“Why is the blue light shining at night under the elevated?†The careful citizens may find that in the last two weeks, the Yan’an Road elevated and the north-south elevated in the central area of ​​Shanghai will light blue and purple every night and overhang the two sides of the viaduct. The lower part of the exit deck is illuminated.
The Morning Post reporter learned yesterday that “Elevated Blu-ray†is part of the Shanghai Elevated Festival Landscape Light Reconstruction Project and is currently in the trial light stage. In addition to the current cool-blue "Blu-ray" project, the extension will have a warm-toned lighting strip. After the test light period is over, the warm and cold landscape lights will mainly light up during the weekends and festivals, and will not open every day.
Landscape light renovation project
According to the relevant person in charge of the Municipal Management Office, the reconstruction of the elevated landscape lights, Yan'an Road elevated from the west to Urumqi Road, east to Huangpi Road, north and south elevated north from Fengyang Road, south to Nanchang Road, including Yan'an Road North and South elevated Interchange, set the total length of the landscape tube is about 17 kilometers.
It is understood that the original Yan'an Road elevated and north-south elevated also use blue-violet lights as landscape lighting, but the use of fluorescent tubes, when lighting, two thin bands of light are formed on both sides of the elevated. However, the life of fluorescent tubes is relatively short, and the shock resistance is poor. Many of them have been damaged for more than 10 years, and it is time to update.
It is reported that the high-rise landscape lights have undergone design, evaluation and demonstration for about one year in the early stage of reconstruction. They have also tested various colors and finally decided to adopt the current blue-violet color, which is also a continuation of the original landscape lights.
Will also build a warm tone lighting belt
The reconstruction began in October last year and lasted for 3 months. Due to the road traffic during the day, it was impossible to climb the work. The whole construction was arranged every night to the middle of the night. The current landscape light tubes are distributed on the edges of the lower sides of the lower deck of the viaduct. After lighting, two light corridors of 4 meters wide are formed under the viaduct panel.
"Now, there are 27 1 watt LED lights in each of the lamps about 1 meter long, so that the brightness of each tube is relatively high to illuminate the lower part of the entire bridge deck. Compared with more power saving, the service life is longer. At the same time, this time, constant current control is also adopted, and the voltage fluctuations will not make these landscape lights flicker."
It is reported that the existing landscape lighting belt will also extend, Yan'an elevated to Henan Road, north-south elevated to Ganxi Road, along the South Zhongshan Road from Nanpu Bridge to Tunxi Road will also build a warm-colored landscape lighting belt, thus forming The layout of the elevated landscape lighting in the city center "two horizontal and one vertical".
The blue-violet landscape lighting is unique. According to experts, as a cool color, it is more suitable for summer, and winter may make people feel cold visually. It is reported that the relevant departments have decided that in addition to the current test light stage, the future will only be opened on weekends, holidays or during important events, generally ending at 10 pm, of course, the number of days of lighting during the Expo this year will be more.
