Why are LED street lights not installed on highways?
2022-04-14
With the development of urbanization, many roads have perfected lighting construction, but LED street lights cannot be seen on expressways. Why? Let me tell you why LED street lights are not installed on highways.
1. Reduce glare.
There is no need for LED street lights to illuminate pedestrians on the highways. If street lights are installed just to make drivers more aware of the road conditions, it is likely to cause glare pollution, and the brightness in the driver's field of vision is uneven, which is likely to increase the drivers' difficulties to recognize traffic signs, and even lead to traffic accidents.
2. The road condition is good.
Rural roads are equipped with LED street lights, mostly considering pedestrians or non-motorized vehicles, while highways are suburban roads between cities and cities, and between cities and rural areas, with guardrails and partitions, so basically there is no non-motorized vehicles and pedestrians,therefore it does not need lighting for them. And the highway roads are flat and in good condition.
3. There are enough reflective signs.
Even if there are no LED street lights, there is no need to worry about not seeing the guide signs. There is a perfect reflective sign system on the highways. People use reflective films made of glass microbeads and stick them on the traffic signs. They do not emit light themselves, but when they encounter the strong light of the headlights of a car, they will reflect the light into the driver's eyes, so that people can clearly see the lane guidance signs, lane dividing lines, center gaps, and roadsides appearance and guide cards, etc.
