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 traditional agricultural field, such as fluorescent lamps or high-pressure sodium lamps and other artificial light sources, the light quantity can be adjusted, the light quality can be adjusted, the cooling load is low, and the cultivation per unit area is allowed to be improved. Has a huge application value. It is foreseeable that the application of LED will bring more innovation to agriculture.
With the continuous development of modern agriculture, the demand for agricultural lighting is expanding, and the resulting increase in power consumption has increased. This not only challenges traditional agricultural lighting technology, but also provides a good opportunity for the development and application of new agricultural lighting. Yan Jun, deputy secretary-general of the National Semiconductor Lighting Engineering R&D and Industry Alliance, said.
LED agricultural lighting is a niche market. In the view of Dr. Junjun, the development of LED lighting technology has been more mature in the past two years, and it has gradually begun to be introduced into agricultural lighting applications. A plant factory that uses LED light sources and environmental control features has become a niche market that major manufacturers are eager to cut into in recent years. In such a market, companies choose a small product or service area, concentrate on entering and becoming a leader, and at the same time establish various barriers, which is expected to form a lasting competitive advantage.
Qi Jun believes that LED light source has great market potential in the agricultural field. The first is based on the huge demand for agricultural lighting. Taking greenhouse light supplement as an example, the light-filling facility is a basic essential component of modern glass greenhouses. At present, China has a glass greenhouse of 35,000 hectares, while the global glass greenhouse has a total area of ​​49,000. Hectare.
In fact, the combination of LED lighting and modern agriculture can bring multiple benefits. It can shorten the harvest period of crops, plants or flowers, and with proper environmental control, it can not only prevent pests, but also avoid pesticides or reduce pesticide use. For food safety, it also increases the added value of agricultural products.
Forward-looking technology is aimed at the future investment. In the view of Qi Jun, China's LED industry has initially formed a relatively complete industrial chain. Among the enterprises that produce LED agricultural lighting, the small and medium-sized enterprises that produce low-end products account for the majority. Lack of core independent intellectual property rights and systematic research, there are very few leading enterprise groups that can participate in international competition. LED agricultural lighting products are not uniform, there is no same standard, and the scale of enterprises is still small. In such a market structure, companies that master core independent intellectual property rights are even more valuable.
From a policy perspective, the state's emphasis on LED plant production applications has gradually increased. For example, during the 11th Five-Year Plan period, a project was set up through the 863 Program. During the 12th Five-Year Plan period, several LED agricultural research projects were also supported.
A major factor in the current idle LED light source agricultural lighting application is cost. Yan Jun said. Despite this, the army believes that with reference to the annual decline in the price of LED light sources in recent years, with the increase in technology maturity and the expansion of the application scale, and taking into account the gradual overweight of government support and subsidies in research and development and sales, the cost will be higher. The closer to the traditional light source. Moreover, since the LED light source has obvious advantages over the traditional light source, it is still a very forward-looking technology in China, and the growth space for application promotion is huge, and it is an investment that conforms to the future industry trend.
