LED agricultural lighting hot food safety remains to be seen

LED lighting to speed up development, its application is gradually expanding. Among them, LED agricultural lighting in recent years, many companies actively involved in the field, including Japan, China and other regions are also actively imported. Although all for LED lighting applications in flower planting, multi positive view (because only for ornamental flowers), but for LED lighting used in edible agricultural products planting, while there are also different opinions. The main reason is because of the artificial light environment, the growth of crops, edible whether it will have any impact on the human body (or even harm), there is still lack of sufficient research data for reference. This and genetically modified food (genetic engineering) brought doubts about. With the plant factory (plant growth environment with a lot of artificial intervention, including artificial light, temperature, humidity, nutrient and water etc.) rise, we can not help but think of those genetically modified soybean products, containing genetically modified ingredients of corn and feed the genetically modified food brings a variety of security disputes. Although some research report pointed out that the consumption of foods containing genetically modified ingredients in the short term, there should be no immediate harm to human body. But the long-term impact, but it takes time to verify. And a large number of artificial light source environment for the cultivation of crops, edible after the impact on the human body, but also the lack of adequate research data available for reference. However, agricultural import artificial illumination, not from LED to. As early as in the past, it has used a lot of fluorescent lamp, high pressure sodium lamp and other artificial light source, used in greenhouse. LED lighting, because the energy (power consumption only 1/8 incandescent lamp and fluorescent lamp 1/2), mercury, adjustable light (quality and quantity), low cooling load, small volume, and brachytherapy plants, improve the utilization of the characteristics of space plant growing, even. LED light source characteristics can promote plant growth, regulation of plant morphology, so popular. Especially as a large agricultural country China, LED lighting applications for the development of agriculture in recent years, is regarded as an important index of. China in 2006 to build the local first sets of closed LED artificial light plant, while the development of LED light environment control software and light environment control device. In 2009, first intelligent plant plants with LED and fluorescent lamp as artificial light source were piloted in Changchun. At the end of 2010, the Chinese Academy of Agricultural Sciences held the plant factory Innovation Conference ", and separately with PHILPS lighting, MITSUBISHI chemical, Matsushita Electric, Everlight electronics and many other well-known enterprises, for LED Lamps lighting, industrial control, air conditioning control, nutrient solution preparation technology innovation and market development project signed a strategic cooperation protocol. There are indications that China attaches importance to the development of LED lighting applications in agriculture. At this stage the main industry attention for LED agricultural development of lighting, or focus on cost, technology, and application of the standardization of products, LED and general commercial or home lighting on roughly the same. Among them, the cost is also considered as a key factor in determining the speed of agricultural lighting LED. Because the cost of LED agricultural lighting is still higher than the traditional high pressure sodium lamp and fluorescent lamp.
