Joint production and government, Tianjin to build China's first LED city lighting demonstration zone

Due to the advantages of energy saving and environmental protection, LED semiconductor lighting has become the focus of attention of the academic circles around the world. At the end of 2, Tianjin Economic Development Zone (TEDA) announced plans to join the LED City, becoming China's first LED city lighting demonstration zone. TEDA and CREE (CREE), Tianjin University of Technology, semiconductor lighting engineering research and development center to further explore and promote LED lighting applications, and promote the development of Tianjin semiconductor lighting industry.

With the improvement of luminous efficiency and cost reduction, LED is being extended from backlight applications to general lighting. However, due to the high cost and social awareness is not high, the current LED lighting is still in the early stages of development. In order to promote LED lighting, the well-known LED chip maker Cree has proposed a global aims to establish LED city lighting demonstration area of green lighting LED City action plan, by the local government and LED manufacturers to jointly promote in all municipal infrastructure in the promotion and deployment of LED lighting technology, in order to save energy, protect the environment and reduce maintenance costs and improve the quality of lighting, and public education.

LED City plans to actively explore and promote LED lighting applications.

Cree company vice president of marketing Chris James said: we are very pleased to be able to become a participant in the city of LED lighting TEDA, China's first to start LED city lighting demonstration zone. We encourage other Chinese cities and universities to join the ranks of LED lighting to help reduce the world's energy consumption, and through innovative design and production, in order to speed up the application of this new technology in china. "

James said that since the LED City program was launched in February 2007, has been in North Carolina, Rowley City, Toronto city in Canada and the U.S. state of Michigan has announced to join Arne Bohr, LED for parking and other public lighting lamps. For example, Arne Boer city will be installed in the next two years more than 1 thousand LED street lights, is expected to save energy by 50%, only 3.8 years to recover the initial investment. The city promised, once the technical and economic conditions permit, in the indoor and outdoor all use LED lighting. Full implementation of LED lighting is expected to reduce the city's public lighting energy consumption, reducing greenhouse gas emissions by 2425 tons per year. Local power companies will use meters to measure the new LED street lights, in order to collect enough information to develop a new LED based price list.

Deputy director TEDA Ai Yamin said that in 2007 the semiconductor lighting is used as one of the 20 key development projects in Tianjin City, TEDA will fully support the promotion and application of semiconductor lighting engineering, semiconductor lighting industry bigger and stronger support. To this end, TEDA plans to build two platforms, is a platform for the transformation of semiconductor research and achievements, including the combination of Government R & D Center University of Tianjin semiconductor lighting and LED Lighting City demonstration area; two is the industrial base to form a semiconductor lighting.

Chinese Lighting Appliance Association chairman Chen Yansheng believes that in recent years, LED lighting applications in the country set off a climax, but there are still some blindness, because the LED technology is still in a development process, TEDA hope to explore the application of LED lighting is scientific and reasonable, and truly become a LED lighting demonstration area.

As the contractor of the LED urban lighting demonstration area, Tianjin semiconductor lighting research and development center has accumulated rich experience. Dr. Niu Pingjuan professor of the center said that since 2002 began LED technology development, including the application of upstream and downstream of the epitaxial technology development of two parts, from the beginning of 2006 is strong in technology development and application LED lighting, walk in the forefront of the domestic. In the past two years, the Tianjin Polytechnic University new campus design, production and installation of about 1500 LED street in the center, about 2000 LED lamp installed in eight dormitory building, more than an annual saving of hundreds of thousands of.

Niu Pingjuan said, the second half of 2007 LED lighting upstream technology has a great breakthrough, such as PHILPS and Cree manufacturers launched more than 100 lumens / watt LED light source, LED light source with special advantages, making the overall optical efficiency of LED lamp is greatly improved compared with the traditional products, and promote the application of LED lighting. She pointed out: LED lamps have begun to enter a wide range of indoor and outdoor lighting and other fields, but there is no large-scale start, mainly because of national standards and cost issues. "

At present, the detailed planning of Tianjin LED urban lighting demonstration area project has not yet been announced. Ai Yamin admits, TEDA held the ceremony, is the first to show an attitude; secondly, the development of technology needs a process, the current LED lighting and light emitting efficiency and cost problems, so can not start at all costs, but to go step by step. Currently part of the TEDA has been in the trial of LED lighting, the future development rate depends on the actual situation of the budget and product price cuts.
