When you drove on the main road in Changchun, you would suddenly feel a white light. When you opened your eyes, you discovered that this was not the high beam of the opposite car, but the LED billboard hanging on the building. Recently, Changchun citizen Ms. Wang encountered this phenomenon at night when she drove through the intersection of Liberal Road and People’s Avenue in Changchun.
Citizens took a look at the crossroads and other red lights and brushed them in front of them. Ms. Wang, a Changchun citizen, frequently worked night shifts. Recently, Ms. Wang drove home from work and traveled from south to north via the Liberal Road of Changchun City and People's Avenue, and was crossing the road at a red light. Suddenly, Ms. Wang felt a bright start, and suddenly she couldn't see anything, and her eyes were white. Subsequently, Ms. Wang carefully observed that the original dangling to her eyes was a LED billboard hanging in front of a unit building in Changchun City. The advertising background is relatively white, it is very bright at night, especially against the surrounding night scene.
Ms. Wang said: "Fortunately, at the time, waiting for the red light, if the eyes were shaken while driving, it would be more dangerous."
The reporter visited several intersections in Changchun with LED billboards. At around 10:00 on February 15, the reporter visited some sections of the People’s Avenue in Changchun City. It was found that there were two LED billboards at the intersection of Renmin Avenue and Liberty Road, and there was an LED billboard at the intersection of Renmin Street and Nanhu Parkway. The lengths and widths of two LED billboards at the intersection of Renmin Avenue and Liberty Road are both about 10 meters. Advertising images are being played on LED billboards, and there is no sound. From the screen point of view, the background of the advertisement may suddenly turn white, but viewing during the day is not very dazzling. Subsequently, the reporter asked three drivers who were waiting for a red light, and two drivers indicated that they were dazzling at night. Around 19:00, the reporter once again came to the intersection of Liberal Road and People's Avenue in Changchun City. At this time, the advertising screen on the LED billboards constantly changes and the advertisement of the car is being played. Sometimes the background of the advertisement will be relatively white, and it is indeed more dazzling in the night sky.
"It was a bit dazzling at night, but it would be better if you didn't look at it," said the driver Zhang.
The advertising company will lower the brightness of night LED billboards by about 10:00. The reporter went to the Changchun Electric Power Bureau. A staff member stated that the billboards on the floor are responsible for the advertising company. Which of them is not very specific? clear.
After investigation, the reporter learned that the billboard on the building of the Changchun Electric Power Bureau was responsible for the advertising agency of Changdu City.
Around 14:00, the reporter contacted Ms. Tong, a staff member of the advertising agency in Changchun City. Ms. Yan said that recently they did not receive any complaint from the public that LED billboards were too bright at night. The content on the LED billboard is provided by the advertiser and will be replaced some time later. Recently, they will appropriately lower the brightness of this LED billboard at night.

Staff Zhang Weiguang said, according to relevant regulations, LED billboards should have different day and night brightness, advertising companies should adjust the brightness of LED billboards sooner or later, during the day can be bright, at night should be a little darker.
