Now on the road to see the LED street lamp is used more and more, the main reason is because it green low carbon environmental protection, low power consumption, high luminous efficiency and long service life. So now the municipal road lamp upgrade will first consider the LED street lamp. LED technology with the progress of science and technology more and more mature, high power LED street lamp light source can meet the general street light needed. The average high pressure sodium lamp light efficiency is 100 lm/W, commonly used in high power LED is 50 - 60 lm/W, with abroad the best LED chips can reach 80 lm/W, the higher luminous efficiency, energy saving effect means that the better, this is also choose one of the most important indicators of lighting LED street lamp. Leds, however, does not have explicitly stipulated in the standard, so must be carefully confirmed when purchasing LED lights. Some lamps manufacturer in order to reduce the manufacturing cost, use only hundreds of 0. 5 w small power LED street light. However, this kind of small power LED light failure is very serious, its light failure and 80% of life is only 1000 hours. As the need for long-term use, so the street light is absolutely not allowed the use of this kind of small power LED, selects the high power LED Generally refers to more than 30 w) , the light failure will be much better.
