2200 sets of LED lights illuminate the Nanjing city wall 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 are on, 14 kilometers the contour is uniformly illuminated, 1200 floodlights, 1000 sets of wall together constitute the main body of the Ming Dynasty 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, LED has become the first choice of green energy-saving lamp. According to reports, the traditional lamp power is generally 250W, the use of LED lighting, as long as the 70W can achieve the same brightness, illumination LED lamp 120W can reach 400W traditional lamps. The responsible person said afterwards, compared to 70W LED lamps and 250W traditional lamps, the same lighting time, energy-saving lamp 72% LED. But because the LED lamp lighting project also uses part of 120W, the average energy saving more than 60%.

Careful people also found off day Ming city wall lighting project is not the same. In general, the Ming city wall lighting lamp fixed from 7 at night lights, sometimes zero off, sometimes in advance to 11 points, or 10 points off. 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 view of a designer streetlight management office, Nanjing city wall lighting project emphasizes the silhouette effect of green plants under the light, natural flavor. In order to highlight the green plant silhouette effect, designers to consider in advance the location, spacing and brightness of lights, lights in many places to adjust the position, to achieve a beautiful effect of sunlight and shade. This is to avoid the use of high pollution and high power lighting, and highlight the concept of energy saving.
