How to choose the right height and power of solar street lights? -Experience of Lighting Designer

Introduction

As a lighting designer, I often come across this question: how to choose the right street light height and power according to the width of the street? This question seems to be simple, but actually involves many factors that need to be considered comprehensively.

The relationship between road width and solar street light height and power

The width of the road is one of the most important factors affecting the choice of solar street light height and power.

Generally speaking

Narrow road (5-8 meters):

For this narrower road width, the height of the lamp post can be relatively low, generally between 5-7 meters. For power selection, due to the small irradiation range, relatively low power street lamps can be selected, such as 30-60 watts.

Medium width streets (8-12 meters):

The height of the pole for this width can be increased appropriately, generally between 8-10 meters. The wattage can be 60-100 watts.

Wide road (more than 12 meters):

For wide roads, the height of the lamp post should be further increased, generally more than 10 meters. The wattage can be 100 watts or more.

Factors that influence the choice of height and power of the lamp post

However, this is not an absolute rule. There are many other factors that influence the choice of height and power of the lamp post, such as

Traffic flow:

Road traffic flow, the need for a higher degree of illumination, so you can increase the height and power of the appropriate light pole.

Environment:

The surrounding buildings, trees, etc. will cause shadows on the light, so you need to consider supplemental light sources.

Weather conditions:

Fog, rain and other inclement weather, the need to increase the power of the lamps.

Energy consumption:

Lamps with high light efficiency and long life should be selected and combined with intelligent control system to achieve energy saving effect.

My personal experience and suggestions

In many years of lighting design practice, I found that choosing the right height and wattage of lamp poles is not only a technical problem, but also an art. I always adhere to the principle of “tailor-made for local conditions, customized to suit the needs”.

People-oriented: Lighting design is ultimately for people. We must consider the comfort of pedestrians, the visual experience of drivers, and the safety of nighttime activities.

Aesthetics: Lighting is not only functional, but also artistic. Reasonable arrangement of lamps and street lights can improve the quality of urban landscape.

Energy-saving and environmental protection: Lighting design should be combined with the concept of energy-saving and environmental protection, and energy-saving lamps and street lights should be used to reduce energy consumption.

Recommend Pole Height and Lamp Power for different width of Road

For roads of 5-16 meters, I suggest

Road Width	Pole Arrangement	Pole Height	Lamp Power
Narrow road (5-8 meters)	Single side light	5-7 meters	30-60W
Medium width streets (8-12 meters)	Double side lights	8-10 meters	60-100W
Wide road (more than 12 meters)	Double side lights, or the Middle of the Road	10-12 meters	100-120W

Of course, this is only a general range, the specific program should be adjusted according to the site conditions.

Summarize

Choosing the right pole height and power is a systematic project that requires comprehensive consideration of many factors. As a lighting designer, I am glad to share my experience with you and hope it can help you realize better lighting design.
