The city's local standard "Specifications for Limitation of Outdoor Lighting Light Interference" has been officially released since it was collected in July last year and will be implemented on December 1.
Optical interference regulations
When I was sleeping at night, I was swayed by the advertising light box on the opposite floor, and I was lighted up in the room. I was driving on the road and was flashed by a huge flashing screen. The relevant person in charge of the Quality Supervision Bureau said that these all belong to the category of light pollution.
The standard requires that when setting up various types of lighting around the house, the brightness of the lamps facing the living room windows and the illumination on the facade of the windows should be accounted for and controlled. The standard also requires that when non-road lighting devices are installed on both sides of urban motor vehicles, glare evaluation should be carried out; it is not appropriate to set up frequently changing mode lighting in non-commercial and non-cultural entertainment areas of the city. According to different classifications, the standard specifies the specific limits of the light interference of the lighting device, including the light intensity limit of the luminaire facing the window of the residential building; the limit of the surface brightness of the advertising sign; the light intensity of the lighting fixtures arranged on both sides of the sidewalk And brightness, etc.
