The LED illumination to speed up development, its application field is also gradually expanded. Among them, LED lighting is agriculture in recent years many manufacturers positive set foot in the field, including Japan. China and other regions besides actively introduces. Although at present the from all walks of life to RGB strip led application for planting flowers, a definite view (because flowers used only to watch), but, for use in led lighting will ShiYongXing agricultural planting, is still there are different opinions. Mainly because of artificial light environment of the growth of the crops, after eating whether the human body to produce any influence (or even warm), still lack of sufficient research material enough for reference.
This and genetically engineered food (genetic engineering) brought about by similar doubts. As plant factory (plant growth environment with a large manual intervention, including artificial light, temperature, humidity, nutrient and moisture, and so on) rise up, everyone not associate to those genetic modification and soy products, contain genetically modified ingredients such as feed the corn and genetically modified food brought about by the various safety controversy.
Despite the fact that some research report points out, eat the food with gm ingredients, short-term inside the human body should not immediately to sexual hazards. Nevertheless, how long-term effects, but need time to test and verify. And the use of artificial light environment of the training of the crops, after eating the influence of the human body and how, at present also lacks sufficient research material available for reference.
However, agricultural import artificial lighting, not from ribbon led strips began. As early as in the past, he has used various fluorescent lamp, high-pressure sodium lamp and artificial light, used in the greenhouse. And the appearance of LED lighting, department for have energy-saving (power consumption of incandescent lamp, fluorescent lamp only 1/8 of 1/2), do not contain mercury, adjustable light (the quality and quantity), cooling load low, small volume, and can close illuminate plants, improve plant cultivation of characteristics such as space utilization, even through LED light source characteristics also can promote plant growth and adjusting plant form, so popular.
Especially as the large agrarian nation of China, in recent years to the development of agriculture LED lighting applications, also as an important index. In 2006, China to build the first set of native plant equipped with LED artificial light factory, and develop LED light environment control software and light environment control device. In 2009 the chief seat using LED changing trial and fluorescent lamps as artificial light of intelligent plant factory.
By the end of 2010, China academy of agricultural sciences and held the “plant factory innovation achievement conference”, and philips lighting, respectively with microbial chemical, materiality electric, light electronic and a number of famous enterprises, LED lighting source for plant light, industry control, air conditioning system of environmental control, preparation technology innovation and market development projects signed the strategic cooperative agreement. There are signs that China LED lighting applications for pastoral development attention.
At present the industry for rigid led strip the primary concern of development, or focus on cost, technology, and relevant applications product standardization, and led the general commercial or household lighting concerns about the same. Among them, the cost and is considered as the decision LED lighting popularization of agricultural speed key elements. At present, LED lighting because agricultural costs, nevertheless higher than conventional high-pressure sodium lamp and fluorescent lamp.
