As traditional plant factory lighting systems will consume a lot of energy, so the current LED lighting applications in agriculture the most energy-saving potential of a technology. PIDA pointed out that plant seedling plants under fluorescent lighting energy consumption accounts for up to 82% energy consumption. The use of LED alternatives to traditional lighting can significantly reduce lighting energy consumption of these agricultural production. In the Netherlands, for example, in a greenhouse experiment using the LED fill light show, with traditional high pressure sodium and metal halide lamps and other than, LED energy savings of 50 to 80%; factory in plants per square meter when using conventional light sources need to be equipped 0.5kW light source, while the LED requires only 0.27kW, power consumption can be reduced by 50%. Taiwan's share of global market, 25% of the LED element, and thus the LED industry plant factory has recently become a hot topic. As agriculture lighting and general consumer lighting design different from the die package to the IC must be done for the characteristics of the plant factory design, so almost all of Taiwan's LED suppliers have announced to enter this field, and the tentacles extend further to Mainland China . Everlight two years ago with the Netherlands, Philips Lighting, Mitsubishi Chemical, Panasonic (China) electrician, Yangtze Electric, Olin Group, dozens of well-known international companies signed a strategic cooperation agreement. On LED Grow Light lighting, industrial control, air conditioning environmental control, nutrient solution preparation areas such as technological innovation, market development, etc. signed a letter of intent in this field in order to develop some potential LED special lighting products. In addition, Japanese companies StanleyElectric recently introduced the cultivation of fruit trees for indoor LED lighting. The Company calculates the most suitable fruit trees grow irradiation angle and narrow angle LED light irradiation, increased illumination unit area, and with the way sunlight can be reduced harvest time. The company plans to launch in the near future on the market can accelerate the growth of plants for indoor use LED plant lighting. But no matter what kind of artificial light, there is a problem of electro-optical conversion loss and waste heat, waste heat in a confined indoors need to consume large amounts of air emissions; followed by irradiation lamps must be able to concentrate and exporting heat planted areas designed to improve plant efficiency, which in turn involves the LED chip package and luminaire body design, so artificial light plant factory is very important to choose a ring.
