LED agricultural lighting starts from the domestic enterprises, and they want to share a piece of cake.

LED agricultural lighting tends to specialize

The application of LED in modern agriculture has unparalleled advantages and practical applicability. Not only has the scope of application been expanded, but the classification has become more specialized and refined.

Compared with traditional electric light sources, LED has unparalleled advantages and practical applicability in modern agriculture. "With the continuous progress in the research on the spectrum required for the growth of plants and animals, and the significant decline in the cost of LED production, the domestic LED agricultural lighting industry has developed rapidly in the past two years, driven by demonstration applications in various regions." Junsheng Investment Management Zhang said that the investment director of the company.

Not only has the scope of application been expanded, but the classification has become more specialized and refined. Song Changbin, a researcher at the Institute of Semiconductors of the Chinese Academy of Sciences, said that the application of LED in agriculture, in addition to the well-known "plant factory", also includes a variety of categories such as aquatic products, livestock, flowers and herbs. Although the general direction is to increase production and income, but the application of different categories involves different disciplines, it is necessary for professionals in multiple fields to work together.

According to Song Changbin, in his familiar aquatic industry, research results have been industrialized, and many domestic fishery companies have already gained profits in cooperation with the Chinese Academy of Sciences.

In Zhang Wei's view, the application of LED lighting in the agricultural field is divided into two levels. The first level is the most basic energy-saving property using LED lighting. Taking livestock and poultry farming as an example, artificial lighting is one of the important means of intensive environmental control of livestock and poultry houses. The replacement of long-term incandescent lamps and fluorescent lamps with LED light sources can greatly reduce energy consumption and reduce costs. The second level is to achieve intelligent lighting with LEDs by selecting wavelengths and adjusting power. Light quality control for the physiological needs of livestock and poultry can greatly improve production efficiency.

Plant lighting "Qian Jing" is vast

The global LED plant growth lamp output has started to show rapid growth since 2013, from 10 million US dollars to around 35 million US dollars in 2014, and is expected to reach 300 million US dollars in 2017.

Among the many application categories, the development of plant lighting has the greatest potential. "LED as a plant illumination source can be widely used in many fields such as facility cultivation, tissue culture, plant factories, etc. It has many advantages in promoting plant growth, regulating plant morphology, and energy conservation and environmental protection." Zhang Wei said, "Where, the plant factory set Modern biotechnology, information technology, artificial environment control and other high-tech technologies, not only yield more than land cultivation, but also can be produced on non-cultivable land such as Gobi, desert, island, water surface and even city buildings. It is also considered to be an effective technical means to solve problems such as population, resources and environment in the future."

In fact, in Japan, South Korea, the United States, Europe and other countries and regions with less agricultural personnel, LED plant lighting is much more popular than in China, and the LED plant growth lamp sales market is also concentrated in these areas. The data shows that the global LED plant growth lamp output has begun to show rapid growth since 2013, from 10 million US dollars to around 35 million US dollars in 2014, and 2017 is expected to reach 300 million US dollars.

Although starting late, LED plant lighting is becoming more and more widely known in the country. As an agricultural high-tech enterprise under the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences, Beijing Zhongda Yida Facilities Horticulture Technology Co., Ltd. is the earliest research and promotion of key technologies in plant factories, LED plant light sources, home gardening, etc. Development and planning and design of agricultural parks. Wei Zihan, the company's marketing director, said that at present, domestic plant factories have moved from local government demonstration projects to more and more high-end residential areas, and the operation of the project itself has begun to shift from simple demonstration and viewing to the pursuit of balance and even profit.

Domestic companies are ready to go

With the rapid development of China's photovoltaic industry, the decline in photovoltaic power generation costs makes it possible for LED plant factories to make profits. If a suitable profit model is found, the LED plant factory can develop rapidly in China.

According to Wei Zihan, after years of research and accumulation, the LED lighting products promoted by the company are not only 60%~80% more energy efficient than ordinary fluorescent lamps, but also in the special formula of light source quality, in addition to red light and blue light, Different proportions of green light, yellow light and far infrared light, wherein green light protects the human eye, yellow light can increase the value of the object itself, such as chlorophyll and carotene to improve the nutritional value of the plant itself, far infrared light can Increase plant yield by 10% to 20%.

“We will provide different technical solutions for different users and plants.” Wei Zihan said, “But technology is only one part of it. The operation and maintenance of the whole project is the most important thing at present.”

Wei Zihan admits that the development of LED plant lighting in China is at a critical stage from demonstration to profitability, including the National Agricultural Science and Technology Exhibition Park of the Chinese Academy of Agricultural Sciences, which is responsible for the operation and management of the company. Many LED plant factories in China are in the process. Actively explore the main profit model through various methods such as membership supply and cooperation with high-end restaurants. "Once a road has gone through, it will go smoothly, and the LED plant factory will develop rapidly in China," he said.

With the rapid development of China's photovoltaic industry, the decline in the cost of photovoltaic power generation has also made it possible for LED plant factories to make profits. "According to our calculations, the cost of organic vegetables produced by photovoltaic-powered LED plant factories is only about 20% higher than that of ordinary organic vegetables on the market." Zhao Ning, technical director of Dynamic Chemicals, said, "and further development of future technologies." The cost reduction is only a matter of time."

According to Zhao Ning, with the support of the local government, the smart agricultural demonstration park built by the company using LED, photovoltaic and other technologies is about to be put into operation. It is estimated that the park will cover an area of ​​10,000 mu, which will not only bring significant The demonstration effect can create considerable economic benefits.

"The domestic market has huge room for development, but it will take some time to cultivate." Zhao Ning believes that "currently is a good time to enter the overseas market." It is reported that the company launched a cost-effective LED plant growth promotion lamp for the European and American markets. It will be available next month. "The sales are not good." Zhao Ning said with a smile.

“Compared with other companies, companies such as Zhongda Yida and Dynamics Chemical Co., Ltd. are also engaged in production and sales in the middle chain of the industry chain, and they also have advantages in plant factories that operate downstream applications. This is related to photovoltaic manufacturing enterprises. It is also a reason to build and operate a power station. Zhang Wei agrees with this model.
