Adjustable LED street light refers to the street light made with the LED light source, which is of great significance for urban lighting energy saving. So how do we buy 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 lamps. The general high-pressure sodium lamp has a luminous efficiency of 100LM/W. The commonly used high-power LED is 50-60LM/W. It can reach 80LM/W with foreign LED chips. The higher the luminous efficiency, the better the energy saving effect. This is also the choice. One of the most important indicators of LED street lights.
2. Light decay
As a street lamp that needs long-term use, it is absolutely impossible to use low-power LED. High-power LED(generally 30W or more) are used, and the light decay is much better.
3. Self-weight problem
Due to the high technical content and complex composition of LED street lamps, some high-power lamp holders will weigh far more than ordinary high-pressure sodium lamps, so the requirements for the corresponding supporting materials are higher.
4. Heat dissipation
LED is a semiconductor component, and its wafer is affected by temperature and reduced to 30% of the initial luminous flux, it will lose the meaning of illumination, that is, the end of life, theoretically, the life of high-power LED street lamp is 30,000-50,000 hours, but The important premise is that it has good heat dissipation.
