The standard stipulates that all live parts of the lighting equipment should be protected by insulation, obstruction or external protection; the lamps that are accessible to the human body on the protective fence (wall) such as the viewing platform, bridges, etc. should use Class III lamps, that is, the protection against electric shock is dependent on the power supply voltage. Very low voltage.
Night lighting should not interfere with the normal use of traffic signals and communication equipment. Dynamic lighting should not be used on overpasses and crossing bridges. There should be no large-scale, continuous use of decorative lights with fast color changes and multiple light sources on both sides of urban motor vehicles. Luminaires installed on ancient buildings should have fire protection signs. The neon lights installed in the open air should be protected from rain. The neon lamps should be fixed by special insulating brackets and they should be firm and reliable. The distance from the surface of the building should be no less than 20 mm.
For lighting equipment accessible to personnel, if the surface temperature is higher than 60 °C, isolation protection measures shall be taken; floor-standing lamps installed in dense places such as sidewalks shall be fence-free and the installation height shall be 2.5 meters or more above the ground.
The standard also stipulates that the luminaires should be reliably fixed. The luminaires used in the vibrating place should have anti-shock measures. The luminaires installed at high altitude should have anti-wind pressure measures. The brackets and parts required for the installation of the luminaires should be treated with anti-corrosion treatment. In addition, underwater luminaires should be equipped with rubber insulated cables of corresponding length and specifications according to the site conditions.
The standard is a mandatory local standard. After the announcement, all the buildings, plazas, bridges, gardens, places of interest, roads, parking lots, blocks, green spaces, sculptures, outdoor activities, etc. of the city must be built according to standards or Trimming.
According to the reporter, the city will also develop local standards to limit light pollution. The "Outdoor Lighting Light Interference Limitation Specification", which is also seeking comments, stipulates that it is strictly forbidden to use light sources that are harmful to trees to illuminate trees. It is strictly necessary to limit the use of light sources containing harmful spectrum to trees in landscape lighting around trees. Set the night illumination. Night lighting should not be set for rare trees; lighting for ordinary trees should control lighting time and light intensity; lighting facilities should not be installed on trees, nor should they affect the root growth of plants. After the publication of the standard, the common practice of winding neon lights on trees in the city will be banned.
In addition, the city will also ban night lighting in animal habitats and related protected areas. When lighting is set in areas where animals or insects may be active, the use of light sources that have an impact on animals and insects will be restricted.
