LED street lights are a cost-effective replacement for the traditional street lamps seen in many cities. LEDs generate less heat, are more resistant to breakage, and provide a brighter light than incandescent bulbs.
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. While street lights aid in crime prevention, their primary purpose is to illuminate the path for walkers, cyclists, and cars.
Calculate the distance between each streetlight pole using the given information.
The road's width (w) is 11.5 feet.
Pole Specifications: The pole stands at a height of 26.5 feet.
Each pole's luminaire: The luminaires have a wattage of 250 watts, a lamp output of 33200 lumens, a required lux level of 5 lux, and a coefficient of utilization factor of 0.18, a lamp lumen depreciation factor of 0.8, and a lamp lumen depreciation factor of 0.9.
The height-to-width ratio of the space should be less than three.
The distance between each pole is equal to (LL*CU*LLD*LDD) / Eh*W.
The distance between each pole is equal to (33200×0.18×0.8×0.9) / (5×11.5)
The distance between each pole is 75 feet.
Space Height Ratio = Pole Distance / Road Width
The ratio of Space to Height Equals 3. Which is smaller than the value specified.
Each Pole is 75 feet apart.
