Street lamp foot cage knowledge

With the acceleration of China's urbanization process, the street lamp cage has gradually entered people's field of vision with its advantages of directional light emission, low power consumption, good driving characteristics, fast response speed, high seismic performance, long service life, and green environmental protection. A new generation of energy-saving light source that has the most advantages in replacing traditional light sources in the world. Therefore, the street lamp cage will become the best choice for energy-saving renovation of road lighting.
The color rendering performance 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 illuminance of LED street lights is more than 20% lower than that of high-pressure sodium lamps on average, it can be used for more than 50,000 hours, and it provides a three-year quality guarantee. The disadvantage is that the service life of the power supply cannot be guaranteed. LEDs do not contain harmful metal mercury and will not cause harm to the environment after being scrapped. It can replace high pressure sodium lamps and save more than 60% of electricity.
Compared with traditional street lights, the maintenance cost of LED street lights is very low. After comparison, all investment costs can be recovered in less than 6 years.
