The 2200 sets of LED lamps illuminate the Ming city walls of Nanjing and can be remotely controlled

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 light was lit, and the outline of the wall of the 14 kilometer wall was uniformly lit. The 1200 sets of floodlights and 1000 sets of wall lamps 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, the green energy-saving LED lamps become the first choice. According to reports, the traditional lighting power is generally 250W, the use of LED lamps, to achieve the same brightness, as long as the 70W can be, 120W LED lights can reach the 400W lighting effect of traditional lamps. The person in charge said, "to 70W LED lights and 250W traditional lamps compared to the same lighting time, LED lights energy-saving 72%.". However, because the lighting project also uses part of the 120W LED lights, the average energy savings of more than 60%.

Careful people also found that the Ming city wall lighting project lights out every day is not the same. Generally speaking, the Ming city wall lighting lamp fixed from 7 in the evening lights, and sometimes zero lights, and sometimes advance to 11 points, or even 10 lights. 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 lights management office, a designer seems, Nanjing city wall lighting project emphasizes green plants silhouette effect, full of natural charm. In order to highlight the silhouette effect of green plants, designers have considered the position, distance and brightness of the lamp in advance, and adjusted the position of the lamp according to local conditions, so as to achieve the beautiful effect of light and shade interlaced. In this way, not only the use of high pollution, high-power lighting, but also highlights the concept of energy conservation.
