What factors need to be considered when choosing the right street lamp?

The use of led street lights is inseparable from the correct choice. What are the performance factors of LEDs that need to be considered for proper selection of led street lamps?

In order to choose the appropriate LED street light, we first need to consider the luminous efficiency of the street lamp. The LED lighting technology is becoming more and more mature. The high-power LED light source can meet the luminous flux required by the general street lamp. The general high-pressure sodium lamp has a luminous flux of 100LM/W, and the commonly used high-power LED is 50-60LM/W. It can reach 80LM/W with the best LED chip from abroad. The higher the luminous efficiency, the better the energy saving effect. Choose one of the most important indicators of led street lights. In addition, the light decay of led street lamps is also one of the considerations. As a street lamp that needs to be used for a long time, it is absolutely impossible to use such a low-power LED. High-power LED (generally 30W or more) is selected, and its light decay is much better.

Led street lights are also factors we need to consider when choosing. This aspect is mainly lighter. Finally, what we need to understand is the heat dissipation of led street lamps. Because LED is a semiconductor component, its wafer is affected by temperature and reduced to the initial. At 30% of the luminous flux, the meaning of illumination will be lost, that is, the end of life. In theory, the life of high-power LED street lamps is 30,000-50,000 hours, but the important premise is that it has good heat dissipation.
