What are the most significant advantages of LED street lights


LED street lights are different from conventional street lights. Its light source adopts low-voltage DC power supply. It has the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response, and high color rendering index. It can be widely used in urban road lighting. The advantages of LED street lights are shown in the following nine aspects:
1. Its own nature-the unidirectional light, no diffuse light, can ensure the efficiency of light.
2. The LED street lamp has a unique secondary optical design, which irradiates the light of the LED street lamp to the required lighting area, further improving the lighting efficiency.
3. The luminous power of the LED can basically reach 130lm/W or more, and there is still a lot of room for development, and the theoretical value has reached 360lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power.

4. The color rendering of LED street lights is much higher than that of high pressure sodium lamps, and the color rendering index of high pressure sodium lamps is only about 23, while the color rendering index of LED street lights is greater than 75.
5. The light decay is small. The light decay in a year is less than 3%, and it can still meet the road requirements after 10 years of use. However, the high-pressure sodium lamp has dropped, and about 30% has dropped in the whole year. Therefore, the LED street lamp is better than the high-pressure sodium lamp in the power supply design.
6. LED street lights have automatic control and energy-saving devices, which can reduce power, save energy, and are more likely to meet the requirements of different lighting cycles.
7. Long lifespan: LED street lights can be used for more than 50,000 hours and provide a three-year warranty. The disadvantage is that the service life of the power supply cannot be guaranteed.
8. High luminous efficiency: Compared with traditional high-pressure sodium lamps, LED street lamps can save energy by more than 75%.
9. Convenient installation: no need to add buried cables, no rectifiers, etc., it will be directly installed on the original lamp housing of the street lamp pole or the nested light source.
