Chongqing Silian Optoelectronic Science & Technology Co., Ltd. (referred to as "Silian optoelectronic" or the "company") is China Silian Instrument Group Co., Ltd. (referred to as "Silian group") based on the successful acquisition of Honey Well Company USA sapphire factory, in 2008 July formed. After several capital increase, the company registered capital of 500000000 yuan. The company's main business is the artificial sapphire wafer, and LED devices and LED lighting product development, production and sales.

        The company has the first of China's capacity for growth, development process and the world's top quality large size sapphire, independent research and development of 6 inches sapphire wafer lining body, through the success of the epitaxial growth of Philips testing, to become the world's advanced level of large size wafer preparation technology and standards of the enterprise, to meet the highest requirements within the industry, as OSRAM, Philips etc. top lighting manufacturers preferred partners and suppliers. Quadruple optoelectronics company with its world leading technology and strength, has become an important member of the SEMI industry associations to participate in the production of large size sapphire international standard.

        The technical level of packaging products to reach the domestic advanced level, and mobile phone backlight, display, lighting industry, the top position of the customer to establish relations of cooperation. Packaging products company 2012 annual CCTV Spring Festival Gala has become the sole supplier, with its stable quality and advanced by the vast number of users.

        In LED applications, through independent research and development, companies in the LED street lamp, LED fluorescent lamp, LED lamp, traffic signal lamp, LED LED flameproof mining lamps and many other fields for more than eighty patents, more than fifty patents. Related products have passed the CE, ROHS technology and explosion-proof certification, product technical indicators higher than the level of domestic counterparts. The company relies on the LED energy saving products resource advantages, actively introduce the contract energy management mode, to carry out R & D, energy-saving products and engineering reform and related technical services, market share rapidly, has become the backbone enterprise of domestic energy services.

        In 2010 October, the company successfully settled in two rivers area Tsai LED Industrial Park covers an area of 1000 acres, plans to build a sapphire and LED industrial park. By the end of 2010, a company 320 acres of sapphire and LED Industrial Park, 32000 square meters of production plant completed and put into use in 2011, after the operation, the formation of an annual output of 3000000 or 2 inches sapphire substrate, 1200000000 LED package, 28000 kW LED lighting production capacity; the two phase of the project covers an area of 95000 square meters, construction area of 130000 square meters is also active in the start.

        Looking to the future, the company will continue to uphold the "people-oriented, survival of the fittest in natural selection, inheritance and innovation, the pursuit of excellence" spirit of enterprise and "quadruple in the user side, the user in the quadruple heart" service tenet, with sapphire products as a leader, LED packaging products as the main line, the engineering application of LED product support, closely follow the international trend of development of LED, play LED international leading substrate material preparation technology, extend the industrial chain, expand the industrial scale, improve industrial concentration, the lower the advantage resources to attract, integration, to maximize the role of radiation, the formation of industrial agglomeration of ten billion scale, the company built for China and the Asia Pacific market globalization LED product supply base, China the most complete industrial chain, operating the largest semiconductor lighting industrial base, to create energy-saving, environment-friendly society, and make greater contributions to the new development of industry.
