Advantages of LED street lamps

Compared with the current ordinary high pressure sodium lamp street lamps, the advantages of LED street lamps are as follows:

1. Energy saving:

At present, the luminous efficiency of white LED is about 80lm/W, which can save 50%~60% of electricity compared with traditional high pressure sodium lamps. With the rapid improvement of LED efficiency, semiconductor street lamps have shown great potential in energy saving.

2. Low maintenance cost:

According to the current technical level and test results, high-power LED light sources can be used for 10 years without replacement, while traditional high-pressure sodium lamps need to be replaced once in an average of 1.5 years. The use of semiconductor light sources can greatly reduce maintenance costs.

3. Good color rendering:

The color rendering index of LED is high (75~80), people's reaction speed is fast, the road surface looks brighter, feels more comfortable, and the driver feels safer. The high-pressure sodium lamp has a narrow spectrum, poor color rendering (20~40), and feels dim.
