Urban road lighting is an important part of the city's night scene. It also has many urban functions such as ensuring the safety of vehicles and pedestrians at night, creating a comfortable visual environment, improving traffic efficiency, and reducing crime. Therefore, this is a necessary livelihood project, so the following principles should be followed in the implementation of road lighting projects.

1. Urban road lighting engineering standards are as follows:

a. The specifications and spacing of street lamp foundations, equipment foundations, embedded parts, reserved holes, and anchor bolts should meet the architectural design requirements.

b. The verticality of the two poles is ≤3mm/m.

c. The installation position of the street light pole: the deviation of the pole from the center line shall not exceed 50mm;

d. The grounding resistance of the metal lamp post of the street lamp is 10Ω.

e. The grounding resistance of the street light control box and the distribution box ≤ 4Ω.

d. The insulation resistance of the street light control box, distribution box, and feeder (relative to the ground) is 0.5 meters or more.

f. The power supply sequence of street lights should meet the design requirements;

g. The street lamp should light up normally after starting.

h. The lighting control and time control functions of street lamps should be consistent with the lighting design requirements.

2. The municipal road lighting source should be selected according to the following requirements:

Highways, main roads, secondary roads, branch roads, etc. all use LED light sources or high-pressure sodium lamps.

In residential areas, roads where motor vehicles and pedestrians travel together should use lead light sources, high-pressure sodium lamps or low-power metal halide lamps.

You can use LED light sources or metal halide lamps, such as urban centers, commercial centers, and other motor vehicle traffic lanes that require high color recognition

Pedestrian streets in commercial areas, pedestrian walkways in residential areas and sidewalks on both sides of motor vehicle traffic roads can use LED light sources, low-power metal halide lamps, thin pipe diameters or small fluorescent lights

3. The selection of urban road lighting lamps and their accessories should meet the following requirements:

When using high-pole luminaires, floodlights or floodlights with appropriate power and light distribution should be selected according to the characteristics of the place.

When using enclosed road lighting fixtures, the protection level of the light source cavity shall not be lower than ip54. For roads and places with serious environmental pollution and difficult to maintain, the protection level of the bulb cavity should not be lower than ip65. Optical cavity protection level cannot

Lamps with good corrosion resistance are used in places or places with high levels of corrosive gases such as acid and alkali in the atmosphere.

4. Large bridges are prone to strong vibration when passing motor vehicles. The lamps used should meet the current standard GB7000.1 "General safety requirements and tests for lamps"

High-intensity gas discharge lamps should be equipped with energy-saving inductive ballasts, and low-power lamps can be equipped with electronic ballasts.

The installation distance of the trigger, ballast and lamps of the high-intensity gas discharge lamp should meet the product requirements.
