Street light poles come in a variety of heights, shapes and styles and are designed for different purposes. The height of lamp posts used for public street illumination can range from 8 feet to 50 feet. Shorter lamp posts are used to light up gardens, which are approximately 5 feet to 9 feet tall and are used for home security and decoration. Street light poles must be tall enough to provide sufficient illumination to help pedestrians and vehicular traffic.
Only if the light pole is of the correct height, it can offer the appropriate lighting density. In narrow streets, only one side of the road is illuminated; however, wider streets require lighting poles on both sides of the road. Ideally, the total area illuminated by the lighting unit is approximately equal to the height of the pole. To determine the height of the pole and the distance between the poles, factors like speed limit, traffic density and crime rate in the area should be considered.
Where you place the light fixture is important in order to illuminate streets, roads, and sidewalks correctly. Also, the total light output and light distribution of the light fixture play a role in determining the height of the pole. The spacing of street lamps is determined by the lighting power of the lamp, the height of the pole and the width of the road. Street lights must be placed at consistent intervals to avoid accidents and for uniform illumination.
Solar street lights
Street light poles for solar lights usually have a height of 5 metres. All in one solar street light have in-built battery, panel, controller and LED and integrated solar street lights come with separate solar panels. The entire solar lighting fixture is fitted on top of the pole and therefore, the pole should be sturdy enough to support all these components. The ideal height for your solar street light pole can be determined by the power of luminaire. In order to avoid excessive glare, a lighting unit with a powerful luminaire requires higher height.
Thermally galvanized steel poles are treated and preserved properly before being used in order to withstand all types of weather changes and they usually last for around 40 years without rusting. After the solar lighting fixture is attached to the pole, the pole is placed inside the prepared hole and erected. The base of the pole is secured with concrete, which serves as the foundation of the solar street light. The preferred installation distance between the poles is 10 to 15 meters. This helps in avoiding too bright and too dark spots and aids in adequate distribution of light to the entire area.
Solar street lights poles should always be installed at an area where the panels can receive direct sunlight throughout the day. Consider nearby structures such as trees, shrubs, tall buildings, etc. as they can block sunlight from reaching the panels. The focus should be to avoid shadowy spots to help motorists and pedestrians navigate easily at night. Unlike traditional street lights, installation of solar street lights is unchallenging and simple. Solar street light units are wireless and do not require any trenching or cable pulling.
Each solar system is an independent lighting unit that works automatically from dusk to dawn without the need for manual intervention. If solar panel comes as a separate unit in your street lighting unit, attention should be given to fix it tilted at an angle for maximum sunlight absorption. Modern solar street lights are compact in design and relatively lighter in weight and can be installed on walls also. There is no standard height for lamp posts and each model of solar street light is different. If you are unsure about the correct height required for your solar street light, you may contact the manufacturer and ask for assistance.
