Some people think that LED lighting has not really started in the domestic market, and the frenzied development will overdraw the future production capacity and market. As the LED lighting industry ushered in the rapid development of the spring tide, many controversies about its overheated investment emerged. Is the prospect of infinity or difficult? What opportunities and challenges does China's LED lighting industry face?
"Infinite prospects" lead the company to profit
“Under the same lighting effect, semiconductor lighting (LED) is more than 80% energy-saving than traditional light sources, and its life span is more than 10 times longer than traditional light sources.†In the Nanchang High-tech Industrial Development Zone, Luneng, executive vice president of Jingneng Optoelectronics Co., Ltd. A semiconductor blue light lamp told reporters.
As a new generation of environmentally friendly light source, LED is known as the most developed green lighting source in the 21st century due to its high brightness, low heat and long life. At present, China has included semiconductor LED lighting in the medium and long-term science and technology development plan, and has now formed an industrial chain of epitaxial wafer production, chip preparation, package integration and LED application.
Jiang Fengyi, vice president of Nanchang University, believes that since last year, the LED lighting industry has begun to develop rapidly from upstream to downstream, and reached the blowout state in the first half of this year. According to statistics, in 2009, China's LED lighting industry, there are nearly 60 upstream enterprises, more than 1,000 mid-stream device packaging enterprises, more than 2,000 downstream application enterprises, and more than 800,000 employed people. In 2009, the output value of the middle and lower reaches of semiconductor lighting was 82.7 billion yuan.
According to the research report of the High-tech LED Industry Research Institute, LED lighting has surpassed the backlight to become the fastest growing application market in the LED market. By 2015, the penetration rate of LEDs in the domestic lighting market will reach 1/4.
Frenzy development exposes industry defects
Although the market expects such a high level, at this stage, due to blind development, China's LED lighting industry has exposed problems such as lack of core technology, insufficient innovation capability, and disorderly market competition.
"In terms of output value, the current penetration rate of LED in the domestic lighting market is only 5%. The core technology relies on imports and the overall cost is a stumbling block to the further development of the LED industry," said Zhang Xiaofei, a doctor of the High-tech LED Industry Research Institute.
It is understood that the main technologies for LED upstream chip production are in the hands of foreign companies, and the process of localization of technology is slow, which has affected the development of the industry. MOCVD epitaxial furnace and its related supporting technology are the highest end of the LED industry chain. At present, it mainly relies on imports, which greatly restricts the cost control of the upstream of the LED industry.
"As far as the overall level is concerned, China and the world's first-class level still have a gap of about two years." Jiang Fengyi believes that "many developed countries and developing countries or regions in the world are accelerating the development of semiconductor lighting technology and industry, in technology. China is in the second echelon."
"If we do not regulate the market, the future will be able to fall to the point of making wedding dress for foreign lighting giants." Jiang Fengyi said.
Industry calls for industry norms
With the continuous growth of lighting in production, living, and urban streets, the role of lighting power in power consumption has become increasingly prominent. According to statistics, China's lighting power accounts for more than 12% of the country's total electricity consumption, and is increasing at an average annual rate of 15%. The market for energy-efficient lighting products as an alternative to incandescent lamps is seeing good opportunities.
In order to make the LED lighting industry develop healthily and orderly, many experts suggest strengthening the country's overall guidance for local LED industry planning, and issuing national industry standards as soon as possible, especially the industry standards for related products in demonstration projects, such as street lamps and tunnels. Lamps, displays, landscape lights, etc., allow local governments to purchase and provide products with standards.
At the same time, we will introduce relevant supporting policies as soon as possible, strengthen the establishment and regulation of testing institutions, avoid some non-conforming test results, and improve the overall testing level and credibility.
Many experts believe that the localization of MOCVD for semiconductor lighting core equipment as soon as possible will fundamentally change the situation of high-end equipment and promote the rapid, healthy and sustainable development of China's semiconductor lighting strategic emerging industries. At the same time, the market competition is becoming increasingly fierce, and it is imperative to strengthen the research and development of the next generation of semiconductor lighting technology.
