LED street market situation to stimulate market demand (Figure)

Human is indeed higher life wise, the ancient ape Zuanmuquhuo to modern people invented the electric light, light, no longer belong to the nature of the day; LED lighting lamp from the carbonized cotton thread of Edison to modern lighting industry in twenty-first Century, the human has entered a peak period.

LED street lighting market

With economic development, reducing the earth's resources, energy saving and environmental protection has gradually become a kind of attitude of people's life, and in a series of products of lighting, LED lighting has become a series of energy saving and environmental protection ambassador. First of all, LED low power, less power consumption, energy saving and environmental protection in line with the country to promote the policy; secondly, LED products and other products is more humane, it is used as the light source does not produce radiation, will not give people the feeling of dazzling, soft light, make people feel comfortable; again, LED has strong stability, after a long time not to weaken the luminous effect. It is because LED has more advantages over other lighting products, LED lighting market has the prospect and huge potential market, now the application scope of LED lighting products is very wide, Home Furnishing lighting, outdoor lighting, landscape lighting, stadium lighting, road lighting and so on, which benefits for many businesses, all great temptation.

The current situation of the development of LED lighting market

LED is called the fourth generation light source, because it has the characteristics of energy saving, environmental protection, long life, small volume and so on, in accordance with the requirements of energy-saving and environmental protection, so it has been widely used in various lighting field. In recent years, countries around the world in the research and application of LED launched a fierce technical competition. The United States since 2000 to invest $500 million to implement the national semiconductor lighting program, the European Union in July 2000 announced the launch of a similar plan. With the support of the "863" program, China first proposed the development of semiconductor lighting program in June 2003. ISuppli predicts that the overall LED market turnover will grow by about 13.7% in 2007, with a CAGR of approximately 2006-2012 in the year of, to $12 billion 300 million by 2012.

In many LED lighting products, among which the LED street lamp market most fiery, according to LEDinside research data show that in 2009 the number of global LED lamp device is about 610 thousand light, estimated the number of unit in 2010 of about 870 thousand street LED street; 2009 China area LED street lamp number about 250 thousand light, estimated to 2010 Chinese LED lighting market will grow 60% to reach 400 thousand or more scale, each enterprise planning can provide LED street lamp production capacity has far exceeded the market demand of the times. Why is the development of LED street lights so fast, the original, compared with the conventional high-pressure sodium lamp street lamp, LED street lights can be directly converted into light energy, with many advantages of traditional street lights do not have. For example, LED lamp itself has the directivity of light, no light diffusion, ensure the light effect, and the overall light efficiency than high-pressure sodium lamp; the second is the LED street light color is better than high voltage sodium lamp and LED lamp can be high; automatic dimming can meet the lighting requirements at different times, reduce the maximum possible power and save energy; again, LED is a low voltage DC voltage driving device, single LED safe voltage, so it is safer than the use of high voltage power supply, especially suitable for public places; in addition LED lights long service life, convenient installation, reliable quality; the most noteworthy point is that the LED light source, does not contain harmful metal mercury, unlike the high-pressure sodium lamp or metal halide lamps to harm the environment in scrap.

Out of the ordinary LED lamp lighting market has also been favored. In April 2009, the Ministry of science and technology "ten city lights" project officially started, with three years of time in the 21 pilot city to install millions of light semiconductor lighting products, the opening of China's large-scale use of LED street lamp to replace the traditional lamp off. According to the LED Engineering Research Center of high industry statistics (LIRC), in 2009 the country installed 222 thousand LED street lamps, is expected to 2009-2011 LED street lamps installed capacity will reach 1 million 120 thousand. While the other is still in the pilot phase of the project is expected to be in 2010 to 2011 large-scale spread. In addition to our country to promote the LED street lamp, the world's lighting industry giant - Ge, PHILPS, Rahm also have to cooperate with semiconductor companies, the establishment of lighting companies.

Factors restricting the development of LED street lamp

LED lamp heat makes our LED lighting enterprises such as bamboo shoots after a spring rain like pulling up public information, one is the LED lighting industry related enterprises have more than 3 thousand, including the application of more than 2000 enterprises, packaging enterprises on the scale of about 600, epitaxy and chip has 42 enterprises, but overall. Although the number is numerous, generally small scale.

This year, in order to further contact LED street market, a lot of enterprises engaged in the production and development of LED lights, but the quality is uneven, most of the enterprises by financial and technical limitations, the product design has not been rigorously optical, electrical and thermal aspects of professional, or quality requirements for the road the lighting and light distribution are not quite understand the concept or directly copying others, or by any combination of subjective imagination, arrangement and so on, so many problems are brought in the test and application effect. Now the general existence problem of LED light source on the market decline, some manufacturers LED lamp installation in less than a year the brightness attenuation phenomenon. LED lights can be converted into light and heat energy to work in power, component temperature increase of 2 degrees, the reliability of LED lamps will drop by 10%, when the working temperature from 63 degrees up to 74 degrees, the average life expectancy of LED will be reduced by 3/4, chip packaging, lighting
