Although the "Eleventh Five-Year Plan" has just started more than a year, Li Jintao, a member of the overall expert group of the National 863 Program's major project for semiconductor Lighting projects, is well versed in this account: when the project is completed in 2010, China's semiconductor lighting output value will reach 1000. The scale of 100 million yuan is calculated by entering the 5% general lighting market. The annual energy saving is more than 50 billion kWh. After deducting the investment in LED construction funds, the actual social expenditure can be reduced by 800 to 100 billion yuan. An attractive industrial chain is like many high-tech industries. Semiconductor lighting is not an independent and closed technology.
"If we occupy the commanding heights in this war without smoke, we will encourage our country to develop internationally competitive efforts with independent intellectual property rights and core patents." Li Jinxi said that with the development of the semiconductor lighting industry as an opportunity, it will drive other related raw materials. , equipment manufacturing, automotive and other industries. In addition, white LED technology with independent intellectual property rights will greatly enhance the competitiveness and status of China's semiconductor lighting appliances in the international arena. The direct related industries of semiconductor lighting are mainly upstream new materials industries, such as metal gallium, rare earth metals, sapphire/silicon carbide/silicon, etc., and downstream industries such as automobile manufacturing and electronic information based on LED-based original devices. For the upstream new materials industry, the direct raw materials for producing high-brightness LED lighting devices are trimethylgallium, rare earth luminescent materials (such as rare earth phosphors), high purity nitrogen, sapphire/silicon carbide/silicon, epoxy resin, etc. The mineral resources traced back to these raw materials are mainly rare elements such as gallium, rare earth metals, silica, coal and aluminum. "Therefore, the promotion and application of semiconductor lighting has expanded the application of resources on the one hand; on the other hand, it has increased the utilization value of resources and promoted the rapid development of these upstream industries." Li Jinxi said. For the downstream industry, LED lighting devices play a leading role in the automotive industry, electronic information industry, construction industry and other applications, which can improve the industrial structure in these areas, promote industrial upgrading, and enhance the competitiveness of products.
