Why are street lights high and low?

The reasons for the design of street lights are as follows:

1. Improve the lighting effect: street lamp design can improve the lighting effect. High street lights can illuminate a far area, so that pedestrians and vehicles can see the road situation in the distance, improving the safety of driving and pedestrians. Low street lights can illuminate the near area, so that pedestrians and vehicles can see the near road situation, convenient for pedestrians to walk and vehicles to turn.

2. Energy saving: Street lamp design can save energy by one high and one low. High street lights can reduce the number of street lights and reduce energy consumption. Low street lights can provide enough light in areas that need lighting, avoiding energy waste.

3. Beautify the urban landscape: streetlight design can beautify the urban landscape with one high and one low. High street lights can provide bright lighting effects at night, making the city more dazzling. Low street lights can provide a soft lighting effect at night, creating a warm atmosphere.

4. Improve traffic fluency: The design of street lights with one high and one low can improve traffic fluency. High street lights can provide bright lighting effects in the distance, so that the driver can see the road conditions ahead in advance, reducing the occurrence of traffic accidents. Low street lights can provide enough lighting effect in the near, so that the driver can clearly see road signs and traffic signals, improving the accuracy and safety of driving.

In summary, the design of street lights with one high and one low can improve the lighting effect, save energy, beautify the urban landscape and improve traffic fluency. This design can meet the lighting needs of different areas and improve the safety and aesthetics of the city.
