The difference between LED street lights and conventional street lights is that the LED light source adopts low-voltage DC power supply and is a high-efficiency white light synthesized by GaN-based power blue LED and yellow. It has high efficiency, safety, energy saving, environmental protection, long life, fast response speed, high color rendering index, etc. Unique advantages, can be widely used on roads. The outer cover can be made, the high temperature resistance can reach 135 degrees, and the low temperature resistance can reach -45 degrees.
