The main points of buying LED street lights

1. Luminous efficiency: The technology is becoming more and more mature, and the high-power LED light source can meet the needs of general street lights. The commonly used high-power LED is 50-60LM/W, and a better LED chip can reach 80LM/W. The higher the luminous efficiency, the better the energy-saving effect. This is also one of the most important indicators for choosing LED street lights.

2. Light decay: The luminous decay of using low-power LEDs is very serious. Therefore, as a street lamp that needs to be used for a long time, such low-power LEDs are absolutely not allowed. Choosing high-power LEDs will have much better luminous decay. .

3. Self-weight problem: Due to the high technical content and complex composition of LED street lamps, the weight of some high-power lamp holders will far exceed that of ordinary high-pressure sodium lamps, so the corresponding support materials are more demanding. However, some LED street lamp manufacturers have tried their best to reduce the weight of the LED lamp holder.

4. Heat dissipation: Because LEDs are semiconductor components, when their wafers are affected by temperature and reduce to 30% of the initial luminous flux, they will lose the meaning of lighting, that is, the end of life. In theory, the lifespan of high-power LED street lights is 30,000 to 50,000 hours, but its important prerequisite is good heat dissipation.
