With 10 city 10 000 semiconductor lighting project started, and on increasing energy requirements of environmental protection, China has basically established to LED outdoor lighting as the main direction. Including, LED lights of attention by the government as the market introduction of important entry points for lighting applications. In the LED chip and packaging technology continues to advance under, LED lighting has become the protagonist. More and more countries are developing carbon reduction regulations and lighting standards, which will not only help the development of LED lighting application markets, also means that LED lights will quickly look into the road to dominate the field of innovative lighting technology. LED lights will provide strong environmental protection, reliability, energy efficiency and aesthetic design features easy to become the new darling of the road lighting market, to the Chinese revolution in lighting industry upgrading and new opportunities.

LED lights of the domestic market

It is estimated that, as global economic growth, the global street markets year by year growth trend will arise in 2010, the global street market size is about 1.6 to 180,000,000.

LED street lamps in 2009 although the rate of growth faster than expected, but it will replace the traditional lamps, it is beyond doubt. Now many companies are rushing to power LED street light LED R & D, hundreds of LED lamp products have been introduced, but most do not mass production. LED lights compared to the enthusiasm of enterprises in 2009, China's LED Lighting Market forces have not yet issued. According to statistics, in 2009 China's LED Lighting market is only 20-30 10 000, the next few years, the 10 city 10 000, Trinidad 100 000 and other policies to promote the slogan, China LED street lamp market, the market remains relatively fast growth rate, 2012, the market size will be 5.6 billion yuan in 2008 to 3.96 billion yuan, the annual compound growth rate of 63.0%.

LED lamps cost competitive advantage

Although still higher than the high-pressure sodium lamp LED lamp 3 times expensive, but the integrated power and maintenance cost factors, after 2 years in use, LED lamps and high pressure sodium lamp is almost equal to the total cost. Therefore, in the long run, LED lights use the cost will be superior to the current high-pressure sodium lamp. 8-m high-pressure sodium lamps with LED lights compare, high pressure sodium lamps of 250 watts power consumption is about to be, LED only 60 watts, some in life, an average of about 4,000 hours of high-pressure sodium lamp, but the LED up to 50,000 hours. With the declining price of LED lights, its competitive advantage will become increasingly evident. 

LED street lamp light use efficiency

LED luminous efficiency. Currently available to the procurement efficiency LED light has reached 100lm / W, the luminous efficiency much higher than the energy-saving lamps, metal halide and electrodeless lamp, street lighting than is currently widely used in high-pressure sodium lamp is much higher than 10%. Therefore, LED light has now become one of the most efficient light sources. Replace incandescent lamps with LED, fluorescent, metal halide and high pressure sodium light source is no longer any major technical obstacles, just a matter of time.

Technical problems in the development of LED lamps

With the LED lighting market in blow-market, LED streetlight development becomes clearer.

Public enterprises have a beachhead LED lamp market situation out of control. Although the LED industry has developed rapidly in recent years, but still lack the authority of the technical standards, leading the industry in different ways, to the promotion of a wide range of very unfavorable. Relatively high in the technical difficulty of LED lights, the problems caused by lack of technical standards in particular. Many excellent LED technology manufacturers and integrators, and do not know how to design a practical street, unable to clarify the application of sector specific requirements. For example, many manufacturers of LED heat to solve the problem, design a "hollow-type" lamp. But on the street for such a model, "shelter" feature poor, is not suitable for street lamps.
