In recent years, LED Grow Lights permeability increase, the output value of the global LED Grow Lights began in 2013 showed rapid growth, although only ten million U.S. dollars output value scale, but expected in 2014 will exceed $ 35 million, in 2017 is expected to challenge more $ 300 million.Topology Research Institute Center researcher Linpei Xuan optoelectronics industry, said 2013 LED Grow Light costs have fallen sharply compared to 2010, when each lumen of about NT $ 0.38 yuan, 1.8 yuan in 2010 only 1/5, and thus promote the Philips, Osram, Mitsubishi, Panasonic and other international companies, have invested in innovative applications of LED plant factory, both LED and two industrial advantages of agriculture in Taiwan, of course, do not want to miss the opportunity to add to agricultural science and technology innovation, so that one hundred million yuan worth of corporate promotion .Plant Factory originated in 1957 in Denmark due to lack of sunshine hinder plant growth development, and later Japan, the U.S., the Netherlands have invested, however, the cost is too high, lack of skills, experience and other factors is poor, leading to poor management, until the 21st century, due to the greenhouse worsening effect until renewed public attention.As the demands of factory plants are replaced by artificial sources of natural light, the plants were moved from the outdoors indoors, so that changes in plant growth from environmental impact, in the past the high cost of LED lighting, plant factories which use more fluorescent lamps or high-pressure sodium lamps, with LED prices drop and technology to enhance, promote the application of LED plant factory appeared in a new wave of progress.
