LED light source adopts low voltage DC power supply, high efficiency white light synthesized by blue LED and yellow, which has the unique advantages of high efficiency, safety, energy saving, environmental protection, long service life, fast response and high color rendering index. It can be widely used in roads. Cover available production, high temperature reached 135 degrees, low temperature reached -45 degrees.
LED light source advantages:
1, its own characteristics - one-way light, no light diffusion, to ensure the efficiency of light.
2, LED street lamp has a unique secondary optical design, the light of the LED street lamp shines on the required lighting area, to further improve the lighting efficiency, in order to achieve energy-saving purposes.
3, LED has reached 110-130lm / W, but there is still much room for development, the theoretical value of 360lm / W. The high-pressure sodium lamp luminous efficiency is increased with the increase of power, therefore, the overall light-efficient LED street lamp is better than the high pressure sodium lamp; (The overall luminous efficiency is theoretical, in fact, high-pressure sodium lamp above 250W light efficiency is higher than the LED lights ).
4, LED street light color rendering is much higher than the high-pressure sodium lamp, high-pressure sodium lamp color rendering index is only about 23, and LED street lamp color rendering index of 75 or more, from the perspective of visual psychology to achieve the same brightness, LED lights average illumination Lower than high pressure sodium lamp by more than 20%.
5, Low light failure, a year of light failure less than 3%, the use of 10 years still meet the road requirements, and high-pressure sodium lamp decay, about a year or so has dropped 30% or more, therefore, LED lights in the use of power design Can be lower than high-pressure sodium lamp.
