1. Its inherent characteristic - the unidirectionality of light, without light diffusion, ensures 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 LED has reached 110-130lm/W, and there is still great room for development, with a theoretical value of 360lm/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; The overall light efficiency is theoretical, but in fact, the light efficiency of high-pressure sodium lamps above 250W is higher than that of LED 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,.

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

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. It can achieve humanized functions such as computer dimming, time slot control, light control, temperature control, and automatic inspection.

7. Long service life: can be used for over 50000 hours, providing a three-year quality guarantee. The drawback is that the lifespan of the power supply cannot be guaranteed.

8. High light efficiency: By using chips with a capacity of ≥ 100LM or higher, it can save more than 75% energy compared to traditional high-pressure sodium lamps.

9. Easy installation: No need to bury cables or rectifiers, directly connect the installation to the lamp pole or nest the light source into the original lamp housing.

10. Excellent heat dissipation control: In summer, the temperature is controlled below 45 degrees Celsius and passive heat dissipation is adopted, resulting in insufficient heat dissipation guarantee in summer.

11. Reliable quality: All circuit power supplies are made of high-quality components, and each LED has a separate overcurrent protection, so there is no need to worry about damage.

12. Uniform color of light: Without a lens, uniform color of light is not sacrificed to improve brightness, thus ensuring uniform color of light without aperture.
