In 2011,output value of Shenzhen LED industry is about 700 billion yuan, an increase of 25.9% (accounting for about 35% of the LED industry output value, accounting for 50% of total output value in Guangdong Province ),  in the links of industry,it has formed a "chip - package - application - equipment - material - testing "a relatively complete industrial chain, the middle and lower reaches of advantage is more obvious, is the largest LED packaging base and application product development production base. LED packaging, display quality LED lighting products, production and exports topps in domestic. According to statistics, a total of about 1705 Shenzhen public agencies. In September of 2010, the city officially launched the Civic Center contract energy management pilot projects, to take full advantage of the company's assets and technological advantages, to achieve a win-win situation of government and energy service companies; Energy Management Contract energy saving pilots demonstration based on the development of the city's public agency contract energy management implementation details, and actively promote energy management contract, to simplify the approval process to encourage cooperation project. Shenzhen adhere to push actively and steadily promotes LED street light pilot, in order to study and promote the application to test. As of the end of 2011, the city's road LED street lights have been more than 23,000, especially the downtown area and the Science and Technology Park, High-tech Zone, two LED street lamp demonstration project, due to the construction field research and rational design, insisted more in the energy-saving effect is most obvious non-trunk Road to the implementation of good lighting quality, compared to the original street light energy saving rate over 50%. As of the end of 2011, the city lights will be approximately 305,000, with a total power of 65,000 kilowatts, about 260 million kWh of electricity per year, of which the number of the original SAR and Shenzhen North Station area road lights about 112,000pcs.
