Did you know that LED grow lights are not ordinary lighting fixtures!

More and more people attach importance to energy-saving and environmentally friendly products, coupled with the government's vigorous admiration. LED is known as the fourth-generation "light" era because of its energy-saving, environmentally friendly, and long-life characteristics. It is recognized and accepted by more and more people. The market is developing very rapidly. I didn't know LED (luminous) 10 years ago. What is a diode) is normal. After 10 years, I don’t know that LED means that I can’t keep up with the times. LEDs are widely used. It can be said that LEDs can be used in places where light is needed. They can be roughly divided into LED home lighting, LED commercial lighting, LED advertising lighting, LED agricultural lighting...

LED agricultural lighting includes plants, animals, and algae. Now the most application is still on plants, covering the cultivation, growth, flowering, and fruiting stages of plants. As the available land becomes less polluted and less resources, it is becoming more common to grow vegetables and flowers indoors, and they can be planted out of season. Nowadays, the development of science and technology has transformed modern high-tech agriculture from relying on the sky in the past, and this breakthrough is the successful application of LEDs in current agriculture.

Currently used in plants are mainly high-pressure sodium lamps and metal halide lamps, most of which are hundreds of watts or more than kilowatts. These light sources contain many unnecessary wavelengths, their biological light efficiency is very low, and the energy consumption is large, but they are absorbed by plants only ten percent of them, and they emit harmful gases during use. LED has the outstanding advantages of narrow wavelength, pure light quality, high luminous efficiency, rich wavelength types, convenient spectral energy modulation, low heat generation, small size, long life, etc. It is convenient to concentrate the wavelengths required by plants to implement balanced close-range irradiation. For plant production, intensive plant production with high efficiency, low heat load and compact space can be realized, and the use of plant hormones or other chemicals can be reduced; for the physical control of agricultural pests, LED light sources with specific wavelengths can be used to attract It also kills pests, reduces the amount of pesticide application, and achieves safe and green production; it can provide effective photosynthesis for plants. Can reach more than 90% absorption. As a new type of lighting source that can be used in agriculture, LED is increasingly popular.

At present, most manufacturers of LED Grow Lights are LED household and commercial lighting manufacturers, thinking that it is a combination of red and blue lighting. In fact, plant lighting is another subject research. "Light, temperature, humidity, carbon dioxide, air" are the main environmental conditions required for plant growth and development, and "light" is the most important of these factors. Plants have different requirements for spectroscopy at different stages. This is also an important research project for researchers and a difficult problem for enterprises to solve. From the appearance point of view, the most common led grow light are panel type, round type, tube, followed by spotlights, bulbs, strips... Most of the existing commercial household lighting shells can be replaced with red blue. , But this is not a plant light. LED Full Spectrum Light need to have some special functions. It is necessary to solve the problem of plant growth, increase production, shorten the growth cycle, and extend the flower cycle. From this point of view, it is completely different from household and commercial lighting. Therefore, LED Flower Light are not ordinary The lighting fixtures are equipped with "recipes" according to the needs of plants.

Plant growth is achieved by storing organic matter through photosynthesis. Therefore, the intensity of light has a great influence on the growth and development of plants, and it directly affects the strength of plant photosynthesis. From the classification of plants, it can be divided into negative plants and positive plants. Negative plants need 2-6 hours of light a day, and the light should be weak, and positive plants need 12-16 hours a day, and the light intensity is relatively strong.

The intensity of light given depends on the compensation point of each plant And the saturation point, because the compensation point and saturation point are different for each plant. The light intensity cannot be lower than the compensation point and cannot exceed the saturation point. When the light intensity exceeds the compensation point, the plants will not grow and the leaves will turn yellow. When the light intensity exceeds the saturation point, the light intensity increases again, and the photosynthesis intensity does not increase. When the light intensity is too strong, it will destroy the protoplasm, cause the decomposition of chlorophyll, or cause the cells to lose too much water and close the stomata, causing photosynthesis to weaken or even stop. When the light intensity is weak, the organic matter produced by photosynthesis of the plant is less than the consumption of respiration, and the plant will stop growing. Only when the light intensity can meet the requirements of photosynthesis, plants can grow and develop normally.

For example, peppers and tomatoes are positive plants, and the lowest compensation point must reach 2000 LUX to have an effect on their growth and development. Below this illuminance value, they will not grow. Therefore, when choosing an LED plant grow light, it is best to understand its type, whether it is a female or a positive plant, and what is its compensation point, so that you can choose a suitable LED grow lights for plants.
