2200 sets of LED lamps illuminate Nanjing Ming city wall can be remote control

Yesterday (15 days), the author from the Nanjing city street management office was informed that the city wall lighting project across the board with LED energy-saving lamps, energy saving than traditional lighting more than 60%, to achieve the "energy-saving jingmei".

At night, the lights light up, 14 kilometers of the city wall contour is evenly lit, the 1200 sets of floodlights, 1000 sets of wall lamp together constitute the main body of the Ming city wall lighting project. Department of technology of Nanjing city street management person in charge, the city started early in the Ming Dynasty city wall landscape lighting project at the beginning, they not only show how walls of historical and cultural heritage, and to ensure the maximum degree of green energy, has become the most basic requirements of the design of the whole project.

To this end, green energy-saving LED lamps become the preferred. According to reports, the general power of the traditional lighting in the 250W, the use of LED lamps, to achieve the same brightness as long as 70W, 120W LED lamp can reach the lighting effect of the traditional 400W lamps. The person in charge said, to 70W of LED lights and 250W compared to the traditional lamps, the same lighting time, LED lamp energy saving 72%. However, because the lighting project also uses some of the 120W LED lights, the average energy saving of more than 60%.

Careful people also found that the Ming city wall lighting project is not the same time every day. In general, the Ming city wall lights fixed from 7 in the evening to turn on the lights, and sometimes turn off the lights, sometimes up to 11 points, or even turn off the lights at 10. In this regard, I understand that the automatic remote control system for the weekday and holiday for different lighting schemes, major holidays working time 4 to 5 hours on weekdays, the lighting time is controlled in 3 hours, to avoid the waste of resources.

Responsible for city wall lighting engineering design personnel, a manual system design of city wall lighting project, when encountered heavy rain and other inclement weather, fewer tourists, managers can also close some lights in advance through manual control, or turn off the lights in advance.

Many places in the Ming city wall is green shade, curtain walls and plant, between real and virtual light dancing. In the city street lamp management department, a designer seems, Nanjing city wall lighting project highlights the effect of the green plant silhouette, natural flavor full. In order to highlight the effect of green plants silhouette, the designer took into account the position of the lamp, spacing and brightness, adjust the position of the lamp in a number of local conditions to achieve the beautiful effect of light and shade staggered. This avoids the use of high pollution, high power lighting, but also highlights the concept of energy saving.
