Nowadays more and more street light are installed in two sides of city street and urban road since people request more frequent traveling and driving through road or street from one place to another. Anyway, to ensure the passage of street at night time, reduce the safety accident both for drivers and pedestrians, even brighten any beautiful landscapes or place, street light bring us all these needs in the dark.
Upon we discuss the street light, the first image come to your mind is those yellow or orange light produced by street lights powered by high pressure sodium light, now more and more street become whiter since led street light are replacing traditional hid light with natural white light, much higher lumen efficiency, longer lifespan, energy-saving features, but how to decide the wattages for led street light? Now we are introducing to you the factors you need to consider before confirm the wattage of led street light:
The wattage of led street light inevitably is influenced by the height lighting pole, for purpose of ideal and enough lighting brightness on the street ground, if the light pole is higher, wattage also need to be increased respectively, here are some information below:
|Pole Height||Wattage of led street light||Pole Height||Wattage of led street light|
You know you will see two lanes road, three lanes road, four lanes road, even twelve lanes road, different road is built at different width, road width may also decide the wattage of led street light. When you install same pole height and wattages of led street light, if the road is wider, the brightness of this wider road is lower, here are some data for your check:
|Road Width||Quantity of Lanes||Wattage of led street light|
|8-10m||2||20, 25, 30, 40, 50w|
|10-15m||3||60, 70, 80, 90w|
|More than 15m||4||100, 120, 150, 200w|
It is easy to understand that larger traffic volume road request higher brightness and wattage of led street light based on even the same pole height and road width, you can not confirm the exact wattage you need through traffic volume, but you can know the diminishing law. We are listing this factor on the basis of two aspects, one is main road, branch road and sub-branch road, one is city road, urban road and rural road below:
|Traffic Volume Comparing||Wattage of led street light|
|Expressway>Secondary road>Branch road||Expressway>Secondary road>Branch road|
|City road>urban road>rural road||City road>urban road>rural road|
