The improvement of the building of urbanization promotes the development of lighting projects, which makes the solar street lights complete the role transition from function to decoration. The solar street lights not only play the role of illuminating facilities on the roads, but beautify the cities.
For most of the street lights in cities were produced with low standards and have worked for a long period. In addition, the light posts were corroded seriously and the light given out is weak, which not only influence the safety of citizens, but bring security problems. The municipal administration will replace the old street lights with the advanced solar street lights instead, which can not only meet the needs of energy-saving and environmentally protection and improve the intensity of illumination, but provide convenience for people going out at night.
The installation quantity of solar street light of China has increased gradually in recent years. According to the preliminary measurement, the market size of the solar street light of China has reached 2.3 billion yuan in the year of 2015.
The former high voltage sodium lamps are updated to the energy-saving LED lights, which brings energy-saving and high-efficient road illuminating. Compared with the high voltage sodium lamps, the solar street lights have good illuminating effect and lower capacity. So on the basis of same electric capacity, the solar street light will be brighter.
As the new generation of green illumination facility, the solar street lights have been applied all over the world. With the recovery of global economy, the solar street light will be the high-efficient illuminating facility with broad development prospect.
