In July, Taga City, Miyagi Prefecture, in the earthquake-stricken area of Japan’s “311” earthquake, showed the media an artificial light plant factory using LED lighting. This is currently the world’s largest plant factory that uses LED lighting. 10,000 lettuce and so on.

For a time, LED plant lighting has become the hottest topic in the industry right now. Not only are major overseas lighting manufacturers such as GE, Siemens, and Philips investing heavily in plant lighting, but domestic lighting companies have joined this trend without exception.

However, the general manager of Jiangmen Honglin Lighting Technology Co., Ltd. said that at present, LED plant lighting is just a "virtual fire". Under the constraints of the lack of comprehensive talents and high cost investment, LED plant lighting has not yet been industrialized, and it can only Aimed at the high-end market.

　　 Investors are optimistic about the acceleration of market growth

From the global market, the sales market of LED plant lights is mainly concentrated in Japan, South Korea, the United States, Europe and other countries and regions with fewer agricultural personnel. At present, there are already many LED plant factories abroad, which can realize the mass production of plants.

　In Japan this year, about 40% of vegetables are produced in automated factories such as LED cultivation, and the products are mainly supplied to mid-to-high-end supermarkets and stores.

　According to an industry survey in the global field, the global output value of LED plant grow lights has shown rapid growth since 2013. It is expected to exceed 35 million U.S. dollars in 2014 and is expected to reach 300 million U.S. dollars in 2017. Some large international companies have increased their innovation investment in LED plant factories.

is not only a foreign lighting company, but also a "vegetative wind" in the domestic lighting market.

　　 The author has learned that the current LED plant lighting industry in China is growing rapidly with a market growth rate of 20%, and more than 50% of LED lighting companies are doing LED plant lighting related research and development.

In the past 10 years, the area of facility horticulture in China has developed rapidly, and the light environment control technology for plant growth has attracted attention. The development of greenhouse planting and flower industry in Shandong, Jiangsu, Zhejiang, Henan and other areas has been quite mature, so LED plant lights have great market potential.

　　 Compared with fluorescent lamps, the use of LED lighting can not only save 40% of the electricity, but also increase the yield by adjusting the wavelength of the light.

　　Plants can perform photosynthesis for 16 hours a day, but the natural light time is very limited, which makes plants grow slowly. If LED lights are used to continuously add light to plants and use LED light instead of natural light, the vegetable maturity period can be shortened by one-third at the fastest, and yield can be increased. The original 15-day-ripe vegetables can be harvested in just 5 days. A typical example of using LED light to promote plant growth.

The plant factory seedling industry alone provides a huge consumer market for LED light sources. According to the calculations of the Nanjing Agricultural University research group, the export of seedlings alone reaches nearly 10 billion plants every year, and the domestic annual consumption is even greater. If LEDs are used to replace traditional light sources in plant factory seedlings, the total one-time market size will reach 200 billion yuan.
