1. LED is small in size and light in weight. It is encapsulated with epoxy resin, which can not only protect the internal chip, but also have the ability of focusing and transmitting light. Its service life is mostly between 50000-100000 hours.;
2. LED street lamps are equipped with automatic control energy-saving devices, which can meet the lighting requirements in different periods and reduce the power as much as possible to save electric energy. Using this feature, it can also realize the functions of computer dimming, time-division control, light control, temperature control and so on;
3. The light attenuation of LED street lamp is small, and the light attenuation is less than 3% in a year. Compared with high-pressure sodium lamp, the light attenuation of high-pressure sodium lamp is larger, which is about 30% lower in a year. Therefore, the design of LED street lamp can be lower than that of high-pressure sodium lamp
