The lack of scale effect LED lighting for industrial upgrading

Semiconductor lighting (LED lighting), is a new generation of cold light source developed in the last century in 90s, has a long life, low maintenance costs, environmental protection and energy saving features. These technical advantages laid a good foundation for the promotion of LED. People in the Olympic Games opening ceremony, the Spring Festival gala evening on some occasions, can find the LED product figure, it is cleverly implanted in the stage of technical personnel, and program integration, to the audience showing a magnificent visual effect. In addition, a lot of infrastructure is now widely used LED products, making it more widely used.

Policy support to accelerate the implementation of

Lighting energy consumption accounted for a larger proportion of the total electricity consumption, the U.S. Department of energy's survey data show that the country's electricity consumption in the field of 22%% lighting. China's lighting energy consumption is not optimistic, in Shanghai, for example, lighting electricity consumption accounted for more than 1/3 of the city's electricity consumption in Shanghai, this figure is rising trend.

Therefore, all countries have carried out a series of energy saving measures: the United States plans within 12 years, the phasing out of incandescent lamp, switch to new energy saving and environmental protection, new energy saving than traditional bulbs lights will be 70%%; the Australian government announced a total ban on the use of incandescent lamp in 2010; in January 21, 2008, Chinese the Ministry of finance, the national development and Reform Commission jointly issued the "Interim Measures" efficient lighting products to promote financial subsidies to fund management, focusing on efficient lighting products to replace incandescent and other inefficient lighting products, the financial sector focusing on 5 categories of products: Lighting self ballasted fluorescent lamps for general lighting (commonly known as energy-saving lamps), three color double straight tube fluorescent lamps (T8, T5 type), metal halide lamp, high-pressure sodium lamp, electric light source products, semiconductor lighting products and the necessary ballast. In this policy, all over the country have launched a campaign to promote energy-efficient products.

Bright future twists and turns

Despite the many advantages of LED products, but the industry has different views on its development trend.

Some people think that the cost of LED lighting and some supporting technology (heat, light etc.) and traditional lighting can not compete, the outlook is not optimistic; some people think that the current LED lighting industry has matured, in the near future can replace the traditional lighting lamps. These two views are biased, the former too much emphasis on the difficulties, ignoring the development of the lighting product itself; the latter is somewhat blind optimism. China Lighting Association chairman Chen Yansheng said, LED lighting industry development prospects are very broad, but the industry in the domestic media overheating, a large number of enterprises have invested in the production of LED industry. We also need to face it with a rational attitude, not only to see the bright future, but also to face the difficulties faced in its development.

American CREE company is installing LED lighting products inside the office, found with the traditional fluorescent lighting contrast, the 8 ceiling lamps using LED lighting, according to different environmental requirements of mediation of luminance value, energy consumption can be between 15 Watt ~42 watt self regulation, the average energy saving of up to 21%~71%. In the reception area the use of new energy-saving lamps to replace 26 ceiling lamps, each lamp 12 watts, the average energy saving of 77%. In addition, due to the long life of LED (50 thousand hours), greatly reducing the cost of product maintenance. In fact, these products do not contain mercury and other special treatment of harmful substances, will not damage the surrounding environment after retirement.

LED power up to the current production of 80 lumens per watt, which means that as long as a lamp using less than 100 star LED can replace the traditional lamp, use of long-life LED can reduce street maintenance depreciation expense; two times through the optical design of LED lamps, LED road lamp to reach IES (Association of lighting engineering the light intensity distribution in type II) standard in.

In the field of lighting, the application of LED will be its green energy-saving performance, as the third revolution after the fire and incandescent lamp.

Industrial scale needs to be improved

At present, the patent in the field of LED, especially white light patent is still concentrated in the hands of CREE, OSRAM, the world's five largest manufacturers. The main LED chip suppliers are also concentrated in these international manufacturers. The Japanese market is the largest Nichia, TG company's products, the North American market is undoubtedly the most visible CREE's products, while China's Taiwan region is the largest market for crystal. Some Taiwan packaging manufacturers, such as billion light, East Bay, mainly in the low-end market, they have some manufacturers authorized patents, currently subject to certain restrictions, exported to Japan, Europe and other places still are in danger of litigation.

Relatively speaking, the mainland manufacturers in China started late, although the government's support, the development is relatively fast, but the upper reaches of China's patent application is less, and the peripheral invention patents. Downstream application patent application amount is large, mostly utility model patents, with the further expansion of the chip and package capacity, more and more mainland enterprises to participate in international competition, will also face the problem of patent more, last year's bill 337 incident is a warning for mainland enterprises. Patent problem is a problem we have to face and solve.

Although China's LED technology developed rapidly, but compared with the international level, the scale is small, can not form a competitive advantage and brand effect. Currently, the mainland has more than a dozen epitaxial chip manufacturers have been equipped with MOCVD (metal organic chemical vapor deposition), the total number of inputs into more than 40 units. In 2008 there were about 150 MOCVD installed and put into use, but
