LED general lighting applications will take time

With the improvement of luminous efficiency of LED, as a new light source, LED lighting has been touted in the world. In our country, in recent years the development of LED lighting is also under intense attention of the government and the investment and industry, a city become the semiconductor lighting industry base, many big city actively seeking to enter the Ministry of science and technology "ten city lights" plan. It can be said that China's LED lighting has entered an unprecedented period of development.

Seize the opportunity to actively promote the development of LED lighting

At present, China's LED lighting industry is facing a rare historical opportunity.

First, energy-saving emission reduction policy. In the global economy, more and more attention has been paid to low carbon economy, and the government of our country regards energy saving and emission reduction as an important principle in economic development. LED, low energy consumption, the energy consumption is reduced by 80% incandescent lantern light. In addition, LED does not contain harmful metal mercury, environmental pollution is very small. Therefore, LED lighting for energy-saving emission reduction significance.

Second, the economic recovery and stimulating domestic demand for new industrial growth point. In 2008, the global financial crisis has a great impact on the global economy. In order to get out of the crisis, the Chinese government has issued a series of industrial revitalization plan, and invested 4 trillion yuan to stimulate domestic demand. The leading role of the government in the economic recovery is very obvious, and it is the common concern of the government and the industry to cultivate new economic growth points with the potential of market and technology. LED belongs to the category of high technology, the future market prospects in the field of lighting is broad, it is estimated that if the high brightness LED to replace the traditional incandescent lamp, will reach more than $300 billion market size. Therefore, LED lighting has become a new growth point of the basic conditions.

Third, LED technological progress and industrial upgrading in recent years are very rapid development. In recent years, LED wafer, chip, package, drive circuit and display applications, lighting control and other related technology development is very fast, the price increase, which gives LED lighting from reality may bring infinite hope. At the same time, the Chinese government's investment in science and technology of LED is also increasing, LED has been supported by the national "863" plan, science and technology support program, LED basic technology research and development has a very rare opportunity for development.

Objective analysis to grasp the key points of LED lighting development

First of all, we must have a comprehensive understanding of the connotation of LED lighting. LED lighting covers a wide range of applications such as LED display, landscape lighting, backlighting, public lighting, special lighting and general lighting. There are many segments of the market, the industry also has different levels, there are obvious differences in product technology, LED application prospects. In the traditional LED display applications, full-color display market space is very large, a variety of display products market will continue to grow. In the field of lighting, decorative lights and street lamps as the representative of the special lighting applications, the rapid development of. Application in the field of general lighting, is the future direction of development, but it will take some time. Secondly, we should objectively analyze the actual technical level of LED in china. Taking the LED chip technology of the basic material as an example, the gap between China and the United States is obvious, especially in the high power products to meet the general lighting technology gap. However, domestic chip materials in display applications meet should be said to have a good foundation, two LED display the 60 anniversary of the new China established the National Day in Tiananmen square central location, using the domestic LED materials, good display effect. For LED lighting and application development, you can say: LED in the application has been mature and widespread, promote the development of a large space; application in special lighting field, rapid development in the field of general lighting applications just unfolding; started, the prospect of unlimited development, a long way to go.

Third, we must rational layout, steadily promote the development of LED lighting and priorities. I think, in the field of technology, should increase the support for material research and development, especially for the lighting of high-power chip technology to give priority to the development of. In the field of industry, we should pay attention to display the application of products, landscape lighting, public lighting and other markets. In fact, China's LED display application annual sales scale has more than 10 billion yuan, product technology to achieve the international advanced level, products and a certain scale of export. Global high brightness LED in automotive lighting, public signs and signal signs and architectural lighting applications more mature, the relevant application market size of nearly $10 billion.

Rational understanding of sustainable development and promote LED lighting development of LED lighting, especially in the field of general lighting, must have a rational understanding. At this stage, there are some possibilities, but not all of the possibilities, but do not represent the full reality.

LED as a new type of light source, the main performance advantage lies in its long-term energy saving and high reliability. LED as solid luminescent materials, service life of up to 80 thousand -10 million hours; LED is a low voltage and current, power supply voltage between 6-24V, than the use of high voltage power supply safety, more suitable for public places; LED light color is also very rich, through chemical modification, band structure and band gap adjustment materials the realization of red yellow and green Blue Curacao multi-color light emitting etc.. However, the current LED as the light source, the price is more expensive than incandescent lamps, LED light source price is several times the price of incandescent lamps, relatively high cost will restrict the LED light source in a certain period of popularization and
