On September 17, 2014, Osaka Prefecture University disclosed the internal situation of the Greenhouse Clock New Generation (GCN) plant factory at Osaka Prefecture University. The plant uses LEDs for plant cultivation developed by Philips Electronics Japan (Headquarters: Tokyo, Philips for short). The large plant is built in the Osaka Prefecture University Campus and is the fifth largest plant in Japan. It opened on September 19th, October. It was officially put into production in the first ten days. Philips hopes to accumulate technical experience through the plant factory to sell its products in Japan. The plant uses 13,000 Philips GreenPowerLEDProductionModules. This is the first of its kind to be equipped with far-infrared (near 750nm) LED chips that emit red, blue, white and far-infrared light. . The lighting used in plant factories is usually red, blue and white, because red and blue light contribute to plant photosynthesis. The use of far-infrared light at the same time can complete the shape of the leaves during plant growth, improve the efficiency of photosynthesis, and accelerate the growth rate. Osaka Prefecture University said: Because it promotes plant growth and has excellent dust and water resistance (Ansei Masaichi, Director of the Plant Factory Research Center of Osaka Prefecture University), GreenPowerLEDProductionModule is used. Plants such as lettuce are only needed for planting and harvesting. 40 days or so. According to the company, this type of lighting can reduce cultivation time by up to 20% and power consumption by 55% compared to ordinary fluorescent lamps. Since the amount of heat generation is also small, it is also possible to save electricity for air conditioning for managing temperature. The plant factory was built through a joint project of industry, academia and government with a number of companies including Osaka Prefecture University. Covering an area of ​​about 1300m2, it can produce 5,000 green leafy vegetables such as vegetables every day. The vegetables produced will be directly supplied to the supermarkets and restaurants in Osaka Prefecture. Since the vegetables carry less bacteria and have a short transport distance, the storage time is nearly twice that of open-air cultivated vegetables. Although the price will be higher than ordinary vegetables, it will be commercialized by ensuring quality and establishing a stable supply system. If you need it, you can also produce high value-added vegetables such as potassium-free (K) vegetables.
