The installation height of LED street lights depends on various factors, including the type of road, the lighting fixture's characteristics, the desired lighting levels, and local regulations. Here are some general considerations and requirements for determining the installation height of LED street lights:
Road Classifications: Different road types may have specific recommendations or standards for installation height. Major highways and busy arterial roads may require higher-mounted lights compared to local streets or residential areas.
Illuminance Level: The required illuminance level, measured in lux, is a crucial factor in determining the installation height. Higher illuminance levels may necessitate higher-mounted lights.
Light Distribution Pattern: The lighting fixture's optics and beam angle influence how light is distributed on the road surface. The distribution pattern should be taken into account when determining the installation height to achieve uniform illumination.
Spacing Between Fixtures: The spacing between adjacent LED street lights also affects the overall lighting uniformity. Proper spacing, along with the installation height, helps ensure adequate and consistent lighting on the road.
Mounting Method: LED street lights can be mounted on poles, walls, or other structures. Each mounting method may have specific requirements for the installation height.
Local Regulations and Standards: Different regions and municipalities may have their own regulations or lighting standards that dictate the acceptable installation height for LED street lights.
Safety and Aesthetics: The installation height should consider safety aspects, such as avoiding obstruction of signage and not interfering with utility lines. Additionally, aesthetics may be a factor, especially in residential or historic areas.
Light Trespass and Glare: Care should be taken to avoid light trespass (spillage of light into unintended areas) and glare. Properly designed fixtures and installation heights can help minimize these issues.
Environmental Conditions: Environmental factors like wind speed and seismic considerations may influence the appropriate installation height and pole strength.
Pole Design and Material: The pole's design and material should be chosen to support the weight and wind resistance of the LED street light fixture at the desired installation height.
