1.It is a unidirectional light source, without light diffusion, ensuring light efficiency.
2.The LED street light has a unique secondary optical design, which irradiates the light of the lamp to the area that needs to be illuminated, while this further improves the light efficiency to achieve the purpose of energy saving.
3.The luminous efficiency of LED has reached 110-130lm/W, and there is still a lot of space 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 lights is stronger than that of high-pressure sodium lamps.
4. The color rendering of LED street lights is much higher than the 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 lights is above 75. From the perspective of visual psychology, to achieve the same brightness, LED light is more than 20% lower than high pressure sodium lamp.
5. The light decay of LED light is small, it is less than 3% in a year, and it still meets 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 light can be lower than high-pressure sodium lamps.
6. The LED street light 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. It can be used for more than 50,000 hours and provides three-year quality assurance. But the disadvantage is that the battery life cannot be guaranteed.
8.Using chips ≥100LM, LED street light can save more than 75% of energy compared with traditional high pressure sodium lamps.
9. It′s easy to install, no need to add buried cables, no rectifiers, etc., directly connect to the light pole or nest the light source into the original lampshade.
10. Excellent heat dissipation control: The temperature in summer is controlled below 45 degrees, and passive heat dissipation is adopted, and the heat dissipation in summer is insufficient.
11. Reliable quality: All circuit power supplies use high-quality components, and each LED has individual overcurrent protection, so there is no need to worry about the damage.
