The whole city for LED street lamp? Think, but not too dare!

LED chip lit hundreds of millions of stars of landscape lighting, Shanghai gave World Expo the more the more beautiful night. Completion of the world's largest semiconductor lighting technology demonstration application in Expo Park, opened the light and shadow of the world's first semiconductor". Over the past year, the Expo through the LED light source to light up the lives of the people? From today's closing of the Sixth China International LED luminous body and urban lighting exhibition was informed that the streets have been more than a thousand 23000 LED street lamps, compared with nearly 500 thousand of the huge light group, but small-scale pilot. Industry experts believe that the bright LED lights want to illuminate the road all the way to Shanghai, there is a long way to go.

Industry is very bright street lamp is difficult to shine

More than 3 thousand semiconductor lighting (LED) enterprises, 13 semiconductor lighting industrial base...... Shanghai semiconductor lighting Engineering Research Center released the latest industry report, in 2010 the scale of China's semiconductor lighting industry reached 120 billion yuan. Another set of data also show that in 2010 China's LED industry contracted program total investment of 217 billion 800 million yuan, as of the end of 2010, the new project has been completed the actual investment amount of 34 billion 300 million yuan. In the first year of semiconductor lighting, the scale of China's LED industry has expanded rapidly, and the development environment has improved significantly.

However, the city's large lighting - Road, elevated, high-speed street lights, the response is slow". In fact, LED street in Shanghai is a minor, the major part of the Yangtze River Tunnel Bridge Road and Wuning Road, and road sections, and some small road, 1000 of the total number of light, relative to the total is very rare.

It is reported that Shanghai has completed the development of rail transportation vehicles and platform height lighting system and its large-scale application, the development and application of elevated road lighting lamps and other research projects. Yanan east road tunnel, the upper and middle reaches of the tunnel and part of the subway station and the car to complete the LED lighting program evaluation, the specific implementation steps and time is still repeated.

Hope the policy in place lit LED street lamp

At present, the city street lamps for energy saving and environmental protection LED lighting but do not dare to use. Shanghai Street Management Center Engineer Wang Xiaoming explained that the state has no corresponding production standards for the LED light source, who will check the technology, product quality, how to verify it? In order to ensure the traffic safety, metropolis city lighting system with lighting rate strictly, streetlight system could not risk being light".

After decades of technology accumulation, the existing failure rate is about 3%. LED street light is the result of the experiment, the failure rate of up to 10% to 20%, if the whole city for lights, engineering and technical personnel to climb the ladder every day to replace the bulb. At the same time, a large number of Shanghai street, can not be swept by an enterprise, between the manufacturers product technical standards are not unified, even the lamp size, approved the basic technical parameters of power are not the same, not compatible, difficult to comply with the city lights to seek a unified and efficient management.

These problems cannot be solved by the LED production enterprises themselves, to state the introduction of regulatory policies to give guidance, make clear and feasible production standards, improve the production quality, unified product specifications among enterprises, clear quality assurance and customer service service standards. Thus, the spread of the city street lights to early 'green' up. Wang Xiaoming said.
