1. The characteristics of LED street lights themselves - the unidirectionality of light, no diffuse light, ensuring lighting efficiency;

2. LED street lights have a unique secondary optical design, which illuminates the light of LED street lights to the required lighting area, further improving lighting efficiency and achieving energy-saving goals;

3. The light source efficiency of LED has reached 100lm/W, and there is still great room for development, with a theoretical value of 250lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power, therefore, the overall luminous efficiency of LED street lamps is stronger than that of high-pressure sodium lamps;

4. The color rendering performance of LED street lights is much higher than that of high-pressure sodium lights. The color rendering index of high-pressure sodium lights is only about 23, while the color rendering index of LED street lights reaches 75 or above. From a visual and psychological perspective, when reaching the same brightness, the average illuminance of LED street lights can be reduced by more than 20% compared to high-pressure sodium lights (referring to the British lighting standards);

5. The light attenuation of LED street lights is small, with a light attenuation of less than 3% in one year. After 10 years of use, it still meets the requirements for road illumination, while the high pressure sodium light has a large attenuation, which has decreased by more than 30% in about one year. Therefore, LED street lights can be designed with lower power consumption compared to high pressure sodium lights;

6. LED street lights have automatic control energy-saving devices, which can achieve maximum power reduction and save electricity while meeting lighting requirements at different time periods;

7. LED is a low-voltage device that drives a single LED at a safe voltage. The series of products have a single LED power of 1 watt, so it is a safer power source than using a high-voltage power source, especially suitable for public places (such as street lighting, factory lighting, automotive lighting, civil lighting, etc.);
