LED grow light application prospects

According to the Chinese Academy of Agricultural Sciences Institute of Environment and Sustainable Development Research Professor Liu arts presentation, as this plant is similar to the way plants grow, through the facilities within a high-precision environmental control, crop anniversary of continuous production and efficient agriculture system, is a computer for crop growth process temperature, humidity, light, CO2 concentrations and nutrient solution automatic control and other environmental elements, without or little affected by the new mode of production constraints in natural conditions. And it is considered an important way to the 21st century to solve the population, resources and environmental issues, but also the future of an important means to achieve food self-sufficiency during the exploration aerospace engineering, moon and other planets.

Photosynthesis is the basis of plant production, efficient photosynthesis must provide appropriate lighting conditions (light intensity, light quality, and photoperiod) and complementary growth factor (nutrient supply, temperature, CO2 concentration, etc.). LED light source for the earliest cultivation of plants in Japan, after the United States NASA space base will be LED Closed for life support systems lighting. The mid-1990s, NASA began screening and development of LED light source for plant cultivation, developed many lighting system specifically for the space shuttle and the international space station use. These results for the LED light source used in various production areas Horticulture laid the biological basis of plant light quality.

LED semiconductor light source appears not only provides ideal light source controlled environment for plant cultivation, but also for the study of plant biology light quality provides a test tool. LED light sources can not match traditional photovoltaic advantage is the ideal light source plant factory environment regulation. Its advantages mainly in: 1) LED can be modulated spectrum of plant growth and development needs, on-demand light, high biological luminous efficiency; 2) LED is cold light source, close to the plant irradiation can improve space utilization; 3) LED to DC controllable, can accurately regulated light intensity, light quality and light cycle, suitable for industrial production; 4) Energy saving, environmental protection, long life, small size, light weight; 5) LED light source device diversity (light board, lights, lamps and light bulbs), suitable Horticultural applications in various fields. These advantages make LED light source in the artificial light plant factory light environment control and plant factories sunlight artificial light has a wide range of applications. LED light source plant factory plant factory is the direction of development, in line with modern agricultural production efficiency, high yield, high quality, ecological and safety of the general requirements, energy-saving effect is obvious, popularization and application prospects.
