The relationship between LED street lamp power, lamp pole and height and road width

The height of general lighting is 8 meters, the distance between street lights is generally 30 meters, and the light source can be led150w or high pressure sodium lamp 250w.
First:
Common LED street lamp replaces traditional high pressure sodium lamp w number comparison table:

LED street light w number high pressure sodium lamp pole height
40w 100w 5~6m
90w 150w 6~8m
120w 250 8~10m
180w 400 11~13m
Second:

Comparison table of commonly used w numbers and pole heights of LED street lights:
6w (yard light) pole height 3m
8w (yard light) pole height 3.2m
10w (yard light) pole height 3.5m
12w (yard light) pole height 4m
15,18,21,24w (LED street light) The height of the pole is 5m, and the width of the road is 6~8m
30w,36,42w lamp pole height 6m, road width 8~10m (2 lanes)
60w (LED street light) The height of the pole is 7~8m, and the width of the road is 10~15m (3 lanes)
80w (LED street light), the height of the light pole is 8m, and the width of the street light is about 16m (two-way 4 lanes)
Note: This table is for reference only; the specific application needs to be determined according to the lighting time and the number of rainy days;
three. Road lighting standards
According to the "Urban Road Lighting Design Standards": the average illuminance of express roads is 20lx, the uniformity is 0.4, the average illuminance of main roads is 15lx, the uniformity is 0.35, the average illuminance of secondary roads is 8lx, the uniformity is 0.35, the average illuminance of branch roads is 5lx, the uniformity 0.3.
Note: This is the illuminance standard for high-pressure sodium lamps, and there is no uniform standard for LED street lamps in China. Specific reference to the development of standards in various regions.
