In the evening, the new campus of Tianjin University of Technology in Xiqing District was at the beginning of the Hua Deng, and the soft lights left the students busy on the road. In a quiet campus, perhaps no one is aware that these street lights are not ordinary. In fact, the campus is currently the largest LED lighting demonstration project in the world. It is distributed in 1,500-inch LED street lamps and 5000-inch LED indoor lamps on roads, lawns and school buildings, and contributes to energy conservation, environmental protection and environmental protection day and night. It will also light up the future of the lighting industry.
The LED ??? decryption is continuously lit for 100,000 hours. The street lamp has a large street lamp. It is a familiar facility in life, but with the LED on the front, it seems that there is a sense of distance. The small thing made up of light-emitting diodes, the heart is a semiconductor wafer that converts electricity directly into light. At present, LED street lights with small volume consumption, long life, high brightness, low heat and environmental protection have triggered a lighting revolution.
Professor Niu Pingjuan, director of the Semiconductor Lighting Engineering R&D Center of Tianjin Polytechnic University, said that energy-saving lamps are 4/5 more energy-efficient than incandescent lamps, and LED lamps, which are recognized as one of the most promising high-tech products in the 21st century, are more economical than energy-saving lamps. 1/4, can work continuously for more than 100,000 hours, almost no maintenance. “LED street lamps are about 50% more energy efficient than traditional street lamps, with a total photoelectric efficiency of more than 85%, and lifespan is five times that of traditional street lamps.†Niu Pingjuan said, “Replacing traditional street lamps with LED street lamps can greatly reduce the gas pollution generated by street lamps and improve them. Urban air quality. LED street lights are cold light sources that do not generate high temperatures during use like traditional street lights, which reduces heat loss. In addition, LED street lights do not contain harmful substances such as mercury and lead in ordinary energy-saving lamps."
LED??? Accountant Daxin Campus One year of power saving 1.8 million degrees in the new campus of Tianjin Polytechnic University, lawns, benches, dormitories ... everywhere shines with LED lights. “These lamps are all developed by the school's semiconductor lighting engineering R&D center. We have recently added 3000 ç› indoor lights, and now there are 5000 。. According to one year, the LED lights in the new campus of the University of Technology can save 180% compared with the previous lamps. Ten thousand meters of electricity, equivalent to nearly 700 households a year of electricity consumption." Professor Niu calculated an account: Assume that 30% of global users switch to energy-efficient lighting products, preliminary calculations can reduce 260 million tons of carbon dioxide emissions and 4600 Electricity consumption is tens of kilowatt-hours, which is equivalent to one-fourth of India's annual electricity consumption or China's annual electricity consumption. According to the “Ten Cities and Ten Thousand Miles†plan, by 2010, China will promote more than 300,000 LED municipal lighting fixtures in 10 to 20 cities. From 2005 to 2015, it is estimated that China's semiconductor lighting can save 400 billion kWh of energy, save users 260 billion yuan in electricity bills, create 150 billion yuan in output value, and solve the employment of 1 million people. After 2015, the annual energy saved by China's semiconductor lighting will exceed the annual power generation of the Three Gorges Power Station.
A number of residential communities such as Binhai High-tech Zone, Dongli Development Zone and Style Spring have successively launched LED lighting demonstration projects this year, marking the launch of the “Ten Cities and Ten Thousand†semiconductor lighting application engineering pilot project in this city. It is understood that at present, the city's new, updated and rebuilt landscape lighting will use LED lights. It is expected that there will be more than 50,000 LED lights with low power, low power consumption, uniform illumination and good environmental protection during the year. After a year of testing, LED lights will be used more widely than the traditional high-pressure sodium street lamps. According to the "Tianjin Semiconductor Lighting Application Engineering Implementation Plan", the city plans to use the LED Grand Canal, LED Campus, LED Eco-City, LED Industrial Park, LED Transportation and other five sectors to promote the application of LED lighting 500,000 in stages.ç› Above. By 2012, Tianjin LED Application Demonstration Project can realize annual energy saving of 250 million kWh and save electricity costs by about 200 million yuan, equivalent to saving 100,000 tons of raw coal, 1 billion liters of water, and emitting 70,000 tons of carbon powder and 250,000 tons. Carbon dioxide, 0.8 million tons of sulfur dioxide, 0.4 million tons of carbon oxides, and the like. By 2015, the city will promote the use of 2 million LED street lights to save 1 billion kWh of electricity and save 800 million yuan in electricity bills.
Professor Niu said: "We have successfully developed the first domestic LED car headlights jointly with several enterprises and institutions, including low beam, high beam, position light and turn signal made with high brightness light source, and got the national 863. Support for the plan. On this basis, the center submitted the national standard for LED car headlights."
LED status quo The city's industrialization company produces 300,000 baht per year. "LEDs have the characteristics of energy saving, environmental protection and durability. For China, which is increasingly affected by energy shortage, there is a broad space for development." Professor Niu said that “Recently, the Engineering Research Center of the Ministry of Education of High-power Semiconductor Lighting was listed at Tianjin Polytechnic University, which means that an innovation mechanism of production, education and research integrating R&D, engineering and industrialization has gradually taken shape.†It is understood that the development center has joined the city. 61 enterprises and institutions set up Tianjin Semiconductor Lighting Engineering R&D and Industry Alliance, initially completed the research and development and industrial layout of LED upstream and downstream, and increased the research and development of LED key materials and terminal products.
At present, Tianjin University of Technology has established an industrialization company, Tianjin Gonghaiyu Semiconductor Lighting Co., Ltd., to implement the industrialization of semiconductor general lighting fixtures, and has formed a production capacity of 300,000 high-end LED lighting products per year. In 2008, the company applied for 42 patents, including 8 invention patents. The products are used in many demonstration projects in China and exported to the United States, Europe, India and other places. Due to the strong advantages of LED lighting, in addition to the use of street lights, tunnels, subway cars, platforms, parking stations, large-scale activities, etc. also have a large demand.
LED??? Promote domestic lighting market share
20% in 2015
It is understood that the high cost of LED is the bottleneck of its development, and it is currently unable to be widely used in the civilian market. At the same time, although China's LED lighting industry is one of the few high-tech industries with little difference from developed countries, it is still 3 to 5 years behind the international advanced level, the main core technology of LED lighting and more than 90% of upstream resources. They are all controlled by the three giants of General Electric, Philips and Osram. Niu Pingjuan said: "All people collect firewood and have high flames. To solve the problem of LED technology, while strengthening independent innovation, we must also take advantage of the advantages of combining with enterprises, and build on the foundation of the engineering center to break through the bottleneck."
According to the National Semiconductor Lighting Engineering R&D and Industry Alliance, the LED lighting penetration rate will reach 20% of the domestic lighting market in 2015. It can be seen that the LED market is promising. For the future of this new lighting industry, Professor Niu is concise and succinct as “a lot of hope and great hopeâ€. She said: “With the improvement of the semiconductor lighting industry chain in this city, the industrial layout has been completed, and the agglomeration effect has become increasingly prominent. Tianjin has become a domestic The regional semiconductor lighting industry chain has one of the most complete LED industry chain regions. At the same time, the city has basically formed a relatively complete industrial chain integrating substrate materials, epitaxial wafer manufacturing, chip production, device packaging and LED application. System. The application of LED technology in the world is the trend of the times. With the continuous improvement and development, its future is also bright."
