Technical requirements for electrical systems that are critical to the life of solar street lamps

The inherent characteristics of solar street lights, such as safety without hidden dangers, energy saving and consumption, green environmental protection, easy installation, automatic control and maintenance-free, will directly bring obvious advantages to the construction of municipal engineering. So what are the technical requirements for the electrical system of the solar street light itself? 1. Light source: High-power LED light source dedicated to solar energy is used, with a design life of ≥ 100,000 hours. 2. The controller adopts low power consumption, and has battery overcharge and overdischarge protection, battery open protection, load overvoltage protection, solar cell reverse connection protection, delay action, floating charge, temperature compensation, light control overtime control, moisture protection. 3. The battery adopts a 12V valve-regulated sealed maintenance-free battery specially designed for solar energy, with a service life of more than 5-12 years, a temperature range of -25℃--50℃, and a deep charge and discharge function. 4. The solar panel adopts imported solar cell chips, with a conversion rate of ≥17% and a lifespan of ≥25 years, which can fully comply with solar street lighting. In fact, as long as the solar street light project meets the above requirements, the life of solar street lights will be much longer than that of ordinary electric lamps. ; The average lifespan of low-voltage and high-efficiency tri-color energy-saving lamps is 6000h; the average lifespan of ultra-bright LEDs is greater than 50000h; the lifespan of special solar batteries is 2-5 years below 50AH; 3-7 years for 55-150AH.
