“This is just the beginning.†In 2012, Xurui Optoelectronics will produce 6-inch LED chips with a luminous efficacy of more than 120 lm/W. Before 2014, Xurui Optoelectronics will become the first factory in the world to produce 8-inch LED chips. At the opening ceremony, Mr. Ma Ke, the general manager of Xurui Optoelectronics, vowed to say.
According to reports, Xu Rui Optoelectronics broke ground in February 2010 and officially put into operation in March 2011. Its total investment exceeds 350 million US dollars and is implemented in three phases. The initial investment is about 600 million yuan, and the production capacity will reach 20 KK / month (1 mm * 1 mm chip). According to the plan, the project is expected to be completed in the third phase of the end of 2013. At that time, it will have 60 MOCVDs, which will be able to mass produce LED epitaxial wafers of 4 inches or larger and high-power, high-brightness LED chips at the same time. 130lm/W.
It is reported that Xurui Optoelectronics Co., Ltd. is jointly invested by the United States SemiLEDs Corporation and several LED companies in China, specializing in the production of high-power high-brightness LED chip products. Its LED chip project is the only project invested by SemiLEDs in mainland China, covering an area of ​​100 acres with a total investment of more than 350 million US dollars. 
It is reported that Foshan is currently an important production and R&D base for traditional lighting sources in China. The development of the semiconductor lighting industry has become an important part of Foshan's implementation of the “Planning and Development Plan for the Pearl River Delta Regionâ€, accelerating industrial transformation and upgrading, and building a modern industrial system. Important initiatives. As the core area of ​​Foshan electric light source lighting industry chain, Nanhai District has a complete industrial chain and strong integration and support capabilities in the upstream and downstream of the industrial chain. With the successful development of MvpLEDTM technology (metal-based vertical structure LED) by the company's SemiLEDs, Nanhai District plans to occupy the high-end LED industry and build a well-known semiconductor lighting industry base in China.
When the grid is cut off, the three-phase dump load of the Controller will automatically start to work and the Inverter will stop output to grid. When the grid resuming, the controller stops three-phase dump load and the inverter will resume power supply.
The inside of the controller is equipped with surge protector. Contain the over voltage into the Wind Turbine under the bearable voltage of the equipment or system. On another way, to conduct the strong lightening current into the earth directly to avoid any damage of equipment.
