Lighting by scientific and reasonable in order to ensure the normal operation of urban functions and the beauty of the urban environment, while avoiding the negative effects of lighting, working and living environment of residents, recently, Beijing issued the first "outdoor lighting interference optical limiting norms" local standards, will come into operation on 1 December.
Standard restrictions index, are internationally accepted indicators. Limit object for a variety of outdoor lighting fixtures, including street lighting, landscape lighting, advertising lighting, etc. limit the interference of light. Evaluation by functional properties of the standard by ambient light. Lighting design requirements should be affected by the lighting of the potential victims of interference of light objects analysis and evaluation, considering the requirements of lighting effects and lighting intensity distribution.
Set all kinds of lighting, surrounding residential buildings, should be accounted for and control the brightness of the lamp toward the bedroom window and windows on the facade of the illumination; non-road vehicles on both sides of the road lighting should be glare evaluation.
Non-commercial and non-cultural entertainment district should not be set lighting patterns change frequently, and should be limited to commercial and entertainment district, sports stadiums and other places the lighting for such areas of the environment outside the region of interference of light.
Rare trees should not be set landscape lighting, lighting for ordinary trees should be controlled illumination time and light intensity.
Lighting should not be installed in the trunk, in the trees around the installation of lighting should not affect the root growth of trees.
Installed decorative light bulbs on the tree, the selection of a single light source power should be less than 1W, the surface temperature of the bulb should be recognized below the damage to trees and disturbance of their growth temperature.
Not relevant in animal habitat area and landscape lighting set up protected areas, in animals or insects may be the locale of the places where lighting should be restricting the use of animals and insects that affect light.
Meanwhile, the development lights-out time, control lights lit the lamps during the period type, number and light intensity.

"Interference of light", meaning the amount of light, direction or spectral characteristics, in particular occasion this led to discomfort, reduced ability to distract or visual light. Too much or excessive interference of light will light radiation on human health and adversely affect the human environment, resulting in the formation of light pollution.
Will suffer interference due to light of different objects into four categories:
Residential area of interference of light interference: light launched into the bedroom residential buildings, affecting the lives and the rest.
Interference with road traffic light interference: The road around the various off-road due to improper lighting brightness, light direction, or mounting position, causing glare on the impact of motor vehicle drivers, resulting in decreased visual visibility.
Interference with pedestrian interference of light: the sidewalk because of improper lighting brightness, light direction, or mounting position, causing glare on pedestrian impact, resulting in decreased visibility of their vision.
The interference of light pollution the night sky: lighting direct or reflected light to the night sky, affecting astronomical observations.
