LED Intelligent Lighting Of Lamps In The Agricultural Application
May 11, 2016

Plants use sunlight for photosynthesis, and visible light absorption spectra in the 380~760 NM, which incorporates peak wavelength 610~720 nm for red-orange light and 400~510 nm blue-violet. And continuous rainy weather affect the growth of plants is to crops, research and development of intelligent light control will solve this problem, development was not affected by the weather, farming technology will be a new direction.
By controlling front-end (smart phone, tablet or controlled platform), sensors (Sensor), fieldbus (Fieldbus) and plant growth regulating system composed of LED lights as shown in Figure 1. Smart phones, tablet computers (embedded Android or iOS operating system) via a Wi-Fi wireless network connection console to control the Terminal.
LED lamps belong to the cold light source, its small thermal radiation spectrum on plants, plants fill up close can be realized and to avoid burns. In a plant or group of plants in tissue culture, and cultural distance between shelves can be shortened to improve space utilization and the density of plants per unit space. Intelligent control in greenhouse experiments showed that using traditional light sources (high voltage sodium lamp and metal halide lamp) light source fitted with 0.5 kW per square meter, but LED only 0.27 kW, the energy saving more than 50%.
