What are the advantages of solar street lights in road lighting

　　 The current road traffic situation is so developed, especially on roads like highways, there are many cars coming and going every day, and there will be vehicles driving at night. Therefore, there are more places to use street lights at night, and one shot will be used for the whole night. Therefore, when solar street lights are widely used, they can not only ensure the requirements of road lighting, but also have many advantages in management, economy and lighting effects, which cannot be achieved by the previous high-pressure sodium lamps.　　 1. In actual lighting applications, solar street lighting has the characteristics of one-way, which allows the street lights to be illuminated at night, so that the light can be concentrated, so that the driver can better distinguish the actual road conditions. If a high-pressure sodium lamp is used, the irradiated light will be diffused. If it is rainy or foggy, it is difficult for the driver to distinguish the road conditions, which may cause accidents. So the advantage of this unidirectionality is very powerful.　　2. Because solar street lights have automatic energy-saving devices, they are very easy to manage. The energy-saving function of solar street lights is several times higher than that of high-pressure sodium lights. It can even be turned off automatically when lighting is not needed. This will save more energy, and of course it will become the first choice for urban lighting equipment projects.　　 3. The material of solar street light does not contain harmful substances such as mercury, so even in the case of wind and rain, no harmful substances will be decomposed. This is also a manifestation of environmental protection. Solar street lights have so many advantages, I believe that more and more such street lights will appear in people's lives in the future.
