Description

technical field [0001] The invention belongs to the technical field of street lamps, and specifically refers to a solar energy phase change heat storage temperature difference generating circuit lamp system. Background technique [0002] As a necessity for modern roads, street lamps have an important impact on road investment in terms of energy consumption and lifespan. The power consumption of street lamps mainly depends on the supply of city power. With the development of new energy, some areas have adopted measures such as demonstration projects to promote the application of new energy products, mainly based on wind and solar complementarity and solar energy. Among them, the wind-solar hybrid street lighting system is mainly composed of wind turbines, solar panels, wind-solar hybrid street lamp controllers, wind-solar hybrid battery and LED street light sources, several main components, light poles, solar panel brackets and other related accessories. However, the current...

Problems solved by technology

However, the current solar street lamps mainly use photovoltaic street lamps and wind-solar hybrid street lamps, which have the following main problems: (1) The cost of photovoltaic panels and batteries is high, resulting in high initial investment; (2) The service life of the supporting batteries is short, and most of the replacement cycles for two years

These potential problems lead to high maintenance costs in the later period, fail to achieve the effect of energy saving and emission reduction, and even cause serious waste of resources
