Analyze the performance and effect of solar street lights from several aspects

　　1. Energy saving is first and foremost to reduce the waste of the earth's resources and expand the use space of new renewable power. When choosing any new technology or new power, it is necessary to think about how to use power and the environment to protect it, and to develop real energy saving. Only one-sidedly use power output or operation as a measure of energy saving, and look at the energy consumption of one operation. The method, not thinking about the energy consumption of this kind of energy consumption in the production and transformation process, not thinking about the environmental protection, disposal of waste and other related matters after the use of power, will fundamentally violate the original intention of green energy saving.　　 High efficiency and energy saving means to obtain satisfactory lighting with less electricity consumption, and then significantly reduce the emission of air pollutants from the power plant, thereby achieving the intention of environmental protection. Solar street lights save electricity in some aspects, but we still need to look at energy conservation from the perspective of the whole, the system, and the whole. If it is in its life cycle, the energy saved should exceed the energy consumed by research, processing, and production, and it is the real energy saving. If it is not achieved, it can only be energy saving on the outside or in fact not energy saving in the national sense. Not just confined to appearance, but solar street lights have a fundamental energy saving. 2. Many solar street lamp manufacturers talk about the service life when they promote solar street lamps. The life of LED light source is very long. The solid cold light source is epoxy resin encapsulated. There are no defects in the lamp body such as filament light, heat accumulation, light decay, etc. , The service life can reach 60,000 to 100,000 hours, which is more than 10 times longer than that of traditional light sources. At the same time, solar panels also have a life span of 25-30 years. When it comes to high-pressure sodium lamps, they only have a life span of 3 to 5 thousand hours.
