120w Wifi control street led light
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. However, LED standards are not clearly defined in this standard, so it must be carefully confirmed when purchasing LED street lights.
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. 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.
