The world's largest LED lighting plant factory

　　Japan Mirai Inc. (Headquarters: Tokyo) in Miyagi Prefecture Tagajo building with all the lights in all foster artificial light type LED plant factory. According to the company, this is the "world's largest" full LED lighting plant factories. Produce 10,000 lettuce a day.

　　Mirai will be located within Sony's Sendai Technology Center, "Miyagi Renaissance Industrial Park," the transformation of existing buildings into plant factories. As one of the activities funded Northeast METI Economic Bureau, Mirai had to technology development and cultivation environment for plant factories LED lighting development as the theme, with GE Japan joint empirical experiments. Development, design, construction and cultivation racks throughout the facility responsible for the Japanese construction company Kajima.

　　The most important feature of the plant is the use of GE plants in Japan to develop LED lighting factory, using a uniform dispersion of both high directivity LED light irradiation but also according to the growth stage of the plants of different wavelengths of light technology. For example, out of the nursery room after the initial phase, will be illuminated white and red LED light mixed together whitish light to promote photosynthesis. Then again illuminated by a reddish light with red and blue LED light emitted by the LED lighting to promote the growth of leaves and roots. When approaching harvest will irradiation whitish light again to promote photosynthesis. After using this method, when compared with using only fluorescent, not only to reduce power consumption by 40%, the same harvest area also increased by 50%. In addition, the Mirai did not disclose the specific wavelength of light technology and LED lighting related.
