Does LED street light consume a lot of power? Based on the 120W LED street lights, the one -hour electricity consumption is 0.12 degrees, and the street lights generally need to turn on for 12 hours a day. A 120W LED street light needs to consume 1.44 degrees a day, and a 120W street light requires 525 degrees of electricity per year. about. In first -tier cities, the total power consumption of LED street lights is an amazing number.
Some netizens will ask questions, solar street lights can be installed in rural areas. Why do not use solar street lights in big cities? This is because solar energy is energy saving, but it also has its disadvantages. One is that solar street lights are affected by the weather. The local geographical climate and weather conditions directly affect the use of street lighting. The rainy days will affect the lighting lights, causing the illuminance or brightness to meet the requirements of the national standard, and even the lights appear. Because the light is insufficient during the day, the light time at night is too short. The second is that the cost of solar energy is high, and the third is that the efficiency of solar energy is low. The conversion efficiency of solar photovoltaic batteries is about 15%to 19%. In theory, the conversion efficiency of silicon solar cells can reach 25%. Building blocks caused reduced efficiency. Fourth, life expectancy and cost are relatively low, the cost of installation is high in the early stage, and the cost of later maintenance is high.
Although LED street lights consume more power than solar energy, they have their own advantages. In general, first- and second -tier cities are more suitable for LED street lights with higher stability and meet the needs of lighting. Local, more energy saving and environmental protection
