Night, when the lights turn on, the contour 14 km walls are uniformly illuminated. The 1,200 units of floodlights and 1,000 sets of walls together constitute the main body of the Ming city wall lighting engineering. Nanjing Street Lights Office Technology department states, 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 and also to ensure maximum green energy become a basic engineering design requirement.

Thus, green energy-efficient LED lights have 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 afterward, 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 the lights in the Ming City Wall project are 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 has different lighting schemes, major holidays lighting time 4-5 hours, weekdays lighting time control in three hours, to avoid waste of resources. led grow lights https://www.eneltec-led.com/products/led-grow-lights

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. best led headlights http://bestledheadlight.com/
