First, the status of plant lighting industry
1. Regional distribution of plant lighting enterprises in China
At present, there are more than 300 enterprises engaged in plant lighting in China, which is nearly double the statistical data of 2015.From the perspective of China's plant lighting industry as a whole, the Pearl River Delta region's plant lighting industry has been in the main position, accounting for more than 50%;The Yangtze River Delta region is still an important production area, accounting for 30%;Other regions accounted for 18 per cent.
Current plant lighting fixtures can be divided into two camps:
(1) Traditional plant lighting fixtures such as HPS, energy-saving fluorescent lamps, HID
(2) Emerging LED plant lighting fixtures
The cost of traditional plant lighting is relatively low, and it still occupies a certain proportion in the plant lighting industry.However, from the analysis of export data of Chinese plant lighting lamps, the export data of traditional plant lighting lamps has been in a negative growth trend since 2015, and the market share is gradually shrinking.According to statistics, China's traditional type of plant lamp enterprises mainly distributed in the Yangtze River Delta, pearl River Delta and bohai Rim area.The Yangtze River Delta region accounts for 53%, the Pearl River Delta and the Bohai Rim region account for 24% and 22% respectively.LED plant lighting enterprises mainly distributed in the Pearl River Delta region accounted for 62%, the Yangtze River Delta region 20%, the Bohai Rim region for 12%.
, the regional distribution of global plant lamp manufacturers
At present, in addition to the mainland region of China, the most mature areas of the global plant light market are: North America, Europe and Japan. According to the data statistics, the well-known manufacturers in the United States and Japan respectively account for 37% and 23%, which is the most active area of the plant light application market.
3. The proportion of LED patents in the field of plant lighting application by region
By the end of 2017, in terms of the proportion of patents in the field of plant lighting, Japan has 180, accounting for 27.1%, ranking first.China was next with 141 patent applications, or 21%.These data show that the most active innovation of LED plant lighting is in Asia. Japan has accumulated a lot of technical experience in the application of plant factories for many years. Although China lags behind in development, it has a strong innovation ability and it is believed that it will soon surpass Japan and take the lead in the world.
4. Analysis of domestic LED plant lighting industry
From the current situation of enterprises entering the FIELD of LED plant lighting, there are two main characteristics:
First, there are a large number of LED application enterprises in China, but LED plant lighting is an emerging field. After 2005, relevant institutions in China began to conduct research in this field, so there are not many enterprises and institutions entering the FIELD of LED plant lighting. At present, no enterprise has obvious advantages in this field.
Second, most enterprise of LED lighting plants are still on the sidelines or try the water phase, there are few companies in the plant lighting products as the main products of the enterprise, but promotion of small-scale trial production and do some demonstration projects, nor in the core technology and downstream sales channels construction a large number of investment, the development direction of product and market planning also not too clear.
Second, LED plant lighting technology status and development trend
1, LED plant lighting spectrum
The spectrum of plant lighting is complex and diversified. Different plants have different growth cycles and even in different growth environments, the spectrum required is quite different.To meet these differentiated needs, the following solutions are available in the industry:
1.1 A variety of monochromatic light combination schemes represented by Osram and Philips are mainly based on the spectrum of 450nm and 660nm, which are the most effective peaks for plant photosynthesis, and the 730nm band for plant flowering induction, plus a little green light at 525nm and uv band below 380nm.These spectra are combined according to the different needs of the plant to produce the most suitable spectrum.
1.2 SUNLIKE (imitation of solar light spectrum) represented by Seoul Semiconductor and Samsung, which is called full spectrum by the industry to achieve full coverage of plant demand spectrum.Many experts in the industry agree with this approach very much. This kind of spectrum may not be the most efficient, but it must be error-free, and the cost is much lower than the monochromatic light combination scheme, which is easy to be accepted by the market.
1.3 Take advantage of the combination of scheme 1 and Scheme 2. At present, several companies in the industry have adopted this combination scheme, which is mainly full-spectrum white light, plus 660nm red light to improve the spectral effectiveness.This scheme is more economic and practical, in the future a period of time should have a larger market.
With the improvement of intelligent control technology and the application of the Internet of Things, road lighting and home lighting have begun to develop towards intelligent control. The complex demand of plant lighting for real-time control of light quality and light quantity is more intense.So a variety of monochromatic spectrum and intelligent control system to achieve time control, light control, according to the growth of the state of the plant timely adjustment of light quality and light output is bound to become the main trend of future plant lighting technology development.
