Dou Linping: do not blindly invest in LED lamps

Dou Linping, Deputy Secretary General of China Lighting Association

"Fireworks in March in Yangzhou, jointly organized Chinese Lighting Appliance Association, China Institute of lighting outdoor lighting Specialized Committee, Chinese Municipal Engineering Association of road lighting Specialized Committee" 2008 Chinese Road Lighting Forum "held in the beautiful Yangzhou in mid March. There are people including manufacturers, industry experts, scholars, colleges and universities in the provinces or the municipal road management office of more than and 400 people attending the meeting. Delegates rewarding, we believe that the forum for production, learning and research to build a platform for the exchange, delegates through the forum has research and development, production and use of the road lamps in the problems are discussed deeply and widely, the production enterprise and user unit technology, development trend, on the road lighting using situation a comprehensive understanding of. But tend to appear in the forum can make the people have deep feelings, to speak out.

The theme of this forum is "road lighting energy-saving technology implementation. Road lighting in the process of using the method have much in the way of energy saving road lamp itself, including the reflector design, the use of electrical appliances, the choice of materials, lighting production enterprises have a lot of work to do. But in the forum process whether manufacturers or experts and scholars, using units discussed are LED to application in road lighting, the forum in the 28 production companies in places will show the product is clear LED color lamp. LED currently in the field of domestic lighting heat is high, which can be seen. It is said that the image of the "2008 China Road Lighting Forum" is the "LED road lighting forum".

Forum on the current use of LED lighting in the road there are two views, these two views in the forum had a fierce collision. One view (experts mostly), LED is currently on the luminous efficiency, color temperature and high pressure sodium lamp than there is a big gap, as decorative lighting and lighting environment with no problems, such as road lighting, currently only suitable for school (Park) district road or road, but the road lighting as the main function (main road) there are many technical problems to be solved (such as temperature, light distribution uniformity, two), it is not appropriate to road lighting. One who holds this opinion, does not deny the future with the development of LED technology, the application of LE D in road lighting; another view (enterprises), the optical efficiency of LED was lower than the high pressure sodium lamp, but effective light, as road lighting light requirements have been enough, and the color temperature is only a matter of habit. In addition, the enterprise that has passed the LED front end foreign patent monopoly, the LED road lamp research and development of domestic enterprises to go in front, not road lamps by foreign enterprises to the phenomenon of patent. The collision of the two views, so that the representatives of the participants, especially the user unit, the current situation of the LED road lamps have a comprehensive understanding of.

In my opinion, LED as a new type of energy-saving light source is very suitable for China's long-term national policy of energy conservation and emission reduction. But at present, the LED light source is still in the development stage, and many of its technical problems remain to be solved. As a lighting production enterprises to pay attention to the development of LED light source, according to the technical level of the LED light source, scientific, reasonable, timely development and production and LED luminous characteristics match the lamps, do not blindly invest. A real phenomenon is able to explain the problem, is the home of hundreds of existing lighting production enterprises in the development and production of LED road lamps, and everyone in the city to see how many roads in the use of LED road lamps? Although the use of some roads LED lamps, but the current comprehensive reflection is not ideal. Production enterprises should not only focus on LED road lamps, at this stage, many indoor lighting can use LED lamps, but the enterprises in this aspect of the time and invested capital is far lower than that of road lamps.
