Agricultural lighting has become the main driving force of the boom, which may be summarized in the following main aspects:
First, the amount of solar radiation is decreasing year by year due to the impact of the greenhouse effect, and the large-scale unpredictable production reduction caused by the impact of smog and other bad weather; Second, the rapid increase in population, the sharp reduction of arable land and clean water resources; The third is the emergence of the emerging modern urban agriculture form of facility agriculture, vertical agriculture, and plant factories; Fourth, the rapid improvement of power radiation conversion efficiency and the sharp decline in price in all possible bands of the LED semiconductor industry; Fifth, the breakthrough progress of light quality biology, from mechanism, qualitative, to quantitative and optimization of the interrelationship between environmental variables has made revolutionary progress; Sixth, the commercialization of wireless communication technology and Internet of Things intelligent control technology; Seventh, the upgrading of the solar energy industry and the drive of distributed generation policies.
LED agricultural lighting is an integrated optimization of system engineering, is a cross-industry topic, not just red light and blue chip plus lamps simple products, crops including poultry, fish growth in the continuous spectrum can be according to their own growth stage and environment to obtain the required spectral band energy for growth and development, and if only grow in two bands is unable to achieve its food quality improvement, unit area yield improvement, the most economical energy consumption and material consumption, Maximize return on investment and social benefits.
Therefore, the application of LED in the field of agricultural lighting must first carry out in-depth research and practice of light biology, but due to the existence of biodiversity problems, it must be categorized, and you can choose one or several according to your own resources and strategic direction for in-depth research and practice, and also establish a solid foundation for obtaining competitive advantages in the field of market segmentation, China is a large agricultural country, there are tens of thousands of agricultural scientific and technological personnel, universities and research institutions have accumulated a fairly deep technical foundation, It is a good choice to choose the subjects related to them to jointly research and develop LED agricultural lighting systems.
Second, there must be a considerable international perspective, the frontiers and leaders of photobiology research, and most of the best practitioners in facility agriculture, plant factories, and urban vertical farming are still concentrated in Europe and the United States, as well as in Japan and Israel. Many countries, including United Nations agencies, have many non-profit organizations and research institutions that share many research results and best practices for application.
In addition, the establishment and fitting of optimization models between environmental variables, mineralogy and light formulations (wavelength combination and ratio, control and regulation of optical irradiance, photoperiod regulation) also requires the collection, accumulation and analysis of a large amount of practical data.
