Night, the lights came on, the contour 14 km walls are uniformly illuminated, 1,200 sets of floodlights, 1,000 sets of wall lamps together constitute the main body of the 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, green energy-efficient LED lamps become the first choice. According to reports, the traditional lighting of the lamp power is generally in 250W, using LED lamps, you can achieve the same brightness as long as 70W, 120W LED light can reach 400W traditional lamp lighting effects. The person in charge said afterward to 70W and 250W of LED lights compared to traditional lamps, lighting the same time, LED lights saving 72%. But because the lighting project also uses a portion of 120W LED lights, saving an average of more than Liu Cheng.

Generally, the city wall lighting lamp is fixed from 19:00 lights, turn off the lights and sometimes 0:00, sometimes ahead to 11:00, 10:00 or even turn off the lights. In this regard, I learned that the remote automatic control system was developed for weekdays and holidays in 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 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/
