Street lights sometimes referred to as light poles, lampposts, street lamps, or road lamps, are elevated public fixtures that provide lighting along the side of a road or path when additional illumination is required. Automatic activation of light-sensitive photocells occurs at nightfall, sunrise, or the onset of dark weather. Street lights were initially employed in the 4th century in Antioch to keep people safe from stumbling on a walkway. The first broad system of street lighting relied heavily on coal gas as its primary fuel source. As beacon lights, highway lights, and bike path lights, innovative street lighting technologies such as LED and high-intensity discharge lamps are employed nowadays.

Street lighting comes in a variety of styles. street light lamps may be classified as LED street lamps, induction lamps, energy-efficient lighting, high-pressure sodium lamps, and metal halide lamps, among others. They are classified as standard street lights, high-post street lamps, courtyard street lamps, and landscape street lamps. Other types of street lights include single-arm street lights, dual-arm street lights, combination street lights, and solar street lights.
Prior to installing a street light, you must identify its function, such as illumination or landscaping. Following confirmation, you may elect to add street lights or garden lights. In general, street lights are more than 5 meters in length, whereas garden lights are around 3 meters in length. This directly affects the street light height.
The height of street light poles in general
How tall is the average light pole? the street lamp's (pole's) height is often 6 meters, 8 meters, 10 meters, 12 meters, or 15 meters. The street light height's particular use is determined by the breadth of the road surface. Generally, when just one sidelight is on, the street light's height equals the breadth of the road surface. Alternatively, the street light's height is less than one meter more than the width of the road.
The following chart illustrates the relationship between the power of common LED street lamps and the pole height: 30-60W street lamps have a pole height of fewer than 6 meters, 60-100W street lamps have a pole height of fewer than 8 meters, and 100-150W street lamps have a pole height of fewer than 10 meters.
Height of street lantern (street light pole height) The standard light pole height of traditional street lights is 4 meters, 4.5 meters, 5 meters, 5.5 meters, 6 meters, 6.5 meters, 7 meters, 7.5 meters, 8 meters, 8.5 meters, 9 meters, 9.5 meters, 10 meters, 10.5 meters, 11 meters, 11.5 meters, and 12 meters.
The garden light pole is often 3 meters, 3.5 meters, or 4 meters in height.
Generally, high pole lights are 15 meters or over in height.
Due to the fact that the height of the street light is dictated by the real scenario, the data above is for reference purposes only.
Factors affecting the height of street light poles
When determining the pole height, many factors must be considered: the site requirements; the traffic density; the road width; and the street light spacing.
A. Before installing street lights, the site must be determined, for example, rural roads, county-level roads, provincial-level roads, and so on. The installation heights vary. This is mostly determined by the road's width. For instance, a road that is 5 meters wide requires a pole that is 5 meters high, whereas a road that is 8 meters wide requires a pole that is 8 meters high.
B. The lamp's height must be determined by the vehicle density on the road and the kind of vehicle passing. For instance, if you have a huge automobile, you will require a high-end street light, although low-level street lights may be installed nearly without a large car. Install solar street lights at an appropriate height for the surrounding trees. The premise is that it must be adequately illuminated, and if the trees are little, the pole height may surpass the height of the trees.
C. The particular purpose of the street light height is determined by the width of the road. If the light is placed on one side, its height must be equal to the width of the road surface or less than 1 m in height. The following chart illustrates the relationship between the power of common LED street lamps and the pole height: 30-60W street lamps have a pole height of fewer than 6 meters, 60-100W street lamps have a pole height of fewer than 9 meters, and 100-150W street lamps have a pole height of fewer than 12 meters. If the city's major route has four lights parallel to each other, the distance is about 30 meters. The city's minor roadways are separated by two traffic signals around 35-40 meters apart.
D. The street lamp height's particular usage is also dependent on the street light spacing. It is governed by a variety of parameters, including the LED street light's illumination output, the street lamp's height, and the road's width. Additionally, towns may purchase a number of street lights based on their budget and then determine the spacing. In theory, the distance between LED street lamps should be 3.8-4 times the height of the poles, and street lamps should be spaced longitudinally at a distance of 30 to 50 meters. When power poles or other poles are present, the distance is between 40 and 50 meters. Consider combining the power supply pole with the lighting pole to save money. If the underground cable is utilized for power supply, the distance should be kept narrow to provide consistent lighting, which is typically 30 to 40 meters.
Additional Facts About Street Light Poles
a. The pole's height
The street light pole must be installed at the proper height to offer an adequate level of illumination. Street pole heights typically vary between 9 and 14 feet. In an ideal world, the street light pole would offer enough illumination without creating undue glare.
b. Consistent light intervals
While street lights aid in crime prevention, their primary purpose is to illuminate the path for walkers, cyclists, and cars. However, if one region is adequately lighted and the other area is pitch dark, this presents the potential for mishaps while the eyes adapt. Street lights must be spaced uniformly.
c. Context of installation
You'll want to pay close attention to the region around the street light post. For example, in a coastal environment, the poles are prone to corrosion due to the presence of saltwater. As a result, you may want poles with a specific finish.
d. Light Distribution
While a roadway may seem to be adequately lighted, elements such as trees or towering buildings may produce gloomy areas. This defeats the purpose of erecting the street lights. It is critical to keep these qualities in mind while determining the best location for street lighting.
e. Aesthetic Street light poles
Nowadays, most urban environments are identified by the aesthetics of their ornamental fluted lights and traffic poles. Recently, ornamental lighting poles have become popular for highlighting aesthetic features such as sculptures, gardens, and fountains. This street lighting proposal exudes excitement and has the potential to visually enhance an otherwise mundane urban location.
f. Maintenance of street lights
A conventional LED street light operates for around ten to twelve hours each day, and the streetlamp has a life expectancy of approximately 100,000 hours. As such, it is essential to replace streetlamps on a regular basis for more efficient illumination. Additionally, the poles utilized must be robust enough to hold the fixture.
