Plants also come to LED?

As a new type of fourth-generation light source, LEDs are widely used in various fields such as biology, medical care, and health. What about LED lamps used for daily lighting if they are used on plants? Is there a practical case? What is its development trend? Now I am coming from Xiaobian for everyone:

LED has become an important trend in the development of plant lighting:

It is understood that the lamp and bulb made by the principle of LED light source, the lighting itself does not have any pollution to the environment, by simulating the spectrum of the light source required for plant growth, the plant can grow every moment, and also has a effect on the stable flowering period.

The characteristics of LED light source and the existing research foundation show that LED as a plant illumination source can be widely used in plant cultivation, greenhouse light supplement, plant tissue culture, plant factories, and has many advantages such as promoting plant growth, regulating plant morphology, energy saving and environmental protection. It can not only emit monochromatic light with narrow light waves, such as red, orange, yellow, green, blue, infrared, etc., and can be arbitrarily combined according to different needs of animals and plants, and it is also a cold light source with low heat generation characteristics, which can be irradiated at close range. Plants, improving space utilization, can not only provide reasonable light environmental conditions for the growth of agricultural organisms, reduce the use of chemicals such as pesticides and hormones, ensure food safety, but also a low-energy green light source, which has broad application prospects. An important development trend of future plant illumination sources.

LED application and development in agriculture:

Artificial fill light and illumination are the most important application methods in the field of LED agriculture. According to the different needs of animal and plant development, monochromatic light of different wavelengths is combined as artificial light source, and it is flexible and adjustable with illumination intensity, illumination frequency and different time intervals. The characteristics have been promoted and applied in production. LED light source products can be designed according to different production needs and applications. It is understood that LED round head lamps, LED light source boards, LED tubes , LED flexible strips, etc. are widely used.

Xinyuan Electronics related personnel revealed that the domestic agricultural lighting fixtures and product types are basically the same as those in foreign countries, mainly including LED plant growth lamps (LED round head lamps, LED light source panels, LED tubes, LED flexible strips), LED agricultural pests. Trap lights, LED lure lights, LED livestock and poultry lighting.

Although the application of LED in the field of agricultural lighting is still in its infancy, due to its optimistic application prospects, countries have also laid out. In terms of patents, according to Yang Qichang, director of the Center for Facility Agriculture Research of the Chinese Academy of Agricultural Sciences, there are nearly 100 patents in the field of LED agricultural lighting that can be found at home and abroad, including the largest number of applications in Korea and China, followed by Japan and the United States.

LED is expected to achieve a win-win situation with agriculture:

China is a big agricultural country, and the status of agriculture is self-evident. At the same time of the development of agricultural technology, the challenges facing agricultural development are also increasing. For example, the impact of climate change on agricultural production is increasing. High-tech, low-consumption and high-efficiency modern agriculture has become an important direction of agricultural development. Development has an important strategic position and is highly valued.

It is not difficult to see that with the continuous development of modern agriculture, the demand for agricultural lighting and energy consumption are constantly expanding, and new challenges are also raised for traditional agricultural lighting technology. LED as a new generation of light source, in addition to the characteristics of environmental protection and energy saving, compared with the artificial light source such as fluorescent lamp or high pressure sodium lamp currently used in agriculture, it has the advantages of adjustable light quantity, adjustable light quality, low cooling load and the possibility of increasing the cultivation amount per unit area. It is a very suitable artificial light source for closed agricultural production environments, such as plant tissue culture rooms. At the same time, it has great application potential in breeding and microalgae cultivation.

The person in charge of Xinyuan Electronics believes that the application of LED will bring a brand-new "revolution" to agriculture. Whether it is from the perspective of promoting the development of modern agriculture or achieving energy conservation and environmental protection, LED is very important for agriculture. The significance, and the status and development needs of agriculture also provide opportunities for LED development.
