum of phototaxis of plants. Under the irradiation of infrared light, plants feel that there are objects blocking the light at a high place and inhibiting their growth. They will strive to grow higher and promote the rapid growth of plants.

730-750nm
