Hey there! As a supplier of 200w street lights, I often get asked about the mounting height of these lights. It's a crucial question because the right mounting height can significantly impact the performance and efficiency of the street lights.
Let's start by understanding why the mounting height matters. The mounting height affects the coverage area and the illumination level of the street light. If the light is mounted too low, it may create a concentrated beam of light that only covers a small area, leaving large portions of the street in the dark. On the other hand, if the light is mounted too high, the light may be spread too thin, resulting in insufficient illumination on the ground.
So, what is the ideal mounting height for a 200w street light? Well, it depends on several factors, including the type of area, the desired illumination level, and the beam angle of the light.
Factors Affecting Mounting Height
Type of Area
- Residential Areas: In residential areas, the main goal is to provide enough light for safety and security while minimizing light pollution. A mounting height of around 8 - 10 meters is usually sufficient. This height allows the light to cover a reasonable area without causing excessive glare to residents.
- Commercial Areas: Commercial areas often require higher illumination levels to attract customers and ensure safety. A mounting height of 10 - 12 meters may be more appropriate here. This height can provide a wider coverage area and better illumination for parking lots, sidewalks, and storefronts.
- Highways: Highway Street Light need to provide uniform illumination over long distances. Mounting heights of 12 - 15 meters are common on highways. This allows the light to cover a large area and provide clear visibility for drivers.
Desired Illumination Level
The illumination level is measured in lux. Different areas have different requirements for illumination levels. For example, a sidewalk may require an illumination level of 10 - 20 lux, while a parking lot may need 30 - 50 lux. The mounting height can be adjusted to achieve the desired illumination level. If you need a higher illumination level, you may need to mount the light lower.
Beam Angle
The beam angle of the street light also plays a role in determining the mounting height. A narrow beam angle will provide a more concentrated beam of light, while a wide beam angle will spread the light over a larger area. If you have a light with a narrow beam angle, you may need to mount it higher to cover a larger area. Conversely, a light with a wide beam angle can be mounted lower.
Calculating the Mounting Height
To calculate the mounting height, you can use the following formula:
[H = \frac{D}{\tan(\theta)}]
Where:
- (H) is the mounting height
- (D) is the desired coverage distance
- (\theta) is the half - beam angle of the light
For example, if you want to cover a distance of 20 meters and your light has a half - beam angle of 30 degrees, the mounting height would be:
[H=\frac{20}{\tan(30^{\circ})}\approx 34.64] meters
However, this is a simplified calculation, and in real - world scenarios, other factors such as the reflectivity of the ground and the presence of obstacles also need to be considered.
