Nanchang built using LED street light two-way ten Lane main road

Chinese Jiangxi city of Nanchang province has been selected as one of the national "ten city lights" pilot city. However, the lighting facilities of Bayi Avenue Nanchang district has been running for more than ten years of aging is more serious, and the city's main longitudinal axis of the city environment is very asymmetric, street lamp flux has dropped to below 50% at the early stage of construction. Moreover, the past one or two years, frequent line failure, the need to upgrade the overall facilities.

The Bayi Avenue Road Lighting with LED street lamp energy saving and environmental protection, beautiful, local independent research and development for LED street lights and lighting crystal with high luminous efficiency, by the national testing center of electric light source light effect is 108.6LM/W, is the highest in the world of street light effect so far reported.

After calculation, in Bayi Avenue along with an average interval of 35 meters in the double light source arranged symmetrically on both sides of the road 12.8 meters high double cantilever steel lamp, single pole power 420W, a single rod power before 1300W down nearly two times. The replacement of lamps than before the high-pressure sodium lamp not only energy saving more than 60%, and the technical index of road lighting than before has greatly improved, the average illumination of 35LX, illumination uniformity 0.873LX, longitudinal uniformity is very good. In order to strengthen the Yangming Road lighting effect, overlapping Road, road, Zhongshan Road, Minde Road, Station Road West Wing uncle seven junctions, LED street lamp set 15 metre high light bar. The currently installed two light and two cantilever steel street about 150 bar, LED street light source in the bar about 20 bar, a total length of 3.9 km of Bayi Avenue, the total installed 359 lanterns and crystal lighting high-power LED lamp, so that each traffic intersection very bright.

At the same time, the number of lamps with single lamp dimming control of lamps, through PLC programming, the single lamp at midnight traffic under the condition of less, automatically reduce the power of the whole lamp 50%, the energy saving is more obvious. Because of the continuous regulation and control of electronic equipment, lamps, power supply and electronic equipment can be operated continuously and stably under rated voltage and rated current.

This is the world's first pioneered the use of LED lamps in the main road traffic on the two-way ten Lane Road, city road lighting to achieve the photometry (Design) standard ME1 level; this means that the technology and application of LED road lighting in Jiangxi province has reached the international advanced level.
