Light pollution spread where is an end
On the whole, the advertising of big cities. The harm of city traffic, light pollution is more obvious than the countryside, and in the growing and spreading. This time, you need functions of regulation.
Taking shenzhen as an example, on outdoor advertising lighting management department has two main: urban management and market supervision. The urban management department is mainly responsible for setting, market regulators mainly responsible for the relevant formalities and level. At present, shenzhen outdoor lighting for approval and advertising billboards are mostly refer to wall body of the brightness of the light there is no clear rules. From market supervision, urban management, and then to the environmental protection department, has not been a real responsible departments, there are rules and regulations without enforcement departments, then, “method” will be useless?
Engaged in color r&d engineers, the shenzhen city people’s congress Zhou Mingming pointed out that outdoor advertising lighting “light pollution” hard to solve the crux of the problem is that there is no corresponding laws and regulations, “our laws and regulations on the management of LED display is not sound enough, on this piece of the standard, etc) hasn’t launch.” Zhou Mingming also said that the current installed in shenzhen most of the screen does not light sensor system, which, at present a lot of LED display in the city are set before outdoor advertising regulations related, thus caused the LED of the status quo. In fact, in addition to the LED billboard of dazzle light problem, light pollution of the city there are many ways. Zhou Ming said: “is not only LED lights, including some golden building, glass curtain wall, especially under the sun, there will be such a problem. The driver in the process of moving, will suddenly feel eye the pyramidal cells were bleached, blindness, which can cause the attention of the driver is short.”
