LED street lamp replacing sodium street lamp is an inevitable trend.

We have always seen the city roadside street lights are yellow light, which can be used to distinguish the color of the road objects will interfere. The reason is that the lights are used in light is sodium lamp, sodium lamp working principle is to rely on metal sodium vapor glow.
In all kinds of traditional electric light, the sodium lamp can not be done with the color rendering of both. For street lamps, the most important thing is to ensure that the object to see, to ensure traffic safety, color discrimination is not so important, the opposite to the car is black or red for the car to avoid pedestrians no difference.

Therefore, the use of more light efficiency, longer life of energy efficient LED streetlights, the same electricity consumption can make the lights cover more roads, but also reduce maintenance costs. But this does not mean that color rendering is unimportant. With the advent of LED light source, LED street lights can emit white light, and white lights more efficient, looks brighter, longer life, sodium lantern is gradually eliminated from the field of streetlights.
Now with the maturity of LED light source, the field of street lamps will gradually be the color of the good LED light source occupation.
