What do you think of light pollution? Netizens quarreled because of it. Some people think it has no actual impact, and others think it should be managed. According to extreme news It is reported that the LED horse running screen at the door of many shops in Funing County, Yancheng City, Jiangsu Province has been removed. In this regard, Funing County Urban Management responded that in order to avoid the light pollution caused by billboards, the dazzling led horse running screens in the whole county will be removed.
According to the report, the staff of Ningxian Urban Management Bureau and urban management and law enforcement brigade said that the move is to avoid the light pollution caused by advertising light boards at night. The local government will rectify the light boards of shops in the whole county, and the more dazzling light boards will be banned and replaced with non dazzling ones**
For the so-called light pollution, experts from Guangzhou Academy of Environmental Sciences said that the term light pollution mainly refers to the general term of interfering light or excessive light radiation (including visible light, ultraviolet and infrared light radiation) that has a negative impact on people's physical and mental health and human living environment, but it is not a strict environmental protection term. If the interfering light or light radiation produced by a light source has a negative impact on people's physical and mental health and human living environment, We can think of it as light pollution. If the light project (including urban road lighting, urban night scene lighting and other projects) has a negative impact on residents, pedestrians, motor vehicle drivers or human living environment, it will also cause light pollution.
Internationally, light pollution is generally divided into three categories: white light pollution, artificial day pollution and color light pollution. At present, there is no reference to "light pollution" in China's law, and there is no explanation and definition of light pollution. The previous management measures on light issued by Guangzhou used a scientific term "light radiation".
The energy propagated in the form of electromagnetic wave or particle (photon), which can be reflected, imaged or dispersed by optical elements. This energy and its propagation process are called optical radiation. Excessive light radiation will cause light pollution and affect human health
