LED street lamp has a unique secondary optical design, can be LED street lamp light to the required lighting area, further improve the efficiency of the light, in order to achieve energy saving purpose.
The characteristic of itself, is it light partiality, no light diffusing, guarantee the light efficiency.
Unlike conventional street light, LED street light source USES low voltage dc power supply, by the blue LED with yellow synthetic efficiency white light, has its own unique advantages, can be widely used in the road.
High-power LED street lamps, light color is many taller than high pressure sodium lamp, high-pressure sodium lamp only around 23, color rendering index and LED street light is different, it is color instructions can reach more than 75, from the psychological point of view, vision to achieve the same brightness, that is to say, the LED light road lights are high pressure sodium lamp to reduce the average more than 20%.
LED lights use 10 years still meet the requirements of the road, because of its light failure is small, light failure is less than 3% a year, and the traditional high pressure sodium light failure is big, has fallen by more than 30% a year or so.
So, the LED street light on the design of the service power can is lower than traditional grid street lamp.
