In the past ten years, China's facility agriculture has developed rapidly, and the light environment control lighting technology for crop growth has attracted attention. "Application research of semiconductor lighting source in plants" is one of the national "863" key support projects. After the launch of this project, many lighting companies are eager to try and try to "early adopt" agricultural lighting. There are a number of companies on the right track. Wuxi Huazhao Optoelectronics Technology Co., Ltd., Guangdong Luai Biotechnology Co., Ltd., Xiamen Guangyi Electronics Co., Ltd., and Shanghai Heming Lighting Appliance Co., Ltd. are undoubtedly the best among them. However, although the agricultural lighting market is huge, there are still many problems at present, and the lighting companies involved are “and cherished”.
Wuxi Huazhaohao Optoelectronics Technology Co., Ltd.
Plant lighting: To understand LEDs, also to understand plant characteristics
Hua Zhaojun currently maintains good cooperation with the Institute of Science and Technology of China: signed a strategic cooperation agreement with the Institute of Semiconductors of the Chinese Academy of Sciences on the application of semiconductor high-power light sources in agricultural applications, and participated in the research and industrial organization of semiconductor lighting engineering. Formulation of technical specifications for LED dot matrix plant panel lights. Chang Zhaoyan, general manager of Huazhaoyu introduced: Hua Zhaojun's research in agricultural lighting mainly focuses on scientific research, demonstration projects and plant tissue culture, and the export is developing.
Chang Baoyan believes that: agricultural lighting is not simply the development and research of light sources and lamps, but also must combine the characteristics of agriculture, including light, electricity, control, structure, biology, physics, environment and other multidisciplinary, the threshold is very high, domestic manufacturers still have There is a long way to go; at present, the country is still in the demonstration stage of the project, and the market is still very immature; the country's support for agricultural lighting is extremely incompatible with the huge application potential of LED agriculture.
For many lighting companies trying to get involved in the field of agricultural lighting, Chang Baoyan cautiously put forward his own views: from the plant point of view, the diversity of plants and the difference in light demand at different growth stages determine the LED agricultural lighting products from Spectral settings, lamp types, intelligent control, etc. will be highly targeted, in addition to solving the problem of the lamp itself, but also understand the corresponding plant characteristics.
Before cutting into the field of agricultural lighting, everything is ready, and you can naturally see the vast space of the agricultural lighting market. "The characteristics of LED light source itself are destined to become the mainstream products of agricultural lighting. There is great potential for plant supplementation, insecticide, insecticide, sterilization, etc. Our company will continue to strengthen product research and development, and strengthen research institutes at home and abroad. In-depth cooperation to provide system solutions for agricultural lighting." Chang Baoyan is full of confidence.
Guangdong Green Love Biotechnology Co., Ltd.
LED lights used in vertical growth plant factories may not be good
Guangdong Green Love Biotechnology Co., Ltd. mainly tends to develop plant factories. General Manager Wang Xianlong said that in the past, the main use of energy-saving lamps and metal halide lamps for plant lighting, with the development of plant factories accelerated, vertical planting situation is good, so Green Love is focused on the development of plant LED lighting. Now, Green Love Bio Products mainly has three categories: panel lights, downlights, and lamps. By the end of this year, Green Love will launch 15-20 new products.
Wang Xianlong introduced that there are two main sources of technology for green love organisms: foreign cooperative institutions include the famous agricultural university Chiba University, the University of Nottingham in the United Kingdom, and the University of Ontario in Canada; the domestic agricultural academy, the South China Agricultural University, and the Chinese Academy of Sciences. The South China Botanical Garden of the Chinese Academy of Sciences has deep exchanges and cooperation with each other.
The plant factory is ready, and Wang Xianlong has sensiblely analyzed the application of LED lights in plant factories. “The metal sodium lamps used in agricultural lighting, or energy-saving lamps, are also used well in greenhouses; LED lamps are used in higher-form vertical growth plant factories, which are complicated and not necessarily completely good because our company Pay attention to the economics of light efficiency. For example, when I went to the South China Botanical Garden of the Chinese Academy of Sciences, the effect of LED agricultural lamps used in tissue culture was not obvious, and it was not obvious in planting. We still have many problems in research and development. Wang Xianlong also faces the most important problem facing plant lighting at present: no large-scale planting is verified in the laboratory, and there is no universal production guidance. As a result, Green Love has established a 1,000-square-foot LED plant in Jiangmen. The infrastructure has been completed in May and will be officially opened in July. “This will be the largest fully enclosed LED artificial light plant in South China. It will not only provide a large-scale research base for scientific research institutes, but also provide a large amount of data to lighting companies to make more precise and practical agriculture. Use the light."
For the future planning of Green Love, Wang Xianlong is very cautious, because China's agricultural lighting has not yet developed to a certain stage. Unlike foreign related companies, especially Japanese companies, the Japanese government has raised the LED plant factory into a strategic emerging industry. Government subsidies can be obtained on a large scale. “Green Love is a private enterprise. Under this circumstance, we cannot wait for the support of national policies. We must do our own efforts first. Our goal is to fully market and provide safe, nutritious and high-quality vegetables and fruits to the society. There are no pesticide residues, nitrites exceeding the standard, and heavy metals exceeding the standard. Through the operation of the plant factory, through cooperation with various parties, various plant lamps have been developed to meet the increasingly demanding agricultural production, especially urban agricultural production. At the same time, Wang Xianlong is also full of confidence: "Foreign developed countries are also starting small in LED plant lighting. We hope that the whole society will work together and cooperate with innovation to overtake the car and catch up with the world-class level. Through the multi-party cooperation to obtain the most accurate The data to guide the plant lights in the end, in the plant Xiyin, Xiyang, neutral or seedling period, growth period, flowering and fruiting period can be developed in different periods of lighting. Agricultural lighting vision is good, especially the need for the whole society common norms promote."
Jiangmen Plant Factory
The Jiangmen Plant Factory Project, which has already started, is currently undergoing intense design and plant renovation, and will be officially operational in July. The factory is divided into four production parts: vegetable and fruit hydroponic experimental production area, vegetable and fruit aerosol cultivation experimental production area, Chinese herbal medicine substrate cultivation experimental production area, tissue culture research production area, plus a biological research room, a nursery room, a logistics, Production preparation area and nutrient solution, water room. The factory will introduce advanced Japanese and Korean equipment. In the second half of the year, we will provide safe, nutritious and high-quality vegetables, strawberries, etc. to the society and the market, and Chinese herbal medicines without pesticide residues will be available next year.
Xiamen Guangsheng Electronics Co., Ltd.
LED plant fill light requires the establishment of product standardization system
The "Application Research of Semiconductor Lighting Sources in Plants" project also attracted the optical electronics. Under the dual needs of the agricultural industrial environment and the political and economic environment, Guangxu has already started the upgrading of the energy-saving and environmental protection industrial chain in the field of agricultural lighting as early as 2012.
According to reports, the professional R&D team of Guanghao Electronics has developed plants, animals and intelligent lighting systems. It has successively cooperated with the Chinese Academy of Sciences, the Academy of Agricultural Sciences, the Hong Kong Academy of Sciences, the China Semiconductor Lighting Research Laboratory, Fujian Agriculture and Forestry University and the Subtropical Plant Research Institute. Established a long-term cooperative relationship and continuously turned the results into guiding actual production. At present, the products have been promoted to Hong Kong, Macao and Taiwan as well as overseas markets.
In traditional agricultural production, the use of ordinary electric light sources to supplement light and the application of different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps or colored plastic films, to change the light environment to regulate the growth and development of plants in the facility cultivation environment. However, these measures have different degrees of problems. For example, the lack of analysis of specific spectral components leads to impure optical quality processing, inconsistent light intensity, close to or even lower than the plant's light compensation point, and low energy efficiency of the illumination source. A large number of application studies of LEDs in plant facility cultivation environments have shown that LEDs can solve these problems and are particularly suitable for use in artificial light-controlled plant facility cultivation environments.
In areas where agriculture is relatively developed, the development of greenhouse cultivation and flower industry is quite mature. The Ministry of Agriculture has set up a special technical department, trained a large number of agronomic technicians, and invested relatively large human and physical resources; correspondingly, LED Plant light-filling products have a large market space and have a large-scale development trend; however, they are limited by the quality of suppliers, lack of light formula research data support, price acceptance, etc. LED plant fill light requires product standardization. The establishment of the system, as well as the vigorous promotion of the market.
Optoelectronics confidently said that in the long run, it will definitely have a competitive advantage with the decline in LED costs. On the other hand, research on technologies related to agricultural lighting, such as light quality, light intensity and photoperiod, and the further disclosure of resources and information from a small number of companies and institutions that are ahead of the curve will also accelerate LED as agricultural lighting. The popularity of light sources is large.
Shanghai Heming Lighting Appliance Co., Ltd.
Future agricultural lighting development needs to be intelligent
From Taiwan to the mainland, Zhang Zhendong, general manager of Shanghai Heming Lighting Appliance Co., Ltd. has been committed to technology research and development in the field of agricultural lighting. “Agricultural lighting contributes a lot to the agricultural sector: plant light can be dewormed if it is more precise, and eggs can be killed in certain spectral environments; and plant lights can generate heat due to their own heat, thus reducing the plants in the greenhouse. The planting humidity, plant mildew can also be reduced to a certain extent, and the photosynthesis effect of plant light to promote plant growth is better, thus reducing water and soil pollution, and ensuring people get healthy green. food."
It is precisely because of this concept that Heming Lighting pays more attention to technological innovations, including plant growth lamps and smart pot plants. “Shanghai Environmental Protection Supervision Station has done testing, the highest rate of formaldehyde removal is 96%, and the negative ion concentration can reach 20,000/cm3.” Zhang Zhendong is quite proud.
When entering the mainland market, Heming Lighting provided free plant lighting products to Beijing Agricultural Academy, Tianjin Academy of Agricultural Sciences and some agricultural departments of Huludao. Among them, Heming Lighting's plant growth lamps were in Gongyingzi Township, Chaoyang City, Liaoning Province. The greenhouse application has been applied to the greenhouse, and the local greenhouse vegetable production has increased by about 20%. “This news was highlighted in the news headline on October 16, 2010. Now more than half of the domestic agricultural lighting industry uses it. It is the lighting products of Heming Lighting." Zhang Zhendong said.
For the development trend of agricultural lighting in the future, Zhang Zhendong believes that it should be divided into two categories: “One is rural and the other is urban. The key is how to make the future agricultural lighting as intelligent as possible. Because farmers are not experts, he will not apply it scientifically. These products, so we hope that agricultural lighting can connect with the Internet of Things as much as possible, so that its use method is as accurate and practical as possible, and it can use intelligent agricultural lighting to reduce the false judgment of plant illumination demand according to the difference of solar light changes. To improve the efficiency of light and the service life of lamps." Therefore, the use of Heming Lighting in rural areas is also classified. "Different from rice seedlings and vegetable seedlings, we are constantly improving the lighting needs of different agricultural crops. More suitable light source, we hope that our plant lighting technology can help farmers as much as possible, and correspondingly can open the market of agricultural lighting."
