LED street lighting is a major trend of road lighting

Analysis of domestic LED street lamp market scale

According to OFweek semiconductor lighting network estimates, with the global economic growth, the global street market will show a growing trend in 2011, the global market size of street lights up to 180 million to about 1.6.

Although the development speed of LED street lamp in 2009 is not expected, it will replace the traditional street lamp. Now a lot of LED companies competing to invest in R & D LED street lamps, there have been hundreds of LED street lamp products, but most have not achieved mass production. Compared with the enthusiasm of LED street lights, in 2009 China's LED street market has yet to force. According to statistics, in 2009 China's LED street lamp market size is only 20-30 million, in 2010 the annual Chinese LED street lamp market size of 120-130 million. The next few years, in ten city lights, one hundred thousand lights, Trinidad in 12th Five-Year national planning policy, China LED streetlight market still maintain a rapid pace of market development, is expected to 2012, the market size in 2008 will be 560 million yuan rose to 3 billion 960 million yuan, the compound annual growth rate of up to 63%.

The rapid development of China's urbanization and energy conservation and emission reduction efforts to increase, but also for the future development of LED street lamps provide a huge potential market. Over the past two years, LED street lamps continue to attract more manufacturers input. A veteran of the traditional lighting companies such as OSRAM, GE, Thorne, Shi Laide, sitko (Siteco), ZumtobEL, BEGA, Cooper, Hess etc. have been fully rolled out LED lamp R & D and production. The driving force of these initiatives is optimistic about the industry and continue to expand the LED street market.

According to the analysis of OFweek data in 2010, Chinese city street route length of 564506.2 kilometers (not including rural roads), street 18 million 237 thousand and 800, of which 10 million 598 thousand and 200 high pressure sodium lamp, accounted for 58.11%, energy-saving light source lamp 7 million 121 thousand and 800, accounting for 39.04%, 454 thousand and 600 high pressure mercury lamp, incandescent lamp accounted for 2.49%, 247 thousand and 900, accounting for 0.36%. due to high pressure sodium lamp use close to 50% is using huge exceed the standard, light pollution and energy consumption, and the proportion of high-pressure mercury lamp and incandescent lamp, a total of nearly 35% lights can be used to replace the LED lamp. On the other hand, the new rural construction and the construction of small towns also provide a broad space for the LED street lamp, and the market potential is very great.

Comparison between LED street lamp and traditional street lamp

The street light Market: high pressure sodium lamp, made for life quality and technical problems is relatively short, generally less than 3000 hours, imported with Philips best, reach 3000-4000 hours, monomer LED life of 80 thousand hours or more, the cluster into a large power LED, its service life is more than 60 thousand hours that is equal to the best of HPS in circulation today more than 15 times the life, that is, high pressure sodium lamp replacement more than 15 times, to replace a LED lamp, replacing the light source cost in living, and therefore the maintenance cost and the inconvenience caused is the most obvious comparison, street lamps for special purposes (for. Difficult to change, to spend a certain amount of manpower. Machine resources to complete the operation.

With the widespread use of high-power LED in lighting decoration and lighting, power LED driver is becoming more and more important. Road lighting using high-power LED lighting will become possible. Road lighting is the longest time and the largest consumption of lights, street lamps with LED lights will greatly reduce the city's power energy shortage, saving the national energy.

But instead of the traditional LED street lamps in the light source cost is not dominant, but in the laying cost, LED street has the light source can be used to save cost, save electricity is to bring their own income, and life benefits and disadvantages, the installation of road more cost savings more (the above does not include the pole, installation and maintenance costs, actually installed LED street lamp costs are far lower than that of the traditional street lamp installation costs).

Because the lamps are horizontal inserted type, made of single luminous LED manufacturing only, but only a positive position in the bulb tune, does not affect the light effect. The power of street light is divided into 20W, 30W, 40W, 50W with high power LED, long service life, maintenance free. Due to the low power consumption, low voltage and small current of the LED, the section of the cable is correspondingly reduced, and the installation cost is saved.

Traditional street lamps require a large power supply system. Large power transformers are very expensive. And the traditional lamp voltage can not be too large fluctuations, otherwise, will seriously affect the life of the lamp. The LED street lamp driver module does not require large transformers. This also saves the cost of LED street lamps.

Interpretation of the development of Guangdong LED street lamp

LED street in Guangdong Province, the strong momentum of development, as of the end of 2010, Guangdong Province, in the "ten city lights", "one hundred thousand miles" and green lighting demonstration city, LED street lamp demonstration project under the impetus of the installation of LED street lamps 200 thousand lanterns, demonstration sections more than 2000 km, forming the largest scale application of LED lights the. However, development is not a LED lamp Everything is going smoothly. resistance, unexpected. LED technology change rapidly, the highest LED lamps cost not under the contract energy management model (EMC) in the country to seek a new breakthrough to The climate does not suit one., innovation, more critical is because the LED street lamp products lack of detection means and uniform technical standards, product quality caused by uneven, disorderly market competition.

In order to solve the problem of street standard industry, Guangdong provincial science and technology department in the country to promote the use of LED product evaluation benchmarking system, and in the green lighting demonstration
