LED city lighting market hot customer awareness needs to be strengthened

At present, LED (light emitting diode) lighting technology matures, high power LED light source efficiency has reached 80lm/W, energy-saving city street lighting possible, LED light source used in road lighting has become a hot topic in the semiconductor lighting industry in recent years. At present, there are more than 100 enterprises at home and abroad have been put into the development of semiconductor street lamp, but have not been put into mass production. In addition to the reasons for the technology to be exceeded, the high installation costs and the absence of product standards become a major factor restricting the large-scale application of LED street lamps.

Market has already started

World famous LED manufacturer CREE (CREE) company initiated LEDCity (LED city) project started in February 2007, July 2007, the Toronto commercial development of Canadian Association for the promotion of Toronto announced plans to join LEDCity, and in many lighting application evaluation, deployment and promotion of the use of LED. In October 2007, Michigan's AnnArbor became the third LEDCity. AnnArbor will install more than 1 thousand LED street lights over the next two years. Since the launch of the plan, cities around the world have expressed interest in joining the LEDCity program. Recently, the Tianjin economic and Technological Development Zone and CREE cooperation, so that Tianjin has become China's first LED city lighting demonstration zone.

According to Professor Dr. Niu Pingjuan semiconductor research and development center of Tianjin University of Technology, in the past two years, Tianjin University of Technology semiconductor lighting R & D center in the design, production and installation of the new campus of Tianjin University of Technology was about 2000 LED lights, mainly used for indoor lighting, school and student dormitory corridor lighting, the new campus of the 15 kilometers of all lights LED light source. "LED technology is the latest development of the lighting industry to save energy and reduce costs. We are very pleased to work with CREE and join the international LED city lighting project. Niu Pingjuan said.

According to the U.S. Department of energy data show that the United States in 2006 22% of the electricity used for lighting. At present, rising energy prices, environmental sustainability concerns are growing, innovative lighting technology has long been of concern.

The general manager of Shanghai Blaupunkt photoelectric materials company Liang Bingwen in an "China electronic newspaper" interview with reporters stressed that China is currently one of the world's fastest urbanization of city country, can be expected in the next few decades, the country is huge for high power, high brightness, energy saving LED lamp the product market demand.

Municipal street market statistics show that China's city road lighting a total of 15 million above the street, in recent years, the growth rate of over 20%, according to this estimate, the annual national street lighting market size of not less than 5 billion yuan. If you do not belong to the street lights at all levels of management, such as factories and mines, organs and institutions, such as residential street lamps, including the calculation, the number is even greater. Plus other incandescent and fluorescent lighting, the total in 90 million or more, if all replaced LED lighting products, the annual savings of electricity resources more than 100 billion kwh, equivalent to the full capacity of the annual generating capacity of the Three Gorges project.

According to Chinese Institute of semiconductor director Li Jinmin introduction, LED lamp from the global situation, in 2005, Philips (PHILPS) in Holland installed the world's first LED street, Lincoln City, then the British Toronto Canada and the United States North Carolina, Raleigh LED city construction of city road lighting. Through the demonstration, the residents of the city for the LED of lighting quality recognition is greatly improved, taking Toronto as an example, the city of about 160 thousand street lamps, if it all changed to LED street, is expected to save $600 million per year of electricity expenses and reduce 18 thousand tons of greenhouse gas emissions, equivalent to about 3600 cars from the street disappeared.

Breakthrough price and standard bottleneck

Technology progress and market application are complementary.

Semiconductor lighting is bound to be adopted in the industry, transportation, municipal and other special lighting industry should be used to drive the first. The street is the largest application market, used in street on the market if the government can give support to the development to a certain stage and then according to the rules of the market, may be faster to promote the rapid development of China's semiconductor lighting. Shanghai Sansi Technology Development Co. Ltd. General Manager Cheng Deshi believes that from the economic considerations, in certain areas if the integrated power substation, transmission, cable laying, lighting and electricity and other factors, LED and solar energy program may have become more economical choice.

The general manager of Shanghai Blaupunkt photoelectric materials company Liang Bingwen believes that there are three main factors affecting the popularization and application of street lamp: first of all, the LED lamp exaggerated publicity and the actual application is great, which affects the confidence of users in a certain extent. Inferior product promotion have a negative impact on the market, shoddy products LED seriously disrupt the market, causing authorities reliability skeptical of the LED. Secondly, the price is still an important factor that led to the current semiconductor street lamps can not be extended. High power LED street lamp for the first time the cost of purchase is higher, about 2-3 times of the traditional street lamp, which is used as a road lighting products LED market applications bring pressure. Third, LED road lighting product standards, color rendering index of high pressure sodium lamp illumination standard is not suitable for LED light source, the need for LED light source street lamps to develop the corresponding road lighting design standards. It is gratifying that the semiconductor lighting industry alliance recently launched LED street lamp technical specifications
