What is the performance of LED street lamps? What are the advantages compared with the traditional high-pressure sodium lamp?

LED street lamp is a kind of street lamp with LED as light source. Compared with traditional high-pressure sodium lamps, LED street lamps have the following advantages:

1. High energy efficiency: LED street lamps have high energy efficiency, which can convert electric energy into light energy in a higher proportion, saving energy and reducing consumption than high-pressure sodium lamps.

2. Long life: The life of LED street lamps can usually reach more than 50,000 hours, far exceeding the life of high-pressure sodium lamps. This means that the maintenance cost of LED street lamps is low, which reduces the frequency of replacing lamps and reduces the maintenance cost.

3. Adjustable color temperature: LED street lamps can adjust the color temperature according to needs, from warm white light to cold white light to meet the lighting needs of different scenes. However, the color temperature of high-pressure sodium lamps is usually too high to be adjusted.

4. Small light attenuation: LED street lamps have small light attenuation and small brightness change during their service life, and can maintain a stable lighting effect for a long time. However, the light attenuation of high-pressure sodium lamp is large, and the brightness will gradually decrease with the extension of service time.

5. Dimming: LED street lamps can adjust the current to realize dimming and intelligent lighting control. However, the high-pressure sodium lamp can only be switched on and off by a switch, and it is impossible to achieve fine dimming.

6. Environmental protection and energy saving: LED street lamps do not contain harmful substances such as mercury and will not pollute the environment. At the same time, due to its high energy efficiency, the use of LED street lamps can reduce energy consumption and carbon emissions.

7. Fast response: The response speed of LED street lamps is very fast, and it can be lit instantly without preheating time. High-pressure sodium lamp needs a certain preheating time to achieve the best brightness.

To sum up, compared with the traditional high-pressure sodium lamp, LED street lamp has the advantages of high energy efficiency, long service life, adjustable color temperature, small light attenuation, dimmable, environmental protection, energy saving and quick response. Therefore, in the field of modern lighting, LED street lamps have become an ideal lighting choice.
