Leading the level, forming a complete semiconductor lighting industry chain.


In the construction of the four major industrial bases, relying on Qingdao, the leading economic city in Shandong, will give full play to the scientific research advantages of Shandong universities and universities, and develop and produce SiC substrate materials and various LEDs, LD epitaxial wafers and photovoltaic cells. As the main body, expand LED, LD die manufacturing, packaging, semiconductor lighting and photovoltaic products research and development production capacity, improve industrial concentration, and build a national leading semiconductor lighting industry base. At the same time, Shandong Province will accelerate the cultivation of applied enterprises, select a number of key projects, landmark buildings and landscapes as well as public places, and carry out the construction of semiconductor lighting application demonstration projects through government procurement and price subsidies.


At the end of 2010, Qingdao launched the key projects closely related to the “Circle Bay Protection and Bay Development” strategy: the submarine tunnel, coastal lighting, subway construction and other lighting projects, and the demand for outdoor lighting projects is expected to exceed RMB 2 billion. After the 4th development of the 5th Qingdao International Lighting Exhibition in 2010, it has become the largest and most influential professional exhibition in Shandong Province. The convening of this year's booth will be an excellent platform for major enterprises to expand the northern market, both in terms of time schedule and regional influence.
