Lock LED City Urbanization "Blue Ocean"

The LED is a LED lighting Ⅲ - Ⅳ aromatic compounds, such as GaAs ( gallium arsenide ), GaP ( Gallium Phosphide ), GaAsP ( gallium phosphorus ) and other semiconductor formed 's . In the LED industry, in 2009 the consumption of the metal gallium is about 25 tons in 2010 to about 50 tons in 2011 will reach 75 tons , in 2012 exceeded 100 tons, together with the modern semiconductor industry ( wireless communications and LED lighting ) using amount accounts for about 80 percent of annual production of gallium metal . It is due to the development of downstream industries led LED demand for the metal gallium explosive growth .

China is experiencing an unprecedented rapid urbanization. According to Chinese Academy of Social Sciences in 2013 City Blue Book 2020, China 's urbanization rate expected to reach about 60%. The estimates show that by 2020 and 2030, the country needs to transfer the total agricultural population of people will reach 300 million and 390 million .

In fact, in the past 30 years , urbanization not only for black and white data , more expansion of city size , city life becomes more colorful , urban population continues to increase. Of course , there are many attendant negative effects , such as environmental pollution, traffic congestion, rising crime rates , and so on .

How to solve urbanization problems brought about changes in the process , become a subject of government, business , the public face together . In the twenty-first century, the largest urbanization process in China will be the world's emerging markets and Third World countries urbanization template. And China 's goal is to build a sustainable competitive with cities, it must contain livable , economic development, cultural tolerance and environmentally friendly , "urban " features such as convenient transportation and many other aspects .

Urbanization Opportunities

Urbanization will drive hundreds of millions of peasants into the cities , forming China 's emerging consumer groups. Gradually release their consumption potential , will become the new engine of China's economic growth. Rapid urbanization promote social progress and economic development, but also many challenges associated with the urban environment , infrastructure, management and other aspects ; and this one, the city's energy consumption is especially noteworthy.

Urbanization process, the innovative LED lighting technology apparently got the biggest development, but it has also become a time to solve the problems of urbanization , a particularly critical technology.

LED light-emitting diode , compared to traditional incandescent, halogen , fluorescent lamps, sodium lamps, high intensity discharge lamps and other lighting products , which is the best currently available energy-saving lighting products , power consumption of only ordinary incandescent ten one points. Currently, lighting accounts for about 20% of the world's total energy consumption energy consumption. As the world's energy consumption big country, China's energy consumption per year on lighting huge . According to professional statistics, if 50% of the Chinese lighting system replaced with LED, then the annual savings in electricity can build 2.5 Three Gorges Power Station .

In addition , LED as well as a prominent feature is a very long life , energy saving lamp life in general from 6000 to 8000 hours , while the life expectancy of LED lighting products under normal conditions up to tens of thousands of hours. LED long life make the use of cost , compared with the original urban lighting has a huge cost advantage.

Secretary-General of Shanghai Municipal Lighting Industry Association Wengyin Fu said in an interview , whether incandescent, fluorescent or LED lights , electricity costs account for over 60% of the overall cost of the LED lamps have very high luminous efficiency, low energy consumption , and therefore the long term point of view , the use of LED lighting integrated the lowest cost, as of 2012 , the overall cost is less than 25% of incandescent lamps (LED production scale continues to lead to lower costs in ) .

On the one hand because of the huge advantages of LED , but also benefited from the global pace of urbanization is accelerating , according to the forecast 2020 global LED lighting output value will reach $ 65.8 billion . According to reports China Taiwan Industrial Technology Research Institute Industrial Economics & Research Center , Greater China LED market reached $ 6.9 billion in 2012 , can be expected in 2015 , will reach $ 11.1 billion , a CAGR of over 20 %.

Create Livable Cities

Modern urban lighting is seeking a visual harmony , so that residents feel the harmony of light because it involves a series of questions the intensity of light , color , light the way , such as the principle of projection . LED lighting to meet this demand, its brightness and color temperature control, made ​​into lamps variety, which are so "light " content is greatly enriched .

Smart and energy efficient LED lighting solutions can not only enhance the residents a sense of security in the city streets , improve the quality of life of the people of the city , but also to enhance the personality and charm of a city , and promote the development of its business and tourism . Guangzhou landmark building , the world's highest TV Tower - Guangzhou TV Tower ( also known as the " waistline " ) , for example, during the Asian Games in Guangzhou in 2010 , the tower became a colorful Guangzhou Guangzhou skyline of the most beautiful scenery , but also to get the charm of Guangzhou Asian countries enjoy the show in front of the guests , and now she has become the tourists will go to Guangzhou tourist attractions and landmarks.

Guangzhou Tower bright colors and vivid results from more than 6,000 sets of LED lighting, almost nearly 330,000 LED pure particles can exhibit one million infinite changing colors. LED technology also allows the use of large-scale landscape lighting project that greatly reduces operating costs, a rough estimate, the power consumption of 500 kilowatts an hour , less than 1,000 yuan, more than twice as energy-efficient than traditional lighting solutions .

In addition to illuminate the outside , LED intelligent innovative applications also realized the intelligent control of lighting , traditional lighting and lighting unit for each two-way communication , making it impossible to monitor their fine work and can not according to the surrounding environment ( depending on the weather , flow and other changes ) to adjust the lighting to give , but the innovative use of LED lighting management allows the city to become more intelligent , such as traffic rarely midnight , road lighting brightness may rush hour would be quite different. LED intelligent control highlights the advantages of unparalleled innovation , technology and innovation demonstrates the tremendous power to change the living environment .

This will be a combination of LED and Internet innovation and technology , will make the vision of the first things to achieve in the lighting field , through light and dark or light color controls make lighting environment for people to work, study , and provide a better life healthier intelligence services. Meanwhile innovative intelligent lighting system also has a platform for the exchange of information and feedback , so that people in a relaxed environment while enjoying the lighting , lighting applications can communicate with each other on the platform control information.

LED intelligent application of innovative focus on expanding the whole society saving , saving, saving intelligent lighting concept . Lighting Research Institute of Fudan University , Professor Chen Dahua , said in an interview , intelligent , networked LED lighting will become the trend of the future , but for the city manager , this " intelligent" city management will bring light pole great convenience. Today, the rapid development of LED technology , not only to meet the needs of the lighting , but also help cities reduce energy consumption, reduce urban operating costs. On this basis , the intelligent lighting solutions will further , not only can automatically control lighting system , but also through the innovative application of interactive data , connectivity and other technologies will be the city's public lighting system access "Energy Internet" , thus achieve urban management information, intelligence , improve operational efficiency of the entire city management system.
