led street light manufacturer: what are the advantages of LED street light compare with traditional high pressure sodium lamp ?
1. Energy saving: LED light source efficiency has reached 110-130 lm/W, and there is still a lot of Space for development, the theoretical value of 250 lm/W. The luminous efficiency of high-pressure sodium lamp increases with the increase of power. Therefore, the overall light efficiency LED street light is stronger than high-pressure sodium lamp, and high-power LED light source is used to cooperate with high-efficiency power supply. The actual lighting effect is more than 60% more than that of high-pressure sodium lamp. With the rapid improvement of LED efficiency, LED street lights show great potential in energy saving.
2. Color rendering is good: the light color rendering of LED street light is much higher than that of high pressure sodium lamp, the color rendering index of LED lamp is high (75~80), and the color rendering index of high pressure sodium lamp is only about 23. And the road looks brighter, feels more comfortable and drivers feel safer.
3.Long lifespan : LED street lamp light decline is small, one year light decline less than use 10 years still meet the road illumination requirements, and high pressure sodium light decline, about a year has dropped more than 30%, therefore, LED street lamp in the use of power design can be lower than high pressure sodium lamp, but longer life.
5. Green environmental protection: LED does not contain harmful metal mercury and other heavy metals, will not produce pollutants, high-pressure sodium lamp or metal halide lamp in the end of life to cause harm to the environment。
6.Low maintenance cost: according to the current technical level and test results, the high power LED light source can be used normally for 10 years without replacement, while the traditional high pressure sodium lamp will be replaced once a year and a half on average. The use of LED light sources can greatly reduce maintenance costs。
7.High Safety performance: LED street lamp is a low voltage product, of course, this is for solar LED street lamp 12 V is enough, the LED street lamp of electricity or 220 V voltage.
