The selection of road lighting sources depends on different road grades and usage requirements. In the case of meeting the illumination requirements, it must meet the requirements of high luminous efficiency, high life, best cost performance, and meet the requirements of environmental protection and green in the new era. Led street lights are the best choice.
When the road lighting source is used in general roads and squares, if the color temperature and color rendering index are not considered, the best selection order is led street light , low pressure sodium lamp, high pressure sodium lamp, high pressure mercury lamp, self-ballasted high pressure mercury lamp, incandescent Lamps; if considering the life from high to low, the order is led street light, high pressure mercury lamp, high pressure sodium lamp, (external trigger high pressure sodium lamp and internal trigger high pressure sodium lamp), low pressure sodium lamp, self-ballasted high pressure mercury lamp, incandescent lamp.

In terms of light efficiency, the LED road lighting efficiency has exceeded 250lm/w, the conventional product is 130-150lm/w, the laboratory reached higher value, the low-pressure sodium lighting effect is 150 lm/W, and the high-pressure mercury lamp is only 50 lm/W. High pressure sodium lamp 100 lm / W;
Under the same light effect, compared with the low-pressure sodium lamp and the led street lamp , the start delay and life of the sodium lamp and the use of heavy metal are superior to the instant start of the LED street lamp without delay, energy saving and environmental protection, and high life;
Now the only disadvantage of led street lights compared to other kinds of light sources is that the investment is relatively large, but the cost of use is the lowest, and the most energy-efficient, cost-effective. For street lamps used for long-term lighting, the led street light source will definitely be Preferred.
