Chengdu, a city with a long history of city lights. “Late Registration Dacisi Court on July 6 View Night Market”, Tang Tian situation that is “consistent Huang Wanli silver violet virtual” praise. Lu Song, “later than 5” is also a “late night call sommelier east, five lights of downtown advocate,” the poem. Guangxu twenty eight (1902), Chengdu, the first street there?? Dish lamp. 1924, Chengdu formal power street lights appeared, but few lights, city by dark. Now, when night came, the whole of Chengdu brightly blooming, bright stars, the ocean of light.

“Turning lights, I remember There is a saying called Chengdu ago: ‘uneven road, street lights unknown’.” Zou 77-year-old uncle called “old lights” is the earlier street administrator. “In the past, we have 10 people on the city to control more than 1,000 lamps, fully rely on manual control switch.” In 1950 he was a guy early 20s, every day starting from the house well street, street lamps to east Area push light.

In fact, Chengdu, in 1924 formally appeared on the street. There was no professional management, street lighting and slow development. To 1949, only 1500 street in Chengdu, about 800 to light. With the growth of new China, street lighting has also been rapid development, to the end of 1952 the street in Chengdu increased 4 times, about 3227. The early 60s, set up a street light by the Chengdu, the first street just 10 employees, is divided into four groups, are responsible for maintenance during the day and night patrols. Who is on night duty, the task lights switch to him. “Manual control switch lamp, not a lamp to pull on, as long as the total gate Tuishang Qu on the line.” Zou said the old, street lighting is the series control, if the city’s street lamps are strung together, very close behind even dim light. Therefore, we must turn away from the roadside at regular intervals transformer, ensure each street lamp has enough power. In order to light up different sections of the street at the same time, we should set up one by one control box. The total gate a Tuishang Qu, “despair” to look at the first AC contactor control box closed, the first paragraph of bright lights, while the power spread to the second control box, the second paragraph is also bright, and the third paragraph.

Early 70s, Chengdu brought out the clock control switch, can switch the time to develop automatic opening and closing procedures. “However, the clock control also has shortcomings, is unstable.” Chengdu street management Sunzhu Ren said. For example, many summer thunderstorm season, the weather can not dim when the lights turn on in time. After all, when the control switch machine, can only set the time to check, very “rigid”, “Sometimes there will be lights that light does not shine, not out of the quenching phenomenon.”

Sun Zhuren introduction, when the Chengdu area of several hundred bell tone again, almost half, emphasized the transfer and did not have 10 minutes off the time difference, it is sometimes different sections of the open and extinguished lights are not synchronized. Shift workers but also under the shade of the morning and evening weather seasons, 10 days half the time on the clock debugging.

To 1983, Chengdu street lamp type, source, control and management, have been greatly improved, and entered the country 21 “10 000 street lamps,” the city ranks.

Chengdu, a total of more than 500 surveillance terminal placed in the path of urban power distribution box each and every terminal control of street lamps within 500 meters radius. Three remote system remote monitoring and control of all terminals, in a timely manner to reflect the failure of various sections of street alarm.

From early 2000 to the present, Chengdu, grasp the historical opportunity of Western Development, the development of street lamps, there has been significant progress, centralized maintenance and management to expand the scope of the First Ring Road, to within the outer ring; from within the Second Ring Road The Street and Lane street reconstruction to within three-loop non-lamp street lamp road construction … … At present, the facility total to: lamp 67497, 20799 Landscape lighting Mileage 1221KM. Today’s Chengdu, has become a major international Urban Lighting lighting system will be.
