1. Energy conservation is primarily the reduction of the maximum limit to the dross of the earth's resources and the expansion of the use of new renewable power. When choosing any new skill or new power, it is necessary to think about how power application and environment are protected, and develop real energy saving. Only one-sided power output may be used as a measure of energy saving. The way, do not think about the energy consumption of this kind of energy consumption in the production and transformation process, do not think about the related matters such as protecting the environment and disposing of discarded materials after the use of power, it will fundamentally violate the original intention of green energy conservation.
Energy efficiency means achieving satisfactory lighting with less power, and then significantly reducing the emissions of air pollutants from power plants to achieve environmental protection. Solar street lights save power in some aspects, but we still need to look at energy, from the whole, system, and all.
If it is in its life cycle, its power to save beyond the energy spent on research, processing, and production is the real energy saving. If it can't be achieved, it can only be energy-saving or in the national sense, it is actually not energy-saving. It can't be limited to appearance, and solar street lights have fundamental energy savings.
2. Many solar street lamp manufacturers talk about the service life problem when propagating solar street lights. The life of LED light source is very long. The solid cold light source epoxy resin is packaged. There is no defect in the lamp body, such as filament light, easy burning, heat accumulation and light decay. The service life can reach 60,000 to 100,000 hours, which is more than 10 times longer than the traditional light source. At the same time, solar panels also have a lifespan of 25 to 30 years. When it comes to high-pressure sodium lamps, it only takes 3, 5 thousand hours.
