China is expected to save energy through new materials and technologies such as light-emitting diodes (LEDs) and make it play an important role in many fields, which means that a market with huge potential is forming.
Great market potential
According to experts, as a light source, LEDs have at least an advantage in terms of energy conservation. The National Green Lighting Project Promotion Project Office has conducted a special survey. The national lighting power consumption is more than 300 billion degrees per year. All the incandescent lamps are replaced by light-emitting diodes or partially replaced with fluorescent lamps, saving 1/3 of the lighting power. This means saving 100 billion kWh, equivalent to the total investment of more than 200 billion yuan, the annual power generation of the Three Gorges Project under construction. For China, which has caused energy shortages due to rapid economic development, this is undoubtedly of great significance and obviously helps to alleviate energy shortages. In addition, the light-emitting diode is sealed with epoxy resin and other materials. The structure is firm and the service life is up to 100,000 hours. It is 10 times longer than fluorescent lamps and 100 times longer than incandescent lamps. In terms of environmental protection, the replacement of fluorescent lamps with light-emitting diodes avoids secondary pollution of mercury leakage from fluorescent tubes.
At present, there are LEDs in mobile phones, computers, digital cameras and cars that people use every day. Even some small switches on electrical switches and TV remote controls are made of this material. And some scientists have used LED lamps for disinfection and air purification, and even used to promote crop growth. The miner's lamp made of it has no sparks and will not cause gas explosion, which greatly improves the safety of underground operations. The miners no longer have to work with large and heavy power supplies all day long. In traffic lights, instrumentation indicators and urban landscape lighting, LEDs have been widely used.
Government: Fully promote
The most attractive prospects for the LED industry may not be the applications currently seen. Many experts in the world believe that in the 21st century, the optoelectronics industry may replace the traditional electronics industry as the largest industry, and become an important indicator to measure a country's economic development and overall national strength; and LED is the most important optoelectronic material in the optoelectronics industry. And components, the foundation of the entire optoelectronics industry
It is reported that in the next five years starting this year, the Chinese government will promote the semiconductor lighting project as a major project. At present, the Ministry of Science and Technology has approved Shanghai, Dalian, Nanchang, Xiamen and Shenzhen as industrial bases.
In June last year, Shenzhen “National Semiconductor Lighting Engineering Industrialization Base†was laid in the Guangming High-tech Park in Baoan District. The goal of the industrial base is: By 2010, there will be more than 200 upper, middle and lower reaches and applied product companies, with annual sales revenue. Near 100 billion yuan, foreign exchange earned more than 2.5 billion US dollars.
According to the construction phase of Nanchang City, by 2010, its semiconductor luminescent materials and devices, display lighting sources and LED lamps will reach an annual economic scale of 10 billion yuan.
Xiamen has given the optoelectronic industry as a new type of industry with policy support and funding. Xiamen Hi-tech Zone has decided to set up a photonic incubator to provide professional services and support to technology-based SMEs in terms of capital, technology, talents and management, with the experience and advantages of entrepreneurial incubation, to promote rapid growth and accelerate From the incubator to the incubation industry, it quickly cultivated an industrial chain and industrial belt. According to experts, by 2010, the scale of Xiamen's optoelectronics industry will reach 20 billion yuan.
After roughly calculating the targets of these five major industrial bases, the relevant parties said that by 2010, the entire Chinese LED industry will exceed 150 billion yuan.
Enterprise: chasing light and electricity
"As long as there is light, LEDs can be used. If only hundreds of billions of lights are used instead, the space in this market will be incalculable. Huang Zhenchun, CEO of Ao Lei Optoelectronics Co., Ltd., said that global luminous in 2010 The diode market will reach 50 billion US dollars, and China is 60 billion yuan (about 7.5 billion US dollars).
"From the 12.5 billion yuan in 2004 and the output value of more than 25 billion yuan in 2005, it can be seen that China's LED industry is in the process of steady growth."
It is understood that outdoor decorative lighting accounts for almost a quarter of China's LED market. In 2004, the value of this market was $1.4 billion. In Fujian Province, 500 million white LEDs are needed every month.
So far, most of the billboards in China's cities use inkjet and spotlight illumination. The visual effect is the effect of inkjet reflection, which requires high illumination, while the use of LEDs does not require reflection, so billboards will be more and more. Let the light emitting diodes. According to a report released by the National Semiconductor Lighting Coordination Leading Group Office, by 2008, China's urban landscape lighting market will reach about 20 billion yuan, becoming the largest application field in the LED market.
However, experts also said that China's LED industry is facing a huge problem, that is, the technical level is relatively low. "Compared with the regions where the world LED industry is relatively developed, China is just in its infancy. In addition to technology, it is still in a relatively downstream stage in terms of industry scale and production capacity: China's current annual output value is about 1.5 billion US dollars. Less than half of the $3 billion in Taiwan in 2004 is not comparable to the $2 billion of a Japanese company in 2004." Huang Zhenchun pointed out.
In fact, like “Ao Leiâ€, many domestic companies have made up their minds to move upstream in the value chain of the LED industry. In the face of the current situation that many LEDs, especially high-end products, still rely on imports, many domestic companies have begun their own "conquest journey", and there are still many companies ready to join the ranks.
