LED technology will force the field of agricultural lighting

LED intelligent lighting technology will be launched in the field of agricultural lighting. On the 19th, the Guangdong Modern Agriculture (Plant Factory) Application Demonstration Base was formally established at the Guangdong Semiconductor Joint Innovation Center in Foshan High-tech Zone. Many agricultural experts and scholars and LED production and application companies attended the ceremony and jointly explored a new model of modern agricultural lighting development at the second Agricultural Lighting Development Forum held on the same day.

Industrialization and intelligence combined

On the 3rd floor of Building A8, the new light source industrial base in Guangdong Province, an office of 150 square meters was transformed into a micro-plant factory with a complete intelligent system. “The base adopts a 4-layer three-dimensional cultivation mode. Currently, the planting crops are mainly leafy vegetables, and the actual planting area is 126 square meters.” The relevant person in charge of the plant factory said that the system is through LED lighting technology, intelligent control technology and no The combination of soil cultivation techniques realizes the integration and intelligence of the environment and water and fertilizer management.

"In addition to the use of computers to automatically control and adjust the environmental elements of the crop growth process, it is also necessary to supplement the red and blue LED agricultural lighting suitable for different types of plant growth." The above-mentioned person in charge said that through the environment and lighting control of the facility So that plant production is not affected by environmental factors such as geography and climate, which will lay the foundation for the realization of streamlined continuous production in the future.

In fact, as one of the pillar industries of Foshan High-tech Zone, the LED intelligent lighting industry is not accidental in the field of agricultural lighting. "With the continuous improvement of LED technology and the expansion of popularization, the application cost of artificial artificial radiation source based on its technology has been further reduced." Yan Shirong, director of the Guangdong Semiconductor Lighting Industry Joint Innovation Center, said that competition in the LED industry is intensifying. Under the background, the birth of a new industrial form of “plant factory” has also found a way for traditional LED companies to transform and upgrade.

“In the case of a plant factory of 10,000 square meters, about 18,000 LED tubes can be used.” In addition, modern technology has been used to drive the transformation and upgrading of traditional industries, and to further accelerate the industrialization of traditional agricultural methods. The footsteps.

Realizing industrialization is the development goal

As early as 2013, Zhou Zhandeng, general manager of Foshan Zhongde Optoelectronic Special Lighting Co., Ltd. began to experiment in the field of agricultural lighting. "LED is still in its infancy in the field of agricultural lighting. The problem that needs to be solved now is to analyze the wavelength sensitivity of different plants to light, and to develop corresponding artificial light sources according to the varieties to promote the growth of plants." Zhou Zhaopeng said.

In this regard, Yan Shirong expressed his approval. “The spectral environment required for each plant is different. Excessive illumination can lead to longer plant growth cycles. Therefore, it is necessary to continue to explore the growth patterns of different types of plants.”

For the emerging industry of plant LED lights, price is still a very important part. "As the LED industry was just emerging, an LED street light would have to be sold for 20,000 yuan. After five or six years of development, the price of an LED street lamp is now around 1,000 yuan." Wu Shirong said, this also shows that any new one The industry has a process of growth. As long as two to three years of cultivation, development and large-scale production, the cost of plant LED lights will be well resolved.

In view of the relatively high cost of planting ordinary vegetables, Qi Shirong can develop and produce some high value-added products at this stage. Taking asparagus as an example, the yield per mu can reach 15,000 yuan. It is easier to be accepted by the market through the commercial model of LED plant factory to produce such high value-added agricultural products.

“The next phase of the development goal is to build the plant factory into a modern agricultural production base integrating R&D and cross-border e-commerce, making it the largest plant factory trading center in Guangdong and even the whole country.” Qi Shirong said, at the same time It is necessary to fully mobilize various resources such as the government, enterprises, and research institutes, and work together to achieve the industrialization goal of plant factories through the innovation center platform.

It is reported that the next innovation center will join the provincial agricultural bureau, science and technology department and other departments to promote the integration of production, education and research of LED plant illumination system through the platform of Guangdong Modern Agriculture (plant factory) application demonstration base, and continuously innovate and improve the commercial operation of plant factories. mode.
