Shanghai takes aim at blinding LED boards

SHANGHAI is going to reduce light pollution caused by light-emitting diode (LED) boards, which are too shiny and disturbing to drivers.

Officials from Shanghai Greenery and Public Sanitation Bureau said they drafted an amendment to the city's regulation on urban lighting and it will be approved soon.
The current regulation issued in 2004 does not cover the use of LED, which was not widely applied at that time, officials said.

Li Shuzhi, an expert from the Shanghai Research Center of Engineering and Technology for Solid-State Lighting, said they began LED research in 2008 when more and more LED advertising boards appeared in the city, especially in business centers and tourist spots.

He said Shanghai has at least 1,000 LED boards. "There are more than 100 such boards along Huaihai Road," he added.

"LED technology has been mature enough to generate super brightness. Advertisers prefer brighter boards that can be seen far away. But the LED technology should be used properly." Li said.

"Users must consider the angle and brightness of their LED boards to prevent glare, distraction and eye fatigue. Glare is dangerous to drivers and can cause traffic accidents."

A driver said he always felt momentarily blind while passing a bright LED board on Xujiahui Road.

Doctors said a prolonged look at a bright LED board can impair one's vision.
