Liu Lei: street lighting is not limited to LED street lights

Abstract: PHILPS lighting held in January 8th "harmonious city in Nanjing, and the future" seminar, Chinese lighting society vice president, Chinese Institute of lighting outdoor lighting Specialized Committee Zhao Jianping and Nanjing Nanjing City Street Management Office Deputy Chief Engineer Liu Leishi proposed energy-saving lamps do not necessarily focus on LED street.

At present in the domestic street lamp system LED lamp is very high: Shanghai to introduce 20 thousand, Changzhou to introduce 15 thousand ~ 20 thousand. Propaganda said LED lamp purchase costs, although higher than ordinary lamps, but can save money.

PHILPS lighting held in January 8th "harmonious city in Nanjing, and the future" seminar invited Nanjing city management office staff, architects designers and other city landscape designers and planners, and PHILPS lighting together to explore how to build the harmonious relationship between people and the city lights, between the three, proposed to create more attractive city environment. Application of energy saving lighting in urban construction.

However, in January 8th the seminar, Nanjing City streetlights Management Office Deputy Chief Engineer Liu Leishi said: 08 years of Nanjing began in August 6 manufacturers of different LED lamps are installed in the west side of the city of Taishan Vanke bright way to do the test results, not only the various light performance differences, but also with a lamp in different periods also different performance. These 6 lights power ranging from 120W-168W, some of the power 168W lamp brightness is not as good as 120W lights. Even more strange is that after a period of time, two brightness rise, 4 brightness decline, life span is also different.

In addition, Liu Lei pointed out: the current LED lamp products there is no uniform standard to production, there is no way for the road maintenance; to do the test lamp manufacturers to provide the product upgrading and very fast, there is actually a few months out of the original product test; and the normal use of HPS lamp is at least periodic 5-8, so the existing street lamp personnel can quickly to determine and maintain the high-pressure sodium street lamp.

Since the performance of the LED lamp is not stable, then how to achieve energy saving Nanjing street lighting system, in this regard, Liu Leishi said that the traditional street lamps can be used to reduce voltage and power down and other ways to achieve energy saving. Nanjing this year all new street lamps will be used to change the power of the ballast, turn on the lights 6 hours after the automatic power down: from 400W to 250W, down from 250W to 150W, down from 150W to 100W. Longpan road has adopted automatic voltage drop of the street, the "new projects this year will be reduced using all this power facilities, and about more than 2 thousand and 600 will transform the old lamp lamp.
