The problems and the key to the development of LED industry

LED huge market potential, many LED companies competing to enter. The traditional lighting industry giants have entered the LED industry, the international high brightness LED market since 1995, an average annual growth rate of 58.5%, reaching $1 billion 840 million in 2002. Chinese Academy in the early 60s to carry out scientific research led. In 80s, China's LED began to shift from research to production, to form a scale in twenty-first Century. 2002 China's LED production enterprises reached 420, more than 3 employees, production of more than 15 billion, the output value of more than 8 billion yuan. 2003 LED output value of more than 10 billion yuan, production of about $20 billion, of which the ultra-high brightness LED. In recent years, the development speed of LED over 30%, of which the development of ultra-high brightness LED over 50%.

China's LED industry is the introduction of the core of the early packaging, low technical threshold, a labor-intensive industry. At the end of the last century, the introduction of epitaxial wafer processing, and then to carry out research and development of high technology epitaxial wafer and small batch production. At present, in addition to the use of liquid phase epitaxial growth of low brightness red LED, with MOCVD growth of ALGaINP red, orange, yellow LED, InGaN blue, green and ultraviolet LED epitaxial wafers and tube core has entered the production, but the scale is still small.

China solid state lighting coincided with the development opportunity, Shanghai, Nanchang, Dalian and Xiamen has become the country's four largest semiconductor lighting base. Deputy director of the national semiconductor lighting project coordination office Wu Ling pointed out that, compared with the international advanced level, now China semiconductor lighting technology behind 3 - 5 years, to China existing technology base and industrial base, is expected by the overall stage of promotion, formed China semiconductor lighting industry is the core competitiveness of the final.

Problems in the development of LED industry

We used to produce LED optoelectronic components, to Taiwan and Hongkong, a number of lighting factory supply LED, but their products only for export. With the tense situation of the domestic power day by day, LED as an environmentally friendly energy-saving products in the country has become imperative. Therefore, we take the opportunity to enter this field.

At present, the general problem of LED industry is the choice of LED. At present, many companies do not produce LED, to ensure the quality of the LED, only to the outside world to buy a lower price of LED to assemble, resulting in brightness is not ideal, the reliability of the unstable shortcomings. Followed by the design problem, some enterprises do not have a professional design talent, there are some problems in the design, the user is more difficult to identify its good or bad. The quality of instability caused by the loss of confidence in the consumer LED, thereby affecting the entire industry, which is the biggest problem LED companies.

To promote the development of LED lighting, energy conservation awareness into energy conservation actions, government, business and business sectors should take the lead. Only people from all walks of life are fully aware of this, the popularity of LED will not be too far away from us. Like the beginning of the use of incandescent lamps, and later with a fluorescent lamp, and then use the same trend as energy-saving lamps, the future will certainly be universal LED lights.

Three key points of LED enterprise development

In recent years, a large number of LED manufacturers have emerged, LED products are gradually applied to the lighting industry. However, due to the LED technology is not mature, although the potential of the LED market is huge, but now the situation is mixed, disorderly competition and poor LED products flooded the market. Over the past few years, we have been in the LED market competition has made considerable progress and development, about 3 months to launch a new variety of up to 4, R & D costs of $200 thousand.

Now the LED market can be described as price chaos, competition chaos, poor product quality. The key to the development of LED enterprises in three areas. On the one hand is the enterprise self-discipline, to ensure the quality of LED products; on the other hand, is an urgent need for industry management norms LED market; how to promote LED products, is also one of the key elements of enterprise development. LED products in the optoelectronics industry and lighting industry scenery unlimited, but in the minds of the people is very strange. Therefore, it is necessary for the industry to introduce and promote LED products.

Many LED companies have not yet realized the path of brand development. Therefore, LED companies must be aware of this, the brand is the ultimate development of the road.
