Setting standards for street lights on the main road of the hospital in 2025
1. Standard lighting height
Street lamp pole height :
If large vehicles pass through the main road of the street lamp courtyard or need high coverage lighting, it is recommended to use 6-8 meters lamp pole, taking into account the needs of lighting intensity and energy saving .
If the road width is narrow (such as less than 8 meters), you can choose 5-6 meters lamp pole, suitable for 20-40W lamps .
Lighting installation specification :
The installation height of the same road street lamp must be consistent, and ensure that the height from the center of the light source to the ground is uniform .
2. Requirements for illumination and light source
Street lamp illuminance standard :
The illumination of the road surface of the street lamp should reach 20-30 lx, which is close to the lighting standard of the urban main road to ensure the safety of traffic at night .
If the traffic flow in the courtyard is low, it can be appropriately reduced to 15-20 lx (refer to the standard of the sub-trunk road), but should be evaluated according to specific scenarios.
Light source selection :
It is recommended to use LED street lamp , suitable for 30-60W power, to meet the needs of energy saving and long life .
Street lamps should be truncated to avoid glare interfering with pedestrians or vehicle drivers .
3. Lighting arrangement and elevation design
Layout :
Use one side or two side symmetrical lighting , lamp pole spacing according to the illumination requirements set (usually 3-4 times the height of the lamp pole).
The vertical axis of the lamp shall be perpendicular to the road axis, and the street lamp shall ensure that the light is concentrated on the road .
elevation adjustment :
The elevation Angle is set according to the road width and light distribution curve. The center line of the light source should cover the 1/3-1/2 area of the road width .
After the lamp holder is installed, it is necessary to tilt the lamp holder towards the road at a certain Angle (for example, the lamp holder of a long arm lamp is tilted 100 mm sideways). Optimize the lighting cover .
4. Maintenance and quality requirements
facilities in good condition :
The completeness rate of street lamp facilities shall be ≥95%, timely repair of faulty lamps and lanterns, and avoid large area lights off .
lighting rate standard :
The lighting rate of the main road street should be ≥98% to ensure the continuity of night lighting .
