What Should Be the Pole Height and Distance Between Poles in Street Lighting?

The position of the light fixture is as important as the selection of light fixture in order to illuminate correctly to streets, roads, and sidewalks. You will not achieve the desired performance when you do not locate the light fixture correctly.

The height of the lighting pole to be used is related to the width of the area to be illuminated. 4-5-6 meters height of lighting poles are used in sidewalks and bicycle roads. 8-10 meters lighting poles are preferred in narrow streets and byroads. 10-12 meters height of lighting poles are used in boulevards, commercial and industrial areas.

There will be too bright and too dark spots when the height of the pole is not in proper measure.

If the distance between poles are high, you will use less pole and light fixture. This will reduce the cost. The distance between poles are related to the height of the pole to be used. If the height of the lighting pole is high, the distance between the poles will also be high. If we need to give a general ratio in this regard, it would be appropriate to leave 2,5-3 times the height of the pole between the two poles. For instance, in projects where 6 meters lighting pole is used, 15-18 meters distance can be left between the poles.

If the distance between poles are too high, there may be dark spots between two poles. If the distance between poles are too low, there may be bright areas between two poles.

The width of the area illuminated by the lighting fixture is roughly equal to the height of the lighting pole. In other words, a light fixture mounted on 12 meters height of a lighting pole can illuminate 12 meters width of road (lane width 3-3.5 meters) or area.

It is sufficient to illuminate one side of the road in narrow streets. In wider streets, it may be necessary to position the lighting poles on both sides of the road (opposite or shifted).

Factors such as speed limit, traffic density and crime rate that determine the class of road lighting should be considered in determining the height of the mast and the distance between the poles. The total light output and light distribution of the light fixture should also be considered in determining the height of the pole.

It should be verified by computer simulation software that the lighting pole and light fixture combination meets the standard requirements for road lighting.
