There are more and more examples of LED lighting applications in the agricultural sector. According to the results of the cooperation between Taiwan’s “Council of Agriculture†and the Institute of Industrial Technology (ITRI) recently, to assist Nantou’s production of white shoots, they use LED lighting to control agricultural products. The period of production, and to prevent dwarfism, harvested twice a year from the original, increased to harvest four times a year. In other words, fresh white bamboo shoots can be eaten in four seasons of the year.
The “Council of Agriculture†stated that in 2009, the area planted by white bamboo shoots in Taiwan was more than 2,000 hectares, and the area planted in Nantou County was 90%, with a value of NT$1 million per hectare. According to the experience of the base rot and dwarfism in the 2000-year-old Puli field, Huang Jinxing, an assistant researcher at the Agricultural Research Institute of the Agriculture Commission, found that dwarfism did not appear as long as bamboo shoots were lit under street lighting. They began to plan for the night-time irradiation of white bamboo shoots. The metal sodium lamps were used in 2004, but the brightness was too strong. There were also differences in the agricultural products in different blocks.
In October 2010, the ITRI installed LED lighting in the Nanbai-Jinbai field, which was approximately one-fifth of the ground, and was harvested in the spring of 2011. The second installment of the LED lighting installed by the ITRI later expanded the area of ​​the white bamboo shoot field to the first place.
According to Taipower’s tariff calculations, the annual consumption cost of the Puli Bianbaisun is about NT$50 million. According to the calculation of the ITRI, the first phase has already saved 50%, and it is expected that after the second phase, 90% will be saved. Electricity fee.
In addition, ITRI also uses the spectral range that is helpful for plant photosynthesis and selects red and blue LEDs for lighting planning. It is estimated that white bamboo shoots can be harvested in the coming year.
With regard to the development of LED lighting applications in agriculture, it should be expected and actively invested.
Solar technology will become one of the future green energy technologies. Solar or photovoltaic (PV) is increasingly used in China. In addition to the rapid development of government-supported photovoltaic power plants, private investors are also actively building factories and planning to put them into production worldwide. Solar components.

Many countries are still in the learning phase. There is no doubt that in order to get the best profit, companies in the industry need to learn from countries and companies that have years of experience in solar applications.
Building a cost-effective, profitable photovoltaic power plant represents the most important goal and core competencies of all solar manufacturers. In fact, profitability depends not only on the efficiency or high performance of the solar modules themselves, but also on a range of components that appear to be not directly related to the components. However, all of these components (such as cables, connectors, junction boxes) should be selected based on the long-term investment objectives of the tenderer. The high quality of the selected components avoids the inability of the solar system to be profitable due to high maintenance and maintenance costs.
