Using energy-saving LED street lighting and beautiful

　　Night, the lights turn on, the contour 14 km walls are uniformly illuminated, 1,200 floodlights, 1,000 sets of Wall together constitute the main body of the Ming city wall lighting engineering. Nanjing Street Lights Office Technology department heads, as early as the Ming City Wall in the city landscape lighting project started at the beginning, how to both highlight the city wall of historical and cultural heritage, but also to ensure maximum green energy, become the basic engineering design requirements .

　　To this end, the green energy-efficient LED lights has become the first choice. According to reports, the traditional lighting of the lamp power is generally in 250W, using LED lamps, can achieve the same brightness as long as 70W, 120W LED light can reach 400W traditional lamp lighting effects. The responsible person said afterwards, with 70W and 250W of LED lights compared to traditional lamps, the same lighting time, LED lamp energy saving 72%. But because the lighting project also uses a portion of 120W of LED lights, saving an average of more than Liu Cheng.

　　Careful people also found time to Ming City Wall lights lighting project is not the same every day. In general, the Ming city wall lighting lamps fixed from 19:00 lights, turn off the lights and sometimes zero, sometimes ahead to 11:00, 10:00 or even turn off the lights. In this regard, I learned that the remote automatic control system developed for weekdays and holidays different lighting schemes, major holidays lighting time 4-5 hours, weekdays lighting time control in three hours, to avoid waste of resources.

　　In charge of the city wall lighting engineering design personnel, the Ming city wall lighting project has also designed a manual system, when faced with heavy rain and other inclement weather, fewer tourists, managers can also advance the closure of some lights by manual control, or advance lights.

　　Many places on the walls are bright green trees, the night, between the actual situation and white walls and plants, light and shadow dancing. City Street Lights Office in a designer view, the Nanjing city wall lighting project emphasizes silhouette of green plants, full of natural flavor under the lights. In order to highlight the effect of green silhouette, designers consider in advance the location of the lights, spacing and brightness, adjust to local conditions in many parts of the lamp position to achieve the effect of sunlight and shade beautiful. This will not only avoid the use of high-polluting, high-power lights, but also highlights the energy-saving ideas.
