What Are The Advantages Of LED Street Lights

1. Its own characteristics-the one-way light, no light diffusion, to 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 area that needs to be illuminated, and further improves the light efficiency to achieve the purpose of energy saving.



3. The LED has reached 110-130lm/W, and there is still a lot of 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 luminous efficiency is theoretical, in fact, the luminous efficiency of high-pressure sodium lamps above 250W is higher than that of LED lamps. ).



4. The light color rendering of LED street lamps is much higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of LED street lamps is above 75. From the perspective of visual psychology, the same brightness can be achieved. The average illuminance of LED street lamps can be It is more than 20% lower than that of high-pressure sodium lamps.



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, while the high-pressure sodium lamp has a large decay, which has dropped by more than 30% in about a year. Therefore, the design of the power of the LED street lamp Can be lower than high-pressure sodium lamps.



6. The LED street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and energy saving under the condition of meeting the lighting requirements at different times. It can realize computer dimming, time period control, light control, temperature control, automatic inspection and other humanized functions.



7. Long life: It can be used for more than 50,000 hours and provides three-year quality assurance. The disadvantage is that the life of the power supply cannot be guaranteed.



8. High light efficiency: Using chips ≥100LM, it can save energy by more than 75% compared to traditional high-pressure sodium lamps.



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



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



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



12. Uniform light color: No lens is added, and the uniform light color is not sacrificed to increase the brightness, so as to ensure the uniform light color without aperture.



13. The LED does not contain harmful metal mercury and will not cause harm to the environment when it is scrapped.

Combining the above principles, the energy saving effect is significant, and it can save more than 60% of electricity instead of high-pressure sodium lamps.

Low maintenance cost: Compared with traditional street lamps, the maintenance cost of LED street lamps is extremely low. After comparison, all input costs can be recovered in less than 6 years.
