Urban road lighting solutions

Road lighting

Setting up illuminators on the road provides the necessary visibility to vehicles and pedestrians at night.
Road lighting can improve traffic conditions, reduce driver fatigue, and help improve road capacity and ensure traffic safety. In addition, it can beautify the city.
Road lighting is generally divided into urban road lighting and tunnel road lighting.

Quality of road lighting

Brightness level

The average brightness of the road has different brightness requirements according to the road grade. Generally, fast roads and main road asphalt roads require brightness requirements of 2 cd/m2 or more. Secondary trunk roads and auxiliary roads or residential roads are relatively low. For details, please refer to "City Road Lighting Design Standard CJJ45-2006" and "Highway Tunnel Ventilation Lighting Design Specification JTJ026.1-1999"

Average illumination

The average illuminance refers to the average value of all illuminances on the road surface and is the unit of illumination intensity, which is generally expressed by Lx.


Road lighting should strive to limit the range of uncomfortable glare to a certain extent. Generally expressed by the G value. Under normal circumstances, G ≥ 7 (G = 1 will be unbearable, commonly known as light pollution).

Visual induction

Let the driver immediately recognize the direction of the road at a certain distance, especially the direction of the road he wants to take.
