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
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.
Core equipment is expected to be "made in China"
The development of the semiconductor lighting industry will also drive the rapid development of the domestic semiconductor lighting equipment manufacturing industry. Li Jinxi said that at present, the LED packaging production line with high level of extension, chip and automation is almost 100% imported, and even the most basic parts and materials are almost imported. The annual import volume of semiconductor lighting equipment and accessories is about 1 to 150 million US dollars. To cultivate an internationally competitive Chinese semiconductor lighting industry, it is necessary to have core equipment and low-cost manufacturing equipment.
"Semiconductor lighting equipment has lower technical requirements than integrated circuit equipment. Semiconductor equipment suppliers mainly focus on integrated circuits. Due to the small market share of LEDs, major manufacturers pay less attention. Some relatively small companies in the world are in semiconductor lighting. The development of process equipment is particularly active. Since the LED industry market is still in the market gestation period, its upstream, middle and downstream industrial structure is still incomplete. Whether it is qualitative or quantitative LED production equipment is not developed, the country has a chance to make it. "Li Jinxi said.
In terms of equipment, except for a few equipments that need to be tackled, most of the equipment can fully meet the needs of the development of the LED lighting industry as long as it is adaptively developed on the basis of semiconductor equipment development technology. Li Jintao said that it is estimated that the domestic semiconductor lighting equipment market will need 800 million US dollars in the next five years, and LED packaging equipment manufacturers have the opportunity to produce in China.
"On the one hand: In recent years, Japan's Taiwan LED packaging factory set up factories in the mainland. Due to the continuous decline in LED market prices, LED packaging manufacturers are constantly seeking low-priced equipment to meet production, and localization of production equipment is urgently needed. On the other hand: The rapid growth of China's semiconductor lighting industry and market, the increasing demand for high-quality LEDs provides a good external environment and huge development space for the demand of LED packaging equipment."
Save 10 thermal power plants a year
The biggest influence of semiconductor lighting on indirect related industries is the power industry. Experts predict that in 2010, semiconductor lighting will enter the 5%% general lighting market, which can save 50 billion kWh annually. It is equivalent to 10 thermal power plants with a capacity of 2.2 million kilowatts, which can save 10 to 120 billion yuan in electricity construction. After deducting the investment in LED construction funds, the actual social expenditure can be reduced by 800 to 100 billion yuan.
The development of the semiconductor lighting industry will promote the development of the solar photovoltaic cell industry. LED is low-voltage, direct-current electricity, which is very compatible with the low-voltage and direct-current power supply of solar photovoltaic cells. The combination of the two does not require an AC inverter and truly realizes new energy. Combined with a new light source. Li Jinxi said that China has become an important production and export base for solar semiconductor lighting products. With the development of power LEDs, solar semiconductor lighting street lamps have begun to be used in domestic communities and garden construction, and many villages in western China have no electricity. Supply, solar semiconductor lighting will become an effective way to solve the lighting in the area without electricity, and accordingly will drive the further development of the solar photovoltaic cell industry.
Therefore, the implementation of the semiconductor lighting project will promote the consensus of social energy conservation and environmental protection, lay the foundation for sustainable development in China, and promote the use of semiconductor lighting, which will greatly improve environmental benefits. Due to power saving, it can reduce the environmental pollution caused by carbon dioxide, sulfur dioxide, nitrogen dioxide waste gas and dust emitted by coal burning in power plants. It is predicted that the annual reduction of carbon dioxide emissions will be more than 6 million tons, and there are no problems such as fluorescent lamps and energy-saving lamps containing mercury.
"So, semiconductor lighting is a strategic high-tech industry that is likely to achieve leap-forward development in China. It is in line with the major needs of China's social and economic development and has broad prospects for industrialization," said Li Jinxi.
