Everyone says LED plant lights are good? What is so good?


Plants need sunlight to grow more prosperous. The effect of light on plant growth is to promote plant chlorophyll to absorb nutrients, such as carbon dioxide and water to synthesize carbohydrates. But modern science can make plants grow better in places where there is no sun, but have LED plant lights. People have mastered the inner principle that plants need for the sun, which is the photosynthesis of leaves. The photosynthesis of leaves requires external photon excitation to complete the entire photosynthetic process. The sun’s rays are the energy supply process excited by photons.

Artificially created light sources can also allow plants to complete the photosynthetic process. Modern horticulture or plant factories are combined with supplementary light technology or complete artificial light technology. Scientists found that the blue light zone and the red light zone are very close to the efficiency curve of plant photosynthesis and are the best light sources for plant growth.maxbloom

1. What is the LED plant light?

As we all know, plants need light for nutrient uptake, and they use the energy of light for photosynthesis to obtain nutrients necessary for growth and development. Therefore, photosynthesis is the key to the survival of plants. LED plant light is a special light with a specific spectrum wavelength designed to replace sunlight with light emitted by LED light-emitting elements, to promote photosynthesis of plants and create a light environment suitable for plant growth and development.

2 . LED features plants lamps What?

The spectral wavelength required for plant photosynthesis is usually in the range of 400 ~ 720nm. The 400 ~ 520nm blue light and 610 ~ 720nm red light for photosynthesis, the largest contribution to the plant. The red and blue wavelengths of LED plant lights are just within this range, which can provide plants with spectral wavelengths suitable for their growth to promote plant growth. At the same time, LED plant lights are also energy-saving (high photoelectric conversion efficiency, power consumption is 1/4 of fluorescent lamps, 1/10 of sodium lamps ), spectral tunability, good point light source, cold light (low heat), good Features such as moisture resistance, small size and long life ( more than 30,000 hours). LED plant light supplement light technology will be the new trend and development direction of IT agriculture (science and technology agriculture) and urban facility agriculture.

3. What is the effect of using the LED plant light?

The LED plant light supplement light technology is a new technology that has emerged with the development of LEDs in recent years. A large number of research and application of LED plant growth lights in the facility cultivation environment show that it can solve the light quality of other artificial light sources. Impurity, inconsistent light intensity, and low energy efficiency of the light source. The use of LED light supplement technology can significantly promote the development of spinach, radish and lettuce, improve morphological indicators, and increase its growth rate and photosynthetic rate by more than 20%. It can maximize the bioaccumulation of beta tin in sugar beets and produce the highest accumulation of sugar and starch in the hair roots. The morphology of the stems and leaves of pepper and perilla can be significantly changed, and the photosynthetic rate of the plants is significantly increased. Used on flowers, it can increase the number of flower buds and blossoms, improve flower quality and prolong the flowering period. It can cause the number of stomata in marigold and sage plants to increase, and the increase in stomata means an increase in photosynthesis. LED plant light supplement light technology will be the development direction of urban facility agriculture and IT agriculture (science and technology agriculture). At present, it has become popular in the cultivation of flowers and vegetables in Japan and China.

4. What is the appropriate distance between the LED plant light and the illuminated plants?

The installation of LED plant lights must be scientific in order to effectively improve the light utilization rate of plant lights. In order to ensure the plant’s supplementary light intensity, the plant’s supplementary light should be placed as close as possible to the plant, and the distance should be set according to the power of the plant’s light. Generally, the closer the distance between the plant lamp and the plant, the higher the light utilization efficiency. Use LED plant lights to fill the light because LED heat energy is very little, it will not burn the plants, it can be irradiated at close range, the shortest distance can be 10 cm. Generally, for plant lights with power less than 8W, the irradiation distance is about 0.5 meters, and for plant lights with a power greater than 8W, the irradiation distance can be between 0.7-1 meters.

5. How long is the exposure time generally?

Depending on the growth period and growth environment of the plant, the time it takes to supplement light varies. Indoors where the light is not strong but can shine into the astigmatism of the sun, the fill-in time should be no less than 5 hours; for balconies with less than 4 hours of light (only those with light in the morning or afternoon ), the fill-in time should be no less than 4 hours; Shady areas and indoor areas without sunlight should be filled with light for no less than 10 hours. Generally, the time for supplementing light during the growth period of plants is longer and the dormancy period is shorter. On cloudy, rainy, and foggy days, the light should be supplemented for no less than 10 hours. One more thing to note is that since plants mostly photosynthesize during the day and grow at night, there is generally no need to supplement light at night.

6. How to choose the configuration ratio of red and blue lights when purchasing plant lights?

This is the most frequently asked question in buyer consultations and the most difficult to answer. Because there are so many kinds of plants, flowers are foliage, blooming, fruiting, fleshy, blooming after growing up, blooming first and then growing leaves, vegetables are leafy (such as spinach, lettuce), and For rhizomes (such as lettuce, radish), etc., it is difficult to answer exactly which plant is suitable for which configuration. But I will teach you a simple way. The ratio of red to blue light of daylight is about 6.8:1. For reference, for flowers or leafy vegetables, choose the configuration below 6.8:1, let the blue light be slightly more because Blue light is good for plant leaf growth. For flower viewers, choose more than 6.8 for supplementary light during the flowering period, let more red light, because red light is conducive to plant flowering and fruiting. From seedlings to flowering, the whole growth period needs to be supplemented. Choose 6-71.

7. How can the prices of different sellers be different for the same LED plant light?

  The performance of LED plant lights is critical to the quality of LED light-emitting diodes. Due to the uneven quality of light-emitting diode manufacturers, the quality of the red and blue lamp beads produced is also very different. Take 5mm straw hat light-emitting diodes as an example. From the price alone, there are A few cents dollars, there is about 1 USD and about 3 USD. Some sellers use a few cents dollars of lamp beads to produce plant lights, and the price of their products can be set low, but the light efficiency of such plant lights cannot guarantee the good growth of plants, and the quality is not reliable. The lamp beads of the plant lights in this shop are selected from the regular domestic manufacturers. The lamp beads have high luminous intensity, pure light color and good consistency, which guarantees the high efficiency of the LED plant lighting produced.
