Tips before purchasing led street lights
Luminous efficiency of led street light
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. However, LED standards are not clearly defined in this standard, so it must be carefully confirmed when purchasing LED street lights.
Light decay of led street light
Some merchants use hundreds of 0.5W low-power LEDs in order to reduce costs. However, the light decay of this low-power LED is very serious, and its lifetime of light decay to 80% is only 1000 hours. Therefore, as a street lamp that needs long-term use, 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.
Self weight problem of led street light
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. However, some LED street lamp manufacturers have reduced the weight of the LED lamp head as much as possible, from about 30 kilograms of the original single lamp head to more than 10 kilograms, and the weight reduction has further declined.
Heat dissipation of led street light
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. It is worth mentioning that the domestic manufacturers have adopted the world's leading needle cooling technology.
