The day before, the domestic first independent vertical structure of innovative high brightness LED technology industrialization projects, the successful trial of Shaanxi new light source technology Co. Ltd., and lit up the vertical structure of the domestic independent innovation LED lamp. The smooth implementation of the project is to vigorously promote the integration of industry, University and Research Institute, the implementation of the thousands of people plan to optimize the industrial development environment. From the signing of the project to achieve industrialization, with less than two years, a record of Shaanxi's Shenzhen speed".
The vertical structure ultra high brightness LED technology industrialization project is the Xi'an Jiao Tong University solid state lighting engineering research center of scientific and technological achievements transformation project, mainly produces the high power LED chip which is used in the function illumination. The technical process using substrate stripping, the extension of the heat conduction substrate transfer to the metal substrate with excellent thermal conductivity on the epitaxial growth of thin film devices and substrate stripping device makes the LED heat dissipation problem forward to completely solve the core fragment, chip, package and light source due to the small power, bad heat dissipation no consistent, high cost and low reliability etc.. High current density, produced using the technology of ultra high power and large size LED chip, to achieve improved chip light emitting unit area several times or even ten times, greatly reduced the cost of production and use of LED lighting source, improve device reliability, really play the high-end semiconductor lighting chip, high brightness, high efficiency set in one of the advantages of reliability.
The project is a "thousand person plan" scholar Dr. Yunfeng is the technical leader of Xi'an Jiao Tong University. According to him, the semiconductor lighting industry has broad market prospects. If the domestic 1/3 of the lighting replaced by LED semiconductor lighting, the annual savings of 300 billion kwh of electricity, equivalent to a Three Gorges power generation. The international market is very broad, only the domestic market size of 450 billion yuan per year. However, due to its high technical barriers, the ultra high brightness semiconductor lighting chips are only a few industry giants in the world. The project successfully achieved industrialization in our province, means that the semiconductor lighting industry in China entered the upstream industry chain of high-end LED epitaxial wafer and chip manufacturing, has important significance to improve the strategic position of our province semiconductor lighting industry and the international status.
In the process of industrialization of the project, the provincial Party committee and government attach great importance to the project approval from the financing to give a full range of support. From August 2011, signed investment agreement in Xi'an, to the industrialization of the company in December of the same year, the project of Shaanxi new light source technology Co., Ltd. was formally established, and then the vertical structure of LED in June this year, China's first independent innovation lighting lamps, the project in less than two years has completed the "empty talk" to have the scale of industrialization.
It is expected that the project will be completed in the near future trial production, and gradually achieve mass production, to achieve an annual output of 130 thousand epitaxial wafers, the production capacity of 180 million ultra high power vertical LED chip, sales revenue of more than $200 million.
