How does LED make up the plant

   

Plants need sunlight to grow more luxuriantly. The role of light in plant growth is to promote chlorophyll uptake by plants, such as carbon dioxide, water and other nutrients, and to synthesize carbohydrates. But modern science can make plants grow better in the absence of the sun. People have mastered the intrinsic principle of the plant for the sun, that is the photosynthesis of the leaves. In the leaf photosynthesis, the whole process of photosynthesis can be accomplished by the excitation of the outside photons. The sun light is a process of photon energy supply. The artificial creation of light sources can also allow plants to complete photosynthesis, and modern horticulture or plant plants are combined with supplemental lighting technology or complete artificial light technology. Scientists found that the blue and red areas are very close to the efficiency curve of plant photosynthesis, and are the best light source for plant growth.


Plant light knowledge:


1. the effects of different wavelengths of light on plant photosynthesis are different. The light needed for photosynthesis is about 400-700nm. The light of 400-500nm (blue) and 610-720nm (red) contribute most to photosynthesis.


2. the LED of blue (470nm) and red (630nm) just provides the light needed for plants, so the ideal choice for the LED plant lamp is to use these two combinations of colors. On the visual effect, the red and blue combination of plant lamps is pink.


3. blue light promotes the growth of green leaves; red light helps to blossom and prolong the flowering period.


The ratio of red to blue LED of 4.LED plant lamps is usually between 4:1--9:1, and 4-7:1 is usually optional.


5. when plant light is used to fill the plants, the height of the leaves is about 0.5 meters, and the continuous exposure to 12-16 hours a day can completely replace sunlight.


The LED semiconductor bulb is used to configure the most suitable light source for plant growth.


The proportionate coloured lights can make strawberries and tomatoes more sweet and nutritious. Using light to irradiate Holly seedlings is to mimic the photosynthesis of plants outside. Photosynthesis refers to the process that green plants use the chloroplasts to convert carbon dioxide and water into organic substances stored in energy and release oxygen through the chloroplasts. Sunlight is made up of different colors of light. Different colors of light play different roles in plant growth.


LED light source is also called semiconductor light source, which has a relatively narrow wavelength and can control the color of light. Using it to irradiate plants individually can improve plant varieties.


The seedlings of holly grown in purple light are the tallest, but the leaves are small and shallow, with a malnutrition. The seedlings under the yellow light are not only dwarf, but also the leaves are lifeless. The growth of holly under red and blue light is best, not only strong, but also highly developed. The red light bulb and blue light bulb of the LED light source are arranged in proportion to 9:1.


The results showed that the red and blue light of 9:1 was the most favorable for plant growth. After this light source, the fruit of strawberry and tomato was full, the content of sugar and vitamin C increased obviously, and there was no hollow phenomenon. Daily exposure to 12— for 16 hours, strawberries and tomatoes grown under such a light source will be more delicious than ordinary greenhouses.


LED plant growth lamp can also be used for light source in winter under rainy weather.


The company produces all kinds of LED plant growth lamp products.

LED plant growth lamp adopts imported chip, which has high luminance and low light attenuation and high energy efficiency. It can promote plant growth obviously and have the characteristics of extremely low consumption and long life. It is not comparable to other ordinary light filling lamps. It is widely used in plant cultivation places and other lighting use, which can replace the sunlight to indoor flowers and greenhouse vegetables. Vegetables, garden nursery and other supplementary light to encourage, regulate flowering, survival and so on. The effect of filling light is superior to that of high pressure sodium lamp, low pressure sodium lamp, metal halide lamp, PHILPS plant light and rare earth plant light.
