What is the street light on the road Why not use LED lights

The street lamps on the roadside usually use high-pressure sodium lamps or fluorescent lamps. There are several reasons why LED lights are not used:

First, the cost. Although LED lights have the advantages of long life and high efficiency, their manufacturing cost is relatively high. In contrast, high-pressure sodium lamps and fluorescent lamps have lower manufacturing costs, so in the case of large-scale use of street lights, the use of traditional high-pressure sodium lamps and fluorescent lamps is more affordable.

Secondly, technical problems. Although the LED lamp technology continues to progress, but in the field of street lamps, the traditional high-pressure sodium lamps and fluorescent lamps have been developed and improved over the years, its technology is mature and stable, able to meet the lighting needs of street lamps. While the application of LED lights in the field of street lighting is relatively new, its technology is still under continuous development and improvement, there are still some problems, such as light uniformity, color temperature adjustment and other challenges.

In addition, maintenance and management issues are also one of the factors affecting the choice. Traditional high-pressure sodium lamps and fluorescent lamps have a long service life and relatively low maintenance costs. While LED lamps have a longer lifespan, their maintenance and management is relatively complex, requiring specialized technicians to repair and replace them, increasing management costs and difficulty.

Finally, environmental issues also need to be considered. Although LED lights have high energy efficiency and low energy consumption, their manufacturing process requires the use of rare earths and other scarce resources, causing a certain impact on the environment. High-pressure sodium lamps and fluorescent lamps, on the other hand, have a relatively simple manufacturing process and a relatively small impact on the environment.

In summary, the roadside street lamps usually choose to use high-pressure sodium lamps or fluorescent lamps, and do not use LED lamps is mainly based on cost, technology, maintenance and management, as well as environmental considerations. With the continuous progress of LED lamp technology and cost reduction, the future application of LED lamps in the field of street lighting may gradually increase.
